Flying the Minimum.

For the maiden flight you should choose a day with a little bit of wind, just enough to keep the rotor spinning when you've given it a flick. Check that yuur RC equipment is working correctly. Start up the rotor and do a fast walk into the wind with the gyro held at nearly 90°. At this point the speed of the rotor is not a function of your walking speed, but a funtion of time. Walk on till you hear this swishing sound of the blades. Turn on the motor and set it to half speed. Walk a bit faster and start turning the gyro nearly horizontal. Now you should feel the lift of the rotor. When everything seems alright, set the motor to full speed, do a few fast steps and gently shove the gyro horizontally into the wind. You're airborne - and I hope it stays that way. At full speed the gyro will now start to climb, be prepared to throttle back till it flies level.

There are some differences to flying a plane, that you have to watch out for. When you want to climb or descend, you use the throttle do to this, not the elevator. As the gyro is not inherently stable, you have to end all manoeuvres you're doing by actively putting the gyro upright again. In turns the Minimum behaves like a plane with ailerons and elevator. When you want to turn, bank the gyro and then pull a bit of elevator to get it round the turn. The main difference to a plane is, that you have to apply far more power in turns to keep the flight path level, otherwise the gyro will rapidly loose height. And the response of the gyro is far more sluggish than that of a plane. When you're cruising along and the gyro starts going somewhere you dön't want to go, use short, relatively hard corrections instead of small, long ones.

It's important to land the gyro straight into the wind, otherwise it is likely to turn over and you'll have to replace one or two of the Nylon screws holding the blades. When you want to do a dead-stick landing, simply turn the Minimum into the wind and turn the motor off. The gyro will come in at an angle of about 60° and you just have to use elevator to pull it out of this dive at the right moment.

Sooner or later you're going to crash the Minimum. Most of the time nothing much happens - I'm still on my first set of blades, by the way. Things that come in handy in such a case are some Nylon screws for the bades, some styro ca for the tail unit and a 3 mm cf rod to replace a broken landing gear.

Have fun!
