Guys,Another way is to use fabric when covering, but you can't take the elevators off without cutting them.Regards,TomOn Sep 29, 2009, at 3:42 PM, gwread(at)aol.com wrote:>> I used 3/8" M-D rubber weather seal.

Hi Jeff,They are forward! Here are my observations.When you sit in a Cub on the ground, with the birdcage and all the cabin around, if feels like a ridiculous angle. Given that, with the VGs I am able to climb and sustain a ridiculous angle as well. Stalls don't really seem to happen. It just kind of gets mushy, nods its head and loses altitude. There is no real break. I haven't spun it yet so not sure how those are affected.Now I am not the highest time Cub pilot in the world as I probably only have 60 hours in them. This is the fourth one I have flown and like Cubs (and all airplanes) each one is exactly the same --- they are all different. This had the VGs on it when purchased so I can't attest to the flying qualities before they were installed but I can match it against the 20 or so hours I have in other Cubs. Please also note that I don't really fly by airspeed indicator but how the airplane feels, sounds, reference points, etc.So, compared to the three other Cubs I have flown, the sweet spot on climb is 50 indicated compared to 60 indicated in the others. I cruise around 70 and that seems a bit low to me with an A-75 but it is a dirty old Cub with a 980 hour engine. I can approach like a rock at 40-45. The stall speed is placarded at 23 mph. I don't know how that number was attained. One thing I really like is in a gusty crosswind, I can horse it off the ground very quickly, establish my crab angle and continue out. I seem to be able to handle more of a crosswind that way. The only thing I really don't like is I have to fly the plane all the way to the hangar. The wing always seems to be close to flying. That may be my low time but I still pay a lot of attention to control position when taxiing in any sort of wind.Jeff, what do you think of yours and how does this compare?-john-John HofmannVice-President, Information TechnologyThe Rees Group, Inc.2810 Crossroads Drive, Ste 3800Madison, WI 53718Phone: 608.443.2468 ext 150Fax: 608.443.2474Email: jhofmann(at)reesgroupinc.comOn Sep 30, 2009, at 11:36 AM, Jeff Boatright wrote:> >>> Wow, those are a lot closer to the leading edge than mine.

One other think I forgot to mention. I seem to run out of elevator in the flare. That may be my stomach but I have heard this from other Cub drivers with VGs. There is a new set of tail VGs out that I am thinking of installing this Winter to see how they work. I have also lost five pounds so that may help. Almost a gallon of gas.A few pictures.Our own Jack Phillips and Glenn Thomas when I went to pick up the planeReady for the big adventure from North Carolina to WisconsinVirginia Tech off the wing and ready for the mountainsGround speed was 27 mph when this was taken.

Re: Pietenpol-List: Spar splice

Post by matronics »

Original Posted By: Gene Rambo
Would it not be acceptable to continue the splice plates further outbord so they also became the reinforcement plate under the cabane fittings? The actual splice would be away from the fittings, the plywood piece would be larger and stronger and the whole spar should be stronger. Also at the very center both the bending loads and shear loads are smallest.Mike going to buid a one piece wing ----- Original Message -----
