T4 rs rtr
 

I,ve decided to buy a t4 rs rtr and put a mamba max 5700kv motor in it:004: .
I,d like to know how long runtimes i coud get with a 6cell gp 3300mah pack ?
and how much longer with a IB4200 mah ? or coud i go for a maxaps 2-3s 8000mha lipo pack ?

I would go for the Max Amps 3S 8000mah pack with the slowest motor they have (4600 I believe).

hm why the 4600kv and not the 5700kv ?

A faster motor will go faster to be sure, but runtimes won't be as good and you have to make sure your batteries can handle the current a high kv/low turn motor will draw.

Besides, the 5700 will be in excess of 60k rpms. Aim for 35 to 40k.

You can aim for 50k rpm for the mamba max motors. Castle says the 5700 can handle 3s, but it probably wouldn't be a good idea if your worried about overheating.
