Electric is totally the opposite of what you said.....
Turn the switch on....it runs....every time.
Turn it off....stack it in the corner...come back 2 years later and it just runs....no rusty bearings or corroded parts.
Chargers and batteries....I have been using the same chargers for the past 5 years for thousands of charges.....I just don't get what you are saying.
I know for sure I have over 1300 flights on just one F3A airplane....and I have 3 of them.
I also have one more with the 170 CDI that I gave up on. I might have flown it 50 flights because of that engine.
However.....I still have 55 gallons of CP Heli 30% fuel....I really would like to fly the YS engines but I am reluctant to invest more money into any DZ engine.
I had great luck with the FS engines though....without that damn pump.
