I've a Honker in my hanger powered by an Enya .19 and it flies well with the exception that with no headwind it is a little hard to get up to speed for takeoffs. It is actually a good windy day flier and is of course no problem to get airborne with wind. Once in the air, it flies well. I'd not go under a .19 and would think a .25 would be the better choice.

I consider the Honker a proto park flier as it can be flown in a fairly small box.

Good advice from those suggesting light servos, as the Honker is best when kept light. Don't hesitate to use a hole saw on the wings and some opaque light covering and a small battery pack and foam wheels.
