As I became a helicopter addict I had to build a collective. This is the material I used:
- a bike seat post (5$)
- a bike grip (3$)
- Logitech Throttle Quadrant (new about 60$)
- incidentals (buckles, one buckle with a M8 screw thread, screws, total 5$)
Total: about 73$
The construction is very simple but effective. I could attach the collective to my seat (old Fiat Chroma leather seat) where the fastener of the seat belt was attached. The remaining levers from the throttle quadranrt can be used for additional functions in the R22. There are also 6 buttons. For the cyclic I use a Logitech Extreme 3D. I also have a CH Yoke and one additional throttle quadrant on the other side of the seat for all the other aircrafts.
