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. IG: crawlercanyon
Thanks for doing the 35kg pro. I mentioned It in one of your last videos. They have become my go to cheap servo and was curious if they made their claim. Pretty happy with it!
The rickety stairs on that stand was the first time I had ever cut risers. The staircase that's on the stand now is rebuilt out of the same pair of risers. It's still a great view from up there, a whoppin' 8 feet off the ground.
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!
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.
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
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.
@@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
Great vid and good selection of servos. Since we've mentioned amp draw before, and we've now seen another really high, is there a way to see numbers when powered by an ESC?
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.
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!
Any servo that will pull 8A is good for that. Now that we can get direct power for 60 bucks, the market for Rx-powered servos that 100% need an external BEC is dwindling rapidly. IMO.
I'm so used to seeing DS3225, it never ever registered to me that this one got a different number. The red case 25KG is the DS3225MG, the blue case 35KG is the DS3225SG, and this one is the DS3235 PRO. Would have been nice if they'd spent the extra 25¢ on a new case that says "45KG" on it.
Great review, amazon special 35kg servo is killer for sure!!! It does brown out some esc's....I'd like to share that I have modded a servo Y harness and I am currently running this 35kg pro servo in one of my crawlers on 3s direct power with some pretty surprising results. Absolutely crazy speed and incredible torque, as if it didn't already have incredible speed and torque. I've got a quite a few battery packs run through with no issues! Looks like this thing can handle high voltage...I'm living on the edge dude🤣. test that amazon special bad boy on 12.6, you won't be disappointed ⚡⚡⚡I've got a video or two up ony channel detailing the mod...
I'm starting to think every Amazon servo is under-spec'd. The fact that it can handle 3S direct without doing a Puff the Magic Dragon impression is impressive all by itself. Not having to use a BEC for it would sure be great.
@@CrawlerCanyon yep that was my whole motivation. That servo is amp hungry and the sidewinder 4 has no amps to give....and I didn't want to run another stupid bec. So I figured that 8.4 volts was close enough to 3s that it would be worth a shot to direct power that baby, if anything I thought I would get a good smoke show and that servo is cheap enough it wouldn't hurt my feelings or wallet to bad....turns out I was a little let down that I didn't get a smoke show🤷. I'm still running this thing though time will tell how it holds up.
That blue case is impressive, but you need to run a serious BEC to get the current to supply that power. At which point you might as well buy an inexpensive direct power servo. Edit: lol, you just said that.
I have not, because I'm generally looking at servos 32kg and up-- and really, I try to stay above 36kg. At the $70 pricepoint, I'm usually grabbing another Flash Hobby 60kg and pocketing the extra 8 bucks.
@@CrawlerCanyon Sorry, I was mistaken lol. I was a lot of your content after a very long days work and am drained most the time. I'm slowly switching my vehicles over to nsdrc from reefs since watching your testing videos, especially the one on the nsdrc 900. That thing is a beast.
I’m running the HW 1080 G2 on 7.4v @ 4A in my sendero SE with the standard element grabbers. 3S Lipo. What would be your recommendation for a servo upgrade that can be powered from the receiver? I say receiver because I wouldn’t even know how to direct power one 😂
@@CrawlerCanyon I just watched your review on the servo; looks great! Question though: you mentioned it’s backwards. How would I get it to, well, not be backwards? 😂
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.
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?
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 had a heck of a time trying to locate it myself, found what appeared to be the same thing from Zoskay RC but who knows. Thanks for the link, I was about to ask too! Thanks for another fun servo testing adventure @Crawler Canyon
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.
This is a winning formula that I can't use, as I don't run on 2S. And that's a realization that I literally just had right now. Wow. I didn't even feel it happen.
@@CrawlerCanyon I feel ya, I just have 2 trucks that are set up on 2s and do amazing, with direct powered Amazon servos. No BEC, my main (3s truck) has a NSDRC rs800v2.
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.
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.
