Re: KR> exhaust system - nothing left but the tailpipe!
on the exhaust subject, my picture of Ken Rand original shows short stub pipes. Obviously these take up the least real estate, and get more heat out of the cowl. assuming backpressure needs can be addressed with baffles (?) whats the downside? ___ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.

Re: KR> Mole tail?
I think this lightest aircraft is not a KR. It looks to me like a clean sheet project and I'd like to know more about it. As to reinventing the KR, even ken rand "reinvented" the plane in a number of way including creating the KR2, and other major and minor developments. many see experimental aircraft as an opportunity to learn, as they are described in the regs, and so we try things. You make tradeoffs. you want less cost, you may add weight, or vice versa. I am trying to make my project as faithful to the first KR1 as possible but it will need to be a trigear because thats what i know how to land best and its safer. a good example of worthwhile reinventing the wheel. also, the original had a short nose due to the c-channel engine mounting system right against the firewall. however that necessitated the belt driven magneto which is why there is a shelf at the top of f/w. do you really want a belt driven mag? that was resolved by moving the engine forward onto a traditional tubular mount. I may have other options including electronic ignition. more reinventing. maybe I will never even build this thing to completion. but as long as I am trying, reinventing the 46 year old(!) design will be a part of it to some extent.

Re: KR> Liquid cooled VW
actually, the opposite may be true. I just went through this with an antique engine I am working with. my machinist had installed customer provided custom aluminum pistons in a big very old liquid cooled car engine. the clearances were too tight and they seized. I was considering replacing my cast iron piston with aluminum and was advised by another machinist who works with them to allow extra clearance at the top for piston expansion. he mentioned 2 thousanths extra above the rings. he made a piston once for a similar engine that started getting tight when hot and that fixed it. this is from a guy who makes his own crankshafts from steel plate!

KR> rearward engine placement
hi all, I am hoping to replicate the first KR1. one major asthetic change seems to be from the engine in that was mounted to two alum channels at the firewall, allowing for short nose. looks like about a 5" space from rear case to fw. the magneto was belt driven and mounted high and I am sure this is why that "shelf" exists at the firewall. I have seen electronic ignition which populates the distributor hole and is low profile, and think that would eliminate the magneto need. a starter I think could go there at that shelf anyway, just tossing that out there to try and keep the nose as short as the original. since todays VW engines are bigger displacement than ken's original which I believe was quite smakll less than 1500cc IIRC, but are they longer now too, or same case dimension? suggestions for ignition would be appreciated as well. thanks as always for any advice cp ___ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.

Re: KR> KR 1 project
ok no retracts, duh, shoulda gone back and looked. ideally I'd like to build a tri-retract, original size KR1, with engine back against the firewall as original, and with a normalizing turbocharger. the main retracts are easy. the nose can swing back halfway into a center pocket (I think). as to a small normalizing turbocharger, tight squeeze and heat issues. which is why it would most likely be added later, in a phase two. point being, I am happy to see some added complexity is possible with enough thought and skill! ___ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.

Re: KR> Pitch sensitivity
> Could you go into further detail about "how" it flew better with a forward > CG than an aft CG? Sure, the plane under normal conditions (no baggage) would require significant up trim to unload the stick, and when pulling power, would drop the nose unless you held onto the stick. "Lawn dart"is a description used more than once. Conversely, with plenty of stuff in the baggage compartment (at or near aft CG limit), the plane seemed to "float" in balance and handled much better and was faster to boot. A pure dream to fly. This was discussed often. It was considered by some to be good practice to ignore the front half of the CG envelope. It is possible that the CG envelope was shifted a bit forward than it should have been and in fact I spoke with someone in good authority that the aft limit was quite conservative and flying AT the published aft limit would in fact produce good results, and it did. > See http://www.n56ml.com/wb/index.html for more on the KR aft CG, which I'm > pretty sure is common to most aircraft.
