I'm going to agree with the others here... you may never consciously hit the extremelimits of your control stick travel. Thinking back though, I may have doneit a couple of times. I can recall practicing power-off stalls at altitude,and holding full aft stick while wearing summer clothing (no bulky jacket),I was surprised that after repeated attempts I could not get the nose to breaksharply and drop if I eased up to the stall. It would come up, bob, sink ratewould go up, then it would just dip to get a little air over the wings andthen repeat the cycle. In a sharper and intentionally rapid stall maneuver,I wouldn't try it but in a slow approach to full nose-up, I could hold the stickfull back in the bobbing cycle as altitude was rapidly lost and airspeed stayedin the 30s or low 40s. I'm quite sure I've never had the stick full forward!!!I have no desire to set a new world's record for elapsed time from cruiseto Vne in a homebuilt, but the Air Camper would sure be willing to try ifyou hit the forward stop!The time I think I've hit the aileron stops was in short-field slips to a landingon grass. Back at San Geronimo, I would come in just a tad high on final soI could get over the trees at the approach end of the field, then kick it overinto a hard slip to get in where I could use all the grass. I think I havefelt the stop once or twice in that configuration, but I could also be imaginingit because in that configuration the stick is well into your thigh. I havea 32" waist and weigh about 160, not a lot of meat on my thighs, but if you'renot slight of build the insides of your thighs will serve nicely as stick stopsin roll.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Corvair College 36 - San Marcos, TX, 1-3 April 2016

I'm in the final trim painting and assembly stage of my A-75-8 powered PIET. Ibuilt as closely to the BPA wt/bal data by Wm.Wynn as I could and also used anewsletter item that said BHP had recommended 3" aft sweep of the cabanes and14" (firewall to crankcase) length engine mount for the small Continental. PerWm.Wynn, I also wanted solid welded diagonal cabane struts, so to make sure thatthe wing position and engine mount length were correct, I bent 5/16" allthreadinto a temporary engine mount held together by cable clamps. I made the allthreadsthat protruded through the 4 crankcase lugs long enough that I couldmove the engine fore and aft, and with the aircraft on the scales, played cabanesweep versus engine mount length until I compromised at 17.5" C/G. Final positionis sweep 3-13/16" and engine mount 34" (using the same measurement locationsas Wm.Wynn stated in his articles). I haven't flown yet, but I'm deadcertain of my C/G. See attached photos.--------Planes&BikesRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/dscn ... ______Date: Sat, 13 Feb 2016 22:17:49 -0600Subject: Re: Pietenpol-List: Corvair College 36 - San Marcos, TX, 1-3 April 2016
