Leave it to Peter to pick up one of the wierdest RC models we've seen to date. This is the by Unique. Unique is the best word to describe this thing too. The 1320mm rotors have no motor basically making this a flying windmill. Some autogyros have a pre-rotator motor to give the blades a kickstart, but this relies on wind. The guts feature a 4250 outrunner motor with a 60 amp ESC ( 4S 14.8V 3000-3300mAh Lipo battery recommended) Peter being the only one who's actually flown one of this crazy machines, was a little more excited than the rest of us. Flying autogyros takes a lot more attention to the craft and the surroundings (a.k.a.
Situational awareness) than normal fixed wing flying. Also, more attention to which direction is down wind. When flying downwind the thing has a mind of it's own! The biggest challenge is keeping the blades moving at all times during flight. Maintaining proper head speed is done through throttle and pitch management. Too slow of a head speed will cause the gyrocopter to roll violently to the left. The inertia of the blades will carry the entire gyrocopter over and crash.
Plans Built Gyroplanes. In your search for a gyroplane that suits your style and mission you may have found a great little ship that is only available by building. Article source: Popular Mechanics. Gyroplanes fire our imagination like no other aircraft. Before there were helicopters, newsreels featuring the.
At the end of the day, there is nothing quite like the 'thwop' of the gyros blades. This is a blast to fly, but definately not for first time flyers.
If you are looking to challenge yourself as a pilot and step out of your comfort zone, this might be just what you're looking for. If you are interested in gyrocopters but a little intimidated by the price, you might want to start with the simpler.

In either case these are something out of the ordinary. If you are looking to shake it up at your flying field, gyrocopters are the perfect way to do so. Juan de la Cierva, the father of the autogyro, discovered very early on the issues you had with the model. To solve this he arranged for the blades to be able to flap up and down independently in a hinge.

This allowed for the leading lagging blade problem by letting the leading blade fly higher then the lagging blade. Your model does not appear to do this. Worth the modification.
ref: Nice Model have fun. As a passing point a full sized autogyro can and does land vertically and in a relatively low wind can hover much like a helicopter.
They are however a fair bit slower than a helicopter with the advantage of much better fuel economy. I don't know about this model (yet, I've ordered it), but the auto-g(2) definitely allows for flapping. Problem is, at low headspeed the blades don't flap, because there isn't enough force on the blades by the air, due to the low headspeed. So they don't flap quite yet, and that's why the model wants to roll left.
Actually, it would be better to outfit a model like this with a clockwise prop, so the motor torque counters the tendency to roll left at low headspeed. I tried it in my early gyro-times, but it's better to just get the head up to speed:) to reply. Hmm, interesting point.
I checked out the pictures in this thread and on hobbyking, and indeed there doesn't seem to be any mechanism for that (unless they are hiding a feathering shaft&dampeners). Bear in mind though, that this size is close to a 700 size helicopter. I have one of those. The forces on the blades are LARGE, and even the most rigid rotors have to give a little. And even if they wouldn't, I'm sure the blades themselves would bend a little at the bolt. Actually, isn't the sound the blades make a demonstration that the blades do flap?
I thought flapping is the origin of that sound. My Grandfather is 78 and has been flying and building full scale light sport and ultralight aircraft both privately and commercially his entire life.
He has told me over and over that due to the autorotating head, once one is comfortable with an autogyro, it is the safest aircraft to fly because, the motor can shut off and the craft can be auto rotationed in softly! Peter, As you were stating before, pushing forward stalls the blades by not allowing any degree of blade angle to be effficient and actually tries to reverse spin the head.No front flips!
