Subject: [FlyRotary] Re: re-drive
question for George and Richard
yes, the 85lb is just the block as it is running
now. The FF, dry, will be 170lb. Keep in mind it is 12A based. The 13B based
will be a bit heavier.
Hi
Richard,
Do you
have a weight for all of your redrive components?
I'm trying to get a comparison to Tracy's 45 lbs weight, which includes
everything but the flex plate itself (I assume). When you add the
Hirth drive, mounting plate and hardware, input shaft, drive
coupling mechanism, what does it come to?
I think I
guessed that would all be about 30 lbs. Tracy's drive could fairly
easily be reduced to about 40 lbs, and possibly a bit lower if weight becomes
critical. Fortunately, it's not critical for me at the
moment. It's also yet to be seen how the RD-1C will cope with the
pulse frequency of the single rotor near idle. There may well
be some dampener durometer modification to be done. I won't know
until I fire it up, which should be around the end of the
Summer.
Thanks,
Rusty
(climb test will have to wait until tomorrow)
Hi
Rusty,
you could
not use the componet weights of my set up because the externals of my side
housing have nothing in common eternally with the MAZDA housing. My mounting
plate for the redrive is much smaller than what you need. My flywheel is 10"
dia, and the mounting of the adapter plate is very close around the flywheel.
Essentially, I have nothing further out than the tension Bolts, or for that
matter, the rotor housing outer contour.
Sorry to be
not of more help on this one.
