After the propulsion section it is now time for the steering. With remnants of a styrene plate a temporary servo holder was fabricated and together with the arms placed into the hull in order to measure the exact dimensions.
With those the final servo holder was built from several brass parts like 2x8mm and 2x5mm strips. The parts were then soldered and sanded. To fix the servo 2 M3 threads were added. The steering bars were from 1.2mm brass wire and Bowden cables from Conrad.
At last the servo holder was placed in the hull and fixed with superglue. To reinforce the joints I plan to use some adhesive resin.
