I don't own a Mac (and probably never will because I'm a cheap bastard), but if I did, this is the first thing I would do:

Well....I ordered my new servo for my soon to order Tekno eb48 2.0. I was gonna get an AGF-RC servo but I went with the Power hd B4 servo. For the $66 price tag you get a pretty good servo. Power hd upgraded the gears in them from titanium and aluminum gears to titanium and steel gears. So it should be strong enough. I had to email Power hd to confirm this. I like that they come with a 2 year warranty. Should serve its purpose as I am only a casual club racer.

Certainly a good servo for the price....what I dont get is that people actually think titanium is better in a servo...well have a look at this then---last post on the site >https://www.robotshop.com/community/...-5980/15939/11

I lucked out....my Power hd B4 servo that I just received does in fact have the titanium and steel gears. I emailed Power hd the number on the middle case and they looked it up. So hopefully it will be strong enough for my Tekno eb48 2.0. Time will tell, I think it will be.

the more stages of gears you have in a servo the higher the inertia and friction gets. the higher the inertia the more difficult it is to stop and start on an exact position. I think some titanium is as strong as some steel. lighter gears = less inertia.its a premise based on science. there are allot of ifs in the statement though which could leave it firmly in the realm of marketing but then again...
I like the AGF. its precise fast. and positions well with plenty of torque. it has not made a drastic improvement but I like it, it works, and its durable.

I have many JX servos working really well. But this in particular did not last a race.

would this fit?

I just checked my race log and after 39 race days (plus lots of practice) I finally had my first issue with the A80 in my SCT410.3
My son just got back into racing after taking a 7 year break, so he's a little green and hasn't been the cleanest driver so the past 7 of those race days were driven by him exclusively. Anyway, last race day I noticed that the servo was locked up after I turned off the truck. The servo worked perfectly fine, but just wouldn't let you turn the servo arm with no power. Then last night I noticed there was a ton of play where the wheels would wiggle until the servo was locked up.
So I just pulled the servo apart and found that the main center pin had snapped just above the bottom gear, nothing was stripped, I just needed to replace the broken pin (1.6 x 13.5mm), fortunately they include these pins in the replacement gear sets! I have opted to keep using the original gears for now, after re-assembly I confirmed there was no slop anymore and the servo arm can move freely with the power off.
