Thank you @HvP!
I have chosen to go with a flap arrangement on the tail. The flap on the tail goes negative (up) which pushes the back down. It 1) keeps the theme of advanced programming, 2) does not mess with lift much (using the leverage), and 3) it looks like a plane.
The plane takes off like a breeze at 45 m/s. It climbs a bit much at the beginning, which I can likely modify. It lands acceptably with flaps, although the transition to landing position is stressful, again I think I can tweak that by managing the tail flap pitch better.
