i would like to add the .46 la engine to the list of "piece of crap engines"
When i first bought it, (my first engine ever, first time flying) it never ran right from the start. it sounded horrible and sickly, it vibrated a lot, (so much that it caused my isolated tank to foam) and it never had any power. it also deadsticked quite often, maybe about 1 out of every two flights, and it would not matter where it was in the throttle range, it would simply die. i was getting really fed up with this engine, and nobody at our field could figure it out. (i never landed this plane and we never had a prop strike) eventually, it managed to vibrate it's own propeller loose, it over revved and died. i am not kidding, it vibrated it loose and it spun free on the shaft. at the time i was into the habbit of checking my prop nut after every flight, so it was not loose and there was no warning. from then on i loathed this engine and vowed never to buy one again. i then sent it back to os who said it was our fault but they would repair it because they were so nice, and sold it on ebay for $20 more than i bought it for in the 1st place. i then turned around and bought a .46 fx and i never looked back. the la engines are much to expensive for what you get out of the deal, and i will never buy another one and i would also strongly urge others to stay away from them as well.
