I have a 70" Revolver (newly built) needing nothing but a motor and prop to finish her up (6s, 100wESC in place). I'd like to go with a size .80 equivalent, and would like to stay under $80USD for the motor. I will be flying aerobatic and am looking for 120w/lb+ or at least a 1.15:1 T/W ratio (plane is just under 10lbs auw).
I prefer HeadsUp RC, and have had a couple of good experiences with the Firepower line (smaller sizes). Thus, the Firepower 80 Sport is my first choice. However, they continue to be out of stock (I've waited ~10 days already) and I can't get a solid ETA. I'm not sure if I can wait weeks to fly this gal!
I've done some motor/prop homework and have a pretty good idea what I could use, but would like some help from some of the experienced electric guys here.
I've also looked at the Turnigy Aerodrive SK3 - 5055-430kv and the Welgard (Grayson) GH4130-07 450kv. Depending on the motor, I'd be looking at a prop (I think) in the APC e 15x7 up through 16x8 range. The Firepower 80's specs (a great baseline) are as follows:
Firepower 80 Sport 5065
Voltage: 12-34 (4-8s)
Current: 65a max ~60sec
Watts: 1400w max ~60sec
Mount: 300mm spaced / 4mm screws
Should I be patient for the Firepower (Great HURC Service)? Go with the Turnigy (In stock in USA)? Grayson (Close to me but mixed reviews on the Welgards)?
Are there any other motors in the $80 or less price range that are .80 equivalents you guys recommend?
Thanks & happy flying!
