ARFs and WEIGHTS
Two examples - hanger 9 sport cap, with saito 91 - came out LIGHTER than what the box stated...I was exstatic!
Sig extra 300xs - box states 12- 13 lbs. I put in a saito 180, which is extremely light compared to say, a moki . Even left the wheel pants off (5 oz). Plane is 14 lbs 3 oz!!! Now add 24 oz of fuel...
