Along with a 40 MHz system, the engine must be optimally suppressed, so with 3 capacitors and 2 reactors in the motor cable, the controller is working properly. Inadequate or no suppression cause engine stumble or poor control characteristics.
Together with a 2.4 GHz system reaches a filtering with a capacitor paralell from the engine. This type of system is much electrical noisy and more reliable than earlier systems.
Properly suppressed and receiver as far away from the motor, the controller works just fine, even in the lower speed range. About Suppressing electric motors are found sufficient literature on the internet, but one has to read and observe. This chapter is unfortunately too often neglected, and then you wonder that the system is not going well and complains about the poor quality of the controller. There is none of controller fault, but the sensitivity to interference of the receiver.
Another tip. If the motor runs at full voltage and standstill (motor blocked) over 10 - take 15 amps, 16 amps with an additional fuse is sluggish in the battery supply useful because the controller does not provide overload protection. In this case, simply blows the fuse only.
