Dave,

   Not aware of a flexplate/flywheel replacement made specifically for use with 

Tracy's redrive but Dave Leonard (Turbo/13B-RV6) adapted an aluminum racing

manual transmission flywheel to his redrive after his flexplate developed serious

cracks while qualifying to race at the Reno National Air-Races several years ago.

  Perhaps Dave will jump in here with how he did it.......I know there are a series 

of E mails in the archives with photos of how he did it....As far as I know he still

is flying with this flywheel........FWIW

Hello,

I am looking for a flex plate for hooking up my 13B to Tracy Crooks redrive.
If that is not available, is anybody making a flywheel replacement?

Thanks,

I too broke a tension bolt several years ago and was fortunate enough to get
a set of the NEW ones 0.500" from a friend - highly recommended.
Mazda increased the size of those bolts for a reason and my original set
were all spiraled with silicone ... put a little silicone on the 0.50" as
well.

Dave,

Run a spiral of RTV around the body of those tension bolts next time you
remove them.  That will pretty much eliminate the vibration breakage.  Don't
put it on the threads.

Hello,

I am a newbie on the site. I have a Tailwind with a 13B and Tracy's controls
with his redrive. To this point I have been very pleased with the
combination. Last month I broke a tension bolt and have ordered new and
improved .500" bolts from Mazdatrix. My original .312" bolts broke from
vibration. I have 20 hours on the motor and never had any cooling issues. I
suppose that means I am over cooled, but that is okay with me. I will make
cooling improvements when I am back in the air. My 13B is stock and I run it
at 6,300 RPM.

Thanks,
Dave Williams
