VIPER 0 Posted October 22, 2009 Share Posted October 22, 2009 Or perhaps a camshaft? or a link where we can find one? Link to post Share on other sites
VIPER 0 Posted October 22, 2009 Author Share Posted October 22, 2009 Dad the OS 91 doesn't have a camshaft? Do you mean crankshaft? Or did you mean con rod? Because didn't we think it was the connecting rod that was the issue? Link to post Share on other sites
Peter 0 Posted October 22, 2009 Share Posted October 22, 2009 Have you tried just engines for the spares,if they haven't got one then you could try John D Haytree who advertises in most of the model mags. Pete Link to post Share on other sites

Nutz 0 Posted October 22, 2009 Share Posted October 22, 2009 As per parts listings for the OS 91 FX http://www.gpdealera.com/cgi-bin/wgaprt ... I=OSMG0591 The part details are OSMG3972 29505000 O.S. Connecting Rod 91SX-H And after a google you get http://www.modelhelicopters.co.uk/acata ... 1SX_H.html I think you will find a lot of the OS 91 SX parts are the same So £15.99 for the con rod from Midlands heli.
