Copy of Mosquito helicopter from Greece

Since there was no Cash to buy a kit, i used a mini lathe and also a milling machine to built most of the parts.
Of course i had to make some changes of the original design due to the limitation of my equipment.
The motor is a Rotax 503 and a custom built primary reduction drive 1/2 with certifugal clutch similar to the Mosquito.

In conclusion...there's is a lot of job to be done but it's a soooo unique and interesting project.


Making the main rotor blade with aluminum 7075 


about 4000$-6000$ with used blades and used motor.

Rotor Head

it's not actually a mini lathe but compare to other industrial lathes, it is small chinese lathe with a distance between the chuck and the live center 20" and a chuck diam approx 6". With this lathe I did most of the parts, but to be honest you need a more stable heavy lathe with at least 40" travel so you can actually make anything. Aso the "center mast" of the mosquito is 4130 steel tube, it is a very difficult and hard material for these lathes, so some parts mast be done somewhere else. 

main rotor bearing are you using are from car-track wheels and they are sold as pairs. Each one are 3 separate pieces with inner-outer sleeves so you can adjust it when the main gear is in place.

Grades of aluminum and steel used: aluminum 6082 T6,7075 T6, steel 4130.

I use sealed bearings with permanent Grease but this is temporary. Later I will modify the blades grip with one piece aluminum and different type bearings similar to R22.
