Hello John Buckner and thanks for the guidance.

I understand and accept most of what you offered. But not plastic in plastic?? I see so many pushrods set up that way that I expected it was standard!!

I'm a newcomer to the hobby and don't have a large collection of miscellaneous bits and pieces and I don't have the materials you described, nor immediate access to them. I want very much to have this old Kadet ready for our club float fly next week so I've gone ahead with what I do have on hand. I found some gray platic tubing that seems OK with the required bending radius (came with an old ARF package). So I used it as the outer sheath and standard yellow innards. I fabricated the water rudder hardware from brass tube, rod, and shim stock, connected the whole thing, and it seems to work OK. Only time will tell!!

I think this system will convert back to wheel landing gear pretty easily. The gray (and yellow) push rod will pull right out after removing the clevis (leaving a small hole in the fuselage). Then the front wheel push rod will connect again to its servo arm.

The methods you described are totally new to me but sure make sense. I'll look more closely at them the next time around and, for sure, if my method doesn't work well enough on my old Kadet!!

Thanks for the help. I've got lots to learn!!

Frank
