Gentlemen I have a problem with you discussing this thread in that you maybe considering, reducing the size of your rudder. If you are considering this then please remember that in Darryl Stinton's book "The Design of the Aeroplane" he talks about the size of the rudder will never be addiquit for all situations encounted while flying an aeroplane eg. Spins, the rudder will be shaded by the horizontal tail and in this situation you will need as large a Fin/Rudder as possible to counter the spin and pull out. Ok you may not be planning on doing spins in your KR2 but you never know what situation you may find yourself in and this may be the time you need all the Fin/Rudder you can get. Please don't believe me. I suggest that you read a few books on the subject, look at the volume coefficient for Fin/Rudder sizes on other aircraft. find out what the average co-efficient is for other aircraft and then calculate your own Fin/Rudder co-efficient and err on the side of caution. I think you may end up increasing the size of your Fin/Rudder.

I missed the earlier part of this thread because I was on vacation, but I agree there hasn't anything in it proving that the rudder should be reduced. KR's don't need much rudder on turns, as some of the old Newsletters discuss, because the aileron is very well designed, and the gap that opens on the "up" elevator largely compensates the induced drag on the "down" elevator, unlike old-fashioned ailerons that require lots of rudder to prevent yaw. However, a plane uses the rudder for many things besides turns. Even on the 152's I fly, not much rudder is needed for turns, but for a serious forward slip I'll often use the whole thing. If, like a Cessna, a KR can use all the rudder travel for a slip and have aileron travel to spare, I wouldn't consider the rudder too big. Concerning spins, the old Newsletters also have several accounts of people doing light aerobatics in KR-2's, including spins, so the rudder does not need to be bigger just for spin recovery. I haven't seen any accounts of spinning a KR-2S, but presumably this should recover equally well, since the rudder was enlarged.

Rex, I don't know what Matco cylinders you have, but I'm using the MT-MC5 which has a stroke of 1.4". I checked my pedals and they have a max motion of 1.25", but I can't imagine how much air you'd have to have in your lines to need nearly that much. That translates to a total angle of about 70 degrees. If I keep my brakes on my plane like I keep the ones on my car, it won't take much pedal movement to stop it. According to the Wicks catalog, the MC4 has a stroke of 1.38, and the MC4A has a stroke of 1.5 inches. It won't hurt to make the lever arms longer, but space was my main driver. I'm only 6 feet tall, and I was just plain out of leg room. And you have to have room to run your pedal return pullies. In a marvel of trial and error fabrication, I arranged it all so that the rudder's max travel coincides with the pedals hitting the firewall. That leaves very little room for the return pullies, which are located about half way up the pedal. Next KR2S I build will have an additional two inches betweeen the firewall and the main spar. Although I have some recent pictures of those return pullies and the severe shortage of space, I haven't bothered to put them out on the web yet, but I'll do it tonight...

I believe one of the figures has the part number. However, I ended up measuring the length I wanted, and ordering a specific part from ACS. I think the length may depend on how many layers of glass you use on the spar etc. I choose the machine screw with a "grip length" that is, it was not threaded up the entire length. This screw has a greater strength than the others. I don't recall the MS number however. - -- Regards Ross Harold P wrote: > > Saw this on the net and wonder if anyone can help this fellow! > > Harold > Montreal > > ------------------------------------------------------------------------ > > Subject: KR2 part number > Date: Wed, 19 Aug 1998 09:13:21 -0500 > From: "Dennis L.

Also stay under 300# per scale as they tend to top out at 300#. I just happen to have some 90# bags of cement which I can use to calibrate my scales with... but I haven't done so. If you can find aircraft scales (check with your EAA chapter) then by all means... use them! - -- Ross Micheal Mims wrote: > > WARRONFLYS@aol.com wrote: > > > > Be very careful with the bathroom scales.I originally checked my weight with them and was proud as punch. we just got a hold of aircraft scales and now my wife has to loose 135 lbs, and she only weighs 132. double check with accurate scales.

As I said, we have 37 hours on the rear dirve unit. I have made a few changes based upon looking at the dirve shaft. All of this takes time. We do have the new top mounted intake ready to rock and roll when the testing is complete. steve ------------------------------ Date: Mon, 31 Aug 1998 18:30:21 +0000 From: Great Plains Aircraft Subject: Re: KR: Rear drive for VW the bellhousing is the same on the type one and type 4. only diff. is flywheel.

Ross, can we add a line to the bottom of every message that comes from KRNet telling folks how to unsubscribe? Seems like it would save some folks some agony. Personally, if I wanted to unsubscribe, I'd sent a message to majordomo@teleport.com and say the word "unsubscr*be" in the body. I suspect that would do the job, but I'm just guessing...

The mains would apply pressure to the CENTER of the plywood, and then directly to the CENTER of the scale. This is kinda a statics problem, but perhaps you could build a stand/cradle for one scale as long as the portions of the cradle that transfer loads to the scale are over where your feet would be. Using two scales is also better as you would expect each scale to read nearly 1/2 of the total. If they read differently from one another, you should be able to see some problem with your cradle or understand that one of the scales is reading incorrectly. Switching the two scales would let you calibrate your readings to find out. -- Ross Ron Lee wrote: > > Would a 8"x8" or so piece of plywood on ONE scale accomplish the same thing? > > Ron "Bubba Engineer" Lee > > At 07:38 AM 8/21/98 EDT, you wrote: > >Guys, you can solve all the problems associated with bathroom scales by > simply > >going out and buying two more cheap ones.

Oscar & I may get together at the Gathering and hash this out, if you are willing to take what I've got, I can print up a couple and send you one if you send me a KRNET donation to cover our ISP bill and the cost of the CD-ROM media and shipping. Normally I ask for $10.00/yr to cover KRNET, and I think an additoinal $10.00 should cover the costs of the blank CD-ROM and shipping costs.
