The rules need to be updated to current standards...they're living at least 5 years in the past. Cars are the ONLY part of r/c where sensored motors are still being used...we stopped making sensored ESC's about 7 years ago! The #1 reason our motors will not be allowed is because sensorless brushless is much more difficult and expensive to manufacture, and those other companies either don't want to invest the money, or don't have the know-how to do a sensorless system. It's easier to write the competition out of the rules.
I can not agree more with you.
I have been telling this here at local forums for 2 years already.
But now Joe I would to ask you something.
Let me tell you first that I use MM with 6900 motor in local races and have to use a diferent motor at nacional events. Started with MM esc but soon had to move to one that allow sensors to use with the Legal motor, because the startup sometimes is not perfect with MM esc. and that motor.
Let me tell you I am not a Top driver too, I stay in the middle of list.
But my questions is. Here in local forums some of the top drivers say to me they have tryed Mambas but they found out the system is very inefficient, develops a lot of heat, burn the motors and they have not runtime with them. They mention this in comparison with novak, lrp and speedpassion 4,5T brushless systems
I have not this ideia about Mamba system. Is there any good special reason for this or just those systems are more efficient?
