Need advice on a setup?
 

I have an E-Maxx with all appropriate drive train upgrades. Mostly RPM plastic to keep my weight down. I purchased a Neu/1y/1f motor and tried to use it to with my existing MM and 14 cells. The voltage was too high. I do have two TrackPower 2s1p packs that I have not opened yet, but could probably use with the MM. I plan on purchasing either a MGM 224/18 or a 160/18 because I can not tolerate the cogging.

My question is should I open and use the TrackPower batteries or because the MGM can handle more get a 6s or 18 cell batteries? My current gearing is 52/17. I wanted at about 40mph for bashing. The bigger batts according to Brians speed calculator put me abouve 50mph. If I went with the bigger batts I could get a heavier extended chassis for better control or smaller batts and stay plastic?

The 1515/1Y on 6S is going to be too much in my opinion. More voltage is usually a better thing, but I'd get a lower kv motor to run on that much voltage. The 1515/1Y on 4S is about perfect in a truck. On 5S it gets to be a bit too much. On 6S I think that it would be way beyond practical.

My everyday setup in my 8ight T is a 1515/2.5d on 5S. Geared 18/48 with Proline Badlands MT tires, I clocked it at 50 mph. It's a lot of power and speed for a truck. For 6S, I'd get a motor with an even lower kv rating.

Since you already have the 1Y, I'd just run the 4S setup and maybe get a 5S pack later for occassional insanity. The 1Y is a good motor and the Compro stays very cool.

Thanks. That is they way I'll go. I just charged my batts and ordered the 160/18 from Mike. in 2 days they'll be no cogging.

:surprised: After reading your post I thought if i can get 6s why not. Well, 4s alone is insanely fast. 6s in a an E-Maxx is just stupid for a basher. I may as you suggested try some speed runs with a 5s. thanks for helping this noob out.

Yes, good choice on the MGM controller, they are great esc's!


6s lipo will be 2x as powerful as 4s lipo given the same motor, your rpm will go up 50%, and torque curve 50%.... 2x as powerful, in other words yes, stupid-crazy-insane-retarded fast! :surprised:
