I have a brand new OS .91FX laying around and I wanted to try my hand at Pattern flying (I usually try and fly my 3D or IMAC planes pattern like..). I think the best option for ARF is the GP Venus II since the Excelleron 90 is gone?
Anyway - I see that most folks are using a YS110 or a OS 120AX. On a 8 - 8.5 lb plane the OS 120AX seems overkill (I have one on my Funtana X100). Am I wasting my time trying to do pattern maneuvers with a .91 2-stroke on the Venus II?
