Status: offline 		I found the answer to the pulsing brakes and ut being applied on throttle while driving. The screws that attach the brake cams to diff housing was way too tight. i assume that it should be as tight as the previous brakes. The buggy now rolls free and that is why the clutch was overheating(323 degrees with temp gun) because of extra drag in driveline. It now rolls free and holds well.

Status: offline 		I had a chance to actually try it out and got the clutch temp to 230 which seems about right, and I also installed the mugen clutch shoes with the gray Ofna springs and it seems to be stiffer than stock, but seems o.k. . This seems to be a really tuff buggy, but i have a little chassis flex. is it common with most buggies? It flexes at the center diff housing. Stiffeners were tight and in place. It takes a bit of force to make it flex, so it may be acceptable.

Status: offline 		If you are just going to be bashing get the RTR, the .26 motor really screams once you get it dialed in. If you plan on doing some racing you'd be better off getting the Pro ARR with the .21 motor. I bought a RTR and I've already started upgrading with pro parts. If i knew then what I do now i would have bought the pro from the start and just picked up a nice JR XS3 radio system off ebay.

e-clips are no problem on the mayhem
better choose a Pro kit if you want to upgrade afterwards

pro does have mid driveshafts cvd not dogbones
4 mm shocktowers (but there are new 5mm ones now available)
and other items better finished
and motor sits lower but with starterbox

Status: offline 		leejax - I've noticed this also. I causes the clutch bell gear to move back and forth relative to the spur gear. When I put a steel straight edge along the bottom of the chassis, there's about a 3/32" drop from one end to the other. I've also had to elongate the rear body mounting hole forward about an 1/8" because the car has apparently "bowed up" enough to shorten the relative distance between the body mounting studs. I don't do jumps either!? Been trying to see how I could fabricate a stiffener to basically go from front to rear and attach to the existing stiffener mounts. Anyone ever heard of such a thing?

Status: offline 		ok-- i have a couple of questions. i was playing with my mayhem yesterday on asphalt and it would launch hard and spin the tires on the pavement and leave black marks. the left front axle broke where the pin holds the axle to the drive cup. the drive cup itself is what broke. and it started making a high pitched noise and acted like the clutch was slipping and then it quit moving altogether. is the axle breaking being experienced by anyone else and horizon already has me a set of clutch shoes in the mail.

Status: offline 		yes I have had an axle break. Mine snapped off clean at the hub. I replaced it with a Hot bodies unit because that was all that was available! The high pitched noise is the diffs. What happens is these diffs send power to the side that has the least resistance. so when that front driveshaft broke it caused the engine to spead up cause only that side was trying to pull! I don't know why it stopped going all together cause it should still move unless you fryed a bearing in the clutch bell at the same time.

Status: offline 		I also broke a front CVD on my RTR when I first got it.. granted it was from it cartwheeling across the parking lot after catching 15 feet of air anyway, i bought a new one and got a spare just in case it happens again.

Status: offline 		For those of you with the RTR version. Check your diffs! I tore my sons car down for the first time this weekend. The front and rear diffs were empty.. bone dry. My neighbors RTR was also dry in the rear diff.

Status: offline 		Giles or anyone else,

What diff fluids are you running with your large carb intake. I changed to the large intake yesterday and I believe I may have too much power going to the rear. I'm running 5-7-1. Of course, it sounds like I need to check the front and rear anyway. I've never had them open.

Status: offline 		OK after 1 week of tearing the hell out of my newly purchased rtr the only parts i have damaged was 2 of the 3 plastic parts on the whole thing.
1. on my 1st jump i managed to screw it up and landed spoiler 1st into the ground(dont ask how) so i bent one side of the spoiler mount bought the whole mount kit so now i have spares (5.99) for the kit.
2. Ran it head on full throttle into a raised portion of concrete...broke the battery tray in the reciever box...called hobby shop and they said how did you break that thing? i had no answer but i replaced it with rechargeable packs...better anyway
