I used a screen door cylinder last year and it worked alright except where I had the air inlet nozzle epoxied in was getting loose toward the end of the season. So this year I was thinking about going to an actual air cylinder. I have a 3 way solenoid switch and I am not going to get a new one. So I need a single action cylinder. I have looked online and I was wondering which sites have the best prices. Could I use a double action and plug one end and just let the weight of the prop bring the cylinder back down? Thanks in advance.
