Assistance needed from LST owners....

[Desert Rc]

wondering if you could help me trouble shoot a issue with my new converted xxl. I put it all together with the TDR single speed hub and slipper pads. Upon my first run today I drove about 60 feet and the drive train disengages. By rolling the rig around it will re-engage. I know that the slipper has a pin in the back of the assembly that transfers the power to the drive. Now even tho there is a ever small amount of slop in the tranny shaft that holds the slipper plates I am wondering if somehow the pin is slipping. I doubt this as I have taken apart and redone it.

I have taken apart the slipper and reassembled 3 times all seems tight, then same scenario...It runs about 50 fooot and then just the slipper and pinion/spur spin and noting engages in the drive-train. I am a bit puzzled. The tranny has never been apart as this was a NIB rtr. Before a full fledged teardown I was wondering if you have an idea what I may be going thru.

I have heard of guys do the forward only tranny conversions on their lst2 from aftershock tranny, but I dunno what up with this or its related somehow.

When you turn the spur by hand it seems almost a full half turn before it engages the wheels....this is when it is engaging. I dunno. I have tried synching the slipper down but no help there either.

Any ideas??
