MGM 4032-3s for HV truggy?

[othello]

I have gathered several Eagletree log files with my HV Truggy running a 1100kv Neu 1515 with a Jazz 55-10-32 Esc powered by 9s1p - 10s1p A123 (27-30V average). Average amp draw hovers between 15-22A (400-600W). Peak amps might be as low as 50-65A but could also reach 100-120A. Really depends on how much grip you have, your driving style, tires mounted, battery powering your setup, gearing. My Esc is underrated with 55A cont and 65A burst since it also provides peak Amps between 100-120A. I had to mount a heatsink to keep it cool. Since then i had no heat issues.

With a low gearing around 36mph you might see Amp Peaks around 50-65A. 10s1p A123 can be compared with 8s lipo. 9s1p A123 with 7s lipo. From a continouus point of view your ESC is up to the job. 50A burst is on the low side and would suffice for a buggy. For a truggy it might not suffice.

Thanks guys. If it helps, I'll be running badlands on street and hard dirt, with an occasional gravel run.

Badlands are relative heavy tires compared to race tires (Crimefighter, Bowties lpr). They require more power while accelerating (more rotating mass) and to maintain top speed. You could contact MGM if they would recommend this ESC for your project. I would say they will tell you that you require at least an MGM 9032.

Yeah, I bet they would. This project won't be started for a while, so I can wait.
