KR> Wednesday KR2 flight
KRnetHeads, Here's a quick report on a flight I made down to my father's grass strip yesterday, which is 80'x3600', and not a bad place to fly out of. I'm sure I didn't use half of it, either landing or taking off. There are trees on one end, and it's uphill toward the trees, so it's pretty much a one-way strip that works quite well. On the trip down I was burning 3.4 gph while doing 145mph True AirSpeed at 7500' on a nearly "standard" day. That's 43mpg, and getting there pretty quick. TAS is irrespective of head or tailwind, so this is a repeatable result. The trip was completely uneventful otherwise, except the hazy skies allowed me to wander all over the place. I need an autopilot to keep me on course and at altitude! See enclosed photo for a nice view of the grass strip, with N891JF ready to go. The strip is situated between three lakes. See http://www.n56ml.com/flights/jan2006farm/ for a better view of that. -- Mark Langford ML at N56ML.com http://www.n56ml.com -- next part -- A non-text attachment was scrubbed...

KR> LSA Operation
Quick answer on Google says: "The maximum penalty for flying in command as a pilot without being certified is up to three years in prison and a $250,000 fine."

Why does a ramp check scare you? Normally they just ask to see your license and aircraft registration/paperwork. No big deal. Visual inspection of the plane from the outside only as they are not supposed to be able to enter your plane. The odds of it happening are a million to one. Treat it as a nice check with someone who just might like to look at your neat toy.. Above all, be nice and smile!

KR> Wing Extensions
There's published numbers and then there's reality. If the published empty weight, range and cruise numbers are anything to go by, the published stall speed might be suspect. Having said that, there are several KRs on the recreational register here in Oz, and that requires a stall no greater than 45 kts (51.8 mph) in the landing configuration. So it can be done without getting too adventurous with mods. Cheers, Tony On 17 March 2016 at 13:50, Chris Prata via KRnet wrote: > this is interesting.

KR> LSA Operation
Sid, What prompted the ramp check This is the only thing that scares me about flying...

Sid Wood
KR> LSA Operation
My hangar partner has a Pulsar XP with a 80 hp Rotex engine. With only him onboard he cruises at 141 Kts and 4600 RPM. He found that the plane will cruise at 120 Kts with 4200 RPM. He wrote a letter to the Washington FSDO (the local FAA cognizant office) reporting those parameters and stated his LSA intentions. He wanted to operate the aircraft as a LSA and not renew his medical. He never got a reply to his letter for several months. So, he called the FSDO; they said his letter was on file and not to expect any reply. The inspector also told him that the aircraft is registered as experimental and he could make any declaration regarding the aircraft. He made no aircraft log book entry and did not install any placards regarding the LSA operation. After operating for four years without a medical, he has had one ramp check without any further problem. Your results may vary. Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA

KR> Wing Extensions
this is interesting. LSA specs say 51MPH max stall speed without using flaps. I looked up the specs, and the KR1 easily meets the stall speed specs at 45MPH stall. (so with fixed gear, modest power and and a climb prop, I will be all set to fly under LSA rule) The KR2 is published as 52 MPH stall. Thats only one MPH. Couldnt you get there with VG's? Also, I dont see flaps mentioned one way or the other on the KR2 perf spec. Maybe thats the catch? > To: krnet at list.krnet.org > Date: Wed, 16 Mar 2016 20:56:18 -0500 > Subject: Re: KR> Wing Extensions > From: krnet at list.krnet.org > CC: ml at n56ml.com > > > Steve Goosic wrote: > > >>Since my wings are already built > (RAF48), do I extend both wing spars or is it possible to add additional > foam to the existing wing end and shape to form?
