ParticipantWell, the building season is upon us and my first project is complete! It’s the 1/2 A Country Boy for the 2010 One Design competition. This was built from a BMJR laser cut kit that assembled very well. I was very surprised to find out that the weight of the plane came in over 8 ozs. 🙁 😯 Stab covering is Polyspan light, Wing covering is std. Polyspan, Fus. is finished with one coat of Z/poxy cut 50%, than 4 coats of 50% thinned dope as the wing and stab are. As you can see in one of the pics. I had to move the motor way out front to acheive the 80% CG as stated on the plans!! Initial test glides look very good! All in all I do like the design of the Country Boy and if scratch built could probably drop at least an oz. off the weight.

ParticipantNicely done-
Few comments here-
If you want to take some weight out of the airplane how it is right now, take a look at the systems. By that, I mean the timer and the engine mount. Going to a 1/2A tick off timer will definately take some weight out.
Also, go to a shortie engine mount. You can make a spacer to get the engine out to the position needed for the proper CG. Then, either use a short tatone style mount or, better yet, get a mount that replaces the backplate. Or, go to a filled nylon style mount. I think you will be surprised at the weight difference in the mount alone…
I like the color scheme- good luck with it

ParticipantHey Scott, John makes some points. And some are good, too! 😆
You could make a wooden spacer that would shift the motor forward and the use a backplate mount. The different timer would help, if you had one.
The Polyspan is a bit heavy for a 1/2A. If the stab was tissue, it would probably need less nose weight.
7.5 oz is a realistic target. I don’t think you’re too far into oblivion.It looks real purty, but haven’t I seen that color scheme somewhere?

ParticipantJohn/Dan, thanks for the observations! I originally had a radial mount on it but when I had to move the engine out so far I dragged out this mount from the archives. Dan, I too like the color scheme HA! I’ve decided to use the white, red, and blue on my gas planes and yellow and red on the electrics so I can identify in the sky and on the ground.

ParticipantOK Scott, here is a hint on how to identify the different types:
Gas planes are noisy and oily and leave residue on you and your clothing.
Electric plane sit there quietly and collect dust, which is EASY to remove.11/13/2009 at 9:40 am #48126George Reinhart
ParticipantDon’t forget the smoke if you get ’em in the water, Dan.
We missed you at Seguin last week end.Cheers!

ParticipantHere is a photo of the one I built in the early 1990s from an original Clemcraft kit. I have another of the original kits, but I think it might turn out a little heavy. I lost the first one before I got around to weighing it. I won’t make the mistake of running the DT line uncovered under where the stab rubber bands wrap around the fuse again!

ParticipantDenny….
I see the checkerboard covering and it remineded me of a Starduster 600 I did with all red/black checkerboard- Blue fuselage- Probably oneof the ugliest airplanes I ever made!
Besides that, looks nice…Another for the Dock fleet!!

ParticipantYew guys just wait ’til yew see the checkerboard stuf that ‘Cover Boy’ Troutman has produced.
He’s got a Cyclon powered Maverick at less than 8oz!01/23/2010 at 12:12 am #48132Craig G
KeymasterComing together. This is the first FF gas model I’ve ever built, was a fun build. No idea what it weighs. I’m going to add some color to the fuse and fuel proof, then it’s ready to go.

ParticipantTwo very pretty models ….

ParticipantIt’s a nice build….what did you cover it with? Good luck on your first power flights…

KeymasterIt’s UltraCote Lite, transparent white. Not much of a color scheme but then I rarely get carried away when finishing models.
Couldn’t help myself and just gave it a couple of tosses in the yard, it glides better than I expected…
