Hi Ron / Larry The kr2 LEGAL vne in UK is 135kt, the kr2s is basically a kr2 so vne is 135 (LAA logic).
We even need approval to change the prop, so go figure what the guys think about uprating the engine. Unlike your FAA relaxed approach, our folks insist on lots of design analysis before approving a major design change and 100+ hp is a big change from the original design approval which was for a 60hp vw. What would be the point of propping a plane for max pwr at climb speed, yeh up like a rocket but then revving the guts for 135kt. The guys at the laa aren't stupid they know it will be propped for a comfy 130kt cruise, so they take the low risk option. There has been lots of recent complaints about the LAA worry culture. I agree 100% the j3300 would make a good choice for a hot kr, but not sure how that fits with Peter Drake's STOL requirement. With 60hp I find it easy to get off and up 50ft in 300yds, but getting down in less than 500yds is pretty tough. Not sure how extra power would be helpfull.

The 0-235 and 0-290 are the largest Lycombings I'm aware of. The only "KR" flying with the larger engine was a TOTALLY re-designed airframe that was no longer a KR. It made the Gathering at Red Oak, Iowa back about 2002 or so and really wasn't all that fast for the horsepower. The 0-320, in my opinion, is way over the top for a KR and would be totally unsafe, in firewall weight and CG problems, if nothing else. If there are no reliability problems, I think the J3300 would be a great engine for a well built KR. Personally, I'd LOVE to drop a Continental IO-240 in my KR. 125 hp fuel injected with basically the same weight as my 0-200. I don't have that kind of money but at least I can dream. :-) Larry Flesner _____________________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
