CG Scale Large Support Arms

SoaringUSA is pleased to offer the new Portachiavi brand Large Size CG/Scale Arms! These new, larger support arms are great for scale, semi-scale, or any large model airplane with a wide fuselage: for example an ASW or DG1000.

These new arms are offered separately and are a plug and play upgrade, it is NOT necessary to send in your Portachiavi  scale to re-calibrate it. 

Simply unscrew 4 screws, remove the old support arms, insert the new ones and screw in again.
