Hi Charles, as a rule of thumb, two of the same motors does not equate to twice the power but to 2.25 the power due to better prop effeciency.
Thanks for the reply! That's good news, and I thank you for it.
I like to fly airplanes from 72in wing span to 85 inches. I can put them into my VW Vanagon Westfalia in one piece and not have to take them apart all the time, which sometimes leads to errors. I also fly a 1/4 scale Cub and that one I have to take the wings off. My 85" PT-19 and smaller models fit just fine, up to three at a time. assembled.
My interest is models of that size also, except for my 90" 1/3 scale Gee Bee Z. Are these models you mentioned electrics?
I use only A123 Li Ion cells which I convert from DeWalt power tools and for my transmitter and receivers I use converted Black and Decker 1100 Li Ion (A-123) This way I can charge up in an hour all the batteries that need it rather than planning a whole night ahead.
Is this "top secret" information or do many others know this? I'm actually surprised this is going on? Very cleaver. Can we talk more about this, destroying Black and Decker and Dewalt power tools, for the benefit of modeling?
I have written many articles about the T-50 but never had the pleasure of flying one.
I'm sure your referring to the actual aircraft.
Thanks for the kind words, I am still writing about 1/2 time now for various publications including Plane and Pilot and PlaneFax an Internet Aviation Newletter.
No thank you necessary. It's not hard to believe I was reading you 20 years ago. Are you still "Stormin?" We are older but still young enough to be controversial? Or is it actually "ahead" of your time?
It comes to mind the Article you wrote on the Jenny. That article had an actual affect on me, as many others had, and now I have the opportunity to actually thank you for it, and all those other great "inspirational" articles.
I have extreme interest in knowing what you've written on the T-50? I've had interest in General Aviation my whole life, having taken my first flying lesson in 1965. I hold a few ratings, including Commercial Seaplane, and my last airplane, and I mean just that, my last, was a Lake LA4-200T. I actually built that model from some one's kit?
Anyway, because of you, good, bad or indifferent, I will build an electric model of the Cessna. You do have me on the hook, now make me a believer in electric's. It won't be difficult because you're actually "doing" electric. Besides, I know I can count on you for help in an area I know nothing about. Please, keep this in mind, I have absolutely no knowledge or experience with electrics. Never read a word about it.
Interesting math. At 84" in span, the scale prop size is 15.5". At 72" it's 13.5". I'll round it off. Now I'm considering the 1/6 scale at 84".
This would allow for the next size in engine choice. Possibly the AXI 4130?
Thanks again Norm,
