You're right, Bob. But, couldn't see any advantage setting the prop off to the right of center line {:>). Yes, if the available gear box at the time (the Ross drive was about it) had had about a 2 -3" off set, I may never have discovered all the benefits and joys of "Plugs Up". {:>).
Again, the Powersport gearbox is a nice piece of work, just a bit too heavy and pricey for my aircraft and pocket book.

There is an offset on the Powersport unit which would lower the
engine. I guess in your case Ed, it would move it off to the side a
little. :) I would like to have had that feature as I could have left
the alternator at the stock location. It wasn't worth twice the money
though.

MessageHi David,
The bottom line is you can spend considerably more money, gain 20 lbs right up on the nose (tail in you case, where you probably do not want it) , not have the cheapness of standard Ford transmission parts to lower any repair (unlikely) cost and still not end up with any difference that the aircraft will notice. (other than the lighter weight of the RWS PSRU).
Now, I personally believe the Powersport looks very nice and it appears to be a well engineered piece of gear box. But, while it will make your engine installation heavier, it will make your pocket book lighter (but the one won't offset the other {:>).
From my viewpoint, I can get both an good rebuilt engine AND a RWS PSRU for less money . But, this all just my personal opinion.

Hi David,
Didn't recognize the name of that company but after going to the website I see it is just another name used by Atkins Rotary. The redrive is a nice one (same one developed by Powersport) but about 20 pounds heavier and more than twice the cost of RWS. Last time I checked it was $6500.00.

Any comments why I would want to pay double for American Rotary Engine's over RWS for a 13B turbo? This is going to be an installation that I am putting into my Cozy MK-IV playing off what John Slade has done in his Cozy.
