Title: WTB ABC piston and cylinder set for OS SF .46 ?????????????????
Post by: frank mccune on September 27, 2018, 08:52:41 AM

         Hello all:

         I recently was informed that these sets are available.  Perhaps a figment of someone's imagination.  Perhaps a Brian Gardner set for another engine would be applicable. 

        Any suggestions re obtaining an ABC set for the OS SF .46?

                                                                                                                                                            Tia,

                                                                                                                                                             Frank McCune

This is from a thread on RC Groups:   If the liner dies, an ASP 46 (true ABC) piston and liner set will drop right in if you notch the flange at the appropriate spot to take the locating pin.

I have never tried this myself so I can't say for sure, bet Randy knows.  George

These swine are I think ' the Clone ' .

If I remember right , the timings 140 / 110 . Assume all the ' sticker I.D. ' on the bypass are the same , perhaps .

The ASP is said in there ads , to be Acceration Speed & Power  . A.S.P. , not a Viper ! .
Their FSR 40 has 160 Ex Timing , way high for stunt & the higest of the FSR clones .

Dunno if the FS clone is the same trip , but would expect so . Incidently the ' Royal 46 ( or is it 45 )
Crank'd go in the FSRs & T.T. 46s , to stroke them . IF you ground down the O D of the crank web .

Plus other drivle there indicates bore & stroke DO NOT MATCH .
