Sell the esc for as cheap as possible

I'm sure you will work out a competitive price , when you do PM thanks as i will use it in my 2s speed record pan car .

Question on the speed car , do you think heavier lipos are better or lighter ones . I am looking at either the SMC 28c 4000mah or 5000mah packs , but i am thinking the heavier battery would help keep the car on the ground .

Any other battery you can recommend that will handle the amps drawn with the Vortex 2.5t motor and gearing you recommended . I have chosen the SMC packs as i know they will fit in the car i am buying and they are top quality cells .

2.00 with a bike is impressive , good luck on the challenge .
