Hi all ,

Just wondering what servo arms is everyone using on the BLS174 servo. Other than plastic ones supplied.
The spline on these servos is 8mm not the standard 6 and none of my aluminium arms will fit.

Seems to me a bad design by FUTABA.....you would think that they make all servos with the same diameter spline.

Does anyone have a logical explanation!!

Good Question,

No idea, and the 154 are the same, as I use the wheel for ailerons, never looked into the aluminum one.

For those interested servo arms used for model cars are 8mm diameter

What's wrong with the supplied wheel?

Gday Jon,

Nothing wrong with the plastic ones but here in Australia we get a lot of sunny days which makes them very brittle and I have a couple actually snap.

But, they're under the wings! Are you spending too much time inverted?!

No mate I think it has something to do with us been in the southern hemisphere he he he.
