Read the whole description before downloading/making assumptions. This is probably as close as one can get in this game to producing a legitimate 4 cylinder engine model. It does not use the piston gizmo or any mods, and actually goes through a stroke-like cycle. This method in a way exploits the auto-pilot function and uses it to cycle the engine. If you will note the cockpit and small wings towards the rear, that is essentially the camshaft, valves, and ecu of the engine. Like a real engine it still needs to be cranked up, which is why two moment producing jet engines are included, they do not need to be used once the engine is started (see instructions). It includes 4 vtol engines and 16 nozzles cycled with rotators controlled by the auto-pilot, along with what was supposed to be a blower. I tested the blower with a dyno I had built and it didn't provide a noticeable power increase so I tried to remove it but apparently the engine won't work without it so it stays. This is a real piece of work. It took hundreds of tries and several hours to make. Also, please PLEASE try to improve it. I am still not happy with its max rpm and it just blew up when I tried the spin mod. Hope you guys take this and run with it.

Instructions:
1. Activate group 7, hold down yaw right until after 7 is deactivated
2. Activate group 2, trim up
3. Activate auto-pilot (Enter on PC)
4. After the revs are high enough, activate group one and throttle all the way up
5. Trim down, deactivate group 2

Unfortunately, because this engine uses the autopilot function, vtol, pitch, roll, and yaw become unavailable. The controls that you have to work with are Trim, FireWeapon, and LandingGear and AG groups 3,4,5,6 and 8. Regardless, it is still possible to build a controllable car using these controls and Activation Groups.
