Well today's project turned out to be ''how to modify an E Flite nose gear to use in my beloved BH Corsair'' . So far it looks pretty good. I am not quite done with it but its a go. I ordered a pair of E-Flite 60 - 120 90 Degree Nose Retract Unit EFLG41190 . I broke one of my aluminum turnbuckles so I had to make one out of some Dubro parts.

If your original hardware is Ok then only one hole in the side of the retract frame tapped for the 4mm stud is required. The e flight trunnion will have to be drilled out for 5mm or what ever stud you are using. Here are a few pictures with the retract temporarily installed in the wing of the Corsair. Also a very short unedited video.

I would be very interested to know how that will work on a real landing. A similar idea is used on the H-9 Corsair factory retracts and they have big problems. Now they used cup and ball, not the same set up you have. If that can withstand the side load that is going to be applied at touch down that is great. Also being that this corsair is going to be in the low 20 pound range how sturdy is the gear going to be?
