Overview

This is an attempt at using a single archive to distribute all the files needed to model an aircraft in FlightGear. This archive should be extracted into directory $FGROOT/Aircraft. Some files will then need to be moved to other directories. I've attempted to keep as many of the files in directory $FGROOT/Aircraft/OV10 as possible. Ideally I'd like to keep all the files in one directory, but currently FlightGear requires some of them to be placed elsewhere. The contents of the archive, and the directory in which each file or directory should reside, is listed below.

Contents

OV10-read-me.html	This Readme file	$FGROOT/Aircraft/OV10

Models	Contains the OV-10 3D model	$FGROOT/Aircraft/OV10

Bugs

I'm still fairly new to FlightGear, so some of these "bugs" may actually be features :)

bug	status
3D model has some bugs	The model is a from the Captain Slug OV-10A. The gear and control surfaces don't move.
It's still using the T-38 panel.	See the T-38 read-me.

Flying the OV-10

Takeoff, no flaps, apply full throttle. Sound doesn't change as engine is already at about 100%. Rotate at 100 knots and climb at 130 knots. To land fly downwind at 150 knots clean, on base slow to 120 knots, extending gear and half flaps passing through 130 knots. On final extend full flaps and slow to 75 knots (for STOL landing) or 100 knots (if you want a long life).

Let me know if you'd like more features, and if you have recent time in the OV-10 let me know if this model flies reasonably close to the real airplane.

Notes

The engine model uses the FGSimTurbine module of JSBSim. The thrust value in the engine configuration file is an estimated thrust for the engine/prop combination. Someday I'll add condition-lever inputs to the engine code.
