For installation in the model a 450-550cc tank is Suggested.
These will allow 10-12 minute flights.
Locate the fuel tank so that the top of the tank is 5-10mm
(1/4-3/8") above the level of the needle-valve.
Be sure to use a pressurized fuel system by connecting the
muffler pressure nipple to the vent-pipe of the fuel tank.

GLOWPLUGS
Since the compatibility of glowplug and fuel may have a
marked effect on performance and reliability, it would be
worthwhile to try different heat range glowplugs.
Recommended O.S. plugs are Nos. 8, A5 and A3.
Carefully install the plug finger-tight, before final tightening
with the correct size plug wrench.
