I am sure some of you braved the cold weather and went to the Icicle Fly-In. I personally wimped out and stayed home in my warm house. I heard Steve Engleman was there before the ranger and had a fire so big he thought it might catch the wind sock on fire. For those of you that were there hopefully you can share your experiences at the meeting. Next up is the Swap N Shop. Table registrations are going well. Please forward any fliers that you have to people in your to get the word out. Hopefully those that have helped in the past, worker wise will be available to help again. We will discuss this more at the meeting. That's about it for this month, short and sweet!

2 CONTACTS PAGE 2 FINDING THE CG OF A FLYING WING (UPDATE) Here is an update and clarification from my friend Allan Brown in California regarding the article in last month s Contacts relating to finding the CG of a flying wing. Refer to last December s issue for the previous article and drawing. You talk about a simple flying wing, which to me may infer a tailless airplane. This approach is clearly appropriate to any wing, noting that for a conventional tailed airplane the c.g. could be started at 25% of the mean aerodynamic chord as you say, but for a tailless airplane you might want to start at 12 to 15% back on the mean aerodynamic chord. If this wing were on a canard type airplane, it's a more complicated story, and the c.g. might typically be about 15% chord ahead of the wing leading edge, but very dependent on forward lifting surface area, relative height (determines downwash), and angle of incidence. KCRC Finances Those of you with have received Bob Deskins s 2017 summary report of the Club s finances. Bob will make his report of last year s finances at the January meeting. If you have questions about the report he will be more than happy to explain and clarify the data. KCRC is fortunate to have Bob as our Treasurer. As most of you probably know he is a retired CPA. Next time you see Bob express your gratitude for his stewardship of our finances. YOUR 2018 OFFICERS Duane Hulen, President (816) drhulen@sbcglobal.net Jesse Casteel, Vice-Pres.

3 CONTACTS PAGE 3 MINUTES OF THE DECEMBER CLUB MEETING The December 20 th KCRC club meeting, held at the EAA Hanger at the Lee s Summit Airport, was called to order by President Duane Hulen at 7:00 P.M. The other officers present were Vicepresident Jesse Casteel, Treasurer Bob Deskins, and Secretary John Midgorden. Altogether there were 23 members present. OFFICER REPORTS President Duane asked for the approval of the November minutes as printed in the newsletter. The minutes were approved with no corrections. He also noted the recent Board of Director s meeting that he will report on later in the meeting. Although he is always concerned about the Swap N Shop table registrations he noted that he has received 42 so far. He was asked how many we normally have and he reported around 120. He told the members that he had deposited $1,100 from the table rentals. Vice-president Jesse Casteel had no report. Secretary John noted that prior to tonight s meeting only 18 people had renewed thier membership. John also brought attention to the fact that the FAA requirement has been reinstated by the Congress and signed my the President. Therefore, we will continue to be required to register with the FAA and to carry our FAA number on our aircraft if they weight between 0.55 and 55 pounds. The AMA will be following up with additional information. He also apologized if he had missed anyone in the December Newsletter of those who make KCRC Great. Treasurer Bob Deskins shared an income and expense report for the month of November. He also explained that with the help of Jimmy Cianciolo they had cashed in the Club s small CD because of the danger of running out of money in the checking account. Bob announced that he will be publish a year-end report of all income and receipts for OLD BUSINESS Duane reported on the Board meeting held on December 6 th. At the meeting the events for 2018 were decided upon. The Board also discussed the runway situation, training nights and the possibility of having Club Days this coming summer. Mike Ryken reported that his son-in-law is going to look at the runway and possibly give us a quote for putting down a sealer coat. Duane suggested that Club Days will be tried again this summer on the Saturdays following the Club Meetings at the field. Mike Ryken also explained how he happened to get the Air Force Colonel as our guest speaker at the March Appreciation Dinner. He is a former B-2 Pilot. Duane explained that the past summer s training night was not very successful and that this coming year training will be done by appointment. John Midgorden will post a list of instructors on the field bulletin board with their phone numbers. NEW BUSINESS Duane sent a card around for Jim Koch for members to sign. John will see that it gets mailed to Jim. Duane also reminded everyone of the New Years Day Icicle Fun Fly and encouraged members to bring some chili for lunch. PROGRAM Jesse Casteel provided a DVD on the history of the original Los Angles airport that is now the Van Nuys airport in the San Fernando Valley. Respectively submitted John Midgorden, Secretary

4 CONTACTS PAGE 4 SAFETY BRIEFING When I was very young (about 100 years ago) I could spend hours listening to my grandparents tell stories about Christmas. These stories usually involved dealing with all the snow they had, and how they had to ski to school in snow so deep that only the tops of fence posts could be seen. At the time, as memory serves, we still had snow for Christmas, only not as deep. Now it seems that all we get is a dusting in December and that any severe weather usually occurs in February and March. And instead of deep snows we tend to get drizzle and ice. Perhaps, if I live long enough, the weather patterns will change and we can all see significant snow for Christmas. I mention this for two reasons. First, I still have a lot of Christmas decorations to take down and store for next year. Second, we are coming into a season when we will have to deal with slick, icy road conditions. And sometimes we will encounter cold, standing water on the roadways. Perhaps, like me, some of you will be undecorating outdoor displays. That may mean getting up on your roof to take down lights and other displays. I have a lot of them, including a Santa sleigh and three Reindeer mounted on special platforms. That means a lot of time climbing a ladder and then transitioning to my roof. I learned long ago that the best way to do this is to always maintain three points of contact with everything I m climbing on. And, by way of prior planning, I m always ready to fall flat on my roof if my feet start slipping. That greatly increases the area of surface contact which has the effect of stopping my slide. It s sort of like the best stopping action in our cars is dependent on having the greatest area of contact between our tires and the road surface. I m always thinking about such things, perhaps because of my paranoia when it comes to safety. As I ve said SUSAN CALVIN, SAFETY OFFICER before, Prior Planning Prevents Poor Performance. We all like to daydream, so why not daydream about safety scenarios? Now, concerning the upcoming seasonal weather and our cars, this seems a good time to mention a couple of things. One is coefficient of friction and slick road surfaces. Coefficient of friction relates to how firmly our tires grip the surface and plays a significant part in equations related to stopping distance. The coefficient of friction is different for each type of road surface (concrete, asphalt, etc.) but remains within a close range for most prepared road surfaces. The thing we need to remember is that the coefficient of friction rapidly approaches zero on ice. That means the only thing that will likely be stopping you will be the fixed object you slide in to. Forewarned is forearmed here. Finally, and this applies to any season, if we encounter standing water we are in danger of hydroplaning. A lot is said about this on the daily weather reports we watch, and it appears as a question on some driver s written exams. But no one ever explains the dynamics of hydroplaning. So, I m going to give you a little formula you can use. Two things are required to get into hydroplaning; the water depth must exceed the tread depth of our tires, and our speed must be equal to, or greater than, nine times the square root of our tire pressure. Don t panic, it s a simple problem. As an example, if our tire pressure is 36psi (a common pressure) the square root of 36 is 6. Nine times 6(psi) is 54. Therefore, (in this example), if our speed is less than 54(mph) and our tread depth is sufficient we will not hydroplane. A little practice with these numbers will help you figure out your best speed to avoid hydroplaning. (Have fun).

6 CONTACTS PAGE 6 How about this Circa 1980s photo of Darwin Ulledahl presenting Tom Cook with the Duck-ted Fan Award after he won the Scale Masters event in California with his awesome McDonald F-4 with two K&B ducted fan engines. As I remember the story Tom competed for three days at the Masters Contest without a flame out in either of his engines. Bob Violet was also competing with his Douglas A-4 with one K&B ducted fan, but had flame out after flame out. Mr. Brodbeck of K&B came up to Tom after the contest and ask him what he had done to his engines to make them run so good. Tom s reply, I installed OS 90 carburetors. Here is a group of KCRCers who went to Montezuma, IA to fly in a SIG event. This was when everyone had to fly a SIG model. However these enterprising KCRC modelers didn t like the SIG Chipmunk kits that had a profile fuselage inside ABS plastic sides to make the fuselage look three dimensional. The KCRC team made a mold from a SIG kit and made fiberglass fuselages for their Chipmunks. Evidently the SIG folks didn t like it one bit. Can you pick out any in this photo who are still active in the KCRC Club? Here is an aerial photo of the KCRC Field that Jim Koch took while flying his full-scale Cub. Note that this was before the shelter house and current flying stations were constructed. Although not obvious in this photo, the runway was shorter then than it is now.
