Ching,i play rc car more than 25 yr,never burn esc,i hv lrp speed passion tekin novak hobby wing at home still now.... for u reference, M car in TC, 4000kv, lipo , Final gear 5.735
fair and honest say, any electric stuff may hv problem,bad luck lor,charge me $320 means what, pay and buy a new one lor,$320 is not a issue but just means the factory doesnt take care the customer,in another way say, the esc is not safe,if i didnt open the shell, the esc burnt the lipo, then explose....
i burned my esc too before, just turned it on and then it burned, it was a viper... now stick with futaba, novak, and tamiya... seems better. i dun think the gear ratio has any effects on esc if you have not even started the car and run; if you run and burn, gear ratio may be an issue.
i suppose want to hide this fact, change a new one or fix, i bad luck only, but 代理人同我講 factory say will not believe this one case will affect their business....this is totally unresponese word...so i decide not to hide this truth
