Otherwise I would have to build a pillar for the front scales to position the plane with the gear retracted. I don't have access to a large-scale balancer, and my fingers are just not that accurate, especially since I am near 24lbs! (and the Vanessa rig is just too cumbersome and hard to hit a steady state)
Thx DSA
I made my first few flights with a 130 CG with the gear extended and it seemed tail heavy (took quite a bit of down elevator trim). I've added almost a pound of lead to the nose to hit 120 CG, but haven't flown it there yet, so I too an interested in what feedback you get.
