Hello Js,

Js>>With mine I'll be able to see the trend in voltage - perhaps even chart it using a bar graph on the LCD along with an estimation of time left before 3v. I might even add some beeps to make it really fancy <<

Hey Js...I flew RC's for many many years... Was on a show team in real airplanes and well as RC planes. My favorite preformance was landing a airplane upside down and taking off upside down (this was a RC bird). It was a Stuntmaster with a Rosse 45 on it. 2HP enigine. My realtime favorite was a 200+HP Pitt special... It was smaller than a cessna 150, but had more power by far. It was a two seater...suicide stick kind.

What you could do, is run when the voltage goes below 5 volts, kill your engine survo. We used to run 4 1.4 volt to 1.5 volt Nicads for the receiver. That is equivalent to about 5.6 to 6 volts. Thus, if you can check your voltage, and kill your engine servo if it falls below a certain value.

What do they use nowadays for voltage in a airplane? 4 Nicads still? What frequency do they fly on?

I still have my Tube stepup...It was a R/C "pulsator" the rudder pulsated back and forth, and you push a button once to go right, Push it again to level off, push it again to go left. And if you didn't have enough turns in your rubber band to do enough turning, you were stuck in whatever you were last doing..<g> Then graduated to 27mhz... Then went to the Ham Bands. I only have a few 72 mhz radios. Then the went to 77 mhz? (or do I have them switched around). I do't know what they fly now. ON the public bands, I flew Green and white. 77.640? Its been to many years <g>
