Carbon fiber is somewhat brittle, so I would not do that. I put an auto leaf spring on the Little Beast after the original got twisted.
We have the normal spring on this KR, but it's extension is very short, so I am anticipating no problems with the spring. I just wish I had that tail wheel that I had on the Beast. I also think we worry about too many insignificant things, but who knows what is insignificant until you ask? See N64KR at http://KR-Builder.org - Then click on the pics Daniel R.
