Hello,
I have the plane and yes it it does look quite small for a 91 2 stroke, I think the O.S 91FX is a ment to be a real beast and I could use it but I will keep an eye out for a classic 2 stroke to go in it, I assume anything by O.S ,YS,Super Tiger or Webra will fit the bill. Was this the era of long stroke engines or were they of the sreaming variety?

The plane is so simple in its construction, you could make one from plans in no time.

Are there any specific retracts to go in it?

The canopy is badly cracked, does anyone know a source of a replacement one?
Regards,
Rodders
