If the new IBU2U boards come with that issue fixed, try to update the board's firmware, not only your computer`s software. it will probably fix it too.

I have no IBU2U but for me, momentum and inertia are something I always add to my vehicles. If the board does not come with it, I add it myself with some advanced radio programming, it is much more realistic than jackrabitting back and fowards. I understand it is great a disvantage in an IR battle, but it would be ideal to have all the tanks in the battlefield feeling and behaving like real tanks instead children toys. Maybe in that board the momentum is way too much, and I agree it is a must to be able to disable it if requested, but it is a very cool feature anyway.

And yeah + 1 to the great loss of the ASPs and rc tanks australia products in general. :'(
