Belt stretch is rare but possible. More likely front to rear chassis flex allowing for slack in the belt. Check your chassis brace and all the screws that hold the front and rear sections on. If you don't have a chassis brace, get one.

Agreed on the 4600. I have only run this truck on outdoor dirt and pavement tracks so I will definitely be taking my 3800 along to see which does best for me in practice. Thanks for the confirmation on the Ions. Should be a good laugh for the locals ... me racing indoor clay for the first time!

Did this just start happening or has it been from the get go? If it just started how long have you been running, what condition is the pulley and belt and what are your tensioners set at?

Does anyone else make ball cups for the sc104x4?
Mine are starting to get a little bit of play in them.

for the belt falling off the pulley issue, from what I recall one cause was if you assembled the pulley wrong. Look at the manual again and confirm you have it assembled correctly as I believe you can assemble it wrong and the belt can eventually slide off.

Yes, it does matter if you are running without the front cover. I had the same problem when I tried to run without the cover, and found that the plastic pulley mount can flex too much without the cover on. One of the mods on this thread shows a front pulley mount fashioned out of carbon fiber.

Reedy just announced a Mach 2 4 pole in 4300 & 4800kv for SC 4x4s!

pretty cool.

Interesting to see timing on the motor can as well.

Nice find, did you see a price? I couldn't find one on that page. I am looking for a motor and was considering the HW 4000kv till you posted that one =)

tower has them listed, here is one:

initial price of $173.99 . I am assuming it will go down to about the same price as a Tekin 4 pole, maybe $10 more but not sure.

Thanks Cain.

no prob. If you get it let us know how it goes. It looks to be ROAR legal so thats a plus if you are required to have that as the Hobbywing one I don't think is.

I was wondering about that actually, I have seen a lot of people rave about the HW motor, so I just assumed it was ROAR legal, so its handy to know it isn't.

yeah, its like a 545 can from what I recall. Great motor for the price, especially if you can run it at the tracks you race at.

I recently purchased a new sc10 4x4 limited monster energy addition. First off i love this truck and its my first SC truck and first associated as well. When running on my friends back yard track it ran great but my only problem was horrible traction. If I gave just a touch too much throttle it would do donuts in the turns. Any suggestions or help in fixing my traction problem? Thanks in advance

I purchased a Futaba pl3 radio system. I have it paired to the stock sc1200 esc but cannot get it to go into calibration mode??? Need to set lipo mode. Reverse is also faster than forward.

Help me please.
