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. Will take a fuse width of up to 6.25in. 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.
