Title: 1/2A
Post by: jakepF1D on November 29, 2011, 10:42:22 PM
Wally Miller (Mr. EZB) has proposed a new fun event called 1/2A.  As the name suggests it's basically half the size of an AROG model, but without the ROG part.  The rules are as follows

Max wing area = 15 in^2
Max stab area = 7.5 in^2
Minimum weight = .010 oz

Andrew Tagliafico sent me plans of his first prototype and that's what I used to build this model.  This one came out a little heavy at .0116 oz with most of the extra weight in the prop.  If anyone else is interested a few people will be bringing these to fly at the Kibbie Dome this summer (assuming it happens).

Very pretty airplane!
I like the mylar covering much better than the condenser paper used for A6.

I agree that is a pretty aeroplane but what is the purpose?  I would have thought that Indoor needs another new class, with no original or challenging features, like it needs a hole in the head.  Perhaps the idea is to have a class for each indoor flyer then everyone can be a winner. :)

I can see John's point though. There are ministicks, A6's, pennyplanes, and so on. Seems like the 1/2A would be smaller than an A6 but bigger than a ministick? What was the original intent if I may enquire?

My understanding is that Wally doesn't have regular access to a decent indoor site.  He devised this model to be small and light for flying in small sites.  Without the wingspan restriction of mini-stick you can create a model that flies much better and is capable of handling torque without barrel rolling.  It's also lighter which should enable longer flight times.  Beyond that you would need to ask Wally since it's his creation.  

I personally built one to mess around with at local contests.  A couple other local guys have them and the site we fly in isn't good for anything larger than a pennyplane or EZB.  I could build a mini-stick, but they're a pain to trim and I don't really care for them.

Ah - a new can of worms - or maybe just a rehashed old one. I think if you like the idea of this model and want to build one then go ahead and have a blast. If you're looking for something new for your local club to play with then go ahead and give it a shot. If you want to start a new AMA class with an event at the NATS then you're probably wasting your time.

Yes Ministicks are pretty ridiculous. Yes A6 should allow Mylar covering. Yes LPP is too restrictive. Yes F1M is wonderful but hardly anyone flies it. Yes F1D is awfully hard. But starting a new event and getting nationwide or worldwide support for it is the longest of longshots.

I DO like the model, but if I were going to campaign for a new event it would probably be an "A" class (30si) model without the huge wood sizes, small prop and paper covering of the A6. In the absence of such a logical event I'll continue to fly and enjoy all the current "beginner" events.


Title: Re: 1/2A
Post by: jakepF1D on December 01, 2011, 06:43:57 PM
I don't believe Wally has any intention of proposing this as an AMA sanctioned event.  It's just something that a few local people picked up and it's now an "official" event at our contests.  It will also be an "official" event at the Kibbie Dome if Andrew is able to pull together the contest.

Regarding other events; I think they're all hard when you boil it down.  Too many people are too good at pretty much every event to make any of them easy.  Some models might be easier to build and fly than others, but extracting a winning time from that model is something altogether different.  Just because I can quickly toss together an F1M doesn't mean I have any hope of beating you in a competition  :)

Post by: jakepF1D on February 08, 2012, 05:53:04 PM
A quick update on this model.  The original model in the pictures was damaged so I built a new one that was right at the minimum weight (290mg).  This past weekend I set a site record at 10:03.  The model flies very nicely with none of the torque roll problems associated with mini-sticks.  It just spirals up to the ceiling and begins bouncing around.  The motor will take a few hundred more turns so I should be able to reach 11 and maybe 12 minutes in our Cat II building.  I know some here aren't in favor of more events, but it's become extremely popular and competitive at our local contests.

Post by: Maxout on February 09, 2012, 11:38:42 AM
Jake, while I disagree with you on the stability issues with ministick--the only rule about them I dislike is the motorstick length limit--, I do find your model quite interesting. Are you finding the solid motorstick to be better than a rolled one? Also, has anyone tried a VP prop yet?

By the way, what I really like about ministick is that you can pack them into a tiny box in a suitcase. They travel better than any other class of models I've encountered. I reckon this would be true of the 1/2A's as well, though the box would have to be longer to accomodate the longer wingspan.


Title: Re: 1/2A
Post by: jakepF1D on February 09, 2012, 12:01:53 PM
I've actually considered making a VP prop for it, but making something that small and light is challenging.  The smallest music wire I have is .006" which might be too heavy for a spring considering the rubber and torque involved with something this light.  Down the road I want to experiment with it, but for now I'm just going to bang the ceiling and see if I can get to 12 minutes.

The torque roll issues I see with mini-sticks are related to the low aspect ratio required by the rules.  I always see minis helicoptering.  I prefer a model that flies like a real airplane, but perhaps some have mastered the torque issues on mini-stick.  I have yet to see one that could handle any reasonable amount of torque.  I keep adding torque to this model and all it does is climb faster.  I haven't been able to make it helicopter yet.

The solid MS is easier to make and it's still quite easy to hit the minimum weight.  I haven't had any problems with stick bow or twist which leads me to believe a rolled tube isn't necessary.  If I do build a VP prop I will probably make one because I'll want to offset the heavier prop and the launch torque will be much higher which could create problems with a solid MS.


Title: Re: 1/2A
Post by: Olbill on February 09, 2012, 02:15:24 PM
I made a VP hub for 35cm that uses the prop shaft as the spring. I didn't get it working very well before dropping 35cm due to a lack of time. Larry Coslick was interested in this idea and made similar VP's for F1M and IS. He seems to like the idea. I think his Cat 2 F1M record was set with this type of VP.

For 35cm I didn't have any adjusters so it was very light.

Thanks, Jake. Interesting information there.

The torque roll issues I see with mini-sticks are related to the low aspect ratio required by the rules.  I always see minis helicoptering.  I prefer a model that flies like a real airplane, but perhaps some have mastered the torque issues on mini-stick.  I have yet to see one that could handle any reasonable amount of torque.  I keep adding torque to this model and all it does is climb faster.  I haven't been able to make it helicopter yet.

Ok, got it. This is the problem with a lot of ministick designs out there. Good high performance designs have high wingposts (this is a function of some computer simulation I've dabbled with) which carry the side benefit of better roll stability. That is not enough in itself, however, because you also have to have enough rudder area to prevent the barrell rolling tendency. Another way of achieving this is to use a droop boom, which produces a very stable model capable of handling a lot of torque. I've built three droop boom minis and all of them handled power well. Anyway, you need the rudder area as low as possible. High mounted rudders do not work well on minis for some reason.

I do have two minis that tend toward barrell rolling at launch, but they are intentionally short-coupled to get a layout that seems to perform better. I think my droop boom model could fly longer than them since it handles power so well, but it has yet to make the leap.

If there's sufficient interest, maybe we should start another thread on ministick trimming. Seems to be a common malady. There are a lot of folks who struggle with trimming them, and I've banged my head against the wall enough to finally learn how to tame them. Or you could just build Alan Cohen's design, which always seems to fly perfectly (where I got my solution from).

This is really good idea.  I've seen drawings of very early VP designs that used this principle, but I completely forgot about them.  On lighter models like this that might be the perfect solution.  I'm going to experiment with this idea and see if I can put something together before the next contest.  I might be the cause for a new rule.

I might build a mini-stick down the road, but they aren't very popular at my local contests.  Only 1 or 2 people fly them versus 4 or 5 people flying 1/2A.

What I have in my head is quite a bit different than your design, but essentially works the same.  My design would have adjustable preload tension.  I also have an idea for limiting high pitch that would add almost no weight.  I'll post pictures once I have a prototype built.

I just returned from a meet held at the Kibbe Dome in Moscow,ID. For those who think that this class might be a joke and not needed, for the challenge of building small, there is a lot of performance in these little jewels! The model aircraft in many instances fly much better than the A-6, plus if you like to innovate and experiment and do not mind working with an optivisor a bit, then this class should be on your list to try, I certainly will! :)


Title: Re: 1/2A
Post by: Olbill on July 15, 2012, 11:16:52 AM
In spite of my earlier comments that may have sounded too negative I really like this class. I hate restrictive rules which is one reason I've flown F1M for so long. I love my A6 but hate the class. I've come up with workable solutions to the problems in the A6 class and have a model that is basically just wind it up and let it go and it always does well. But the beauty of this class (as I see it) is that there are so few restrictions on the model design. You can build a real indoor model with real indoor construction and it will be easy to transport and easy to handle. Those scraps of 5/99 and 3/02 should make lots of high quality motors whereas LPP motors make a really huge dent in your rubber supply.

Many of us think that there are too many official classes.  Perhaps when the number of indoor participants was high, that was okay.  Today, when the number of indoor fliers is down significantly from the past, it seems that having too many events dilute the field of participants.

I like the FAI system of F1D, F1M, F1L, F1R.  That's it.

Few things in my honest opinion concerning indoor free flight duration make sense. What keeps an F1D in the air with the prop spinning so low an rpm?

The weight of the 1/2A comes down to .284 grams, or 284 mg. There were a number of different types of aircraft flying, since the AMA rules require at least two models for an official event, many flew for pleasure and enjoyed every moment.

I learned enough about indoor during my trip to Moscow, ID, that I'm probably forever "hooked" on the activity. This was a meet, funfest, contest, and the gathering of like minded friendly model airplane enthusiasts all rolled into one happening, which made for a very enjoyable experience!

I could be mistaken, but most if not all classes or event minimum weights are in grams. I was a bit confused about the 1/2A, some told me 303mg well others had the same confusion. One ounce in grams comes up with an odd number. Since this class of models is in a transitional phase, a minimum weight of 300mg or .3gms would be less confusing. I don't mind the mixing of metric and non-metric if it works for those involved. :)

Post by: jakepF1D on July 16, 2012, 03:35:05 PM
You need to remember that the event was created by Wally Miller.  He's been around....a few years.  Way back when it was all imperial all the time.  It isn't hard to do the conversion.  Just type" .01oz to grams" in a Google search and it will do the conversion for you.  I use Google to do all my metric conversions.

i started working in a machine shop, and all the imperial measuring threw me for loops at times, as most things in the rc world is in metric, with the exception of spans. then reading about indoor building its back to imperial thousandths but weighed in grams. similar mix for most rc models, they weigh in grams for smaller models but measure spans and areas in inches.
seems so intertwined that it will never be just one set of numbers on the ruler  :P

Re: Early VP's and using the shaft wire as the spring. Here's a pic of an original hub by Jeff Annis, as drawn and described in an NFFS Sympo Report from circa 1977. I believe that it was that article that pushed Bernie Hunt and Dave Pymm to develop the mechanisms that they used at West Baden in 1980.

Post by: Maxout on August 29, 2013, 04:40:03 PM
Finally got around to making one of these. It's a little beefy at 350 mg, but the rolled tube is worth it. not as stable as advertised--it does a lot of helicoptering in the first 2 minutes of flight--but looks really nice with the prop turning much slower than it would on a ministick. Did 5:06 in my office with the new 7.5" flaring prop I made, and then it did 7:24 in the garage this morning (14' peaked roof), so I'm happy with it. I just wish that VP's were going to be allowed. It climbs for about 5 1/2 minutes...probably enough to make it to the top of Lakehurst.


Title: Re: 1/2A
Post by: jakepF1D on August 29, 2013, 04:46:39 PM
The last one I built is currently in pieces on top of a scoreboard, but it never helicoptered for me.  I had to use a couple degrees of downthrust, and the model did require a little backoff to accomplish that.  I also used a very light solid motor stick that bowed a little at launch torque.  The next one I build will use an even lighter stick so I can fly in our Cat 2 building without backoff.

Mine did 10 minutes in a Cat 2 building and 12 at Kibbie Dome.  I'm pretty sure with a little work they're capable of 11-12 minutes Cat 2 and 14+ at Kibbie Dome.

Post by: Olbill on August 30, 2013, 03:20:22 PM
I'm looking for something to fly instead of F1L so this might be just the thing. I was considering ministick and may still go that route but the 1/2A is more appealing than the mini. And it's not that I think F1L is a bad class - it's just that every time I go to a big contest I either have a new problem or I have an old problem that I thought was fixed.

Jake - are there material limitations in the rules you use?


Title: Re: 1/2A
Post by: jakepF1D on August 30, 2013, 05:57:48 PM
I think the only restrictions are no VP props and no microfilm.  At this point the rules are somewhat informal, but nobody will complain if you use carbon fiber or boron.

Are you planning to make the trip to Kibbie again next year?  If you do you should have some good competition in this event.  I have a new model in process for the upcoming local indoor season, and several other WMC people are actively flying this event.

I hope to go to Kibbie next year as part of a geological sight seeing tour. Most of the trip we made from Portland to Kibbie went thru areas that were sculpted by the Glacial Lake Missoula floods that happened some 15,000 years ago. My wife is interested in all of the trip except the Kibbie part so I'm not sure how that's going to work out.

Jake, well I reckon my helicoptering must be because I don't believe in backing off. ;)

Post by: dslusarc on September 04, 2013, 07:54:13 AM
I can see why no VP but why no microfilm? The model has a minimum weight, wing area, and stab area restrictions. Microfilm was the heart and soul of indoor model aircraft for so long I find it sad when it get restricted in so many events. Any weight differential is so minimal due to the limited area in this class I don't understand why limit people to using mylar? I personally love microfilm, a sheet cost pennies and will cover probably 5 models this size. Anyhow this event reminds me of a event called Scraps we use to fly in Cleveland about 20 years ago but this event sounds better as you can make longer spans. Maybe we need a postal contest for the winter?

If you decide to do a postal I'll try to get one built.

I think the "no microfilm" rule is pretty much like the "no mylar" rule for A6. For people who like to think the less rules there are the better the event.


Title: Re: 1/2A
Post by: jakepF1D on September 04, 2013, 04:04:01 PM
I need to double check since the rules aren't formalized, but I thought they said no microfilm.  The reasoning is the same as the no microfilm rule for other events.  Theoretically it makes the event easier for beginners.  In reality I had to add a little ballast to reach the minimum with an OS film covered model, so I don't think microfilm offers any advantage.  I personally think it would be a big mistake to cover with microfilm for any Cat 1 or 2 flying because you need to scrub the ceiling.

I recently talked to Ed Berray, and the current plan is to run a 1/2A postal at the same time as the mini-stick postal.  I don't have dates or details, but it sounds like it should happen.


Title: Re: 1/2A
Post by: dslusarc on September 04, 2013, 07:47:31 PM
In events with no weight limit I can see an advantage by the use of microfilm. But in weighed events it never made sense to me. Seems like there was an anti microfilm movement at one time when rules were being drafted :o If it is not allowed then so be it, it will not stop me from making one.

Nick,

Sounds good. Thanks!

Now back to my 1/2A model. I went to the gym to fly today and these fly rather well. The flight speed is not as fast as I though it would be for such a small model. I got one test flight about 5 minutes then went to do one more flight with a few extra turns and it was up at the ceiling in about 50 seconds and hit a few girders and went off in a completely different direction right to the wall, and flew above the ducting and landed on top of it against the wall. The section of the ducting it is on is about 3 feet wide and it is square and I can not see the model. So for the moment the model it is lost. The next flying session in two weeks I am going to try a hook and string to try and fish it out but it looks grim  :(

Hi Don
I  fly in a sports hall with heating panels suspended from the roof and I do occasionally get on top of them, in the same way as yourself.  I made a bracket which would hold the top section of my long pole at right angles to the rest of it and fixed a small wireless video camera to the pole, looking along the section held at right angles to the pole.  I can use a small monitor at eye level to steer the pole and recover the model.  I would suggest that you fix a small compact camera to the top of a pole and set it to record video and have a sweep around where you think it may be.  That would steer you in the right direction for your recovery operation.
Good luck with it.
Rodney

I actually have a small wireless one but was not with me at the time as I never expected that to happen! But I will be back to try and get it down. Hopefully it will still be there at the next flying session. I have never been in the gym when the heaters turn on.

I'm in the process of building my fourth 1/2A after losing the first three.  They do tend to get hung up fairly easily.

This is a great suggestion. Anyone have a suggestion for a model to look for?
Preferably streamable to iPad or Laptop?

Regards.

It has been a year now but I was able to get my model down a few days ago. I bought a C-GO1 HD Camera from Horizon Hobby on black friday sale for only $36. It has an app that you can use an ipad as the viewer screen so put the camera on one pole and used another to get it out. I had to use a loop of masking tape to get it but the only damage is a cracked prop spar and the rubber motor was dry rotted. I am amazed it sat there for a whole year undamaged. Only a few feet away was a volleyball.
