• USER MANUAL *

AG1 - Reaction Control Nozels (RCNs) ON / OFF
AG2 + TRIM UP - High speed mode ON (About 200 Mph max speed)
AG3 - RCNs propulsive help ON / OFF (add about 10 Mph speed in low speed mode)
AG4/5/6 - Nothing
AG7 - Main engine gimbal ON / OFF (Required for almost all operations)
AG8 - Gyro OFF / ON (Required for almost all operations)
B - Wheel brakes and instantaneous main engine shutdown (Attention! The high speed mode engine is not affected, you must manually bring the TRIM to zero to shut off the thrust)

• SIMPLE FLIGHT *

1/2 OFF and 7/8 ON
87% engine, take off, PITCH DOWN to create forward thrust, PITCH UP to create push back (or slow down), ROLL for strafe (with a light YAW momentum) YAW to rotate in place
To land lower the THRUST slightly and as soon as the wheels touch the ground, BRAKE

• HIGH SPEED FLIGHT *

Procedure as for simple flight. Activate AG2 once in the air, and move up TRIM until you reach the desired speed.
This mode is not realistic. I inserted it only to facilitate the movement between the desired places, decreasing the tedious dead times.

• REALISTIC NASA PILOT EXPERIENCE *

1 ON
2 OFF
3 ON or OFF (you can chose as you feel more confortable)
7 ON or OFF (two different experiences, both realistic)
8 OFF
Increase the thrust of the main engine to take off, then use the controls to try to remain stable. WARNING! A considerable driving skill is required! (Like Apollo program astronauts!)

The Lunar Lander Research Vehicle (LLRV) was created to train pilots of Apollo missions for moon landings with the L.E.M.
I had initially thought about doing an exact replica, but it was impossible to find consistent information (each photo and each drawing in three views are different, sometimes marginally, sometimes in a very visible way, probably because the vehicle has been changed continuously, even during every single mission). Furthermore it is very difficult to understand the exact three-dimensional interweaving of the tubes of the frame from a two-dimensional picture. I therefore decided to make the project a partial replica, partly simplified and partly modified for my personal taste. It was also impossible to replicate the exact operation of the gimbal (in fact the gimbal kept the main engine exactly vertical whatever the inclination of the vehicle, to simulate a gravity of 1/6) while the control was entrusted exclusively to RCNs. In SP replicating the gimbal was impossible, and I had already decided to reverse the operation, relying on the controls at the angle of the main engine. Other minor changes are due to the need to add two RCNs per side to control the ROLL, which were not present in the original version (obviously there are differences in the position of the center of gravity)
