I think its a bit unstable in the yaw department. Could be the motors are not in sync but I dont feel thats what the problem is.

Felt like the wind would catch a wing and alter the heading slightly. If left hands off it takes a while to correct.

I think I'm going to add vertical wing tip stabs. I think the extra wingspan and no extra area on the fuselage makes for a greater effect on the heading with turbulence and wind, the other option is to extend the tail or add area in the tail plane but I'm already using ballast to correct CG so dont want added tail length/wight

Motors and servos installed. Very rough setup with excess wires and too much tape but worthy of a test flight. Seems to have a lot of thrust! Vertical take off?

AUW with 2200 3s 606grm. I'm using my night flying fuse so an easy 100grm can be shaved off there and maybe another 10-25grm in wire tidying.

Nice day for a maiden. Cross your fingers for me

Pictures and maybe video later

I decided to see what would happen if I joined 2 wings to get a twin pusher setup. Im going to use this wing with a standard fuse and as the motors are not over the tail boom I can use up to 9" props!

I have used the 2x CF strip you get in the kit and widened the channel between the motors so they can over lap at the wing joint.

I have noticed that the ailerons on the MS are a little vulnerable and the tips are easily damaged even in a good landing, so on this build I have shortened the control surface a little and left some of the tip attached to the wing. I filled the gap with foaming Gorilla Glue and cut it to shape. This gives me a core to fiberglass over.

I think getting the CG far enough forward is going to be tough so for this build I will fit the elevator servo in the forward fuse. I may also go for rudder on this build.

not sure how it will fly as the tail control surfaces are not directly in the prop wash and so might not have as much authority. I may need to enlarge the elevator?

More updates as the work gets done, might epoxy glass the wing later today
