Glow has already "seen it's days" and is "well past it's prime" . The Lipo was the very last nail in Glow's coffin as far as being the most employed power source in our hobby .

I liken it to Vacuum tubes , of which I am a Vacuum tube radio collector . There are literally thousands of Antique radio collectors who preserve Vacuum tube radios , even though the Vacuum tube past the torch onto the Transistor some 60 or so years ago .

Here's 4 of the real deal . Actual 1920s radios with Vacuum tubes , restored and playable . No "Thomas reproduction" junk here .....
