My buddy and i bought the MGT at the same time we broke the motors in as the book said and it ran great. for a week i broke mine in with blue thunder fuel he did his with o'donnels, when we ran out i bought us both some traxxes fuel. they ran great for half the gallon then one day they wouldnt shift into 2nd gear but it would shift in reverse. but it ran balls out when it was about to run out of fuel. so we changed fuel again we both went back to o'donnels they ran great for a day then same thing happened so finally i went back to blue thunder and the same thing we have been threw dozens of glow plugs we tuned to no end and we even changed the fuel line thinking there might be a leak. im getting really mad i didnt shell out $600 to look at it on my shop table

so long story short its hard to start wont shift into 2nd runs like its bogging sometimes then when its just about to run out of fuel it runs great for 5 seconds has anyone else had this problem please help
