I have flown glow and petrol powered planes for 15 years, but never anything electric. I have finally decided to convert my Blue Phoenix to electric, and a bit of advice would be welcome.
The Blue Phoenix is a two meter polyhedral balsa glider, very similar to the Gentle Lady. I want to add a motor system to get it up to thermal altitude. Nothing fancy, just enough to make it climb gently.
How do people manage battery capacity during thermal flights? Should I use a separate receiver battery and use the main battery just for the motor? The worst case scenario is that the battery is nearly empty after a climb, and there won't be enough capacity left for the rest of the flight. In good conditions, this plane can easily stay aloft for half an hour, and I don't want the receiver to shut down in the air.
As you probably know by now, I am a beginner when it comes to electrics, so any tips and advice are welcome.
