Colin, BE CAREFUL! I don't know what you mean by "60 degree LEVEL bank turn". Just today at the gathering we discussed max stress on the KR. It was established that the KR is max stressed to 7 Gs at 800 #. Meaning a total maximum supported "felt" weight of 5600 #. So if your gross is 1400#, your max G load is just shy of 4 Gs. If at that gross weight you make a turn at 60 degree, your "felt" weight is 2800# IF THIS HAPPENS IN BUMPY AIR, YOU JUST MIGHT EXCEED MAX LOADING, MAKING YOU THE TEST PILOT!!! Caps were not intended, but appeared at the right time! I'm not exactly clear on your intended message but want to warn everyone NOT to exceed the load limits! Joachim

The Piper Seminole twin engine aircraft is rated at +2 -0 G's and is a wonderful crusing aircraft for normal category operations. For most people who fly KRs normal category type maneuvers is very common. I am willing to bet that most KRs never see more than 1.5 G's their entire life. If one likes 60 degree banked turns maybe just over 2 G's (60 degree LEVEL bank turn in any aircraft is 2 G's). The critical point is not going to be the weight, it is going to be the location of the CG. This will have more of an effect on the plane's safety than any other ONE thing considered. The second most important thing is the engine prop combination. I would think that the VW would never suffice as a good engine for this weight. Either O-200, Corvair 6, or one of the other higher output engines would be appropriate here. Also the testing phase is going to be very important for this aircraft due to the influence on the flight characteristics and most importantly, the speeds that will inevitably change. IF well built I can see this plane with proper CG control being one of the more stable KRs out there. Just don't try a Marty Roberts arrival move! > > Case in point, look at the Gathering pictures from before and take a look at the modified KR with the O-320 Lyc on the nose. > > Colin & Bev Rainey > KR2(td) N96TA > Sanford, FL > crain...@cfl.rr.com > http://kr-builder.org/Colin/index.html > _______________________________________ > to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net > please see other KRnet info at http://www.krnet.org/info.html
