My mm is getting hot....I would like an opinion or 2

[magman]

It has been thermal-ing after only 10 min....however, I am running in very soft sand w/paddle tires on rear and 2.2 Gladiators on the front.

start power.....med.
punch control..10%
timing............ 2
lvc..................3.2 on a 3s batt.

mm esc w/ccbec
motor 1509 TeknoNeu 3300kv

stock spur w/a 17 pinion

I am not getting excessive wheel spin due to the paddles on the rear...so I am thinking it is a gearing issue..opinions?
