Bruce thanks for the info. sounds like they are not always a bad idea.

when they are up like spoilers, I suppose the main wing has less lift, but I wonder if it could then maintain a higher angle of attack without stalling an allow a slower forward speed?

I have a 3-position switch on my tx, might try figuring out how to assign it and go try out a few different settings. I just wanted to make sure there was a realistic potential for success and this would not necessarly be a doomed experment.
