Default Tuning electric motors

Hi,

this has probably been discussed a million times, but here goes...

well, what tips are there to tune an electric motor?

Currently, I have a 17x2 Nosram Vision, and on the dyno (Robitronic Pro Master) it gives me 120W... good? bad? Tips welcome...

TIA

i have a problem with runtime (not sure if its motor or my gearing).
well i run 1/12 mod with a orion V2 8x2 and i cant make 8mins.
My gearing is 5.2 and a charge at 3.5/4amps and my timing is 12 deg.
what should i change to get runtime?

Depending on layout of track, you will have issues trying to get a 8x2 to make 8 minutes. It isn't like sedan which is 5 minutes. Charging at 3.5 -4amps isn't good either. I know you are trying to make runtime, but charging that way isn't the way to go. Most guys are pushing with a 9t, and sometimes its necessary for a receiver pack that low especially if you make any mistakes and aren't really goodd at rolling the throttle. To be safe, go with a good 10x2 or 10x1. Also, a lot depends on what batteries you are running. With the new IB3800s, charged at 5-6amps, .5 cutoff per cell or 125 degrees for pack, you will be right on the border. Your timing is about right on the motor though.

I think you are better off with 8x1 for acceleration or 8x2 for little bit more top speed
