33. ALWAYS provide for some form of emergency engine/ignition cutoff. At a minimum, install an external switch that cuts off power to the ignition. Better yet, add to that an internal ignition cutoff, that is connected to a spare channel on your radio. Optical remote cutoff modules from SmartFly or other providers, work really well. Make sure the assigned switch is out of the way, so you do not hit that switch accidently while flying.

34. Tygon tubing, of the type mostly used for gas engine in model airplanes, degrades over time. Check the tubing on any airplane you have acquired, especially at the ends. The piece of tubing inside the tank that is attached to the clunk and dipped in fuel, will likely get hard in a year, loose its flexibility and could be the source of fuel draw issues if not checked.
