<div>I bought a plane off Craigslist and am rebuilding it. This is alarge vintage style trainer. It is a gasser that has a wingspan of 96", alength of 88", and before I started the rebuild, weighed about 14lbs.I figure it will be able to handle just about any weather and be a perfect plane to teach my 2 sons how to fly.

I have a question about some flaps that are under the wing trailing edgenext to the fuselage. They are in the position that you would traditionally have flaps, are very large, but only go down.The top of the wing does not move. I'll post some photos later.

Are they flaps, orsomesome kind of airbrakes?Should I hook them upto the flapschannel where they can be adjustable, or should I hookthem up to the retracts channel where they will beeither up or down?

These things are controlled with 2 servos connected with a y-harness. The ailerons use 2 servos and I only have a 6 channel radio, so I'll be using all channels available to me. I've not quite figured that part out yet either.</div>
