Hi guys,
I was just wondering if anyone has had any luck using this engine? I've had one for years and have never used it. Had some of my engines out re-oiling them with mineral oil and ran across this old baby. I was looking for my ST G21/46, must be in a different batch of engines. I like flying the ST 46 engines, they cry a lot and are a lot of fun. I was beating up on my enya 60/ 7032 and decided to weigh the plane 77 ounces. I guess the enya doing what its suppose to, pulling the plane thru the complete pattern, just have to stay on top of her to be sure she doesn't run out of air speed. Would appreciate any input about the Bullring engine, Gary

Gary,
Although you will probably hear to the contrary, one of our local control liners (Chicago area) had really good luck with a Bullring 46. In fact, he was quite saddened when the years finally got the best of it and he put it into retirement. He was flying it in planes built for G21/46's and Enya .45's although I believe there might be a different footprint for the Bullring.
Let us know what kind of luck you have with it.
Best regards,
Richard Ferrell

I had one, and although (or because) someone had reworked it before I got it, I was never very happy with it. Mine ran smoothly enough and didn't run away, but it was pretty heavy for the power and I never found it to be too satisfactory. It was certainly no stronger than the average G21/46 and much weaker than a really good G21/46.
A stock engine would likely be a lot stronger but the run characteristics are unknown to me. There's a good reason people started running tuned pipes on those sorts of engines.

Hi guys,
Thanks for your input. I have the ST G21 46 sitting next to the ST Bullring 46. The Bullring weighs 1 1/2 ounces more than the G21, looks like a bigger engine but if its only a 46, I guess maybe power is in the same range? As I remember the bullring doesn't run like the G21, seems like its more like a wet two cycle rather than a four-two-four run. I believe the bullring has a lot of power, just harder to manage. I have one of those famous scores that I use for a engine test bed. When the weather clears up should give the old bullring a run. Have a great day and appreciate all input, Gary

Hmmm Bullring 46, weight of the ST 60 with the power of a good 40
I would stick with the St G-21 46
