So you no longer have a balanced elevator? I know the plans only discuss balancing the ailerons, but many people do the elevator also. I assume an unbalanced elevator must affect Vne, bit does it affect anything else? (And I know of another VW-powered plane that balances only the elevator and

I have been doing the annual condition inspection, oiling the hinges, making sure nuts are tight everywhere including the elevator balance weight, and not once considered that it may be an unnecessary item. Consensus appears to be that indeed the balanced elevator on a KR-2 is not needed.

Sid brings up a good point here, especially for builders that are early on in their projects. I think sometimes we forget that the original KR design tended to be a tail heavy design that was balanced by a large header tank in the nose. That didn't work out so great as it left the pilot

John, If I knew the actual answer to why so tail heavy, I would have fixed that long ago and would not be having all this discussion. The only plausible explanation I have is: The designer, Stu Robinson, set the RAF-48 wing 2-inches farther forward in the stock plans than it should have been.

There'd have to be a limit to how far you can move the engine forward using spacers. I'd expect even at 2" spacers would be starting to be prone to a bit of movement due to torsional forces and the like. I'd be looking to redo the engine mount if I needed to move the engine forward by more than

Spacers work well. If you still want to hang weights and you are opposed to lead, consider tungsten. It is quite a bit denser than lead and doesn't have the environmental concerns. A tungsten alloy that is available is called fansteel. https://sites.google.com/site/mykr2stretch/

Moving the wing forward would exacerbate the problem. The aerodynamic fix would be to move the wings 2-inches aft from the KR-2 plans callout. That is essentially what was done with the KR-2S. In the case of my already built (and flying) KR-2, moving the wings would amount to building

I'm no aerodynamicist but seems to me the proper way to fix this problem is simply to move the wings forward. Either that or shorten the tail. Using hydrogen or helium instead of air in the tires will help with buoyancy, which might help. This has the side benefit of increasing the service

The problem with using fuel as ballast is that human nature makes you think of that fuel as a reserve...it's not. If you require fuel to maintain cg then it has to be considered unburnable...burn it and you die. https://sites.google.com/site/mykr2stretch/
