HH Servo

[JohnRobHolmes]

It has two pigtails, one for the RX and one with a JST plug for power

I want one!

SHV500 Servo - Servos - Electronics & Wiring

The rundown:

The BLS SHV500 servo is designed for R/C Rock Crawlers, but at home in any vehicle. It is powered directly from a 3s lipo, eliminating the need for an external BEC! Clean up your wiring, gain space in a tight rig, and enjoy near silent performance with the upgraded brushless motor and circuitry.



FEATURES:

Water-Resistant Alloy Case
O-Ring Seals
All Metal Gears
Brushless Super High Voltage motor
Upgraded N38EH 200c rated magnets
24cm servo lead
24cm 12v power lead with JST plug
3s Lipo compatible (16v max)
1 Year Warranty
SPECIFICATIONS:

Weight: 73g
Dimensions: 41x20x40mm
Spline: 25 tooth (Futaba type) M3 threaded
Torque @ 11.1v: 32.4 kg/cm (450 oz/inch)
Speed @ 11.1v: 0.10 sec
Torque @ 14v: 37.5 kg/cm (520 oz/inch)
Speed @ 14v: 0.08 sec



I engineered the motor to have about the same output as the 8.4v version, but the speed increased quite a bit. We have been running our prototypes for about 6 months now. It's weird not having a BEC on the rig!

So what you are saying is, I should start running 4s

[JohnRobHolmes]

It'ss a bit too high of voltage on a fresh charge, some internals wouldn't like it. Designed for 3s only.

[XSRCdesign]

Awe.. Shucks. I have a ton of 3s packs anyway...

Got one ordered @ The Crawl Space for my upcoming sporty build!!

Okay- dumb newb question.

On the HV500 the HH web page says it is 2s (8.4v max) compatible. So can you use this servo with a 3s lipo? I'm guessing I can just limit the output voltage of the ESC with the Castle Link to 8.4V. Right?

The kids trashed the stock servo in the Ax10 Deadbolt, hence I need a new one. (And I might get a slower motor too.)

[JohnRobHolmes]

You can use the HV with a 3s lipo, but you will need an external BEC to handle the power. The external BEC (Castle BEC) will regulate the voltage to 8.4 for you.

[rhodo]

Excellent, thanks John. I'm starting to get all this. (I got the CC BEC from you guys.)

Now I just need to compare your Crawlmaster and Torquemaster motors. Expect another question in another forum later.

[JohnRobHolmes]

Ill go ahead and help you. Want smoother crawling, get the crawlmaster. Want more torque, get the TorqueMaster. Most customers that try both never go back to the torquemaster, but nobody has ever told me they prefer the TorqueMaster except for a few competitive guys that wanted extra punch in heavy or tall tire rigs.

[rhodo]

Thanks John!

Has anyone found a suitable gear set for the HV400? I have one with a few broken teeth.

[snapon boy]

Yes it uses savox gears. Which ones I don't remember but I'm sure someone will chime in.

I have an issue with my HV400. When my truck is on the ground, the servo just twitches real fast and doesn't turn at all. Off the ground, no twitching and it turns. This is the 1st time out this year but worked fine last year. Running 3s, Trailmaster BLE Pro, Puller pro 3500 and ccbec at 7.4v Any ideas?

Anybody who wants a new middle pin, email warranty@ with the following

Name
Shipping address
Proof of purchase

Be sure to let us know you want an updated middle pin in the email too!

I received an email from Justin on 6/23 saying a pin and some o rings were on their way. Awesome!

...however it's 7/5 and haven't seen anything.
Can you check on this John?

[JohnRobHolmes]

They were sent first class mail, would have left town the 24th. Since you asked it will probably show up today or tomorrow. If it doesn't, shoot Justin an email and we will reship some.

Thank you sir, I'll let you know.

Greetings,

Can someone please tell me what gear set I can order to fix my 400?

Thanks,
John

[snapon boy]

Since John didn't chime in email Jonathan at Holmes Hobbies he should be able to fix you up

John, the email for updated pins is warranty at holmeshobbies .com, correct?
