Lee, 1) There are a lot of non balanced KR's flying but they generally are those which fly slow. If your KR is going to be in the upper speed realm (150 +), I would definitely counterbalance the elevator. It is a fairly simple modification to add tips to the elevator to house the weights. Flutter is a killer.....why take the chance.
2) Since you have cut through the vertical spar, don't sweat it, splice it. I made the mistake of glassing in my vertical before the elevator was built and installed and I thought I was going to have to do the same. I would not try and remove the existing spar. It would be very difficult to get to the bulkhead area to do so. I would simply make a second spar and laminate (T-88) it to the forward side of the cut spar. This should get you out of the woods and you will have a strong vertical spar. 3) The builder of your plane should have left the mount nuts accessible. However since he did not, they may be floxed in place where the bolts may be removed. Why do you need to remove them? PS: Langford...I can not believe you gave up the "Glory". Hallelujah Brother!!!!

I am in the process of rebuilding the elevator and rudder. I have noticed several e-mails about elevator counter balances. My KR did not have a counter balance, is it all that necessary? On that same topic, I have noticed some people have extended the elevator outward and forward creating a counter balance. Would that be the easiest thing to do in my case? 2.. In the process of removing the elevator I cut though the rear support for the fin, against your advice, I regret to say, I will listen next time. Rather than trying to splice it back in would it be better to remove the old one and replace it with a new one. My concern about this is its attachment of the support to the lower portion of the fuselage. If all of the old support can be removed I should have a clean area for glue to attach the new support. What do you think? 3.. Another concern it being able to get to the top 2 bolts for the motor mounts. The back nuts on the mounts are in a void behind the fuselage that you can't get to from the bottom or the top. There are sealed in that area by the wood support on the bottom, and a piece of wood on the top that the front deck rests on. Not to mention the header tank being in the middle of every thing. ???? I would appreciate any help in these matters. My goal is to get this thing in the air by January, April at the latest. Thank you R.
