Big or Small.. I will love them all.. I went with a Max 5, as the Max 4 was a bit over my head for cost.. In Canada it is almost $1000 CAD for that ESC! Regardless, this is a massive upgrade over what I had. Now, on to the mechanical size of things.. all that work only to get the electronic jitters in the end.. I have to investigate that.. I will replace the receiver and transmitter.. although I am not sure that's the issue. I have checked my wiring, all of my motor wires are correct. Firmware i
