Default Servo Arms

Hi guys, I'm looking for servo arms with the recommended length of 18mm for my NX5.5

I am just rebuilding my heli and installing new BK 5001HV servo's, and in the past I've used SAB HD arms, as used on the bigger Goblins. Problem is, they are to strong, and take out servo gears on these midi size servo's.

Futaba/BK/generic 4 star arms are perfect thickness, but only 16.5mm, and the other arms I use a lot are Align 550/600 but they are 21mm

What arms are you guys using?

If nothing is available, I'm tempted to cut a very small 'V' in the SAB arms, so they have a weakness point to snap on in a crash.
TDRx2, Synergy N7/E7se/N5cTT, Align 450L/550/700e/700n, Gaui NX7/NX4, , Goblin 700/Black Nitro, Futaba 18MZ/ V-Control All on V-Bar's and S-Bus. #0095

I like the Dubro servo arms. these should do the trick. If not just search for the right ones as there are enough choices to cover whatever servo you have.
