Motor Mount for the Chinook + 2 with a Rotax 582
I did not use the ASAP motor mount. It was designed for a "C" gearbox, but it pointed the propeller up into the air at a 12 degree angle from level flight. It seemed to me that if I twisted it to a higher angle, I would have something closer to a helicopter. I thought it might not be very efficient.

I had to move the engine about 1 1/4 inches to the rear and I still could only get it down to 3 degrees because of problems getting clearance for the prop. ( This explains why I moved the battery forward.)
I really hate to see engines and props bobbing around due to thrust or gyroscopic effect. That is why I wanted a really wide mount. Lord mounts were used, inverted, to get the engine as high up as possible. A shaft with another small Lord mount was used to maintain a verticle thrustline.
I am using a 3 blade Warp Drive prop that is 66 inches in diameter.
All pieces of the mount shown here in yellow are made of 6061 Aluminum. Two, 3 inch aluminum angles form the basis for this mount.
Control stick modifications came at about 125 hours.
The pivot bolt that ran thru the stick had wallowed out the hole giving play in the controls.
I wanted to make the rear seat stick easily removable for taking some passengers, and it makes getting into the rear seat easier. I can also carry more cargo, as when I need camping gear.
I made these machined parts to solve the problem, but if the factory was smart, they would Loc-Tite a slug into the stick before they form the end. I think this would solve the problem.
Photo shows the parts I removed.
