Hello I am David,
I have an XB4'16 with LRP X20 4.5T engine and I have problems with the transmission.
The satellites of the differential and the conic pairs break.
Use minipin 2 yellow tires and run on high traction carpet.
Both composite and steel gears do not hold. Three runways and a machine to be dismantled. I completely repaired the machine and made a substantial change to the clutch as it did not work with the three pads.
Tonight I'm going to try and then let you know and if you have any advice I'm grateful to you ..

After the various tests on the track I found that the clutch does not work.
Do you have advice to give me?

I can run all winter on one set of gears without any problem.
I use everything same like in kit and with loser slipper.
Did you build everything correct?

ciao Martin

Did you build everything correct?

I used the model used by a friend, and it was completely removed and reassembled by me with new spare parts following the entire manual so I would say that I own a new model.
I know the 4.5T engine is a beast, and I was sure that before or after the transmission was given ... in fact, even on Thursday night at the end of the evening, the rear satellites are dusty because the clutch works very little.
From what I think I need to redesign the drive pushed by the spring and remove the third pad and the 1mm intermediate disc
