This is an image of my Boomer P-30 design. I market this kit through my website www.cbmodeldesigns.com

I've posted this a bit on the SFA site, so I hope it doesn't bore those of you who have already seen it there.

You can check out the details on my website. You can also view or downlaod the construction manual if you wish.

The kits will build underweight if done per plan. These models are a blast to fly and experiment with-competition or just sport flying.

HI All,

I was thinking [could be bad] that I will build a new P/30 ,the one I have by Dave Platt is as good they come and I know it will go OOS this gives me a reason to build a new one.

I had one of these P30s DT and did not come down, it just keep going and we never got it back. I think the best way to get it down is to pop the wing.

HI All,

I was looking though some of my P30 kits that I have,and this jumped out at me and before I do anything to it does anyone know of this P30?

I think some one gave it to me for some D T fuse at a free flight contest in VA. if anyone has info. on this model good or bad could you let me know?

The name of this P30 is Tail Firster.

Bob,

 I've heard it's a good flier. Never built one myself, though.

I think that was a full size plan in Aeromodeler years ago.. If so mine built and flew quite well. I was scared about the big rudder tip plates but I managed to get them on straight.

The AEROMODELLER canard P30 was HEATHER'S BROOMSTICK from memory about 10 or 12 years ago.
Bill and Heather Thomas in the Brisbane Freeflight Society built one or two of them back then and it was accepted by AEROMODELLER to be a full size plan.
It was quite a good flier in Heather's hands with help from her husband Bill.
Unfortunately Bill passed away 6 or 8 years ago and Heather retired from flying.
Both delightful people that also had a strong interest in motor sport also.

Hello Everyone... just a line to let you know that I am a new member to this site. I didn't know of it... and I am glad I came across it. I have belonged to NFFS and it's site for some time now. I am a big fan of P-30 and have done pretty well flying competition... although not as good as some of the well knowns. But the main thing is the enjoyment of this class.
It's good to be here!

Hi Craig, Welcome to the group. Sorry to answer late, but for some reason, I wasn't getting notified of replies to threads I subscribe to. Just got back on the forum to look around.

My first successful flying model, thanks to many on several groups was a P-30, the "One Night 28". It would never win a contest at a whopping 50+ or so grams with no rubber in it, but it flew well, and even got up to 90 seconds. Probably a light thermal. I've never competed, but may soon try, and the P-30 class, as you said, is a good place to start. Will have to check when I get down to Eloy, if they take entries at the check in table. Might just try to fly my NJAPF which has been very consistent. Competition is ok, but just being there and meeting everyone is the best part.Have fun flyin', and let us see some of what you put together. We're all very interested.

My type of model! I have a weakness for out of the rut designs. I recall an article about this creation, i believe in FM or maybe AAM some time back.l BMJR still in business?

As I've NO competition/endurance models (yet), I'd be interested in obtaining a "Tail Firster" - I think it's neat. Wouldn't care whether it is competitive or not as I fly for fun.

Yes BMJR is still in business and still sells the Tailfirster. I know of a person that flys it in competition and does well with it but he is one of the top flyers in most AMA events.

Have fun..

Derek, Sorry for such a late reply. I must say that your model definitely stood on its tail and kept going. I guess that's the difference between a rubber motor wound properly and what mine does. Mine maybe goes up at a 45 degree angle for a few seconds, then levels out and just cruises. You're the brave sort to fly in wind. Smiley

Well, I don't know about being brave, I just wanted the exercise of the chase! As to winding rubber motors, I started in free flight competition with Wakefields so I learned early on to wind the snot out of them. I still wind motors pretty hard even in classes that don't need it!

As do I. Even a sport model has a maximum flight potential .. and I feel ANY model should be flown to its limits every time.

 Yep...I fly mine with 6 strands of 1/8 rubber at 9.6 grams before lube and wind between

 1200 and 1400 turns. Of course you don't to do this without use of a blow tube!

Sounds about right! P-30's are tons of fun with that kind of power. It's between a 10-11 on my torque meter.

When I used to fly P-30s a lot back in the 70s, I used a rubber stripper and cut .250" down to .160 (4 strands). Liked that better than using 5 strands of 1/8". Last P-30 I made was John Kamlas Marie that used 6 X3/32". Great flyer if the motor was really pushed.

I've been listening to you chaps talking about how many winds you get on your motors. I must have a bad batch of rubber, as 6 strands of 1/8 rubber, well lubed, explodes at around 970 winds. Could be I'm not stretching it 100 times its length to get those massive winds. Grin I just don't have luck with putting heavy turns on my motors. They break too easily. Will have to be happy with around 900.

I must admit I've never had 6 strand motors go as far as 1200-1400 turns - how good was the torque, Craig?

I usually get somewhere between 1000 and near 1100 dependent upon batch and courage for that 'extra couple' ; your 970 may not be out of line for your batch, Caley, and could indeed be producing more torque than a 'softer' motor carrying more turns. I think you have commented previously about having to stretch out further when winding, so there could indeed be some more turns available. 'Coming in' too fast can also reduce number of potential turns.

Heat could be the culprit. I find that the hotter it is the fewer turns before the explosion. Under good conditions it seems that 1200 is my upper limit. Some batches of rubber are thinner than others, also. That allows relatively more turns due to the longer motor.
