i just took my warhead apart and the engine bulkhead broke where the 2 fuel tank screws go through so i think the motor probably moved and took out my spur gear....i took the clutch apart while i have the engine out for the 3rd time and it's just wore down to the spring....it.s only bin runnin since last thursday night and have run about 5 tanks through... broke parts so far- recoil, rear driver side bulk head,front skid plate, radio tray,radio tray lid,engine bulkhead,spur gear, clutch shoes[].... i'm still havin fun with it though but it gets frustrating... i'm just gonna order this stuff and in a couple months i'll send all my busted parts in for exchange....hopefully i won't have to send the whole truck in haha....
