HH Servo

[Sp3cia1-K]

I have always been impressed with how you stand by your product with confidence despite all the supplier issues encountered.

On that note I had another set of gears let go on the weekend, more to the point explode into several pieces while the rig was stationary on a flat rock. It was the gear above the motor output this time.
I'll send you an email soon John regarding another set.

Its a shame about all these gear problems because they have been good for me otherwise.

 

[JohnRobHolmes]

All Silver gears or black output gears? We stopped almost all gear problems with the last revision. Started snapping pins and wearing cases instead :lol:

My confidence is in serving the customer to their satisfaction. Even if the product isn't good enough, I can still offer a refund or
Store credit. Becoming a motor builder was such a hard process that customer satisfaction is easy in comparison. Of course the goal is quality products so the customer is satisfied from the start. That is where I differ from the Taiwan assembler. They say "don't worry, send bad products back and we will fix". I say "the products should work properly and not need fixing!" .

 

[Sp3cia1-K]

Yeah they are the all silver sets, well they were before some of the silver coating wore off The replacement gears that went were from just before you got the revised ones I think ;-)

You obviously know a fair bit about the spec of motors used in these servos, just wondering if I were to desolder the circuit board if these could be used for a servo winch with say a heyok winch controller or would you be needing to go for a specific brushless esc like a MSW? Just thinking outside the box

 

[JohnRobHolmes]

You would need a brushless sensored controller. The stock one would work fine, just replace the POT with two 4.7k resistors and it will power it like a winch.

So I had a warrantied servo die on me during the g6 last weekend. Are warrantied servos still warrantied? I'm still under a year from when I purchased the original one

 

[snapon boy]

I can't speak for JRH but he has fixed my servo/replaced it more than once.

 

[emmett751]

They're out of stock currently any insight as to when they'll be available again?

 

[snapon boy]

Email Holmes hobbies there was a post floating around that said there were build on request.

Again, thank you!

We do have inventory and plenty of parts to build them, but for the sake of moving forwards and ensuring our current customers have plenty of warranty support we have pulled live inventory from the site and stopped selling them down the distribution chain.



I'll have a few new samples of both brushed and brushless versions this week. We are also developing our own brushless servomotor and controller for a longer term project.

 

[snapon boy]

I can't wait to test out the new servos! Thank you JRH for being devoted to making sure our free time is enjoyed to the fulliest.

 

[802coma]

I'll be shooting you a email and I'll dig up my invoice. Seemed like the servo got real weak and was having a hard time going back to center like my first one (voltage reg) then the gears stripped out. Still got to pull it and such

How's this comin along? Making progress? Im lookin forward to seein what you come up with next for a badass servo.

 

[JohnRobHolmes]

Coming along nicely. Brushless version will basically keep the same specs, case looks might change some. We are working on the programmer interface, it might take a while to get that proper.



Brushed version hasn't been tested yet.

 

[Loehdingc]

Any chance you could ballpark when they'll be back in stock?

 

[JohnRobHolmes]

We have put down our first official order for the next version of our brushless servo. We have been able to bump up output to about 520 ounce/inches on 7.4v, and will name the new version the BLS HV500. Much time was spent to ensure the factory was on the same page on materials and quality, so that we hopefully won't have "improvements" made without our consent. I spent about three months going in circles over "improvements" that kept getting put into our samples.


Actual improvements made over the HV400 are practically everything. Increase in torque of course. Case material is now 6063, gear material is a mix of 4340 and 7075-t6, better case seals, and most important is RELIABILITY! We found that some of the prior issues are caused by case tolerances being off, pinching the gears when the case is tightened. We are still working on the programming interface. It's not really something a customer can use at this time.





To ensure that we can keep a constant quality and support with our servos, I'm going to china to work directly with factories. For some reason we have no problem working with any other vendors, but servos have been nothing but trouble! This will ensure we aren't dealing with middle men that screws up our specs, and that we can have a relationship with the CNC factories as well as the assembly house (assuming we don't assemble here).

This is Awesome news JRH!

Just the last couple days, I was going to hit you up and see what the good news on servos was!

Now, no need... [emoji106]

 

[firstpasstommy]

Man I have to say after buying an assortment of products from john for several years now, he's always responded and gave me hands down best service and parts available!! I'm very confident with anything that comes from HH.. I stand behind them 100%

 

[JohnRobHolmes]

Even when the first gen servo turns out to be unreliable and we lose enough money that we could have paid for a nice company vehicle, I got your back!



So who would be interested in old HV400 servos that run on the bench but have no guarantee, for $30 each? Still loosing money, but these things don't do us any good on the shelf.

If these are refurbished and not just somebody's returns, put 'em up on your site with full disclosure and see what happens.
