Ed,

I like how you made shroud mounting former, its really nice design. What are those metal end plate mounts for, looks like some sort of tube/rod mountings..I personally don't think Byron's shroud mount wouldn't be so strong to take torque n resist twists of new electric power systems, they were designed for glow engines who barely could produce 10-11lbs thrust on a good days...

Apart from Byron shroud, can Dynaemax system be installed in these models, wonder if anyone tried them and what were the results and what needed to be done to install those....
