hey mojoe try getting mugen or kyosho parts with a reasonable budget and a hobby shop that doesn't carry those cadillac parts.... sometimes racers great creative... and make their own mods and own setups, instead of photocopied results and suggestions from car action....the hellfire owners if they can be patient will learn alot about how race vehicles work and how to tune them, many of them were bashers first, and they figure that the hellfire would be tough as nails like the savage, well some parts are and some very weak, but it does have one of the better stock engines that should last quite a few gallons...we have guys at our track that have less than 2 gallons replacing that hand grenade of engine made by ofna( rtr crt .28) this center diff racing world is new to alot of us and with time i will be a good enough driver to warrant a $1500 truggy/ engine combo...but for now i will take my mild mod hellfire( carbon top plate, werks clutch, and nova 528) and practice my skills driving and save the bashing for you "pros" with unlimited budget. peace out[8D]
