Default DS415M elevator servo arm

Just put align ds415m's in my 450. There is no provided servo horn that works on the elevator push pull. I used the single sided arm on all 3 cyclics including the front/elevator but would like a proper arm to use the elevator push pull. Any suggestions?

They are a pretty tight fit but go in requiring only trimming just a touch off the bottom aileron servo mounting tab.

After sleeping on it I decided to drill new holes in the 450 push pull lever.to match the supplied arms. Worked out great.

I just used the long arm that comes with the Align 410 servo arm set;

Better than mucking around with the stock 450x geometry imho. You may have problems with your bx doing this.

Also found a few old HK H9 servos that had the right arms as well btw.

Cheers,
TomC

Sounds fine then. Just make sure that all 3 servo's work together at the same speed when you move collective pitch up/down quickly. Good idea btw. Thanks.

Cheers,
