help with engine choices for my X1crt
 

Hello.
I need some expert knowledge!
I need new engine for my Brushless X1Crt,
I am unsure about which of the 2 motors I have to choose!
What I can read me to the medusa is a good engine, so which of these should I choose?
Medusa Products Afterburner V2 MR036-70-2000V2-5 (5mm shaft, 115A, 2000kv)
Medusa Products Afterburner V2 80mm MR036-80-2200V2-5 (5mm shaft, 117a, 2200kv)
ESC is a Ezrun 150A
Sincerely, Kenneth

36-80-2200 would be my choice between those two.

I am assuming you're going to be running 4S?

yes, as a minimum
Perhaps 5s if it is to have a little extra on the track

The 36-80-2200 would be my choice then. I'd probably start with gearing at 14:62 and go from there. That should put you around 38-40mph on 4S. If you go to 5S, you may want to drop back to 13:62, which is also a very good gearing for 4S too. I run 13:62 on my CRT with a Neu 1515/1Y (2200kv).

okay, thank you
Have 14T pinion and (16-18) but then I do not need them.
