I will just save the money for the engine going on the pulse 40 which I think will be a OS 46ax rather than the OS 55ax ABL because I read there is not that big of a difference but I may just spend the extra 25$ or so and get the 55 because if I go larger I wont have any regrets if the 46 wont cut it.
If I were buying a "40 size" two stroke engine (for the Pulse or other sport plane) it would be one of the bigger ones.
The cost is so close to a 46, and as long as you use the throttle as more than an on/off switch, I think having extra power available is a good thing and worth a few extra dollars.
