Hi, im relatively new to mini 4wd. Used to love it as a kid and now I'm trying to make a more competitive comeback.

I just went to the HK race the other day and realized how slow I was compared to everyone.

I have two questions though.

How do you reduce friction when going through turns, and

How do I make my motor churn out more power because I was using the same motor as everyone else and my car was at least 5 seconds slower than everyone.

Here is my car:

take out that sliding bumper at the rear and you will be faster than before

Thanks so much David! I'm going to try that right now.

I thought using the sliding bumper would help me be faster on turns.

I was also wondering why my cars power didn't seem as fast compared to everyone elses. 5 seconds is a lot of time even thought I'm still relatively new. And I was 10 seconds off from the winner too. Average was about 22 seconds and I had 27.

Would it be the battery?

can't sleep... checking some motor data...

for those powerful motor... normally 3V under no load will consume 0.7~0.8(10A)...

thus, provide high speed and high toque...

but ensure there is no other load that cause power consume when you test...also... no other lube for less friction...
