Thank you, I will be putting the Neu 1512 df in the truck and I was under the impression that this motor was somewhat high in the rpm range for the E-revo and since I was going to be running the MM until the MMM comes out, I opted for 14 tooth with the 61/62 on the spur. Will this make the truck a wheely monster? I would rather see 40+ mph than wheel stands.If you think I can safely turn 18 to 21t I'll pick some up.
