I flew with my LA40 for 4 yrs. in a salty dry lake in south baja, now a days it is at the end of my fishing line!! it was an excellent engine and out last 2 FX46. it always used a 10x6, for a while, when the first FX46 passed away, it was at the nose of a dazzler, then in it`s elder times flew a Buzzart Bomb Shell 3 channels, then it went back to the dazzler nose and died.

Romantic but not good for your ultimate.
