Smithy the Hart fuselage looks great - that should sand up very nicely.

That's a nice fuselage Neil.

Interesting Jon. Is that a small coreless motor?

Hi John, yes it's a little 4x8mm with a worm gear.

I've been working on a circuit for a DT. It will run off a 15mAh lipo so in theory it could be around a gram and a half all up.

Hi Smithy, Here is a quote from your very first post in early August.
" I used to build models when I was younger, but I have never built a balsa wood model..."
And already you have produced what is an outstanding build of the West Wings Hart (Which is far from being a beginners model!!!!).
Well done.

Thank you very kind, I still have time to mess it up but whatever happens I’ll have learnt a great deal from the build. One of the reasons I have cut my own parts rather than using the kit parts, was so I could learn from the mistakes and go back to build the kit when my experience is greater. I have an easier build waiting in the form of a Vintage Model Company Cessna 140 which I thought would be easier, particularly to learn the process of trimming.

Thanks Jon.It should be competitive weight wise with Viscous timers and much more consistent. Hmm - how would it compare with a capacitor timer?

I'm not sure. The small damper I supply is only 0.3g with the lugs cut off. I made a PCB version yesterday that was 1g including the connectors but excluding the battery and mousetrap. I think a band burner version would be lighter still - especially with onboard power for an E20.


Hmm - how would it compare with a capacitor timer?

Do you mean capacitor power for the spin off motor? I've played around with using 5.5V capacitors for a band burner version and the weight vs lipo is just about comparable. It would make life easier if you didn't have to worry about lipo charging. There are some issues with cap power which I need to iron out (the leak factor) but I've designed and improved circuit which might work. The reduced voltage (2.7V) for a spin-off motor may be another factor.

BLUEBIRD ORNITHOPTER Flights -  12 good pics from 27 pics taken.
First of two posts.

      At  1:00 PM  today, I grabbed the Bluebird Ornithopter and Trapper and some clay, and off we went to the Cricket Field in Jackson Park.   We had some good rain in the last few days, and the grass came back to life.   The wind was  7 mph from the East gusting to 11 mph.

Pic #1     3085     Jackson Park flower garden in full bloom.
Pic #2     3087     Nice summer day.
Pic #3     3089     Way up high at the top of the screen!!!
Pic #4     3090     Slicing through the sky.
Pic #5     3092     Climbing.
Pic #6     3093     Nice contrast of blues.

Second of two posts.

     The Bluebird is still all trimmed out.   I got some really nice high flights - mostly 10 to 15 seconds though, on 70 winds.   But I got in my flying fix.

Pic #1     3097     Flat wings.  Spit and Hurri in the background.
Pic #2     3098     Almost straight up.
Pic #3     3100     Twice as high as the trees, way out there too.
Pic #4     3101     Flaring up.
Pic #5     3106     A nice pic out in the Baseball Field.
Pic #6     3108     And another pic.

The temp was  68 deg F,  feels like  70 deg F.

Fall is coming,   .......    Get out and fly.   Cheesy

Slowed down a bit doing small details, a few bits on the gun turret, bomb window, bending wires for undercarriage and wheels. Had to leave it there as I have promised my better half I’d finish the decking before winter arrives and it’s too crazy to work outside usually because of rain and wild wind here in North Wales.

Thanks, the part I’m dreading is covering with tissue as I’m sure it’s about practice so the first attempt is normally a bit of a disaster.

A bit of practice on a sample frame and you'll be ok. Just don't try to pull the tissue too tight. Look up the advice here on covering in teh workshop section and also read Andrew Darby's article on the Vintage Model site.

Thanks for the advice I had thought I’d have a practice first, this was supposed to be my practice piece but now it looks ok I need a practice, practice piece.  Cheesy

 Grin  while the engines are drying on my twin p40, i'm cutting out parts for my airline martin mauler.  i blew up the parts 29 % so span is now 14 inches with a 5 inch prop.

Hi Jim, good to see someone building the Mauler.  I scanned and uploaded the plans/parts as 11x17" sheets - if you print them at 100% size you should get the original's 15" wingspan.

As far as what I did airplane-wise today, I fixed a broken landing gear on the Wedell-Williams (again!) and took a family photo of my jetcats, including the two new F-111Bs I built for WestFAC's carrier jetcat event.

Cheers,

Mike
