Runway cracks growing larger

1 Runway cracks growing larger A work party will be formed this month for repair As you can tell from the photograph below, it s time to get-to-it and start repairing the cracks in our runway. A thorough inspection of our runway during the January meeting showed a large number of cracks that have been developing and getting larger. They will affect the takeoffs and landings of smaller models. The heavy rains we have had recently are penetrating under the runway through the cracks and accelerating the damage. The weeds growing in the cracks are adding to the problem. We are going to have a work party to make repairs to these cracks on Saturday, February 16 th. It is our monthly meeting day and we will have a short meeting and then get to work. We will use our supply of coldpatch asphalt that we obtained from the Gilman Springs Club to fill the cracks. A burner and tamper will be available, so if members could bring shovels, rakes or push-brooms it would really help. The more members that show up, the less time it will take to do the job. RRCC CLUB OFFICERS President: Jeff Szueber Vice-President: Bob Baker Secretary: Rob Evans Treasurer: Larry Roberts Safety Coordinator: Jim Bronowski Field Director: Dale Yaney Newsletter Editor: Jim Bronowski Turbine Flying Director: Berry Hou ALL OFFICERS MAY BE CONTACTED AT: NEXT MEETING SATURDAY Feb 16th 10:00 am crowley field

2 Call to Order: President Jeff Szueber called to order the regular meeting of the Riverside RC Club at 10:13 AM on Saturday, January 26th, 2018 at Crowley Field. Minutes of the Previous Meeting: The meeting minutes of the December 2018 meeting were approved as written and published in the January 2018 Prop Talk newsletter by the members present. Old Business: None New Business: Bill Vaughan (Home) / (Cell) Copper Queen Road in Perris California announced he will have an all-day sale on February 8 th through 10 th. It will take place each day from 10AM on. He is moving and he will have available for sale: RC planes, helicopters, materials, shop tools, machinery, equipment and supplies. Because of age and the recent rains, our runway has developed some major league cracks. Weeds are sprouting up through the cracks making them larger. In order to repair the cracks in a timely manner, we will have a work party after a quick meeting on Saturday, February 16 th to apply asphalt cold-patch material to the cracks. We obtained this patching material from the Gilman Springs club when they lost their field. Our club president is requesting maximum participation of our membership for a few hours work. Please wear old clothes and shoes. It would help if you could bring a rake or shovel. More people, the shorter the time to complete. Our secretary, Larry Roberts announced we only have 34 members signed up so far this year and there are still several people flying at our field who are not members. After discussion, the membership decided that you must have your membership card on your person or in your field box to fly at our field. If you don t recognize someone, ask if they have a RRCC club card. If they don t, they can request to fly as a quest, provided they have a current AMA card. In regards to the above, members of the Menifee RC club have been permission to fly at our field until their field becomes available again somewhere around the first of March. Show and Tell/Presentations: None Raffle: New Merit RC Transmitter and Receiver, 15% Glow Fuel, Hex Key Set, LiPo Battery #8 Glow Plug, CA glue, Spectrum Receiver and Roll of Sandpaper. Meeting Adjourned at 11:30 by Jeff Szueber Minutes Submitted by Jim Bronowski Our previous work party was a while back

3 Malcolm s Musings By Malcolm Oliver Reliving Past Times (Part 2) As an added source of cold air intake for the supercharger. Originally it was a closed molding, so I opened the inlet and cut out the base where it is glued to the fuselage. I then put a hole in the underside of the cowl so that air will be directed over the ESC. The picture below shows the modifications. instrument panel using a JTEC WWII instrument kit. Here are some views of the finished cockpit. There wasn t a means of supporting the seat shell, so I made up the frame to near scale from some Spitfire documents. For the pilot I originally planned on using a Dragon action figure of Squadron Leader Keith Gordon. The detail was fantastic, but he was a little heavy at 10 oz. He s the origin of the name on the plane. In the end I have used a pilot from WarbirdPilots.com. The detail is not quite so good, but he only weighs 7 oz. It also has an integral servo to rotate his head in conjunction with the rudder. You may have seen these at the AMA show, they are neat. Here are some pictures of Keith in The Office Having completed the basic build, I was now able to move on to the fun stuff, making up the cockpit. I used an ESM cockpit kit but it was about an inch too wide. So, I used the basic shell narrowing it down to fit but I had to remake the

4 On all of my airplanes I have been changing the servos over to Graupner HV servos. So, this became another job to do on the Spitfire. I have also replaced the YEP ESC for a Graupner 120- amp OPTO unit so I then have full system telemetry using a Graupner 12 channel Rx with integral gyro. This receiver has effectively 17 channels 12 outputs to servos, a separate input for telemetry and 4 virtual channels for internal functions within the Rx. I ve used 2 of these to control the gyro On/Off and gain. Here is a full list of the channel functions: Ch. Function #1 ESC & power supply #2 LH Aileron #3 LH Elevator #4 Rudder & Pilot Head #5 RH Aileron #6 LH Flap #7 RH Flap #8 RH Elevator #9 Machine Guns #10 LH undercarriage strut #11 RH undercarriage strut #12 Second power supply #13 Telemetry input #14 Gyro On/Off #15 Gyro gain The landing gear is linked to the flaps which in turn have two settings. Half flap (15 deg.) for takeoff and full flap (30 deg.) for landing. As I said before the landing gear is staggered for lowering and retraction, with the left leg leading as per the full-size aircraft. The flaps have a progressive deployment over 2-3 seconds. The elevator servos have to be mixed (100%) within the Rx for the gyro to function but the separate elevator channels enables trimming of each elevator surface. I used my mechanical set up technique, described last month, to equalize the aileron and elevator travel and match the LH & RH flap travel. The two power inputs to the Rx are from the 20 Amp Castle PRO BEC so as to evenly distribute the current across the Rx circuit board in high demand situations. I must admit I just love my Graupner MZ-32 radio system. So that is the status so far. All that remains to be done is to: Complete the radio installation. Fit the undercarriage doors. Finalize the power battery installation. Check out/adjust the CG. Just to wet the appetite here s a complete side view of the plane. One last thing to do now is to buy a 14-watt Karaoke system from Costco so I can play the 633 Squadron overture on my first flight to really relive those past times and bath in the nostalgia! Don t forget that radio check every flight. Malcolm Oliver

5 Here s a great method of cutting out balsa parts for the scratch builder. First, make a templet of the part to be made (fig. 1). In this case it is a fuselage former. Use card stock for the templet. Next, cover the balsa blank with blue masking tape (fig. 2). This aids in making a smooth cut and lubricates the saw blade. Then, use some contact (spray) cement on the back of the templet, place it over the masking tape side of the blank and scroll saw away (fig. 3). The finished piece is lightly sanded around the edges, and there you are with a nice former (fig. 4). Editor It s that time again; time to send in our 2019 dues. Annual fees are due by the end of January. The annual dues are $50 for an Open membership and $10 for those under 18 years of age. Fill out the form above, cut it out and mail it with your dues to Larry s P.O. Box. A check is the preferred method of payment as it makes Larry s job so much easier. Again, if you have a hardship let Larry know. He can help you work out a payment option. Just to let you know, Larry doesn't usually cash the checks until he has number of them.
