Promodeler V3, nope V4
 

Well I went to order another V3, and wouldn't you know it, it has been replaced by a V4. From the description...
420oz-in v4
You're looking at our newest S420 servo, the S420v4. While it looks a lot like the S420v3 it replaces, just like a Porsche 911 looks similar year-on-year, our engineers also apply what they've learned to make iterative improvements. For example, in going from v1 to v2 we improved the gear material (from brass to steel because steel wears better). With the introduction of the S420v3 we went to massively larger steel gears (and a finned case for better cooling) because top modelers were abusing servos like nobody else on the planet. Using what we learned results in better servos for everyone. Now, with the S420v4, we've done something else never before seen in aluminum servo cases - hard points. Pressing a harder material (brass inserts) where the steel gear shafts fit the aluminum case enhances durability and results in greater precision, which is important.

Can't say I have had any issues with my V3, but I guess progress happens. So its in the mail, when it arrives I'll be taking it apart to check everything is water tight so I'll see if I can get some pictures of the internal changes.

Go figure, I just ordered a V3 last week. I'm already running a V2 without issue.

Re: Promodeler V3, nope V4
 

V4 is 25 spline output?

Re: Promodeler V3, nope V4
 

Yup, 25 spline. Since this is up it's worth noting that even though I ordered a v3, I received a v4 those months ago. John even sought me out on here to let me know that.

Now I've got a year old gen 2, and a couple gen 4s. All funtioning flawlessly, which is saying alot since I seem to destroy most servos. Only complaint is I want a couple more, but there out of stock.

Re: Promodeler V3, nope V4
 

To give an idea of when they will come back in stock might be a while. I ordered mine on 12-10-16 and Still on the wait list for production release.

Re: Promodeler V3, nope V4
 

I'd love to see a 700 oz version come out but he says he'll never build it due to limited demand.

Re: Promodeler V3, nope V4
 

I'd like that as well and would pay for it. I payed for the 420 and can't get that so....

Re: Promodeler V3, nope V4
 

My old link to the v4 now shows v6 is call for availability...

Re: Promodeler V3, nope V4
 

I saw that. I wonder how many of the new versions are actual improvements versus cost cutting measures for more profit.

Re: Promodeler V3, nope V4
 

They have a new Site also.
Just Promodeler.com now

Re: Promodeler V3, nope V4
 

I pm'd john himself about availibility of the v4 a few days ago as I have a build that needs a servo (don't we all though). Without going into technical/business reasons, which he asked politely that I not share, It's looking like mid february will be the next batch of v4's.

I shall wait patiently till then rather than purchase either an inferior, or much more expensive, servo since the ones I already have work flawlessly. Just the other day I bent a vanquish steering arm and ripped apart an rpm revo type rod end with the oldest gen 2 during a collision with an icy snow bank.

I could make a pile with all the broken front end parts that v2 has outlasted. It's like that old snap on hammer that you take for granted how many things it has reshapen or broken in its life.

I too have pestered john about making a 650 oz/in servo. He currently feels that the market is too small, and the end result too expensive at $150+ to make it worth the hassle to design and build such a servo. He didn't say it would never happen though, so if you too dream of a bombproof 650 oz/in servo then let john hear about it. If we show enough interest then it may eventually happen.

Re: Promodeler V3, nope V4
 

His past updates have all been improvements to the design and hopefully that will continue. I've also seen typos and errant pages on his sites so we probably shouldn't read too much into an updated version number on an old link.

Re: Promodeler V3, nope V4
 

I'm ready to order my 4th promodeler servo. Hope he gets them built soon. I've got a friend that's ready to order one too after seeing how well mine are doing.

Re: Promodeler V3, nope V4
 

None, John can and will give you facts not fiction.... finest 90.00 I've spent in RC.......https://uploads.tapatalk-cdn.com/201...ede607619b.jpg

Hang up and Drive

Re: Promodeler V3, nope V4
 

Yup, I have one in my wraith, bomber and scx10ii. All are great. Would like a little more torque but their durability greatly outweighs that.

Re: Promodeler V3, nope V4
 

Mid February? I don't mind waiting 60+days then shipping time if the servo is as good as everyone says.

Re: Promodeler V3, nope V4
 

Is that plastic in the middle of the gear? :shock:

Re: Promodeler V3, nope V4
 

Metal pins meathead


Hang up and Drive

Re: Promodeler V3, nope V4
 

Metal pins, but a plastic adapter. What goes in the rectangular hole in the plastic piece?

Re: Promodeler V3, nope V4
 

That slot is for the potentiometer drive. There is literally no torque on that part. All the load goes through the bearings, which aren't shown in that pic.
