does anyone know if i can just buy the crankcase for clockwise rot and swap with my ccw rot webra 91 to reverse dir. or can i just reverse the cylinder and head, just curious, instead if buying new motor, or can i get a cw rotation c-spec with heim crank.

You can ask Cyber heli for the CW Webra crankshaft. As far as I know CW OS91 C spec doesn't exist. You can also buy a OS91 SXH and change the crankshaft to the CW one. Revolution has them.

If you really want a Webra, why not just buy mine ?
You can see it up for sale at SkyLine Models if you go down the '4 Sale' link. It's up for £140 (approx $200), and comes with a 3DNT fan already modified to fit the Webra, and already fitted with GV-1 magnets

i would prefer to use an os but since a heim crank cw c-spec does not exist, i have to use a webra os shgl, the heli im buying comes with a webra ccw rot, which rotation is yours carps, or can you tell me where to order a crank, at this point i think ordering a crank is the cheapeast thing to do, is it just an 8 mm heim crank, or is it more specific than that for the 3dnt.

Mine is a clockwise running engine.
You are probably right regarding it being cheaper to buy a crank, but then you could sell your Webra complete and with the proceeds buy mine and still have change !

To buy the crank on it's own you will probably have to approach CyberHeli or Webra direct.

Rick,

Do not forget that you will need to :

- reverse the one-way bearing of the main rotor.
- relace the L shape piece that drive the tail rotor.
- replace the fan

and of course change the carnkshaft or the engine for a cw one.
