I don't think anyone makes the geared handle type, or the thimble type handles anymore.  I think the geared type only worked on fairly heavy models.  I have a thimble type, but don't think it is strong enough for much bigger than a .15.  I thought of making a handle, but it is way too much trouble to make just one, and no one flies it any more except the few remaining speed guys.  I would be surprised to see one do any stunts.  Maybe a pistol grip transmitter on monoline will be the new monoline.
