Here is a You Tube Video of an A-65 running on a Zenith 701. I am also going with
a Continental C-85-12F with a light weight starter and alternator for my 701.
I tried serveral time to contact the video owner but never got a reply.

Turned out great, just short on airplanes. Oh well had fun and a B25 and twp T6's
stopped by for a few hours! Not so bad! Mike ( local A&P) had a little work
on one of the T6's. Chip sensor picked up something... Hope it does not pick
up more!
Stop by next year we will be here!
I did forget the camera though!!!!

| Subject: | Rotax 912XTRA ?????????? |
I have now seen a older Black Rocker box cover 912A, made back in the 90's,
it has a kit installed that is called the 912xtra by Masterkraft. It is
supposed to boost the HP by 10 to 15 hp.
Does anyone have any experience with it, good or bad please speak up, if you
want sent private email but please let me know some info if you have any.
Thanks
David M.
