However, this afternoon about 2:00 the parking lot was more than half full. What a contrast. Didn t Yogi say, nobody goes to that restaurant anymore, It s too crowded. I think everyone thought on such a beautiful evening, it would be too crowded. The KU team was at the field today with their experimental Aeroworks Yak 54. Darrel Cordle was the pilot in waiting, as they worked to set up all their electronic gadgetry. Darrel said the gold box in the center of the fuse represented 10 bills, if you know what I mean. The field was still pretty wet from all the Friday showers that passed through. So, while he waited, Darrell flew his own Golberg Yak 54 with Saito 1.80 power. 1
Careful there Darrell. Now if you think this is a lot of water, wait until I show you pics from last month I believe they are ready to go now. My, look at the thickness of that turf. Here is the KU aircraft followed by a photo of the gold (black) box. Now that s an interesting work posture, standing on the prep table. Spectators in the backround. Hey, you want to see some sunset photos? With a little water sprinkled in. Take a look at these babys. The gold box: $10,000? 2
Now all this water didn t just happen. It all started on club day last month. I was on my way to the field after stopping at home after the club meeting to get an airplane. Most of you guys were already at the field. Little did I know, but 2 things were happening. One storm clouds were a brewing, and number two, Phil Abbadessa was on his way to the hospital after engaging the prop on Greg Kloeppers Mariner float plane. When I arrived, this is what I was met by. Some of us are having a hard time finding work in the construction business, but Supancic must be doing all right. Have you seen his new RC rig. See below Guys were packing it in to beat the storm. How about that new car he bought Timber? Whoa, look at that L-39!! Below John Bowman is starting to dismantle his aircraft. John got caught by the winds and rain, but made it to the storage building with the help of the guys. Hey speaking of big stuff. Did you see that full scale model Bird-dog the AMA built for Oshkosh. Rubber Powered?? 3
Patrick loses float plane Unfortunately, Patrick Deuser crashed his Neptune style float plane at family night last month. Just a week before the float fly at Lake Bismarck. Did I hear someone say, I thought the flazzenburg valve was too loose, it was whistling all the way down the runway.. Someone else said, it s a mistake to take a scale model out to fly while you still like it. Finally, someone else asked, would you build another one the exact same way? Absolutely, he said, I judge the fun level of a plane by using the hand shake test. After the flight, if your hand ain t shaking, the plane was no fun. Let s just say that airplane passed the test. Elkins teaching grandson Jayhawk Float Fly I believe this was the 5 th or 6 th annual float fly of the Jayhawk Model Masters. I don t know about you, but I was really looking forward to this one. We ended up with 16 registered pilots, and probably 25-30 Float Planes. One pilot came all the way from Wichita, however, he was also the pilot that initiated a mid-air. Fortunately, it was his aircraft that was lost and not the guy he hit. The weather was great all day with a south breeze of about 10 mph. Speaking of Bill Elkins and his grandson. It was he who pulled Bill s winning raffle ticket from basket. Bill won the 80 fabric covered Great Planes Cub with floats, a $300 value. The highlight of the day was finally getting to see the huge 90+ inch Supancic Gee Bee on floats and the water at last. Did I hear that Bill Elkins was teaching his grandson to fly RC. I understand that he has him on the simulator, and plans to have him flying in the 2 weeks that he is going to be here. Now we all know what it means to Elkinize an aircraft, but what would you call it when the grandson of an Elkins elkinizes his aircraft. The Grand Elkinize?? Looking good so far? 4
Still looking good? As you can see, the motor mount and engine broke clean of fuel lines and throttle rod and implanted itself in the front deck of the aircraft. We could have witnessed one of those Nate Ericson free flying engines if the prop didn t find some balsa to carve up. Or the engine might have been claimed by the deep waters of Lake Bismarck. All s well that ends well. Did Yogi say that too? Woops-a-daisey there George Jones Woops! What happened here? Elkins family at work! Well you see, it went something like this.. The aircraft lifted off just fine, but the wind caused it to drift out of sight to the left. And when it came back into sight it was headed for the water. Another interesting happening was the dead stick landing of Bill Elkins Mariner. Someone yelled on final, the engine fell off. But it did seem to have a perfect CG glide as if the engine was still there. Well the engine was still there, kind of! Another stik style float plane. 5
This Canadair CL-415 is about to experience a very hard one engine out landing. Damage was minimal considering the spinning smack to the water. June 19 Club Meeting We had about 25 people at the meeting including new member Josh Smith. Josh has been getting instruction from Darrel Cordle and I believe has already soloed his aircraft. Josh also benefited from his new membership by winning the raffle prize this month, an 80 Top Flite 182. See below Nice Neptune style aircraft Some sad news I just heard that Bob Stocksen lost his 150 Lazer 200 last night at the field. It appeared that the aircraft experienced a slow speed stall, and I m told that it is probably a total loss. I loved watching Bob fly this baby with it s killer smoke system and all. Sorry Bob for the loss. 2008 below: Jerry Foree gave the treasurer s report indicating that our current net worth is $5234.20. This was followed by the Safety report. Kent Kummer was on hand for this report and he warned us about heat related illness s. Be sure and hydrate yourself before going out in the heat and take water or Gatoraid Propellor safety was again addressed. A discussion ensued regarding flying an aircraft directly at the pits and then aggressively pulling elevator. This will not be tolerated. The following old business was either deferred or updated: Build-a-plane Hard Surface Humane Society as charity Sign for front parking lot Memorial repair Handicap parking signs New business was as follows Webcam study Permanent electrical power PA System repair 6
The Gal-O-Fuel was won by Robert Sharp and Gary Allcorn won a $25 discount coupon to Dyanamic Balsa. The coupon was donated by Mike Weinsaft. Show & Tell KC Moore had the only show & tell with the E-Flite Blade MCX2 Helicopter. This is a twin blade micro Heli that runs on a 2.4 ghz system, and uses the same battery as the Parkzone P-51. Understanding Deans Connectors By Phil Laperriere Now it was time to solder the Deans-style connector onto the battery leads and the speed controller. One month ago I didn t have the foggiest idea what a Deans Connector was. Now, here I am buying them at the Prop Shop and trying to tie them into my power system. I read the instructions on the back of the pouch that the connector set came in, and the instructions told me to tin (pre-apply solder) to the wires and connectors then touch the two together, add a little heat and you should have a good bond, ready for shrink tubing right? Wrong! By the time I was able to melt the solder on the connector, the tab had melted the outside of the connector, allowing the tab to move out of position. Also, it seemed like an extended period of time before the solder would cool enough for handling due to heat being retained in the connector body. I also found that the bond between the wire and the tab was not very strong and was easily pulled free. After a long frustrating struggle, I was successful at getting one set of connectors soldered in place. However, when I tried to plug the two connectors together, the tabs were so far out of alignment due to the melting of the outside shell, they simply would not go together. After ruining three or four pairs of connectors, I finally stumbled upon a solution. I found if I first plugged a set of connectors together and afterward started the tinning/soldering process. I had much better success at a well aligned connector. I also noted that the solder joint seemed to cool quickly along with the tab alignment remaining intact and showing great bond to the wire. Having the connector plugged together also gave me enough material to hold in a vise for soldering. A couple of other observations I want to point out that seem to make sense to me after going through the process of assembly are as follows: Lightly sand the tab where you intend to solder, giving the material an opportunity for tooth. Always assemble the female portion of the connector to the battery side. By doing this, you won t be as likely to inadvertently short out your battery because the terminals are not exposed. Maintain a standard for your connectors for positive versus negative. Doing this, you ll finally have flexibility for switching between batteries and speed controllers. Typically, Deans Connectors recommend the wide end be utilized as the positive side. Have an extra set of connectors available that are used only for the assembly process. This way you won t power up the speed controller when doing assembly. Also, if you do utilize a set only for assembly, be sure to put the shrink tube over the exposed terminals to minimize the risk of a short. Use shrink tube over your solder joints. Shrink tubes serve two purposes. First and foremost, it acts as an insulator, minimizing the potential for a short. Second, it adds strength to the wire just behind the solder joint reducing the opportunity for wire fatigue. 7
