Hi,
Are there any modifications required to install the OS 1.05 engine in a Freya EX2 SWM and a Freya OP SWM SSL-II as far as main gear ratios and the short shaft engine are concerned? Thanks

Are you saying you have the short shaft motor? If yes, then I believe you will need the fan hub from the V2 Turbulence.
Gear for 7.9 or 8.27 for Fai or 3D, respectively.

Short shaft

Hi Dr Ben,

Thanks for the reply. I don't have the motor yet. Just probing. I saw one at Super RC in Osaka, a shop I frequent and I'm thinking of buying it to try on my EX-II SWM SSZ-III with flybar. This heli currently has an OS 91 SZ and retains its setup from my last contest which was the 2007 FAI F3C Worlds in Poland. I also have a good offer from Hirobo for a Freya OP SWM SSL-II and thinking of getting it at a later date and eventually use the OS 1.05 on this Freya.

I gather from the other replies that the current edition of the OS 1.05 is with a standard shaft. How do I confirm which shaft a motor has when I purchase it? Does it bear a certain designation?. Apparently, for practical reasons, I should stick with the normal shaft to keep things simple. Then all I need to worry about is the gearing.

Thanks for the replies!
