Hmmm.

FPE makes GREAT motors but they can be a bit heavy.

Thats a ruff size right there, because your going to wan't a 50cc size bird for the proper wingloading, but it will lack a little of the 50cc power.

Perhaps the new H9 80" cap would be a good choice. It has an 80" wing, but still around 1400sq inchs of wing. and people are getting them in at 14.5 lbs with a DA 50, so that would put you in at about 15lbs. that should be a good combo.

Also, the airwild extra 260 comes in nice and lite, so that motor could work there as well.
And it has an 85" wingspan with a little over 1400 sq inches.

Both are ARF's but I think would do your motor justice.
