Hello,

I fly out of Hobbs, NM where we don't have a tow plane. We launch strictly by auto-tow. I am interested in a Russia AC-4B but am not comfortable ground launching from a nose hook. We currently fly Schweizer 1-26's and a 2-33, which has the hook located between the nose and the CG. When you climb high enough you can get a porpoising effect due to the tail stalling & unstalling. I would imagine this only gets worse with a hook in the nose, but I can't find anyone who has done it. The manual indicates that it can be done, but I wonder how much height you have to give up due to the hook location. I am also a little concerned about the angle being too sharp on the nose hook and possibly keeping it from releasing.

Has anyone flown (or seen) a Russia glider ground launched by the nose hook?

Thanks in advance,


Stephen

https://groups.yahoo.com/neo/groups/ac4/info is a Russia glider yahoo group.. You might get a response there. However, I don't recall anyone ground launching one on the group.
