RE: MVVS 1.6 Break-in
Oil:
Use the correct oil. Get an oil for AIR COOLED 2-stroke engines. DO NOT use outboard oil.
DO NOT use a synthetic oil for breakin. Use a real oil from melted and rotted dinosaurs.
Mix it according to the instructions on the OIL container. Something like 32:1 or 40:1 should work, but follow the instructions on the oil container to be safe.
Run a tank or two on the bench or on the firewall before you fly it.
Adjust the needles for good transition and set the high needle just about 1/8 turn rich.
Fly the plane for about 5 gallons and then switch to a synthetic oil if you want to.
