Maybe you are right about the micro motors since during normal speed (I guess the micro motor can take the heat at normal speed) the problem doesn't really happen.
My Heng Long tank was fine when I run using normal speed until Istart using double speed for some time and it veer to one side too.

Regardless though Ihope VSTANKcan give my distributor a good answer/solution so Ican get my desired M1A2 abrams tank.
Though the distributor is willing to give a full refund, Irather land my hand on the tank of my dream.
