Adjusting Your Needle Valve (or How to Ruin an Engine Real Fast) by Jerry Kelly: “Now raise the nose of the airplane to a vertical position. The motor should speed up because it is drawing fuel from several inches lower than when in the normal position.”


Bench Running a New Engine by Jerry Kelly:The worst injuries I have seen with model engines involved bench running. Make sure that the bench is sturdy, the mount cannot come loose, and the floor area is clear (so you can run if something starts to come loose). This will sound silly, but do not grab for the motor if it starts to move or fall. It is unlikely that the motor could hurt itself if it came off the mount.”


Care and Feeding of Nicad Batteries by Jerry Kelly: “Transmitter batteries in good shape can be relied upon to be very consistent in the time of operation because the load (drain) is constant.”


Dead Stick! by Jerry Kelly: “But whatever you do, DON’T stop flying the airplane. Your situation may look bleak, but continue to work the controls. I’ve seen too many cases where a pilot just shrugs his shoulders after an engine kills. That just guarantees a crash.”


Getting Started in Radio Control by Sig Manufacturing: “The initial investment might seem high to the newcomer, but once you are established with a model, engine, and radio, the costs stabilize and can be as much or as little as you want to spend.”


Negative Incidence by Jerry Kelly: “Incidence is the angle formed by a line

through the leading edge and the trailing edge of the wing and a similar line through the horizontal stab and elevator (at neutral). When the line through the wing points down, in relation to the stab line, it is called “negative incidence” or a lifting tail.”


Neutral Rudder – the Final Test by Jerry Kelly: ” During your pre-flight, you should do your best to have the rudder in a “neutral” position: No left, no right.”


On Glow Plugs and Ni-Starters by Jeff Junker: “You’ve had five flights and get ready for a sixth. You go to crank it up and nothing happens. First thought goes to the glow plug. You remove it and check to see if it lights. It doesn’t.


Radio Control Flying: A Basic Manual:by Jerry Kelly: “We never seem to have the time to talk about how to fly before the moment arrives when the airplane is in the air. The more thought you give to flying before the first flight, the quicker you will learn. This point was driven home one day when I coached an eleven-year-old for his first flight. When he took the transmitter in his hands he gripped it like he had been holding it for many years. When I said “right” or “up”, there was no hesitation and as a result he made great progress during one flight. It was obvious to me that he had spent a lot of time with that transmitter in his hands, dreaming about flying. This is something not too many adults find time to do. Find time.”


RC Pilot’s Handbook by Jeff Junker: “The text is cleanly written, easily understood, and prolifically illustrated. It covers potential problems that might occur and offers down-to-earth solutions that should bring a troubled aircraft down-to-earth in the same number of pieces as when it left.”


Solutions to Landing Gear Problems by Jerry Kelly:Almost all airplanes are designed so that the fuselage should be parallel to the ground. A nose-up condition is generally very easy to spot. The fix is simple! Shorten the nose gear or lengthen the main gear until the fuselage looks parallel to the ground or, if in doubt, a little nose down won’t hurt.”


Why Glow Plugs Fail by Clay Ramsill: “Why DO glow plugs fail? There are four likely probabilities, five if you count old age.”
