My cabane struts are long, and its very easy getting in to front seat.I agree that a heavier engine should make for a shorter cowling not longer.Here are a few pics of the uncowled plane and a better pic of a Tigre.. it hasquite a bit of stuff hanging off the back.My wing struts are way too long in the pics, about 9" long, they have not beencut to size and finished yet, but I needed something to put in for photos.JimRead this topic online here:

>From what I understand, the Continental C-90 is probably the ideal Pietenpol AirCamper engine. It is rated at 90 horsepower, 95 for short periods. Even thoughit has less horsepower than a Corvair or O-200, it can swing a larger diameterprop, which is ideal for climb and also to overcome the Piet's drag. Asfar as weight goes, the less, the better, but the Ford weighs about 240 lbs.I think the C-90 comes in at about 215 lbs with all the little nicknacks anddoodads. Anybody feel free to correct me if I'm wrong.NickRead this topic online here:

Jim;Just for comparison, NX41CC in its most recent W&B (using electronic scales) had29 lbs. on the tailwheel in the level configuration, empty.You should weigh it and see if you really have 50 lbs. on the tail. I would thinkyou would require significantly higher elevator force to raise the tail ifit's that much heavier back there.Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Mon, 12 May 2008 12:10:11 -0700 (PDT)

Oscar,I will be weighing it next time I put it together, they (A&I and Kitfox guy) offeredto loan me a set of scales and help out, so when I get to a good point todo it again thats the plan.May be less than that, but felt mighty heavy holding it up.Next time it goes together I want 2-3 knowedgable helpers on hand. Want to havetemporary struts the right length, and good supports for everything. Also a lotof clamps/markers so we can do a trial run of all the rigging and mark allthe fitting locations. Need scales, levels, etc. And a clear plan/checklist sowe can get it together and apart in a day and still accomplish enough to makeit worth while. Going to get more/better quality pictures too.In the mean time, I am working on getting the wood leading edge for the lower wingsfabricated, ordered 1/16th inch okume ply for the wrap, and will be checkingon getting exhaust stacks made.jimRead this topic online here:
