RE: Sportwerks Mayhem ST
Finally got here yesterday a month later than expected but it was worth it. Best $130 I ever spent. Box had mayhem st w dx2 duratrax dual battery charger 2 3800mah batteries for roto starter complete set of stainless screws NIP OFNA tool kit NIP shock springs glo plug wheel nuts axle pins fuel tubing rx pack various fluids and some other stuff that I am forgetting. Truck had sportwerks aluminum arms and upgraded shock towers HT pipe wing kit harder springs. I was in over all great condition not stored correctly but engine started right up. Any one know how to get dried fuel off? If it gets above 10 degrees today I will go out and break it.

I know that this truggy is old news and that no one plays with them any more but I still have a few questions about my daily basher. Anybody know a body that will fit on the regular length chassis with out to many mods the stock body is too big and bulky not to mention kinda ugly.

RE: Sportwerks Mayhem ST
I have a Mayhem ST with pretty low hours. The first part I had broke was the clutch. I repaired and after it sat for awhile, now the drill starter will only periodically crank the piston. The hex doesn't appear stripped and it is spinning. Isnt this a hex bolt linked directly to the piston? How could it spin w/o turning over the engine. Any help would be greatly appreciated. I finally got the time to bash and never got warmed up. Plus my truck is still full of fuel. Also, has anyone had to beef up the steering servos, they seem a little undersized?

RE: Sportwerks Mayhem ST
If you have the RTR, then yes, the steering servo is crap. I run a Hitec 5955. I've also used a JR 9000T, both are great servos and well worth the money. Use the stock 590 steering servo for throttle / brakes.
As for your starting problem, the sharter shaft shaft turns another shaft, which turns a one way bearing, which then turns the crankshaft. So no, it's not connected straight to the piston. Your problem is that the one way bearing is dirty or worn. You'll likely want to remove the engine from the chassis, and then remove the four screws holding the roto-start backplate on. You may have to remove the engine backplate as well (another four screws). With my pull-start, the one way bearing was inside the engine backplate. I think it's the same for the roto start.
Once you have the bearing out, blast it with some nitro cleaner or carb cleaner. Also clean the shaft which goes into the one-way bearing. Then, reinstall and try again. If it still slips, it needs to be replaced.

RE: Sportwerks Mayhem ST
thinking about picking on of these up.
Where is a good place to get parts? I see Amain has some parts but i do not see diff parts there for the MT. Are the buggy gears the same parts?
thanks

RE: Sportwerks Mayhem ST
I buy almost all of my parts from amain.
The ring and pinion gears are different for the ST (45/11). The rest of the differential is identical to both the Mayhem and Turmoil buggies (cup, spider gears, cross shafts, pins, outdrives, etc.). In fact, the ST shares most of its parts with the buggy. Basically, if you don't see it [link=http://www.amainhobbies.com/index.php/cPath/1_25_287]here[/link], then it's listed under the buggy.
What I did was purchase two complete mayhem buggy differentials from one of the eBay chop shops. Got them for much cheaper than the parts cost seperately. I then sold the ring / pinion gears to a local racer for less than they cost in stores. That paid for both differentials, and then some. Walla, free spare parts!

RE: Sportwerks Mayhem ST
I know I'm digging up an old thread, but I'm looking for an extended chassis for my Mayhem ST. From what I've read, the Turmoil pro buggy chassis is supposed to be longer than the mayhem st chassis, but when I compare pics it doesnt look like its longer at all.
I just want to run a standard truggy body on it. Anyone know about this chassis?

Hi all I never posted anything on here before but I have 2 MST and never had a problem out of them but to answer your question I crashed one of them and and couldn't find a MST chassis so I got the turmoil and all of my MST parts fit just find. But you will save your self alot of trouble if you just convert your MST to a brushless one. That I call the MSTe that is much fast and more powerful and a blast to run. Just a thought !!!!
