A healthy mixture of Unlimited Engineering (their stage 3 chassis kit and their stage 3 ext suspension kit) and Hardcore Racing pieces parts (purple in color, bulkheads, bulkhead braces, skid plates (Ti), tranny kit, diff casings, etc.), Progressive Suspension's shock kit with piggy back reservoirs (will probably stick with Trinity Springs), RRP spurs, Racer's Edge Clutch, Fantom .21 motor, whoever makes Ti axles for all areas (center, front and rear...a set of Ti CVDs would be nice)...I'm sure there are a few things I'm missing, but that's the list of the big stuff for now...Oh, yeah...Lynx 3D radio, HiTec Digital servos for all, 1100Nimh hump pack, probably use plastic cases where applicable for receiver box and battery pack if needed (then again I may go Al there also). I may look into mounting two fuel tanks. The header and pipe are still a question mark due to my desire for the Fantom motor and there being a lack of information on its particulars (exhaust set up...rear or side...I suspect rear). Also looking for the best set of gears...tranny and diffs.
