I'm new to the Forum and have spent the past couple days reading as many of the postings as I could. I am impressed with the vast array of knowledge and the willingness to share it. This will make my re-entry into the sport much easier. Thank you all!
Since I recently purchased a lightly used Como 40, I'm curious about their suitability for control line use. I understand that they are essentially a Super Tigre and seem to be reasonably available at a more modest price. What are their Pros & Cons?
Thanks....Thomas

Thomas: From what I've heard there more of a sport engine, can they be good for stunt ? I haven't heard of anybody saying so.

HI Thomas
I have not seen anyone use them much. and the later ones are prone to run away.
However if you have an older version with a baffle piston they work OK.
I ran a Como 51 in a SIG Magnum and it worked very well, again this was teh older baffle piston version

I think Jack Sheeks used a COMO 40 in his black Spitfire or Hurricane in the 1970's. Didn't see it mentioned in the inevitable construction article that appeared sometime thereafter.
I had one, and never did try to dial it in for stunt. Today with the approach of flatter pitch props to let engines wind to nearer their power peak, while increasing fuel draw at the same time, in a low-2 mode, might suit the COMO. As I recall, it had a dished form to the head fins that resembled the early X-series STs, and may have been a clone.
Not particularly light, good starting, apparently a bunch of power... Only concern might be parts replacement, unless there's a source of interchangeable ST parts...
