I replaced the struts on my 1987 Cobra trailer in 2009 (Ventus cT with
17.6 meter tips on the aft roof). Spindleberger said 850 - 900N was
correct. John Murry (Easter Sailplane) recommended 900N, 46" extended
length. Installation straight forward provided you note that the lower
end of the strut is secured with a circular plate with 2 pin holes for
a pin wrench, and one of the holes fastened with a screw. New struts
were a moderate press fit into the inner square tubes.
After removal one of the the old struts had a 800N label.

I have a strut dying (dead) on my trailer. Need to order two, so I got online and Wings and Wheels has them. It's a '98 trailer, so no placard with the strut force on it. It is an aluminum top, with no insulation, and houses my 1982 ASW-20a. In the
top is my horizontal tail, and two M&H winglets. There are also two 18m tip holders, but of course, no tips in them. My quandry is whether to buy the 900N or 1000N struts. WW says the book recommends 900N for 15m or 1000N if CL, which I assume means
the extra 40 lbs needed if the tips were actually in them. It seems like the trailer was probably built for a glider with CL or maybe 18m tips, in which case it would have 1000N gas struts. If anyone shed any light on that, with any recommendations it
would be greatly appreciated.
