the tubes in the plane are straight , there is almost no bend at all. yes the carbon tubes are stiff and that is why I want to go with them.
2x56 tread in very tight threading into the carbon tubes , don't think they will come out.
did not think of JB weld. I do like JB weld The masking tape was a good reminder.
I had to do something as the tubes end before coming out of the tail of the plane, so I could not use flex golden rod push/pull.
I am bouncing back and forth between a P-26 and the PT-17, lots of fun, till the wife makes me go out doors. Lol
thanks
