162" Art Scholl Super Chipmunk
Hey Guys, Well I've been gathering info for sometime now. I have decided it was time to start the build. This build will be a slow one, as I'm still needing a few things.
This is my first scratch build and the first time I've ever worked from enlarged plans. The plans are the old Ohio RC plans (81") that where doubled. Power will be a DA-150 with cans if they can be made to fit. 12 servos should do the job. I will also have smoke. I'm estimating the weight around 60lbs.
I will be making a few mods from the plans. I'm not trying for perfect scale just going to try and get rid of the Sport scale look of the plans. The wings will be built as is. I've talked with several builders that say the wing is a good airfoil. I will be making it a three peice wing though. It will break at the ailerons.
The fuse will be rounded out. The Ohio kit had very flat sides and no wing fillets.
The first pic is of the main spar. It is two 1/4"x48" plywood.
Second is of the bottom spar. I cut a groove in it with my table saw. This will make the shearwebs stronger.
Pic three is of the lightning hole cut in to a 1/8" ply rib. There are only five of these.
Pics 4 and 5 are of the wing tube holes.
And finally the wing test fitted together. No Glue yet.
That is a 36" yard stick laying on the wing.
More pix later.
