3 - Sensorless brushless Systems

There is more manufacturers of sensorless brushless systems. Why? Because those systems were used primarily on RC planes and boats. Now, manufacturers propose their products for RC cars because ESC are well adapted to RC cars needs. In this area, Feigao, Hacker, Kontronik, Lehner, LRK, Mega AC, Model Motors, MP JET, PJS, MGM, M'Troniks, Plettenberg, Schulze, Überall Model provide ESC or motors and some both (Hacker)

Hacker

C 40 Series The C40 series motors have been specially developed for High RPM, High Temperature applications.

R/C Racing Cars and Smaller Helicopters that use 6-10 NiMh cells or 2-3 LiPoly are excellent candidates for the Hacker C40 Brushless System.  These motors are Super Efficient , but produce Huge amounts of Power (300% more than a Brushed Modified!!!). Available in both "T" (Short) and "L" (Long) versions. The C40T Motor bolts directly into any "540" Mounting location and feature a 1/8" Shaft.

The C40L is a Longer Motor that also uses the "540" mounting pattern and a 1/8" shaft.
