I’ve built two Senior Twins over the last 10 years. The first was a trike gear with OS55’s. I did do outboard and down thrust. It flew great and engine outs were no issue. It was kind of boring like a Senior Telemaster is suppose to be. Fast forward to this past Fall and I was bored and decided I’d build another one, this time electric and a tail dragged. Figured I could lighten it up and provide more reliability with electric. I also set the nacelles for 0 down and 0 out thrust.
I got the chance to maiden it this week. Couple of things popped up. As you know the lifting stab of the Tele quickly leaves the runway making the tailwheel a mere ornament. The left torque could not be corrected using the rudder. The only way I was able to takeoff was to use full power a little elevator and it was airborne in about 10 feet.
I have changed my thrust angles to give one degree down two degrees of outboard thrust along with changing one of my motors to a pusher. I have not yet had a chance to test fly it again.
