Brilliant quality very fast in my turnigy td10 with a 120a hk esc. maybe the connectors would be better on the back of the unit for space and fitting cooling easier.

I bought 2 of these to test on a touring 1:10 Himoto Nascada car (full alluminium setted). Tested with a ESC X-Car HK 45A 6pins sensored.
Wiring a multi-function speed meter (between ESC and Engine sensor) here follows my data test obtained after 30minutes strong race with a straight 22mt long (at full throttle for any lap)

Room temperature: 14C
Test time: 29.50 minutes
Power: turnigy 5000mah 40C 2S lipo Hard Case Pack
Car weight: 1.47kg (including battery)
Engine start test temperature: 22C
Engine end test temperature: 31C
Esc start test temperature: 23C
Esc end test temperature: 28C
Max accelleration: 4.9 G force
Max decelleration: 4.67 G Brake force
Fastest speed: depending from transmission gears, tyres and asphalt (87Kph with my setting)
0 to 100kph time: depending from transmission gears, tyres and asphalt (0,67s with my setting)

All datas about lap time and more others, are not important to value the quality of ESC and motor, then i didn't show them.

Consider that you can modify more of these results with right gear set of transmission and electronically by ESC programming card, anyway i can say that coupling X-Car engine (8.5t in my case) and X-Car ESC series (45A in my case), your 1:10 touring car will give you a full time satisfaction races, so i just can add "buy them and enjoy yourself, your touring/drift cars will surely thanks yo

Bought this motor for my Tamiya M04-M. Running it witha a 45A Esc, 2S and 21t gear instead of the original 17t, for highspeed runs.
No heatproblems at all, although the high gearing. Will get back here after some speedmeasuring. I hope I can get a good quality video too.

Great motor, great value.

Great motor! Ordered it with the HK 80a ESC for my 2WD Arrma Mojave - and wow, it moves! Actually too powerful. I need to lower the timing on it, and get better rear tires to make it stick to the track better! Great performance, and i've run it for two weeks now... no issues!

Have a Xray T3 2010, spur 78. Esc 45A HK 2S and 6600mah nano tech. Drive on a fast outside track. Started off with 25 teeth, hand warm almost cold. Currently driving 31 teeth and meassure 46 degree C. This motor cant get enough!! Super quick and just order a 34 teeth pinion. Driving 12 packs so far. Very happy with this motor.

Bought 2 for 2 drift cars. Running both with the X-Car 60 amp ESC. Both cars run great with this combo. One is a belt drive and the other is a shaft drive and they both have crazy power now. Excellent motor. Highly recommended.

Great motor for medium performance but even if not altering the timing, just unscrew the case bolts anyway and add some medium strenght threadlock

Motore magnifico e mostruoso! usato su un auto RC 1/10 Touring, ho dovuto abbassare al minimo la potenza motore. Peccato che per una pietra fra corona e pignone si spezzato l'albero porta pignone:(...ne comprer uno identico!!
Qualit do 4, perch le viti erano lente, ma in complesso Ottimo.
