Hi,
Can anyone provide some guidance on where to start with prop selection for my recently converted ST 60. I had Byron Barker rework the engine for Stunt but am wondering what prop to start with. I was thinking somewhere in the 12-5 range. Any suggestions.

I would start with a 14 x 5 at least

Thanks Randy,
I have been an RC guy for the last 30 years who just found control line again over the last year. I am having a great time competing, was booted out of beginner at this years brodak contest and just won my first intermediate contest in philly.
I will be flying this on a plane designed around your SV11 wing. A 14 -5 sounds huge from an RC prospective but I will give it a try. Would that translate to a 13 - 5 three blade?? Ground clearance may be an issue.
Thanks for the advice.

Hi Tim
Yes a 13 x 5 3 blade would be close to the same load

Is this "Blue Head" the one piece case, or the big and heavy "G" Series case? I don't recall a blue headed version of the traditional ST .60bb "v" case. Maybe I'm losin' it? :o Steve

Steve,
A 'G' motor and probably in my opinion the finest 60 that Super Tigre ever made. Ran in R/C with an 11/7 on pattern planes of the day and it was a dynamite performer. I would have never thought that this one could be made into a C/L motor simply because of the timing and yes it is heavy. Still have a NIB ABC version of this motor.

Hi All
The Super Tigre G series, of which they made differant Blue head versions was 2 piece case and heavy, however for its time it was a very powerful motor
, you saw many RC pattern flyers using this engine. I stll have one and many parts for that series here, it was a very common engine to see at contest and RC flying fields

Yes Guys,
The one I am referring to is the G series two piece case and most likely a little heavy, however, it is a great engine I have flown for many years in RC. I had Byron Barker convert it to CL for me and am looking to power my first 60 size stunter with it. I just moved up from beginner to fly intermediate so I figured the weight would not kill me in this class and it would allow me to get me feet wet with a larger airplane. Who knows I may not even like the feel.
Thanks for veryones comments.

Ah...so, I didn't lose my mind...yet...thanks for that! y1 I used a G.65rv in (then) C speed back in the middle '60's. First, with their 2 piece iron/aluminum piston/lapped steel sleeve. That was a terrible idea! The following setup was cast iron piston in steel sleeve, just like a .29...also not great, just ok, and delicate. I did try the ringed piston/cylinder setup a bit, and was not pleased. I needed about 15mph more to be competetive, locally. I never could get one of the ABC setups for the engine, so after 2 years on backorder, gave it up as a POS. I think World Engines was ST's biggest handicap, tho they seemed to do ok for OS. D>K Steve

I flew an ST Bluehead in a Dirty Birdy for about 15 years in pattern. It was the ringed version, and ran great. I finally sold the plane and engine and it was still running strong.
