Workshop's "Servo Killer" P&T Mount

This is a favorite Pan & Tilt mount that I make from two Hitec aluminium servo arms. I call it the "Servo Killer" in a tongue in cheek manner because with the right servos, it is very robust and has served well over the years.

Below is a build log so that other FPVers can make them too. I use Hitec HS-85MG or HS-5085MG and have never stripped a servo even after some pretty nasty crashes. But if you use a light weight servo, this mount will "kill it".

You'll need a three pack of 1/8" drill bits and some steel filled epoxy (I used JB Weld for the thread) in addition to the two servo arms and general shop tools.

Thanks Workshop, handy ideas.

BTW, love the 'remove before flight' tag on the lens cap. Processes like that make a huge difference to how long people stay in this sport.

Master class.

workshop: Very nice! I have a "fork" mount for my tilt servo, where it attaches on either side of the camera. Do you notice any reduced stiffness in the mount by going with an "open" design, where it's fixed on only one side?

This is an additional mod i have done that will eliminate most of any slop in a servo

even if there is a nice strong aluminum arm "L" shaped like yours

it works well

If you feel any slop in a servo for your pan and tilt

just drop , a drop, of ca, around the wiggly part , where the spline is entering the servo, and quickly spray it with kicker.

It will create a bushing, that will give you a slop free pan and tilt.

it will harden and you just need to break its bond with your hands before useing the servo again

don't be scared to try this because it works very well

I do this with all servo linkages as well

Interesting trick David... got to give that a try...

Twinturbostang... naw... this thing is a rock. I just have to make sure the pan servo mount can take the side loads... A bit of ZapGoo works well to take a bit of the wiggle out.

try it with a really old or crappy servo and see what I mean

it works well for the contol surfaces of the linkages as well
and will stop or prevent flutter

Hi Workshop, why do you use cut pieces of drill bit rather than screws?

thanks
Geoff

I wonder if even that's necessary with all the epoxy on there.

Good one!
Simple, effective, inexpensive, scalable, uses existing parts.
Definitely on my list.
Thanks for the how-to.

They call me Dr. Overkill... bwahahaha! Screws are usually not made of hardened steel! I want to be able to dig this thing out of a TwinStar hole and still have it work!

Nice job, looks great.
A video of it in action with voice over would have been KILLER.
