1920 overworked?

[Finnster]

One of those batteries is as big as I would go into a CRT.5. You don't want it to be too heavy or it will drive like crap and break easily. 4S 6000mah is bigger than some put in 1/8th scales which are twice the size as the .5.

I have a 1920/10 (3135kv) on mine on 3S and I love it. Small but powerful and stays cool no matter the gearing. I've ran mashers on it geared 14/46 (at least equiv to a 18/46 gearing on stock tires) and it ran cool. On 13/46 on mashers it hit a top spd of 46 on radar. I'm able to backflip the truck pretty easily if I hammer it at spd, but not so much TQ to make it too easy and undriveable.

The only thing is I am drawing a good deal of amps. ~75A on the higher gearing. The 7 turn will draw more if geared aggressively. Hopefully you have a hi-amp version. If not I would watch the gearing or considering rewiring to delta to give ~2800 kv and think about smaller batts on 4S or even 3S for very track worthy spds.
