Chris, check out this thread.

I also had a question regarding throws for flaps. I got some interesting feedback telling me that flaps could have the opposite effect I wanted if they were too far aft of the CG. (Lowering flaps on landing approach would actually bring the nose DOWN.) I haven't tried it yet. I had a mishap at the field and fried my electrics right out of the plane!

My advice is to try it with flaps up, then stage 2, stage 3 probably is way too radical.

Best of luck 2 u.
