Post by: frank mccune on June 06, 2018, 01:01:48 PM

     Hi All:

      What type and what percentage of oil would be a good mix for the above engine.  The engine will be used for stunt and sport flying exclusively.

      Suggestion and/or comments?

                                                                                                                                                 Be well,

                                                                                                                                                 Frank McCune

OS 35 stunt  as in  OS 35S  or  in  OS 35 FP stunt?

If OS 35S you should run 28% oil half castor, be  VERY careful you can tear out the  TINY wrist pin boss easy if it is fitted  too tight
