The XR-74 is an experimental craft, small, slow, lightweight, and operates gaslessly.
Using the New Patent pending "KerGO! drive".

Take off from Land, Air or Sea.

Throttle up to 100% to Activate the "KerGO! drive".
Brake sets the "KerGO! drive" to reverse.
Set trim slider down to pitch up slightly.

Steer with Yaw, Pitch and Roll, GENTLY!

AG1 activates AND deactivates the boosters jets. (Use them sparingly as there is very little fuel.)
Use the boosters to gain elevation.
AG2 will jettison the booster jets once empty.

AG7 opens the canopy.
AG8 controls the Gyro. (only turn off if you have sufficient speed.)

Now you are basically a glider except you have the safety and security of the new "KerGO! drive".
Have fun!
