I'd like to replace the OS 46 LA on my tower trainer 40 and would love to put a 4 stroke on it. I do have a brand new Saito FA-56 looking for a home. But I just cant see how I could mount the 56 without some serious modifications mostly because of the way the carb sticks out the back of the engine a good inch or more. Also the throttle lever is on the opposite side of the engine unless. I could easy enough re-route the throttle linkage to the other side but the carb sticking out the back seems to be a real show stopper. Are all small 4 strokes made this way? I really like Saito engines at the moment and I know the 56 would overpower the trainer but it would be nice to fly the trainer again with a little more power and a reliable engine. I know I could go with a 2 stoke like the OS 55 AX but from what I've read, they seem just as problematic (as the LA) so I'm not impressed with OS at the moment.

Looking for suggestions for a reliable replacement for the 46 LA.

TIA
