I looked at your video and you are nearly there! Just a few comments.

I guess you were using some spare JR 8711 servos. If it is any interest I have JR 8411 servos for all the elevons and flaps on mine. 8711 is way overkill.

Most important though is that you must have more differential with the ailerons than appears on the video. You want about 25% down 100% up. If you have too much down the plane will fly on straight and will not turn as we found out on our first flight.

Heiner is spot on with the need for the incidence angle of fuselage/wing on its wheels to achieve takeoff. I have seen 5 Hortens flying now and they all have around 5 degrees angle of attack. Using the flaps with crow enables landings to be made with this angle.

I know you want to use scale exhausts, but if it were me I would make the first flight with exhaust extensions on. Then at least you can prove everything else works ok before you can try removing them.

Good luck with the first flight.
