Low Profile Servos and ESC compatibility

[CKU87 39]

Hey everyone!

I was looking for a new Low-Profile Servo for an upcoming build. I planned on buying the TSU06. Now I see that it says its not compatible with TEU302BK and TEU105BK. Since I am using a GT Tuned Motor, I was planning to use a TEU105BK ESC, which I have a lots of units lying around here.

What is the point here? The ESC has a BEC build in, but does that TSU06 draw so much power? What are my alternative options? Savöx 1251/1252? I doubt they would work. They have basically the same specifications...?!

Thanks

Why do you want to use such bad servo?

It is expensive and has plastic gears.

I can only echo this. Other than sentiment, theres not much logic to running Tamiya electronics full stop, unless its a shelfer, and if thats the case, the fact it wont run shouldnt matter.

Tamiya ESC's and Servo's are ridiculously over priced, and perform terribly in comaprison to the competition. But hey its your money

The reviews on TSU-06 isn't so great.  Ever since my Tamiya transmitter went dead, I am suspicious of electronic things from Tamiya. (The radio came with Terra Crusher. That was 20 years ago, but you can still find Tamiya ESCs without BECs)  They are outperformed by cheap Hobbywing 1060 (which has proper 6v BEC).  Now, even Tamiya is including Hobbywing 1060s in some kits.  I would just use 1060, it's only $12.

If you don't want to waste a lot of ESCs you already have, you can install a 6V BEC for $2.60.  You can put 20V on this thing, and it will still bring it down to 6V.  For the price of one TSU-06, you can get 10 of these and still buy 2 cheaper, faster, and stronger metal gear servos.

TSU06 has 3.5kg of torque. But it is fast: 0.09 second. And 25g is light.  

Savöx 1251 has 9kg of torque, at 0.09 second, and it weighs 45 grams,  

Here is something I ordered.

This Injora Servo has 14kg of torque, about 0.08 second speed, but it weighs 50 grams.  Even if the specs are 25% bloated, it would have 10kg of torque, 0.1 second of speed.  For $15, that's pretty good.

Thanks everyone. Yes, you are right probably, but I have this obsession to keep most things Tamiya and so far I had only used standard size servos, mostly Futaba - which I know and trust from good old days. Unfortunately, their Low-Profile servos are super expensive and not worth it for my mildly run cars. Admittedly, I never bought anything from brands like Hobbywing, etc. I just don't trust those brand being around for a couple of years and then disappear. Most of them are just the same but rebranded. But Futaba, Tamiya, Kyosho, etc. yes sure, anytime

Also, I am not looking for a super fast low-profile servo. I prefer servos that are a bit slower than these new crazy fast HV servos.

What is the BEC rating of the TBLE 02S? Might also go with a brushless combo here, using my NiMH packs.

There are many Chinese brands that came and went.  But as mentioned, Tamiya seems to like Hobbywing more than their own stuff.  My brand new 2024 MB-01 came with it.  We hear of problems that came from Tamiya's decision not to include $2 BEC function. But hardly any complaint on Hobbywing ESCs.  But of course, some people want to keep things Tamiya, and that's fine.  

The BEC on TBLE-02S has 6V 1.5A rating.  I have half a dozen TBLE02S, and I like them.

I've been using JX Servo PDI-4409MG for some of my cars and had no issues with it. it is under $20 from amazon. (low profile and 9kg.. speed is reasonable).
Also only Tamiya electronics(?) I use are motors... (brushed and brushless motors).

I know this sounds stupid and many people will shake their head when I say this, but the fact that I cannot mount the On/Off switch to its designated location already makes it unattractive for me. As I said, if you want to keep things all Tamiya, you really have a hard time.

But I think I might go with a brushless setup then and just use the TBLE02S. Thanks

I am in complete agreement on that. the Hobbywing 1060 is ok in my book though with the switch capable of being mounted to the ESC itself. That being said I have also cut off the switch and soldered on traditional switches for obvious reasons.

[Twinfan 2013]

Another fan of using a Tamiya ESC for the proper, screwed in switch on vintage re-res.

Otherwise I use the 1060 and mount the switch on the side of the unit.  Works great on GF-01s and other chassis' without old-skool switch locations.

It's Hobbywing that's stupid for making it so short.  Not you.

I've heard of JX doing weird stuff like that.  I've seen some youtube drifter claiming injora is better.  So I'm giving that a try.

Huh interesting... jx is definitely doing something wrong. maybe too much friction or some weird thing happening since it draws that much amperage...

I wonder if those switches are so short to be an easier fit in tightly packed models?

I agree though, if there's a place for an on/off switch I want to use it (and it definitely has benefits). Soon I'll be trying my first soldering in 20 years, but those small wires needed for such a switch (if I can find them)? I better get some motor/battery connections soldered well first. Actually considered a couple of TBLE's just for that. The TBLE however can't be powered with Lipo's IIRC, just now that I consider switching from Nimh batteries. Castle has a switch that might fit, but I'm not sure that price range is worth it for me just for that switch.

I found two problems with HW1060 switch wires:

1. They are too short to put somewhere on chassis

2. They are too long to mount them near ESC and have tidy wiring

I really think that switch should be integrated with ESC or has longer cable. Carson Dragster which is copy of HW1060 has longer cable and mounts on three (!) sides of ESC.
