TBS Source One HD 5 Inch Spare Arm (2 pcs)

Great spares

Bought as spares, haven't needed them yet thankfully! The pieces look to be great quality as always though!

HD vs V4 - there is a difference

Images shown for this product still show the V4 arms, the new HD arms are slightly different. It seems they introduced a stress concentration near the attachment point for the arm making the HD arm weaker than the V4 arm despite the HD arm being wider. I flew two packs, crashed in grass from about 15 feet and snapped this HD arm clean off.

works as advertised

these replacement arms are quite wider then the original, good thing i bought 4. again thanks for the prompt service,
