I have recently started to fly electric, I still have my YS160, which is already starting to be "dated", but is still an amazing motor.
But electrics ARE already starting to over take glow in F3A. I just liked the idear of being able to fly at my field in summer EARLY, but here was the catch, there is a curfew until 0900, and 1000 on Sunday's! Electric is allowed to fly before the curfew, so I now have an Angle 50 for practice, and LOVE how easy it is to duck out to grab a few "quick" flights inbetween doing other stuff at home, it really is quicker the set-up, fly, then pack up again.
The other advantage I think electric has over glow, if my YS goes "off song", it is a real effort to pull it appart, and get it back together, electric is more what I would say, "plug & play", like another post said, if it is not working, it needs to be swapped, yes you can pull appart the motors, but it is rare. Just my two cents worth. Matt
