Wltoys K989 1 28 Rc Drift Project EP12 Install Sinohobby Mini Q One Way Diff Upgrade and Mod DIY Rc

In Episode 12 of the Wltoys K989 1/28 Rc drift project, we are going to upgrade the differential with a one-way diff from the Sinohobby mini -q one of the best upgrades for a 4 wheel drive drift car

The biggest improvement is not losing grip on the front wheels under breaking because the front wheels keep on rolling free and only the rear wheels break and slip

It´s just like pulling the handbrake on a full-size car to start the drift in the corner

It also gives you more oversteer and removes the understeer of a 4WD car

There is just one problem with this one-way differential upgrade don´t fit the K989

You need to pull both axles out and add two m3 washers on both axles and add some paper inside the cups

Removing the play between the axles and dog bone because if the axles stick outside the diff too much they don´t touch the special one-way bearing and stop doing their job

It´s a precise modification you can´t add to much paper inside the cup or your wheel starts to run rough and is like driving with the break on one wheel

So when you then release the throttle the car starts turn the way where the one wheel is breaking something you really don´t want

The things you need for this Wltoys k989 mods

14. Kevin: if you take off the front bearing of the carrier,stack it behind the rear beaning,put everything back together.That also works.
