I plan to get my CHT and EGT sensors in this morning, cut the bottom cowl for the exhaust stacks and test run the engine this week!

Message-ID: <20020506.093907.-586263.0.virgnvs@juno.com> Yes, the Elevator is balanced to prevent the possibility of flutter. It may also reduce the force needed to move the elevator, but that may be a moot point. You may do this by adding weight to the foreward part of the control horn. Or by placing 2 weights at the end of the elevator on booms extending forward of the hinge line alongside the end of the Horizontal stabilizer. Check out the newsletters on how it is done. Also check on balancing the ailerons, Virg On Sat, 4 May 2002 19:39:08 -0700 (PDT) David Hartz writes: > EXCUSE MY IGNORANCE? > DOES THE ELEVATER NEED TO BE COUNTERBALANCED TO REDUCE > ANY POSSIBLE FLUTTER OR ANOTHER REASON? > DAVE HARTZ /KR2\ > > > > > ===== > DAVID HARTZ,WILLITS,CALIF.

I questioned that statement at the time but I just this morning got around to checking my set of plans. On page 19, drawing no. 12, my plans state " 3/32 plywood, 3 ply mahogany, birch or poplar center, plywood on .....". Are the newer plans different or did someone misinterpret? Larry Flesner ------------------------------ Date: Mon, 06 May 2002 09:19:54 -0500 To: krnet@mailinglists.org From: larry flesner Subject: flutter / Bingalis books Message-Id: <3.0.6.32.20020506091954.0086fab0@mail.midwest.net> Netters, Several post on "control surface flutter" lately. I'll add my "opinion" to the mix. First off, flutter is not a matter of speed only. Several factors come into play to produce flutter. Control surface flutter can happen at lower speeds than some have stated in their post, i.e. 140 MPH or so. I have a friend that was flying his small homebuilt with a full-flying- rudder that had some "worn" bushings and he got flutter that caused the rudder peddles to beat the "p-ss" out of his leg before it stopped ( he was VERY LUCKY) . The flutter stopped before the the rudder came off. This may not have been a case of true control surface flutter but it sure got his attention. I also witness a case of true contol surface flutter on a jet powered model. At the start of a high speed pass it made a moaning sound for two or three seconds before disintergrating before our eyes. They hauled it in with a basket. I'm not an engineer so I won't try to give all the variables but they include things like (air) gust loads, etc. The designer attempts to "build out" flutter and your best defense is balanced control surfaces. This is an area you don't want to be "experimenting" with. Educate yourself on the subject and build accordingly. Speaking of educate yourself, as President of our local EAA chapter I recently got the package from EAA on the May book and tape sale. All books and tapes listed are 50% off for the month of May when combined in a SINGLE chapter order. The Bingelis books are included and all four books can be purchased for $40 US or $12.50 US singlely. If you don't already belong to an EAA chapter you should and the savings will pay for one years dues. My opinion, if you can't afford all the information contained in the four books for $40 you probably won't ever finish your project anyway. He not only covers the subject of flutter but covers every subject you need to know about from picking a plane to build ( you've already done that), setting up a shop, fiberglass tanks, standard panel hook-ups of instruments, wiring, etc. to the paper work to get certified and everything in between. They are NOT dry, hard to read tech manuals but read so easy you won't want to put them down. Order your engine, aircraft, and propeller log books now for half price also. Through in a "Sky King" video or two to remind yourself why you're building that thing in the garage anyway. ( now you know where I got the idea for a scale "Bamboo Bomber" with twin Corvairs from). The offer is good for May only so act fast. Now , out to the garage!!!

Whenever you flox " blind nuts" , bury nuts in areas for latter attachment, etc. have enough nylon bolts of the same size available to screw into the nuts while the epoxy cures. This keeps epoxy out of the threads and latter assy is a snap.

Charlie Airesman removed a O-200 from his VariEze and replaced it with a 2.2 Subaru, direct drive. He started out with a 52 inch Warp Drive adjustable, but the ground roll was to long to suit him. He tried cutting it down and running 4000RPM, but the ground roll was longer. Then Gary Hertzler designed a 53 inch prop for 4000RPM with a 61 inch pitch, which Charlie built himself. It significantly reduced his takeoff roll and increased his rate of climb. Top speed was only down slightly. My thoughts were that we could get quite a bit more power out of auto conversions by running at the higher RPMs and without goings to reduction drives.

The answer I got was that the newer plans do call for birch and cover both sides of all spars. I would not plan on using something other than called for in the (old) plans but I would cover both sides of all spars. I've never heard of a KR wing spar failure. Don Becham (sp) claimed he punched his wing through a metal hangar when testing those slick looking retracts with no VISIBLE spar damage. I'm sure this is not an approved testing method and your results may vary!! He then spit his wad of "Scoal" into an empty soda can and strolled out behind the hangar to flip the pork steaks.

Of course, if the stubs are finished, this will entail cutting them up a bit, but it is doable. I had a tailwheel very similar to the one on page 215 of the Aircraft Spruce catalog, with the 4" wheel and liked it very much. Daniel R.

If the main gear brackets and legs have been mounted for a nosewheel config. , I'm thinking you would move the bracket and leg from the rear side of spar on one side to the front side of spar on opposite side to convert to tailwheel. I'm sure the mount holes in the spar won't match so close old holes using accepted practices (don't ask me, I can barely spell it) and drill the new ones as close to center of spar cap as possible. Your best bet would be to call Dan. Do a net search for Diehl Aeronautical for the phone number or maybe someone on the net will supply it by the time you read this post. Good luck.......
