the hard part just going to be throttle management. If you can accelerate going vertical ther is no need to start prop experimenting. I have noticed that apc's give better vert. than MA .but Ma give a better mid range in the hover. For the Pizzaz on an a 4cyc 70 ma 13x6 gave me best hovering. I try to tell those learning to "watch the tail" and don't try to be to high.Especially on a fun fly. You should have enough throw in the rud/elv to recover and pull it back to vert from ??? 10-15degrees off??? Also try to do it from a stall turn aditude, where you would kick the rudder, apply power and "catch" the plane. then watch you tail. Also if your not truly vert. is almost impossible.The plane looks almost like its leaning towards you(depth preception)

remember step up to each manuver. most people want to torque roll before they can prophang and before they can do tailslides before they can stall turn.....

OH YEA, PRACTICE,practice
