I have a Zen 30. Good flyer until time to land. It has to come in pretty fast. Trying to come in slow and it is a tip stall disaster. I watched the pattern planes in Ohio and they come in like a feather. I'm building my second one as tip stall landings has finally taking it's toll. I would like to practice, practice, practice with this plane and then go on to my Osmose 70. Is it OK to put ailerons in a little up position on a switch for some washout and get the nose up and speed down a little? Would this also help with the tip stalling?
What you are talking about is a spoileron as Mike stated, if you have them drop instead of going up they would be flaperons. Either way, a flap or spioler is going to increase the rate at which the model descends. You might be better off using a flaperon instead of a spoileron if stalling is your issue.
Washout is bit of twist in the wing where the trailing edge of the tip is higher than the trailing edge of the root.
