Tweaked a few things to closer resemble the real thing and added some smoke on the skids and tail for fun.

-Blade pitch increased to -/+ 14.5 (from -/+ 12.0)
-Fuel tank capacity reduced to 14.5oz
-Fuel consumption adjusted to closer resemble actual fuel burn rates for the O.S. 55HZ-R (approximately 1.3oz/min at full throttle).

-Channel 5 switch: Skid smoke on/off.
-Channel 6 knob: Tail smoke on/off/adjust.
-Smoke is colored to resemble position lights on actual aircraft (red left, green right, white tail).
