I have a supply of engines specially setup for F1J including flood off fitting.
For those wanting the very best, the Cyclon 1cc engine with flood off fitting and glowplug.
For those wanting the next best at a much better price the GRS with flood off fitting and glowplug.
Also have folding props and flood off actuators.
The Cyclon and GRS are identical in every way with the Cyclon having about a 1000 rpm edge on the same prop. I plan to use the GRS on my F1Js in test flying and most competitions, and swap it out with the Cyclon for those special events.

Will have this on my website shortly.
