Thanks for the feedback I feel much more confident.
BTW - I see in the manual it says C.O.G. should be 75mm from leading edge. From what I see here, it should be 15-30mm behind the servo wire, which translates to at least 90mm from leading edge. Should I ignore the manual?
yes, ignore the manual
moving the cg back results in better gliding behavior, but will cause instability.
iīve tested different cogīs, my skywalker weight: 2100g
original: gliding angle 1:brick, need much aileron up to get an flyable angle, but react nervous if underspeed/overspeed
0-25mm behind servo wire: getting better every few mm
25mm: optimum of gliding angle, speed spectrum and stability
25-35: angle getting better again, but sensible at underspeed and less selfstabilisation.
these measurements may vary at different weights an pilot skills, but 25mm will be a good start for your first flight.
my actual set is 30mm. issues at underspeed donīt matter in my case, because i use the optional flaps.
