I think you will find after you have a lot more time on the plane and start to fly it loaded at different C.G. locations that you will want an adjustable elevator trim tab, but wait and see first. You also might want adjustable aileron trim when you start taking passengers, but if so, a simple spring or bungee trim system vs. a tab will be enough. Might also be able to do that on the elevator trim with good results, but not sure that I have seen that on a KR before. Although the elevator forces are so light that you barely need trim it is good to have adjustable trim so you can take your hand off the stick now and then.
I would look at that spinner right away if it is causing vibration. As others have found, a slight vibration on the spinner can very quickly become a broken spinner which can also lead to prop damage or worse.

With the information that Mark sent me and the input from all of you my plane now has fixed trim tabs that work great. I determined that my aircraft was originally set up for a VW engine and I installed a Continental, witch explains the large trim tab on the elevator. Vibration; I have a very slight vibration at cruse flight. I know it's an airplane, but I believe that the spinner that I made has a slight wobble. _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
