There is no twist in the fuse of the cap in the picture. Here's why.
The original owner crashed on his first flight. The gasoline tank burst and the gasoline ate the foam from the firewall back to near the end of the canopy.
He threw the remains in the field trash can. I went dumpster diving and salvaged the remains.
I rebuilt the fuse from the rear of the wing forward out of 1/2" balsa. I figured the forward weight would help. I used some parts (canopy, cowl, etc) from a kit I had on hand.
The new front section was glassed onto the old rear. Thus no twisting. I would glass the inside of a new kit at that turtle deck - rear wing junction.
I have the remaining kit parts stored somewhere. Just have to remember where and dig them out.
The control setup was per the manual. It flew fine.
