Horizontal tail glued on.
Also cut out the cowl mounts from the stock cowl ring.
I wanted to get maximum airflow through the cowl, and the stock mounting ring blocks it all off.
So I just cut out the mounting brackest,and glued them on alone.

My Roto 35 engine is a bit long with the muffler installed, so I will have to hack up the firewall to make room for it.

Had to remove the battery tray system which is pre installed inside the cabin area to make room for my modification in the next step.
