Use about 50% flaps in your radio give or take 5% depending on any roll tendencies. I ended up with 55% on the left flaperon and 50% on the right for trimmed flight.
This makes quite a difference for landing - now I can get that nice touchdown without catching a wing. It is also fun to do slow flybys with the flaperons down. It goes without saying that the fast flybys are also fun.
Setup is a Himax 2812-1080 outrunner with 2" Dubro spinner, APC 9 X 7.5 SF prop, PHX 25, and a TP 2100 3s lipo.
