KR> brake problem at Barnwell
I sold my KR because of brake problems. Not because it was not a good airplane but because of the inferior axles, brakes, and tires. and I have a Lancair. I enjoyed flying the KR because it was so economical and fun. I would upgrade to a good set of axles and brakes if I was going to keep the plane From: Mark Langford via KRnet To: 'KRnet' Sent: Monday, November 10, 2014 12:14 PM Subject: Re: KR> brake problem at Barnwell Larry Bell wrote: >>You have given us some outstanding ideas on building, so looking at those brakes surprises me.

They are both good programs.

KR> brake problem at Barnwell
Mark, You have given us some outstanding ideas on building, so looking at those brakes surprises me. The disks look very thin which wouldn't give much heat transfer. I got a set that I think is Matco with nice thick disks and good pads but they have ball bearings on both sides versus tapered on one side for side load . They came off a retractable setup. I'm wondering if that is any good. I have thought a lot about backup braking but don't have any idea how.

KR> Stick imbalance
Jeff, Thanks again for your reply. I found even better photos of your wedges on the 2004 Gathering page. http://krnet.org/mvn2004/040929462.jpg That's when we met! Anyway the simple tab I added seems to be working. Next up is an armrest. I need one... Thanks again for your help. John Bouyea N5391M/ KR2 OR81/ Hillsboro, OR -Original Message- From: KRnet [mailto:krnet-bounces at list.krnet.org] On Behalf Of Jeff Scott via KRnet Sent: Friday, November 07, 2014 8:19 PM To: krnet Subject: Re: KR> Stick imbalance Congratulations John! If your W is correct, the most likely culprit is going to be the incidence of the horizontal stab. I had the same issue (except mine wanted to dive at the ground). I flew for several years with some rather large trim wedges glued to the trailing edge of the elevator to correct the stick pressures and allow my trim tab to do it's job. That was eventually fixed when I built the new tail and corrected the incidence. If you look at the air to air photos of my KR from the 2002 Red Oak Gathering, the photo of me rolling away from the photo plane (over half way down the page) shows the wedges on the bottom of the elevator. Congrats again.
