I'm running a sct410.3, with the max10sct and the 4600kv on 2s, with a 17t pinion. No racing, just a "basher". It runs awesome, more than fast enough, nothing overheats ever. Awesome truck. Your plan is what I wish I had done, but I had a bunch of good 2s battery so went with the 4600. Get a variety of pinion gears and test and tune till you and the truck are both happy.
