In Richard Johnson's flight test of the original Discus he replaces the

mylar seals with internal fabric seals & gets a noticeable improvement in

performance.



The mylar on my Discus CS is 20years old & starting to lift in places, so I

will need to replace it.



Has anyone out there done the internal seal mod?

Did you think there was any advantage

Can I have both internal & mylar seals?



The pushrod holes for Aileron & Airbrake are sealed with rubber bellows.

These are also 20 yrs old.

Anyone know of a way to test whether these are perished, no longer

sealing?



Many thanks
