I missed some pictures, so here they are:

1. Tail wheel - the brace is Great Planes the rest is Powerline
2. Heavy duty switch and On-board battery checker. I set it for 7.2V (6 cells) - if voltage drops to yellow it means the battery voltage dropped below 6.8V 3.4V per cell). It is under load so the battery will have enough juice to finish the flight.
3. You can't see the battery checker, but when it's on it lights through the covering.
