This would be a good point for me to get input on interest

on the 2.85 : 1

drive.

Tracy,

Tracy, would the 2.85:1 handle the single rotor any differntly then

the 2.18.

6.5 B group what say you!

Tom,

I am not certain I can justify the weight of a 400 hp redrive for a 100
hp ? single rotor engine. Most of all I am concerned about the gear
rattle aspect. Our 6.5 B engines will have 1/2 the number of 13 B torque
pulses for a given engine rpm. That might put the rattle at a rather
inconvenient prop rpm.

How about it Tracy, is there any reason to think that the 2.85:1 redrive
would have less rattle than the existing unit ?

I have been helping the local AIAA group on a flyable replica of the Wright
03
flyer. They have a VW lash up for first testing  a Revmaster and a non
reversing 2.85
reduction drive (maker unknown that Joe also provided). I grabbed the output
shaft
and there was absolutely no perceptible backlash (to my surprise)
