Hey Guys! I'm waiting for my Harrier 90. I am high Elevation: 6184' (1885m). I also want a 2 stroke engine for econimical reasons. I've been thinking about the 120AX. But i really don't know if it will work well hovers and everything. This is my first 3D. I'm jumping from a Super Stick, and a Mustang PTS Trainer. Both OS .46FX. Could you send me your thoughts about an OS 120AX in a Harrier 90 at 6,200 ft elevation? What Prop? Or maybe going all the way with an OS 160??? Also what prop? And last but not least...break in suggestions. Thanks in advance!
