This is a good motor for the price and performs very well in a 2kg warmliner.
Unlimited vertical climb at good speed with 15x10 carbon folder on 5 cells.
A mix of full and part throttle takes a 2250 mah batt down to storage voltage after a 7 minute flight.I have been using this motor for over a year now and it could't perform any better. Using it in FVK Kamalot hotliner with 4s Nanotech and 16 x 13 follder, reaches 1000ft in 9secs. Excelent.I got this motor to use in a TT Siren. The motor is a tight fit and required a spacer to fit correctly. You need a prop adaptor with a long shank as the shaft is a bit short.
Ive static tested the mot on a zippy 4S 4000 30C, 14x8 folder, 100Amp Yep speedy = 8670 RPM, 38Amps, 16.5V, 637W after 1min, 884W peak.
Cant try anything else at the moment as this is the largest folding prop I have and I plan to run on 4S 2450 Hacker batteries anyway because they fit the air frame.
Very nice at any price. Tested on the bench with an Xoar 16x8 wood prop.
3s 38 amps and 382 watt
4s 72 amps and 1090 watt
5s 82 amps and 1425 watt.
This motor is rated at 1750 watt.
Motor runs smooth and cool. Should be fine on a 16x10 static, or maybe 16x12 in the air if used with caution. Very impressed.
Built in fan will allow motor to be run well above 1750 Watt in short bursts.
Red brick 200 amp esc, none opto, corrected manual programs ok.
I use this motor on a Graupner Speed (eq. Wilco) 1,7m hotliner, AUW about 1,5kg (?). Setup 4s nanotech 2.6, prop 13x8, K-Force 150A opto. Good power, runs very smooth, motor - batt - esc completely cool after flight. 5sec bursts pull up to more than 200m. Will be very fine on 5s (ordering now) and perhaps will even tolerate a bigger prop.Would a 60amp esc be ok using 4 cell 2200 or so? I bought the big esc but doesn't fit in my siren.This motor is perfect for what it was designed for.
A warm/hotliner. I'm running it in a pacer glider with13x8 carbon folder on
5s. Super smooth super power cool running...
The point wasn't misconstrued-we just ask that Hobby King make 28mm 5s and 6s motors for our 70mm class jets for additional performance.This motor should have been a high KV inrunner with or 5S AND @ 28mm diameter. Alot of guys (like me) are needing 5 and 6S 28mm motors that can fit in the 70mm class jets. Hobby King has too many 7 volts when they should be 5 or 6S instead. Start making then Turnigy and you will get more engine customers.
