Problem with worm clamps is that when the hose gets hot, around 150C, which it can do with radiant heat, the hose softens and under pressure will pull out from under a worm clip. I suspect that is wh

Karl you are right but all the hoses Rotax fit on the engine now have clips. It was a Europa factory molded hose that let go on me. Those hoses are fiber reinforced elastomer whereas the Rotax ones a

Karl could be that the clip is the wrong size for the hose. You maybe should ask the hose supplier what size to use? Similarly if you want to use spring clips you need to find out what size the hose

Andrew PVA release, (poly vinyl alcohol) is water soluble. It will be like a film and tend to peel off. Wet it and it will soften and feel greasy/sticky. I am not aware that the factory used it, too

All in my experience, (not as extensive as some on this list) the Eco prop is an excellent compromise. (whatever you do, is compromise in aerodynamics) Warp drive has good performance when stalled, i

Glenn no, Arplast baldes are too big to fit in a Warp hub. IOW Warp blade hubs are too small which is why they fail on Lycomings. The won't stand the vibration. (tortional mostly) Graham

Jos Stall ALWAYS occurs at the same AoA, never at the same airspeed. PLUS, the ASI will tell you you are about to stall when it's too late, you already have. AoA gives instant response and tells you
