I have an old ST 60 RC that I would like to convert over to control line. What Venturi and needle valve assembly are best? Who does rework to these engines?

The two best known reworkers of ST 60s right now, IMHO, are this section's Moderator, Randy Smith (Aero Products) and Tom Lay (T&L).  Either can hook you up with the proper Venturi and NVA.

I have to agree with Bill on this one. Randy Smith sells the BEST NVA's for ST60 and most any other engine out there. He can also privide you with a venturi.

Hi Steven,

Randy's Aero Products NVAs are the best on the planet by a long shot, bar none.
