Thanks! ________________________________ Message 11 ____________________________________ Time: 10:46:10 AM PST US From: "Jack Phillips" Subject: RE: Pietenpol-List: Re: Tail wheel assembly weight John, Yes, the BHP Coil spring design works well, although it needs some modification from the original design which was for a tailskid, not a tailwheel. The first coil spring tailwheel assembly I made was done per the plans, with the only difference being to mount a tailwheel rather than the shoe of a tailskid, and I ened up with the tailwheel aft of the coil spring. I do have a steerable tailwheel, and what I found was that the steering loads on this design caused the whole assembly to twist, rather than simply turning the tailwheel. Here is a picture showing what it looked like: I flew this assembly for about 3 hours, then one day while taxiing for takeoff, and turning into the wind, the whole assembly twisted so much that it broke. I went home, redesigned it, and made a new one that has worked well for the last 250 hours. Here=99s a picture showing the difference: The first change I made was to do it more like BHP=99s tailskid and put the wheel directly underneath the coil spring, eliminating part of the moment causing the twist. The other was to add the stiffener near the open end of the fork, turning it into a much stiffer A-frame. Note that this requires using bolts to attach it to the fuselage fittings, rather than springing clevis pins into the fittings as the BHP plans show. The only thing I wish I had done differently is that the angle of the tailwheel kingpin is leaning slightly too far aft, which can cause the tailwheel to break into full swivel mode a little easier than I wish. To fix this will require making a whole new assembly and it isn=99t enough of a bother to be worth that.

With a record crowd, from as far as Texas and cheers from the horse stables, first time entrant, Gary Boothe's mighty Corvair powered AirCamper ran flawlessly. With 260 lbs of thrust, it strained against the ropes trying to tame it. Without actually moving the truck, He was easily the winner! Upon post-run inspection, it was discovered, that Gary's pilot, Curt put his weight into the pull. While holding the brakes to prevent the clip-winged Piet from getting airborne, he pushed his dairy-air too hard into the back of the seat. Gary now has a Broke Back Piet. With some reinforcement, posting of pictures, detailed description and sketch-up drawings, he'll be ready for another run in less time that it takes Kevin to change a broken spoke.
