Full throttle and unattended . Burning down the house. You start your engine, peak it up and head for the flight line carrying your plane and transmitter. When you reach the flight line, you place the plane on the ground. Its nice slow idle gives it no tendency to roll, and because it is a little nippy, you decide to put on your flying gloves.
Nothing can go wrong.
Lay your transmitter down when unattended. After charging the 12v starter battery overnight, I pulled the alligator or in my case push clips out of the sockets in the power panel. About 10 minutes later I went back out into the garage and smelled something burning. Over on the work bench, the two exposed male ends of the charger were touching and were burning my wood workbench, next to some rags and who knows what else. Proverb, unplug power-cords and chargers from the wall when charging is complete to avoid burning your house down.
