Ted,

Sure you can modify any plane you want, itīs impresive what someone can do to a model with a little imagination....however, this is a knoledge that comes with experience.... Plans have their reson to be, itīs all in the C.G you can play a little with it but not too much, cuz a sailplane with an incorrect C.G simply wont fly.......it becomes a wild horse in the air.....so take this very in mind when making changes.

Sailplanes With polyhedral wings dont like ailerons, because itīs the dyhedralīs work to bank the plane when turning on the rudder...... adding ailerons on this type planes, will result in veeeeery slow respond to them.....so in this cases itīs better to stick to the rudder....also the wing profile is very important, because a non simetrical wing = to a slow plane = to a slow aileron response......


Ohh and never change the basic design of the wing, or it wont fly right, if you want to make it go faster, add some aunces at the C.G you will be thrilled of the difference.....

Big birds donīt usualy like ailerons, specially if the the wing is non simetric......because the glider responds very slowly to ailerons......
sailplanes are critical , changes they are sometimes NOT welcome on gliders if done incorrectly, they simply dont fly if changes are barely drastic....you will figure this out after a while....

my advise is to stick to your plans, and after a little experience is achived get yourself an aileron desing.....they are very fun and you will find that the wing profile is different ( more symetric ) as they need a bit more speed to make the ailerons take effect...

safe flying!

P.S. I have some pic, of modified gliders, I could E mail them if interested....Flat wings and stuff like that.
