I'm guessing if Dean didn't want you to haul them backwards he wouldn't have put the attachments back there for a tung mount. I had to go backwards with mine because I couldn't get over the fender wells of my car trailer. Tires are to wide.
Oh no that Engine mount doesn't work for you. Really sorry to hear that Allen I was hoping I was saving you a bunch of time. I hope you can get it sold and get your money back. You May use this picture to show what it looks like with the 582. That is if you decide to re-sell it.
when I land I add some flaps set throttle to Idle so its like a dead stick landing pull the nose up till you start falling holding 45 to 50 mph then about 50 feet from impact push the nose down slightly gain a small amount of air speed and flare. That's just the way I do it I don't like relying on that engine to get me to the landing spot.
I think Randy fitted boat seats in his Avid. I like the kayak option looks light weight but I cant imagine its any better than the sling seat. You could lay up some fiberglass like a kitfox seat. Then shape some foam.
