Nah Swamp3r, we all have to start somewhere.
FIRSTLY you NEVER start your Nitro Truck indoors, exhaust gasses = NOT GOOD.
Yes you do need the glow plug heater to start your engine EVERYTIME because even if it's hot, it dosent neccessarily mean that your glow plug is ignited.
And as 2D stated, truggies dont have reverse. 2 speed options are avaliable, but I think you have to rip out your center diff, and IMO a center diff is one of the most important things on any truggy.
And welcome to the RC World
