CG ADJUSTMENT
CG adjustment is done by changing the location of your hang point along the keel. The farther forward
your hang point is, the faster the wing will trim, the less effort will be required to fly fast, and the more
effort will be required to fly slow.
On the Combat 12T, the hang point position is adjusted by repositioning the hang bracket along the keel
tube.
SPROG MEASUREMENT
The Combat T uses inboard and outboard sprogs in combination with one transverse batten on each
sprog. Each transverse batten spans two top surface battens, so a total of eight top surface battens are
supported. The sprog system is the primary component of the system, which provides pitch stability.
The function of the system is to support the trailing edge of the sail at low angles of attack, and thus
provide a nose-up pitching moment. The sprogs are adjusted at the factory to their proper settings.
The sprog angles should be checked regularly. This can be done with any digital electronic angle meter
as follows:
1. Fully set up the wing o a reasonably level surface.
2. Rest the keel tube on a support and using the angle meter as shown on the photo set the angle meter
to zero. This angle of the keel tube has to be maintained during further measurements.
3. Fully open the sprog access zipper. Place the worktop of the angle meter under the middle part of the
sprog so that the entire worktop surface of the angle meter touches the sprog.
The scale of the angle meter will show the sprog angle.
The sprog measurements for combat 12T should be as follows:
Main sprogs: 8.5 deg. Outboard sprogs: 9 deg.
