Er... nobody's asked the real question:
Are these 1400mAh Nicads SubC's our AA or AAA's?
If they are SubC's, well, obviously this is nonsense to still race 1400Scr's and have a T35, but anyways... Les is right ('sup, Les?)
If these are Tx/Rx batts, do not go higher than 0.5A.
No matter what, if you can afford a T35, get a real RC car
