He may not look too special, but with the power of FunkyTrees I added quite a few automated features.

Controls: when on ground; throttle to walk, roll to turn, brake to brake, and use the weapon labeled "jump" to jump airborne and automatically enter flight mode; you can also jump off a ledge to enter flight mode.
When airborne, use normal plane controls (the Trim works but there's auto-trim anyway), the weapon labeled "Plasma" to shoot a plasma blast (ignore the "no ammo" error), and VTOL down to slow down.

Automated features: Auto-Trim, Wings fold at high speeds, wings flap when in use, Toothless blinks and changes facial Expressions slightly when you identify an enemy, the legs run/walk somewhat realistically, Toothless flaps his wings at low speeds meaning he has a 0 stall speed and can still reach mach-1 in a dive, and Toothless can fly backwards (although he's not very good at it).
To land, simply slow down to roughly 50 MPH, and fly low to the ground and toothless will stabilize himself, then drop to the ground when you drop a little farther.
