>> I do not believe that the CG limits were changed for the KR2S from those already designed for the KR2. They are still the same, which is why the standard modification is to add one bay forward and one bay rear for the total stretch.<<
There's only 2" added to the front of the S as opposed to the KR2, if you built them both by the RR plans. If you add a whole 'nuther bay to the front of a KR, you better have a really light engine up there! I know Ed Blocher added 4" to the front of his KR2S, and I'm not sure how he was planning on hanging a Corvair up there. You can modify a KR in many ways, but adding legroom has its limitations! Mine is "stock KR" in front of the main spar, and with the Corvair hanging up there a half an inch from the firewall (and no header tank), my CG is at the forward end of the range. Not that there's anything wrong with that (it sure makes it stable), but if I added 2", 4", or another bay, I'd have to have 30 pounds of lead in the tail (and my backup battery is already back there).
