Sometimes super light is not necessarily a good thing. It depends on the plane.
I have a QQ 85" Yak with a DA-50. If the BME 55 is lighter, the plane would practically never balance without adding lead.
For a GP 27% Cap with only around 1100 square inches and designed around an OS 160, any 50cc engine, save the elusive BME 55, is super heavy, IMO, especially at higher elevations. P2W is one thing, but wingloading is equally important!!! But it seems that no one gets it or cares...I see too many planes like this with 31+ oz/sq.ft. wingloadings - my 102" 32% Yak has a lower wingloading!
