Great Planes Spectra ARF Sailplane
Put together a GP Spectra ARF.
Placed a MA 3.5:1 gearbox on the nose and 12x8 folding prop as well. Rest of airplane is stock and balanced in the midpoint of the recommended CG.
Question is there appears to be, after mounting the gearbox and prop, an extra degree or two of down thrust, when compared to the angle of the firewall.
Should this be corrected prior to first flight or will be ok?
Am a bit concerned, especially at take-off.
Thanks in advance.
