The professional timingbelt gear for engine input-power up to 8 (9)Kw (with Power Expander).
Double ball bearing for high radial and axial loads (3D-aerobatics and towingplanes).
Resists a permanent load of 305N (31Kg) axial, up to 600N (61Kg) axial-peak.
Adjustable over a wide range of engine input-rpm to receive the optimum efficency of your airscrew.
High performance aiscrew mounting for save operating.
Engine mount with 2 x M4-screws on 30mm bolt-circle.
You have to choose between two general types:
- for engines with low rpm/V (gear-ratio 1.5 to 2.4)
- for engines with high rpm/V (gear-ratio 2.57 to 4.0)
Please be aware:
If you choose driver-/ engine pulleys with clamping cone it could be possible that you have to shorten the engine shaft on 6mm and 10mm shaft-diameter.
On engines with 4, 5 and 8mm shaft, the clamping cone is hollow so that there is no need for shortening.
Screw fitting pulleys need a flat area on the shaft.
For using Single-Gear you are although able to take direct-drive engines with higher number of cells but although take helicopter-engines (SCORPION, KONTRONIK, HACKER etc.) which are predestinated.
With the PC-Tool Drive Calculator (www.drivecalc.de) you are able to get a pre-orientation what a engine-gear combination of your mind is possible to achieve.
But obviously we will give you advisory support if you wish. Please get in contact with us.
On the page Measurements of engine-/ gear combinations you will although find further informations
