    mine is allen 4A with short travel (about 12mm) btw all is matter of geometry and depends of the actuator bell crank length on the tab. It simply works with 12v connexion. the major difficulty is to build a cage in the control surface and a bubble .

    i'm not professional engineer btw i add my idea : the 4412 would be nice on that two equal spars type wing, very sweet stall and high lift.
    down side: the center of lift is moving a lot along the chord.  on avid wings, it won't be an issue

    the end of course is in servo , it stops automatically in the two directions
    on the allen paper, they say put 1amp fuse on the line, that's all. btw ray allen switch is very near mine. it's mechanical switch inverter

    Working on trim : Ray allen servo with a 0$ switch coming from Peugeot 205 electric window switch, tested it, works perfectly, i do not have the level gauge but i assume a visual check neutral in preflight.
    the servo will be inserted and bolted on a wood plate i made before covering

    the tab is an assembly of a piece of trailing edge riveted with a U sheet

    tjay...directly at protoplane, near the pyrenees, you can contact the boss by phone, he is a busy man but very kind and smart
    i flew passenger in a jabiru Ultra. it's a very soft and fast plane, you need air brakes to land

    i'm not very confident in your  mounting, you will lost muffler quickly, i suggest you put a lot of safety wires when you go testing it. 
    it seems you underestimate the power of vibrations. your side bolted of a 90° angular "chewing gum" aloy piece is very risky in my eyes.
    an other point is: original avid mount let muffler move with the engine to prevent cracks.
    take it not a judgement but an advice, i'll post soon a pic of what i've done, may be i need advice too
