Team,

I picked up on this email chain as it may affect me directly.  I recently purchased Mark Steitle's 20B and have been mating it to my airframe over the last few weeks.  If I recall correctly, Mark had a modification to the RD-1C prop flange for larger diam bolts but do not recall any mods to the flex plate / isolators.  If anyone knows otherwise please share.

Thank you!

Greetings all. I need a little advice, if you would be so kind.

I have a RD1-C, with the flex-plate rubber isolators, which I am currently marrying to the un-modified Renesis that I have just rebuilt.

Reading Paul's list, he was talking about replacing the 1/4" bolts (flat head screws) that hold the ring gear to the casing, with 5/16" bolts because he found them sheared in a unit that he disassembled (unknown was the power plant modifications that drove the reducer.)

What, if any are the recommendations to do this alteration?

Thanks in advance

Rich


Well first, continue to read Paul's list, but keep a large container of salt handy, with the aperture set to 'pour'.

Others may have better recall than I, but I'm pretty sure the drive in question was Mark Steitle's, running on a P ported 20B (3 rotor).
