Just finished up my Sig Akromaster. Finished this one with silk & Brodak dope. I built it with the extended wing. Power is OS .15LA with 2oz tank on muffler pressure. APC 8-4 prop all up weight as you see it is 19oz. Plans are to fly it on 52" lines. It needs a spinner & leadout eyelets that are in the mail or it would have a flight reprt allready!...Gene
