The July 18th KCRC club meeting, held at the Charles Reed Memorial flying site, was called to order by Pres-ident Duane Hulen at 7:00 P.M. The other officers present were Treasurer Bob Deskins and Secretary John Midgorden. There were 34 members present including two new members, Sara Koch-Nelson and Buck Skidmore. Visitor Mark Engelman was also wel-comed present. OFFICER REPORTS President Duane Hulen asked for a motion to approve the June minutes as printed in the newsletter. Motion received and the minutes were approved. Duane shared his NATS Quickie experience. He won the 424 race and came in fourth in the fast 426 class were there were 62 entrees The weather was great and he brought all his racing machines home. Duane explained it was time to make the Swap’N’ Shop down payment. Treasurer Bob Deskins indicat-ed that the down payment last year was made in Au-gust. He will be taking care of this payment to John Knox next month. Duane also reminded everyone that nominations will be received for the offices of President and Vice-pres-ident at the August Club meeting. Bob Deskins and John Midgorden have indicated their willingness to serve again next year. Vice-President Jesse Casteel was absent due to his wife’s illness. Secretary John noted that the Club’s 2018 membership now stands at 66, including the 2 new members who signed up during the meeting. John also shared that Barb Carey had emailed him indicating she is still negotiating with the gal for new Club hats. Treasurer Bob shared the details of the Clubs June income and expenses. He also indicated that he has received $845 for the Jim Koch bench. Park Liaison Jimmy Cianciolo announced that he has given the Park $1,000 for the Jim Koch Memorial Bench. The price includes the concrete pad to set in on. The loca-tion for the bench is yet to be decided. The Park will also provide a plaque but the exact wording is still too be decided.

OLD BUSINESS Pattern Contest: John Ford, CD, referred to his written report n the July Contacts. Several of the 14 pilots also competed in at the NATS Pattern con-test. John indicated that there were other Pattern flyers who might have attended the KCRC con-test, but because os time and distance didn’t come since they were also going to attend the NATS. Bob Deskins shared that he had sent the Park $55 to cover the daily Park Use Fee for 11 of the Pat-tern Contest contestants who were from out-of-town. NMAD: Susan Calvin reported that she had regis-tered KCRC as a participating AMA Club for the National Model Aviation Day on August 11. She also offered posters to anyone who might have a place to display one. She brought up the idea of a silent auction (as she has done before) but there didn’t seem to be any interest. It was felt that do-nations from pilots and spectators would probably be adequate. The charity this year will be the Children’s Mercy Hospitals in the Greater Kansas City area. Warbird Fun Fly: Susan shared she has a poster developed for the Warbird event, but is waiting until after the NMAD event to begin publicizing in earnest.

NEW BUSINESS Joe Carollo apologized for his not being able to help with the drinks. Between work and family he just doesn’t have the time needed to devote in helping the Club in this way. Tom Safley ask if anyone is interested in a tour of the Downtown Airport WheelerControl Tower. Tom as a neighbor who is willing to take a group on a tour of the Tower. Either let Tom know if you are interested or watch for an announcement in the newsletter. Tom is working on a date.lk Sara Koch-Nelson wondered if she could try to sell some of her Dad’s model stuff at a future Club meeting at the EAA Hanger. Rick Hobbs volunteered to help Sara make a list of items that KCRC Club members might be interested in. Then club members could contact Sara for possi-ble sales.

A number of items were raffled off and a Dragon Lady kit from Neil McCumber brought in $40 to the Club treasury. Respectfully submitted, John Midgorden, Secretary

SAFETY BRIEFING SUSAN CALVIN, SAFETY OFFICERWhen I was studying aviation safety in college I had occasion to review a lot of aviation acci-dents. I always anticipated reading about some-thing new and unusual. Over time I discovered that there was actually very little new under the sun. It seems that the more one studies accidents the more one begins to see patterns repeat them-selves. One example is stall-spin accidents. These accidents are so similar in their presenta-tion that often only the N number distinguishes one accident from another among specific air-craft types. An example is single engine Cessna’s. They all seem to bend and distort the same way. So, when looking at multiple photos, it’s often very difficult to tell one stall-spin accident from another, (unless you can see the N numbers). Sometimes repetitive accident scenarios are based in the habits of the people involved. Acci-dents involving propellers fall into this category. People too often become so comfortable, even complacent, around propellers that you have to wonder, “What were they thinking.” I remember one accident report wherein a C-130 crew mem-ber had the habit of rushing out the forward crew door during hot turnarounds and running toward the tail of the airplane to help the ground crew load and unload cargo. The C-130’s props were so high that he could run under them with-out making contact. Many times he was warned about this behavior, but shrugged off the warn-ings. Then, one day, he was assigned to fly aboard a C-123. (The C-123 is very similar in configuration to a C-130, only smaller). The props on this plane are much closer to the ground. You can use your imagination to develop a mental picture of what happened next. The reaction of most people to such accidents is to sympathize with the victim. Perhaps because I’ve read so many such accident reports I’ve become a little callous. Now, my first response is to con-sider the damage to the airplane. Propellers, like most aircraft parts, are expensive don’t you know. And it’s my tax dollars that pay for them. The reason I brought up this propeller accident is that I just read about a fellow modeler who had an encounter of the propeller kind. You can

read about his experience in the August issue of Model Aviation. This fellow got careless, perhaps even a little complacent, around his model and the prop bit him, hard. What I find most enlight-ening about his accident is the x-ray of his hand that shows a slice that the prop took out of one of his finger bones. Over the years I’ve read about other such encounters/accidents, but the injuries were mostly to soft tissue. And a lot of those accidents involved what we would now consider small glow engines. Today the planes are bigger, and so are the engines. Now, consider one more detail about this specific accident. It was caused by an electric motor. Most of us would consider such powerplants somewhat small compared to the much larger glow/gas en-gines now in vogue. And yet, look at the damage it caused to this fellow. Propeller accidents, like other accidents, too of-ten follow a repetitive pattern. Again, there’s rarely anything new under the sun. A very im-portant lesson to glean from accidents of any cause, not just propellers, is that no one can af-ford to allow familiarity with any airplane com-ponent to take effect. For whatever reason, de-sign flaw or centuries of conditioning, it’s easy for each of us to become complacent/ inatten-tive/careless, (use whatever adjective applies to you) around machinery, especially airplanes. Constant vigilance, critical thinking, and never ending attention to detail are the only things that stand between any of us and a serious injury. By way of cliché, keep your head on a swivel, pay attention, watch where you step, trust but verify, plan ahead, etc. It’s a jungle out there, and the accident bastards are out to get us all. 1.

Last summer I saw a set of plans in the British model magazine "RCM&E" for a retro-looking sport plane called a "Tiger 72". (Every month they have full size plans for a plane.) I decided this was one I had to build! So, I removed the plans and took them up to FedEx to have them copied for some plans to cut up for the smaller parts and for pin-ning to a build board without ruining the originals. This was to be my winter project; A nice-looking plane with a symmetrical airfoil, 72" wingspan, and electric-power. I normally use a 1" thick insulation foam board lying on a coffee table for building parts of any size like wings, fuse-lage sides, and horizontal tail surfaces. It allows me to use T-pins, and sometimes small weights to hold balsa pieces

in place pretty well, and to easily move the work board to another room if need be. I like to start building with the tail surfaces first as they usually are the easiest and can be completed fairly quickly. The fuse-lage comes next so I can get a good feel for the size and really get in-volved with the building

process. Lastly, the wings. I think the wings are always the most time consuming to build and take the most room to store before cover-ing! The plans are very good but it seems there's always something in the plans I find to do differently and these were no exception. Although they call for elec-tric power, I believe the de-signer had previous experi-ence making plans for nitro planes because this one seemed over-built for a plane with smooth electric power. For example, one change I made was to use balsa sheet in

place of plywood for the fuselage sides, and substituting

some parts as not all materials called out in the plans are available on this side of the ocean. The motor and speed control needed to be changed for the same reason. Also, instead of making the engine cowling with balsa pieces, I made it out of fiberglass. I won't go into the actual building process as it was pret-ty straight-forward using CA glue for the most part and a

little epoxy here and there. How-ever, I'll go into one part of the building that wasn't in the plans. As I have done for a few planes before, I used 1" thick pink insulat-ing foam board glued together and cut/sanded to shape for the cowl-ing. Then it's fiber-glassed using some 3.8 oz. bi-directional glass

and a lightweight "deck" glass, using a surfacing epoxy as it is somewhat thinner than the normal structural epoxy and wets out the fiberglass better. The foam is roughly cut out from the inside and the remaining foam is melted out with acetone on a rag. I have used gasoline be-fore and while it works well, this was in the winter and it was too cold outside for me. Sanding the outside to smooth it up is the last part and takes the most

time. Priming and painting completes the cowling. I used "Ultracote" for the airframe covering and I prefer it over "Monocote" due to its easier workability, for me, at least.

I decided to use an "E Flite Power 60" motor and a 6s 4000 ma 25c LiPo battery and a "Castle Cre-ations" 90 A. ESC (speed control), with a 15x7 wood prop for electrics. I knew from previous experience

with this setup that I would have approximately 11 lbs. thrust at full power. With a ready-to-fly weight under 9 lbs., the performance should be pretty good. I did have to add 1 1/2 oz. to the tail to get the CG in the middle of the range as the only place for the battery is pretty far forward. One thing I like to do is use an air scope to cool the ESC and as I've done before, I use half of a "McDonalds" ice cream spoon. Works perfectly! The main landing gear was made from a 1 1/2" x 1/8" 6061 bar stock from "Air Parts" in Merriam, Ks. and lightweight balloon tire wheels from "Sig". So, on to the flying. The first flight was with a 5-cell bat-tery and the performance was still surprisingly energenic. Using the as-designed 6-cell battery, the performance was great thanks to the motor/battery combo, giving sustained vertical climb if desired. With full control surface deflec-tion, roll rates, etc. are pretty quick so I used dual rates to tone down the action, and I added in 35% expo to soften the stick. Even with that, the performance is still very

quick. Gliding could be improved as it tends to drop quickly when the power is pulled off, but down in ground effect, just a foot or so above the ground, it floats along a bit before dropping down. I need to learn to land better as so far, I usually bounce some before actually rolling out. Takeoff and landing rolls are pleasingly straight needing very little correction, even on the asphalt. It handles very nice on the ground for a tail-dragger. Operating in the grass makes it especially easy. I'm still exploring the flight envelope and I see that it'll give a lot of performance when called for. Half-throttle flying is really nice for just tooling around. In actual use with the 4000 ma batteries, 8 minute flights leave the batteries under half charge and moderately warm. The "Tiger" seems to want a higher power setting than my other planes for steady flights, plus, I end up using more power for the aerobatics. So far, I'm very pleased with how the "Tiger 72" turned out and I've had quite a few compliments on the appear-ance, too. This has been an interesting build and I'm glad I chose this design.
