I ordered one of these today to try out, based on your guy’s feedback. I’ve been running the Power HD 20kg red and blues with no issues, but the last one I got seems a little weak. Looking forward to see how this one works out.

Not sure why nobody including savox doesbt copy the savox 1283sg gear design. You will break the case before ever stripping a gear
..
Now if they just waterproofed it and made the case stronger.

Load bearing gear is still on bottom which is the typical design of all servos and why they all shred the same gear. Look at the first photo. You'll notice the applying motor gear is not on the bottom. It's going to a lower geared gear allowing it to take a beating without stripping teeth.

You will break this case before anything else
Broke the limiting tab inside the case....
Now I will say savox warranty sucks. They're currently trying to tell me just replacing the front case will save the servo however the potentiometer spun passed its program points and now only centers hard left. They currently dont feel that's manufactures defect.
Replaced with reefs triple 5 plenty of torque slow as shit, customer service sucks.
I Wish my local shop had Holmes in stock. Nothing but the best customer service from John's company.

No documented cases of PM gear failure yet, Savox on the other hand, I’ve got a box full.

No you're correct it's very unlikely with a PM I have heard a few cases of broken pro modeler gears but it still doesnt happen nearly as often as savox or others and he stands behind his servos like they're his children...

Yep, John has picked his gears for strength and reliability . Also why his cases are cnc’d in house

To be fair, there isnt a whole lot of us using them, so one would expect it to be lower.

Read the reviews in the RC Airplane world. John is a flier and that was his main market and target. I've searched, and gear or case failures are rare.....reason is hes on version 5 now, all improvements since the original 420 came out
That is a robust looking gear-train but more gears introduces more slop, manufacturing cost, wear points, weight, just make better gears, cases, pins and pockets for the pins, be done with it. "thumbsup"
Sorry to say, I've seen and heard more first-hand Savox servo failures, problems and non-existent warranty than any other brand, coupled with the noise they're known for, I'll pass thank you. Good luck with them, clearly your whole servo should be gone through and rebuilt after that kind of damage. "thumbsup"

I just have to say I like the PM 470 and its very powerful (and the build quality is truly great) but its only powerful in a vacuum. What i mean by that is the servo goes limp when it see's any resistance and it seems like some tweaks to the software might fix this. I'm not sure what the proper terminology is (maybe stall?) but if I hold one wheel and try to turn I can easily stall the servo. Now I'm guessing this is just a case of being built for flight and this likely being a safety measure. I also gifted one of these to my brother and he's noticed the same thing on his, we're both using them on 2.2 rigs.
Maybe I should shoot off an email to PM to let him know RC crawlers need all of the power and no sissy safety measures.

I found with my heaviest rig 11# Wraith, I didn’t have enough torque to center. I went to a 2290 and moved the 470 to a Bullyll and have my old 420 in my VS4, at about 7.5 # and dropped the voltage down to 6.0 as it was too fast for my liking.
I bind up the tires on my VS4 and never noted that issue. Curious as to what John will say.

I just sent John an email, he's usually pretty prompt in responding.
I just tried out the Savox 2290's on my BC8 8x8 build (it uses 2) and its no lightweight at 18 lbs, and that is a great servo. It will probably be my go to servo now for the heavy stuff.
Ok enough new expensive quality servo hotness talk, carry on.
EDIT: I got a response from John and he says it's likely down to the BEC which I kind of doubt but I'm willing to try what he recommended. He recommend running a 2S battery straight to the receiver while removing the red wire on the ESC. We will see....

I just realized I should clarify, John from ProModeler is saying that I might need to remove the BEC and run straight 2S and he said even stand alone BEC's arent up to the task which I cant really agree with, but I'll give it a try.

John has always said that. On his web site, he explains the whole reasoning.

Means I limited on 2S only? No way, I am no 4S now. [emoji23]

yeah, John has a serious dislike of BECs. Probably because switching BECs can be very noisy, and any servo (his included) will perform better with clean power.
I run my 470 on 8V directly from a Mamba X ESC in my Bomber and I've never stalled the servo, though admittedly I'm not one to wag the tail with my steering.
I just bought another 470 and Mamba X for my upcoming Yeti kit build and I expect it to be great in that truck too. "thumbsup"

I'm glad I'm not the only one!
