Something to think about before spending all that $ on an MT - which I have been thinking about doing. I wish I had a solution for you, but I think you know the answer is to remove the bushings and drill. Maybe you can get MT to supply some bushings that are matched to their prop. Let is know what you figure out. Dave Leonard I have been working to resolve a problem for more than a month now and thought I would query the group for a possible solution. If anyone else is running (or planning to run) a 3-blade M/T electric prop with the RD-2C gearbox, I have discovered a mating problem in using this prop/gearbox combination for my 20B. The problem is the RD-2C prop flange comes with 3/8 id x 5/8 od bushings. The M/T prop has a stepped hole that is ľ” for the first 3/32” and then goes to 5/8”. Tracy is not comfortable with drilling out the 5/8” bushings and M/T adamantly advises against using anything less than ˝” prop bolts with this prop. So, I’m at a standstill until I can get this resolved. The only solution I can see is to press out the existing bushings and open up the holes to accept ľ” od x ˝” id bushings. But that would require disassembly of the gearbox and some precision machine work, possible but not my first choice. Mark S.
