Description: Stunt Pilot, Midway #548, 3/71, electronic sound (plane and siren noise). There is a Bi-Plane that is not visible until the game coins up and the black light turns on. The plane flies in a circle. In order to score points the plane must go over the mountain, under the bridge, under the arch and through the hanger. If it crashes, an ambulance comes out of another building, and runs around with the siren on. Player has up and down and speed control. Most people who play it think the plane is a hologram. The Bi-Plane is behind a two way Mirror. It spins on a motor with A "wiper" on a board that represents the obstacles. There is another board that has a buzzing sound for the plane engine and for the Siren. Also see Midway's 1971 Sea Rescue, which is a similar game.

The motor speed control for the plane is a bit of a mystery for this game. The schematics do not match the actual motor speed board. And there's two different versions of the board. Both versions work equally fine so it appears. And if the board is completely missing, the game still plays, just the plane is at full speed... which makes the game harder, as it is difficult to get the bridge or hanger and then get high for the mountain, because the plane is running full speed and the climb rate can't get the plane high enough to get over the mountain, before crashing. Here's the parts listed in the schematics for the motor control board:

1. .01 uF 250 volt ceramic capacitor
2. bridge rectifier PD20 (2 amp, 200 volt)
3. 1N5239 zener diode (9.1v 1/2w) or 1N4739 (9.1v 1w). NOT USED but shown in schematic.
4. 1n5624 diode (5amp 200volt)
5. 470 Ohm resistor
6. GE C106 (sensitive gate SCR - xref to RCA C106, same as Bally -35 lamp driver board)
7. 2n4871 Unijunction Transistor (UJT) or NTE6410
8. .1 uF 250 volt ceramic capacitor
9. 47k ohm 1/4w trimpot
10. 18k ohm resistor (10k specified)
