Hey, whadayamean, the raven 40 is a great flying plane. I have about 150 flights on mine. 33oz per sqft helps with the snaps (gad can't believe I said that). How many planes will snap roll with just a slight pump of the elevator? It's like having a snap roll switch. Non of that monkeying with rudder elevator and ailerons to get a good snap roll. I like doing aerobatics and replacing all of the roll elements with snaps and I just have to pump the elevator to do them. Just make sure you are not pointed straight down with less than 100 feet of altitude. You probably won't make it unless you push down elevator. It doesn't seem to snap with down. The engine in the thing has never quit. If it did I'm sure the plane would just quit flying and fall down.
