These are almost polar opposites, IMO. One makes their numbers and one does not.
Running the gauntlet today,
ANNIMOS DS3225 PRO at 7.4 and 8.4 volts
NSDRC RS700 at 8.4, 12.6, and 16.8 volts.

My research may very well suck, but did you ever do a test with the RS700 V2? Those numbers look impressive compared to heavy hitters like the reefs smart 1100.

Thanks for sharing this with us, from watching the Power supply current display, I think the NSDRC has an internal overcurrent protection, have you tried to dial it slowly? Thanks!

Very interesting, having a mix of Holmes, NSD, Amazon, Hitec, and Savox. The servo wars are getting crazy. In comp trucks I have a Holmes 500v2, NSD 500B and RS700 and find all of them more than enough. Of course you can stall any servo out in the right spot but a little wiggle and just about any servo 500oz or up will come free. However I am trying out some of the blue bird servos on a recommendation from a friend. So far the speed and power per $ is very impressive. The 3507 specifically in my bomber has surprised me for a $70 servo. And have the BLS-H51B-V2 to test in my Ryft, hoping that the helical cut gear holds up to the harder hits. But possibly ones to test out if the need arises. Keep up the great videos!

Great test. I run the RS700's in my 4WS rig. I would say I noticed the lower torque of the 700 but I'm comparing it to my RS800 V2. I ultimately did go a shorter servo horn in the rear, but I suspect it is due to how I used a Y plug from the JST tap plus I was lazy and didn't clear the lead free solder off the XT60 when I installed the JST tap. You shouldn't really mix leaded and lead free solder for long term connections. The solder joint goes gray and cloudy, and gets brittle. You see this play out in guitar amp repairs in modern RoHS amps. Anyhow, I wanted the lighter weight low pro servo in the rear and I'm still glad I purchased the RS700. There are not many options in direct power low pro servos. After my experience with a glitchy SHV650, I wasn't interested in one of their low profile options

@CrawlerCanyon Жыл бұрын

When I need to tap that JST onto the XT60-- which is pretty much every time-- I've found it's a whole lot easier to just cut the OE plug off and start fresh. I wouldn't think the factories "over there" would have all gone lead-free, but the solder they use is awful. Kester 44 or nothing. I finally got the SHV500 replaced, so Jake can be nice and quiet. Almost all of the noisy boys have been purged from the fleet-- well, at least "relocated" to places where noisy don't matter. Like anything Arrma.

@Andy_Yates Жыл бұрын

@@CrawlerCanyon Yeah I should have just started fresh but sometimes I get cheap and lazy, which is a terrible combination sometimes 😆 Since I was soldering to a 1080, I would like to think Hobbywing isn't being shady about their RoHS compliance. If a product is going to the EU or UK, it has to be lead free. Who knows with the other Amazon brands, but you can tell right away if you add leaded solder and the joint grays after being shiny

@CrawlerCanyon Жыл бұрын

I think what I'll have to do is "expand" the test rig so I can include a 1080 and a receiver, so I can do some "really real world" pulls-- see what something like the amp-hungry PRO will do when confronted with the harsh reality of 3 amps. I happen to have both of those things-- I just need to finish building those 50+ lil' Christmas houses so I can get back to properly goofing off.

If you were running off of a typical ~3A internal BEC, I'm not surprised. An external BEC is pretty much compulsory with peak draws that high. The non-Pro version draws less than half the amps. Coreless motors are power hungry.

It's a little disappointing that NSDRC inflated the numbers. Totally not disappointed in the servo itself. When you're committed to a hard body, you gotta save those above cg grams somewhere.

Sorry for my ignorance but what can be the effects of a servo that draws that much amps?

@CrawlerCanyon 6 ай бұрын

Least case scenario, you get a brownout as the servo draws all of the power from the BEC and you basically lose control of all vehicle functions for a moment. Worst case scenario, the BEC dies.

@@marckjato yeah, you're never going to see an issue from any of the huge ESCs for truggies and whatnot-- MAX6, Mamba Monster, etc. Direct-power servos for those kinds of rigs are not super common, and are also (usually) super expensive, so a big BEC to run big servos is pretty much standard.

How hard is it to take servo that's not direct power and make it direct power? Do you just take the wires for power remove them from the connector and put a connector on those?

@CrawlerCanyon Жыл бұрын

You can do it by building a Y-harness, with the red wire for the servo going directly to the (+) terminal on the ESC connector. But the thing is, RX-powered servos have no internal voltage regulators, so as the battery runs down, the servo will get slower and weaker. So caveat emptor.

I know that some of the big scale stuff uses two steering servos, one per wheel. I wonder If I can make a custom SOA mount to fit two servos... would only need half the torque per servo... and then figuring out how to get the channel mixing and endpoints to work... but definitely interesting.
