Hi Stuntguy
I would go a touch rich on take-off as the engine will unload once moving (pickup rev's) and this will prevent over heating.

Any two-stroke engine, whether gas/diesel/glow requires LESS fuel when under less of a load (unloading) than when under more of a load. We run them a bit rich at takeoff to compensate for the fuel tank draining during flight and providing less "pressure head" to the carburetor.
YS engines do not require this richening at the beginning of the flight because their pressure/regulation system compensates for the fuel burn-off during flight.
