30% ARF's
I have an AW 300 Profile arf with a RCS 180. Really good combination and quality from both.
Comparing the spec from each manufacturer AW advertises an AUW of 16-18lbs. with 1380sqin wing area and Lanier advertises 17-20lbs. with 1473sqin of wing area. I don't know in reality if the difference makes a hill of beans. I guess as long as I can stay under 20lbs I'll be alright.
