I attended the Keystone Clippers R/C Swap Meet today in North Huntington, PA. I was fortunate to win the door prize, a Parkzone Sport Cub and a Spektrum DXe transmitter!

Thank you to the Keystone Clippers R/C Model Airplane Club for a fine event. Looking forward to next year!

My largest ESC is a 45A Turnigy Trust that I use in my Funcub. Most electronic speed controllers that I have used are enclosed in heat shrink tubing. The tubing protects the printed circuit board from conductive elements but it also prevents heat from escaping the circuit during operation.

The typical ESC is comprised of a small printed circuit board that is mounted on an aluminum heat sink. There's a lot of heat generated when the controller components are doing their thing, providing variable power to the brushless motor and the job of the heat sink is to dissipate that heat. Normally, a properly applied heat sink is exposed and residing in a stream of forced airflow so as to shed heat generated by the components mounted to the sink. I've always thought it counterproductive when I see shrink tubing tight around the heat sink on an ESC.

As a project, I'm moving my Funcub ESC to the tunnel under the battery holder to reduce clutter under the canopy and in the process, I have removed the tubing and taken steps to ensure the circuit board does not experience a short circuit as a result. I coated the board with an electrical insulating spray product. For further protection, I lightly glued a thin piece of insulating material to the PCB side of the ESC.

The modified ESC might have slightly decreased in height since the removal of the shrink tubing. It fits with no problem in the tunnel and should be cooled quite well from prop wash since the tunnel is open at the front and below the wing. I don't land on water and do not anticipate flying in the rain. Besides, I feel the circuit board is adequately insulated from any moisture that might enter the tunnel.
Stay tuned!

I've noticed this book previously mentioned on RC Groups and figured that I should read it and hopefully expand my knowledge of flight. I have no experience with full scale aircraft and limited experience with r/c aircraft, so, there's room for improvement.

Speaking for myself, whenever I've crashed my planes, I immediately wished to be able to replay in my mind the moments leading up to the crash because I did not know or understand what happened and couldn't visualize it for the most part. Usually, the part I remember is the plane heading straight for the ground while my right thumb is frantically pulling back on the elevator control. Too low and too late.

I wish that I would have read "Stick and Rudder" by Wolfgang Langewiesche sooner. I have not yet finished it but I feel that I already understand so much more about how and why planes fly. Part One explains how a wing is flown and explains lift and buoyancy. Those are stall reducing lessons and would have helped me immensely.

I bought the book used online and it is in like-new condition. The copyright date is 1944. I'm surprised because the book is easy to read and the language does not seem at all dated. The tone is conversational and the explanations are easy to process.

I'm looking forward to a time when I no longer think about crashes but instead enjoy pushing my r/c flying skills further along.

Has anyone else read Stick and Rudder? What is your opinion?

I'm really happy to have the Multiplex FunCub thread as a resource for information and entertainment. I've been staying current with the thread since joining in November and I'm also reading the thread from the beginning as time allows. Lots of talk regarding motor selection, vibration and broken shafts in the early days. Luckily, for me, FunCubParts.com greatly simplified power selection. Mine is the standard set.

I received a FunCub kit as a Christmas gift along with a DX6i. My son Andy and I completed most of the build while he was home over the holidays. I've since been working out servo travels and xmitter programming. Also want to stiffen the landing gear.

The frigid weather here in Western Pennsylvania is providing me time to think through the process and hopefully, work out bugs without feeling compelled to rush out and fly. I admit to putting the cart before the horse and lacking foresight many times during this build but time and experience will help going forward.

I've flown a Hobby Zone Champ and Blade MSR x heli. That's the extent of it.
I am flying the Real Flight sim and of course reading as much as I can concerning the fundamentals of r/c flight.

I've joined the AMA (no number yet) and hope to have a trainer with me on my first FunCub flight.

Thanks for reading this
