LA 40 has to be one of the great engines out there, mine is 5 years old and still runs good, for all of you that just left your trainer and went to the next level, save your LA 40 for a DAZZLER as your 3 or 4 plane by then you will know better how to get the best out of this great engine and ; if you switch to a 46FX 12.5 X3.75 or 12X4 or 11x6 just like I did, your pocket will burned a little bit when you find out the small difference it actually makes and the money you spent.- Now a days my LA 40 is in an old timer!!

MDS is in my black list, I will not buy another one, bad carburator, do not last.
