You said you didnt want to race, yet you have gone for the high gearing, and you fitted Stampede tyres, which have a much greater rolling radius, which gears it up even more!
The stock gearing of 25/83 with a 3 cell will knock over most basher rigs anyway, so why change it?
Just drop the pinion size right down to 17 as suggested or to a 20 max.
With the VXL esc always make sure you run a fan, (they are a genuine 200amp esc) and always check the motor temp.
They are an underated motor kv wise but they do suffer from heat exhaustion!

P.S The 13/84 and the 17/86 will prove to be quite slow, however if you want to keep those wheels on its worth a shot....
