My friend and I have purchased your #30103 Lipo belt drive starters and are more than pleased with the quality and torque. We really like the silicone insert that sticks to the larger plane’s spinner - without chewing out like rubber ones you can buy.
Unfortunately Hobbyking don’t have replacement silicone inserts available. You do have the rubber ones but why can’t we have the vastly superior silicone inserts as they are designed for large engines with large spinners?
Please help us out here.
