Dear Fellows,

Thank you very much for the advices !!!
It seems the "way to Webra" is very attractive and will consider to sale
at good price some of the best OS.91 I have in order to move to the
Webra-world as soon as possible. eBay is working just for this
and fine for me, at least so far.

As for the castor oil I support Jan's statement only within the limits of
Scandinavia where in most of the time the weather is too cool for
the castor. Still the best results on OS.91 I have got with with 12%
nitro, 6% Castor and 14% Aerosave(Graupner synth.) oil. After
4-5 gallons of fuel like that the rpms are almost the same as for
new engine.

Regards,
Nikolay
