Most top end ESC's do not have any motor limit, so that is that 1st step in your choice.
Below are top class ESC's:
. LRP SXX TC Spec
. Speed Passion GT v2 (this is on sale now, so a very good deal)
. Tekin RS Pro
Some local/ very good popular brands:
. Team Wave RB50
. HobbyWing 120A v2
As for motors: SP, Novak and LRP are very good choices.
Some c-hing may say its better to match the ESC + motor brands to get the most out of them... so LRP or SP are your choice. good luck!
thanks! this is very handy information, thanks! I will mark it down and check out the spec and price. I think about the electonics stuff....better get new set right?
I agree. Buy an no-limit esc and get slower motors first. Then play with gearing and settings. Then work your way up to faster motors when you have full control of your car.
If you want expandability, consider an esc with 3S lipo support. That way, you can try the power of 3s + 5.5r. This will be faster than 2s + 2.5r.
