    Well, 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.

    Nicely 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

    Hey 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?

    John/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.

    OK 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.

    Don’t forget the smoke if you get ’em in the water, Dan.
    We missed you at Seguin last week end.

    Cheers!

    Here 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!

    Denny….

    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!!

    Yew 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!

    Coming 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.

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

    It’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…
