Can't say that I have seen them. Mine is fairly new, so I haven't had problems with the belt, but I did with the diff casing. A piece of glass messed it up pretty bad, so I'm replacing it with the aluminum diff case. I hope I made the right decision...

I havent actually performed such stress analyses, its just my intuition. Take it for whats its worth .. I'm not a mechanical engineer... I work with electrons only

Alternate - from the botton portion of the "belt loop", lift up on the belt. See if the bottom can touch the upper belt of the loop. Mine comes about 1/8" from the two sides from touching. Did that make any sense?

i did not understand that...how bout on the slot where u can slide the belt tensioner....where should it be

The belt doesn't need to be very tight. As long as it doesn't slip or fall off you are fine. Just remember, if you tighten it too much, you increase the friction and drag so you car won't be as fast.

round one victory
Hi Guys, Strike up another victory for the R40!!!
we had our first race meeting for this season last night which i ran the R40 for the first time. 3 first places and 1 third gave me the overall victory for the night. Thanks for all the good advice on the forum, next thing to try will be a locked front diff.
Can any tell me what is the best stuff to fill the standard diff with to lock it up, i have heard putty is good?
If the locked diff suits the track then i will buy a solid front axel.

serpent cleaning gum works, so does modeling clay. Its a hassle getting it back out though. You might be better off getting the solid axle. I think it only $13 or so for the aluminum plug that replaces the gears.

Thanks, i'll try the clay and see how it goes.
