I am fully aware of what a beta build presents (both risks and benefits) to any builder. Risks acknowledged and accepted. I will contribute any further ideas and mods, no charge.
This is half the fun of doing original stuff.
ps: Cosider adding another former between current f4 and f5 to better support the boom thereby not relying on the tapering stock at the rear of the pod. the tapering stock at the rear is for aerodynamics but is not strong enough for the torque loads imposed by the tail feathers. The extra former would absorb the torque loads and improve the overall strength.
