Medusa Research
 

hi what Medusa Research motor can go in a emaxx i want atlest 45mph out of it more if possible also what gearing

thanks

I would say that a 70mm would be the best bet for an emaxx. Something around 2000-2200kv. Not sure on the gearing, use the gear calc by briang.

castil 2200kv or MedUsa 2200kv 70mm

I would go with the Castle motor myself.

just got my self a Castle 2200kv what gering do i need

22 to 25 pion!!

I have medusa 70-2300. I used 22/62 for 40-42 mph and 24/58 gor 48-50 mph
temp 120-150f
2x2s 5200mah
mmm

Pete- Use the calculator, it is your friend & greatest tool known to man & noob-kind:

Enter the values according to your desired setup; model, voltage, motor kv etc, and it will spit out results based on what you input, its very simple to use.

For example, you want ~45mph on the emaxx 3905 (?) with 2x2s lipo(?), in which case:

That would be a solid and sensible setup, with room for adjustment.

Choosing decent lipos and tweaking the esc settings will make all the difference for good temps, long runtime and best performance.
