Dear Listers,

  

 Looking for words of wisdom on installing the tip  canopy pistons.  It seems relatively straight foward, but I've been  wrong

 before.

  

 Are the measurements in the drawings  accurate?   

  

 Also, the instructions that came with the pistons  mention using foam and fiberglass to increase the rigidity of the

 side rails.   Has anyone done this and  did you notice a difference.

  

 Thanks in advance,

  

 John Brunke

John,

   

  We didnt have any problems with the piston installation by just following the directions. 

   

  The one thing I do notice is the minor flexing of the side rails when the canopy is opened and you let go if it that last 6 inches or so when the piston takes over and pushes it up. Increasing the rigidity of the side rails would be a good idea however there is not much access as there is barely enough room to get your fingers in there to place the nut for the support block so I dont see how you can get any foam and fiberglass in there.  

   

  As a note; the first set of pistons didnt last long and would not relyably hold the canopy up. The second set (from Vans) work fine.

What a timely thread.  

I believe the struts on my 6A have lost some of their lifting power at about 400 flight hours. What is that 2,500 cycles including building. As this has been a slow degradation I don’t really remember how much better they were originally but at this point I need to push the canopy all the way up to the last 12-14” to hold. Sounds like new struts for me.   

Are people replacing them with the struts sold by Vans C-690 at $27.00 each or are people buying else ware?  

   

Thanks,  

Robin
