Hello every body ... im new here and this is my first post here

so my problem is really weird that when im drifting with my mst xxx-d vip every thing is OK until I pull the throttle to the end (top speed) and turn to the right (only when turning right and full throttle)

The right wheel stop runing like the car is only 3 wheel drive . Its not stuck but dosnt conect with the diff ...

BTW I checked the diff and every single thing is really fine and super fine and its new and just start acting like this after a month before that every thing was normal 4WD and the diff is alum one way

and also its come back again 4wd after I totally stop the car and start over its start as 4WD but only when i go top speed with right turn thats happen ...

so dose any one had the same problem ?!!! Please I need help

......

the way a one way diff works is it has roller pins that only spin one way they have a stopper more or less the prevents this what i think may have happened is the diff has some wear on it and when you load up the right tire the rollers or slip pins as some call them no longer have the proper friction to hold it engaged with the throttle at full rpm i suggest getting a new diff hope this helps a little

I'm having the same problem with my HPI E10. I might take into account what supo54 said and might order myself a new front diff along with some aluminium dog bones.
