rc cars mamba brushless in a t4 or touring car radio controlled?
Written by admin on April 6, 2009 – 1:06 pm -
i have a 7700 mamba max thinking about using ib4200 or ep4200 anyway, how much differance would there be if it went in a 2wd t4 stadium truck, or a carbon fibre touring car in mph please, thanks
Using the 7700 in either will give you kickass acceleration… expect the truck to be slower than the touring car – but that all depends on the gearing & tyres used (plus weight / drag co-efficient)… expect 50+mph in both

I have a AE TC4 with brushless mamba 5700 and max amps lipo, with highest safe gearing I reached a top speed on 56mph.
Using the same setup testing in my Traxxas Stampede and high gearing the top speed of 45mph but got very hot and began cogging at the end of the runs.
My team Losi XXXT on the other hand which is in very close relation to the T4 produced tons of torque with even the 5700kv and did wheelies no problem with a top speed of 46mph.
Whatever vehicle you choose to put mamba max into expect to gain at least another 15mph more than what you are using now. Understand that weight also plays a factor, The lower the KV of a brushless motor the more torque you will get versus speed, and higher the kv is vice versa. For larger trucks and heavier vehicles it is much better to purhase the lower kv motor with more torque than speed and use larger voltage batteries so you do not place excessive stress on the motor.
