Hi Tracy, good to hear that you're diving into the 2.85 drive for us

hold-outs.

Question regarding aerobatics.  I seem to remember, although couldn't find
it in the on-line literature, that you don't recommend doing aerobics with
the RD-1x (correct me if I'm wrong).  Are you going to build the prop

shaft

for the 2.85 a bit beefier to handle a few light duty whoop-de-doos that
the RV-4 was intended for?  I'm not asking for competition stuff just a

few

spins and mild hammer heads now and then 8-).

Feel free to post this to Paul's email list if you want to get a consensus
or a poll going.

Thanks,
Mike

The original RD-1 drive had a limitation of wood or light weight composit
props and mild recreational aerobatics.
There is no such limitation on the RD-1A,B or 2.85 version of the drive.
Aerobatics up through Sportsman competion level are OK on these versions,
even with metal props.
 For Sean Tucker type aerobatics, use the same guidelines he does.  He
changes engines (crank concerns & toasted cylinders) at least once every
season.  His annual maintainance budget is over $175,000.00.
