Default Inferno 777 Clutch Problem, weak material

Does anyone knows a after-market or better clutch than Kyosho?

I broke 2 springs in less than 30min of running.
also noticed that aluminum shoes has short life, because it melt and then the spring scratch in Clutch bell. I tested the Carbon shoe of Kyosho and the problems is the same.

I have never had a problem with the kyosho clutch. Do you have the little washers underneath the shoes?

I've not had problems with the kyosho aluminium clutch shoes and springs too. I've run 2 x 40min mains without any issues. I put a shim in each shoe.

I have broken one spring, but it was an old used up one.
I have not had any issues with the aluminum shoes or carbon shoes.
I run aluminum now mostly with 1.1 all around or two 1.1 and one .95
After every race weekend though i pull my clutchbell off and sand down
the inside and smooth out my shoes also. I replace springs when the motor begins to get abit weak with snap out of tight turns etc...

poor clutch maintenance leads to improperly working clutch ! i have had one spring break in 6 yrs. of running kyosho , as far as the shoes go the newer hd 7075 shoes are a touch longer lasting . use two of the .2mm shims under the clutch shoes with a touch of synthetic oil rubbed on them . only use original kyosho clutch springs 1.0mm springs is a pretty good setup for most . make sure to change bearings at very first sign of crunchiness , for longer lasting bearings heat bearing with your heat gun for about 1 min. then drop one to two drops of a full synthetc gear oil viscosity lube. properly shimming clutch bell so it doesn't rub on flywheel and also isn't too far from the clutch bell leaving a total of .2mm of play in clutch bell .
all these things will help you out ,

I didn't want to start a new thread for this so this looks like a good spot to ask. I'm eating clutch bearings like potato chips. I can't go a full weekend without chewing up a bearing. I'm not sure if it not shimmed properly, changed the shims a few times to check and still eating them. Any Ideas??

Thanks

A full weekend on a clutch? That is pretty good for a set of bearings. Just depends on how much you run. You can probably get a gallon on a set of bearings if you clean them once.

On the original thread topic, that is a very unusual claim you are making. Kyosho has had the most succesful clutch set-up in the hobby for the past decade. In EVERY case I can think of, when someone asked me to help them with "Kyosho" clutch problems, there was some other third party part in the equation, like a clutch bell, shoes, flywheel, etc. Clutch parts are not interchangeable. Just a couple thousandths different measrement on any single part can cause the problems you are describing.

If you are using a Kyosho clutch, ALL the parts must be Kyosho. There's just too much variance on third party parts.
