RE: Plane/Engine combo...
Hi P.
My second plane after my trainer was a Bridi Killer Kaos with a Rossi 60...I was clearly way out of my league and opted for the WM T-34, strapped a 46fx on it, proped it down to get a little more out of it and SHE SCREAMS..... it's extremelly capable.....You won't be sorry with the 46... Yes, maybe a little more than the others but if the ax is anything close to the fx, reliable, powerful, easy to tune, and quick breakin.... you can't go wrong with this combo.... I think you will find it much more snappy than the LA.. I do understand wanting something different as well as bugdet concerns: Whatever you choose of the 3, weight will not be an issue: W/ Muffler: OS46ax-17.2 oz. vs ST G51= 18.4 oz., vs TT 46-17.1 oz.
I still use the T-34 w/ 46fx to warm up with...over 80 flights on it- this plane is also excellent to test and polish your skills in very windy conditions if desired. Good Luck!
