The Mi9 has been refined in many key areas, optimising it’s centre of gravity, unsprung mass and reducing it’s polar moment of inertia with tactical weight reductions.
With this in mind, we have introduced motor mount weights allow for the perfect placement of additional weight in order to meet weight regulations in the best possible way.
Two versions available:
This one, U8815 – Motor Mount Weight 22g with Stock racing in mind with maximum pinion size 37T 48dp 50T 64dp.
The weights are attached to the kit motor mount. |
