I've just finished up my ARC Strega but have no plans or set up info. The plane weighs 74 oz with ST 60,tongue muffler, Fox Spinner,13x6 prop. How far back from the LE at the fuse would be a starting CG point? I can get as much as 3 oz of tip weight in the tip weight box. Roughly how much tip weight should I start with? She's being flown on 66' lines .018 eyelet to eyelet. Any help would be appreciated.Thanks,PhillySkip
