It's good, strong, simple to construct and very safe if flown within it's design envelope. There are many areas for design change, I didn't say improvement, I said change or variation. No matter how you build, wood or steel, 1.7 oz or 3.5, Stits processor Wal mart vinly you will still arrive at the same performance, TO 40 MPH, climb50-55, cruise at 65. Unless diving when you might get up to 70.So why can't any of us vary the construction dimensions to better accomodate our physical variations. NX41CC was tight for me, 68 in and 195 lbs. My test pilot, Edwin Johnson, had plenty of room and was comfortable but he's about like a fart in a whirlwind. When I began building NX311CC I decided to build an airplane which would be comfortable to fly either short flights on cross country. I chose the long fuse design, wood construction and powered by the A65 engine and the three piece wing. These are the changes from plans I made:Widened the fuse from firewall to top of passenger V to 27in, wish I had gone to 28in.Moved the rudder bar to passenger feet and used Bellanca pedals w/ toe brakes for pilot. Will have to raise passenger seat so my toes won't drag on passenger's rear end.Used a control column from a WWII Fairchild PT 19 or 23. Then a torque tube to the elevator horn via a walking bell crank.Nine stringers instead of the seven for turtledeck.Two stringers for fuse bottom and three for each side.Cut top longeron at passenger starboard side for a seven in hinged door. Strengthened with 1X1 spruce to guarantee fuse strength.Widened wheel track from 56 to 66 in.using steel coils for shocksCenter section spars 33in. Cabanes raised 4 1/2 in. The cabanes are not vertical but widened at the topNow I won't guarantee this machine will fly but I assure you that if I give my Test Pilot enoughDewar's he will sure try and when I fly it I will have plenty of room for radio, peanuts.Hope this let's you know what a fool I am and that it may help solve some of your problems.A Louisiana builder________________________________________________________________________________Date: Sun, 13 Nov 2005 19:51:36 -0500
