Attached are the final install pictures with the KingTech 210.

I added carbon plates to the undersurface of the motor mount rails to for durability and I added a hardwood removable stop (black) in front of the tank. The tank is otherwise secured in the back with a single bolt. I added a second second vent line to the tank and went around the seam with carbon fiber. Finally, I changed the metric canopy screw in the front to the classic BVM nylon bolt ala King Cat/Bobcat/Bandit.

The model weighs in at 39.5-40 lbs dry (rough estimate, me holding it on a scale) and has no added weight.

After flying it I was able to move the landing gear/brakes battery back to the main tray in the cockpit. I will report back on my CG when I can get an accurate reading but as is, I think I can move it back further by exchanging the heavier ECU pack for the landing gear battery or even moving them both in the cockpit.

I have probably 25 flights on it now and am feeling pretty comfortable that it will be ready for some heavy use at First in Flight.

I am currently carrying about 3mm up trim in the model and hope to decrease this as I fine tune the CG.

I use triple rates on aileron and elevator:

My low rate aileron is 21.5 up, 15 down and 40 mm up, 27.5 down for the high rate. Middle rate in between and all rates have -25 to -40 expo.

For the elevator I am using 13 mm up and down for low, 23 mm for the middle rate and 30 for the high rate. I carry -15 to -40 expo for these rates.

Above are all measured at the inner edge of the respective surface.

For the rudder I am using 33 mm for low, 44 mm for high rate and the flaps have 130 for full throw.

I have settled in with 8.5% down elevator/flap mix as the model climbs with flaps.
