Default RE: Engine for Sterling Ringmaster Jr. ??

Kdheath,...

Thank you very much for the help and advice. Yes,... I checked out Tower's web site and noticed the Venturi and Neddle Assembly for the .10 STD engine. It came out to less than $20 (including the shipping) so I ordered those items. I figured I'd try the venturi and needle assembly to see if it works. If not I'll take your suggestion and just wire the carb. open.

Just wondering,... are C/L engines setup with different timing?? If so,... would ordering the piston and sleave for the .10 STD help to truly convert this R/C .10 into a Stunt .10??

Thanks a million for all the help and contact info.

Sincerely,

You're very welcome. I expect that the motor you have was only made in one version, with the choice of carb or venturi. This is true of the OS 35S, for instance, that was made about the same time. I hope the venturi and NVA fit. That would be very convenient. The FP sleeve and piston are Schneurle ported and ABN materials, so they won't work in your older cross flow crankcase.

My son bashed his SIG Skyray last week and was reduced yesterday to flying his Challenger with an OS LA 15. What a sweet little motor! Stock muffler and venturi and runs smoothly and very quietly. Couple of flips to start. I think I gave $25 for it used and is worth twice that. I would put that in the Jr Ringmaster if I had it to do over again.

It was a gorgeous day in the Twin Cities yesterday, with 78 degrees and light and variable winds. At least twelve people flew at our field!
