Hi again Kevin, thanks for posting the photos, your setup looks truly simple, though I would be concerned if I was going to attempt landing on that setup (looks small in pics), though I believe the geometry you have used with the full down stop position would more than work. Do you think that the wire you are using for the axle is strong enough for an aircraft of this weight if using this for take off and landing, on a grass field?...I am just thinking that if I do go to create a masterpiece such as yours that I may wish to consider at least once flying the plane off a grass field. How did you fix the axle wire into the brass rod and are you sure that the brass rod will not bend on a landing?...I think if I am going to use a setup like yours I would prefer to use both axle and cross rod in a hardened steel rod and I suppose I will have to get a welder to ensure that this will not come lose in any way.
I have never even held pneumatic retract cylinders in my hands so what type/manufacture have you used and what size?...and did you strengthen any other areas where the cyliners are mounted or where the rotating portion of the axle exists in the fuse?...
