I am hoping someone here can help give me some hints on building the diff, so the diff cup won't pop off during running ... Thanks!
In case of ST07 outdrives popped off the geardiff please:
1. Check the inner OR05 O-rings. The rubber material of both O-rings should be hard. These O-rings should be noticable harder than any conventional o-rings that are using in others RC cars.
For example our OR02 O-rings for balldiff are noticable softer at about the same sizes. So the mistake in O-rings is possible.
2. Don't fill too much oil inside the geardiff ! The enough amount of air should be inside our geardiff.
