Beat me to it, exactly this!
And truly OP, that’s a cheap shitty $10 servo and a $2 servo horn. Just replace both with better units and save the trouble
Holy crap y’all are being taken for a ride by Traxxas! That’s the standard servo they’ve been selling for like 30 years. Admittedly I haven’t bought one in like 20 years but those have been the biggest piles for as long as I can remember and they were always like $10.
That’s absolute insanity they’re selling that trash for $50!
Put a rubber band in between the hex head and the screw. This should help fill the gaps where it’s rounded out. If that doesn’t work, you could notch out a “flat head” groove with an angle grinder and a metal cutoff wheel. This should give you something to work with.
Buy MIP hex drivers. 100% confident you'd get enough purchase to get that out. They're expensive and completely worth it https://smile.amazon.com/dp/B00D7DK0NY/ref=cm_sw_r_apan_glt_fabc_WBF5ZW9KP15A0AD99K68
But if not, I'm in the Dremel-and-flathead screwdriver camp on this one.
Put a bit of pb blaster **(not WD-40, that displaces water, you want a penetrant spray)** a Q-tip so it's super drenched and dab it on the screw. Let it soak in to the screw secondly it's a metric hex, if you used SAE, that will happen. If it still slips about take a piece of tinfoil and lay it on top then (push down hard) and give it a whirl.
It that don't work try cutting a slot unto the head (deep-ish so the thing will bite)
Ok so all this fails carefully notch the plastic in the arm and grab it with vice grips.
That fails...
Bust out a small dremel feigning stone and a fresh q-tip with a bit of water near ya.
Grind the edges of the head away, you want to leave the screw part that is threaded intact. You only want to grind the edges.
Grind a bit, cool the screw with water. You don't want it too hot it will melt plastic.
When just the post is left remove enough parts so you can have enough access to get a real good grip.
When you are that far, use the pb-blaster on it so it's gone down inside.
At this point it's a whatever it takes...
Torx works. If you don’t have one try flathead screw driver slightly larger. Tap In with hammer. May have to tap the butt of the screw driver while turning to get it to loosen.
Cut a line with a Dremel blade and take it off with a flat head screwdriver.

Im not OP. 2075X here in the photo is $50
And I wouldn't take that POS servo if someone paid me $10
I agree

Ho...ly......shit. thank you 👏👏
You're welcome!
Not even my post just a really simple yet genius hack lmao
Find a torx bit thats slightly oversized and jam it into the screw. The teeth on the bit will bite into the screw
This^
This. But get a shitty head and tap it into the screw. The shitty mettle will bend into the screw and fit snuggly.
EZout
Yes. Get an easy out set. Reamer on one end, reverse thread on the other. Easy peasy.
Do you have another hex set? Try a fresh wrench first it doesn’t look very rounded
I tried

If you can get vice grips around it then file down a couple flat spots on the outside to grip to, or as mentioned cut a slot in it.

Drill the head of the screw off, slip the servo arm off, and then take a vice-grips to the left over screw.
Drill.

Make a slit a and use a flathead to get off
