Default No more stripping frontbelts.

Some may have experienced to many problems with stripping belts as I did.

Last weeks I am building up a new car and I want to share my solution on this problem what I have built on previous cars as well.

A view on the short middle shaft of a MRX4 and front belt.



On the radio tray I placed a holder with a belt tensioner. It is not realy tensioning the belt but it keeps the belt around the small 16t pulley so the belt will keep grip on more teeth of the pulley as the drawing shows in the upper left corner. Believe me, with this you can do ages with a belt.

The problem is that the belt will rubb the servosaver. You can grind away some material from the saver but I did lower it by some mm.



I just did take off some material from the underside of the saver and moved the bearing inside the saver. On top there is a spacer.

Now I am busy showing my car, my hom made exhaust cooler:





And the car



Wth Savox servo's and all silicone wirering.

For those with Kyosho's:

We have been running front tensioners for over 5 years. They do help reduce stripping belts. Bumpy, high speed tracks are the worst - they do a ton of damage

Hey Rich, that's a real nice piece. I was told years ago they were going to make one for the Mugen but they never have

Easy, now.

Kyosho is the brand we race - hence, what we develop. When we ran Picco's with Ron Paris - we did Picco stuff. It's not about likes or dislikes. We sell what we race.

I have no interest in "who is friends with whom" We all do this as our hobby - quite frankly, I love RC cars - and to that end - anyone who races them is my friend....

Including Traxxas - because, I love my Slash, baby!!!

Default Tensioner

I was thinking of making one but what about a bottom mounted one? Not much room but I'm going to do it. I'll see how it goes.

Late,
You are better off doing it on the top side. When the car is Under a load ,the belt is tightest on the bottom side,, So your Slack will stay snug on the top side..with it mounted like he has it.
Hope this helps.
