Motor/ESC...
 

Hello, i just got B4.1 WC and already built her up. I already have SAVOX servo 1257TG and now thinking of the motor/esc. I have a spare 6.5T SP motor and wondering if its too powerful for the 2wd? Any opinion will be appreciated.

Also i need some info on pinion use on my B44.2 buggy. She's using SP Reventon Pro 1.1 with 7.5T motor. Spur is 81T. What size pinion should i start with? Thanks in advance.

Cheers...:)

how big is the track you'll be racing on?

You might be better putting the 7.5 in your 2wd and the 6.5 in your 4wd...at least you wouldn't need to buy a new motor this way?

My track is small/medium size. Actually my current setup on my B44.2 is the 6.5T but its too strong for my track and i have to bring down my EP to -25% and also recently my ESC is not working therefore i bought a new combo 7.5T. I will be mostly race on my B44.2 and not my B4.1 and will be putting the new combo to my B44.2.

23 or 24, 23 or lower and it gets a little warmer.
24 is good but a 26 with be better for you if you want it smoother(slower)
I put a 6.5 in mine for me its better than a 7.5 but if its a smaller track i imagine your on the brake a lot so if heat is an issue then up the pinion.
Although a sp 1.1 i think runs a little cooler than a rev v3, i am thinking about getting the larger capacitor bank for mine.
