IDK if your familiar with ACE from NYC (or Draven 3907 as hes called on youtube) but he has one of the fastest rustlers around. I've been doing a less extreme version of what he is doing but I have a question.....He states in one o fhis videos he can do speed runs with the stock velenion system on 76/35 gearing. I current am trying to run that same gearing and even bought a Castle 3800kv 4-pole motor to help push the lower gear ratio. Mine cogs alot. Now I did buy my 4 pole Castle used off of ebay but it wourks great when I'm running 76/28 gearing.....So can any one take a stab at why the Ace guy claims hes running 76/35 gear on the stock motor yet I can't on a Castle 4-pole?
