Ruddog RP540 540 Sensored Brushless Motor (21.5T)
Bought this motor for the USGT class. Set it to 6 amps on a motor analyzer which ended up being 52 degrees of timing and and it is on pace with all other motors on the track. This motor stays cool as well and after a 10 min run is only at 130 degrees. For a motor this cheap its just as fast as my hobby wing v2 and v3 motors as well as my Fantom works motors. Really impressed with the quality and would recommend this motor to anyone.

Ruddog RP540 540 Sensored Brushless Motor (21.5T)
had this is my 4 tec rally car all last summer, motor handled boost great and never got hot even on 90 degree sumer days. was looking for something comparable to a titian 12t brushed and although this motor wasn’t quite as fast it was still very quick especially on the bottom end. good motor for a great price
