A while back I ordered a set of "Futaba" servos on Amazon but they were knock off. (I did send a notice to Amazon and Futaba about trademark violations, but got no answers.) Funny though, all of the servos worked fine and were actually quieter!

So now I am searching Amazon, Ebay, etc. and have found a number of "knock-offs" for a few dollars cheaper and in some cases even more expensive. Hobbywing's MSRP is $(US)21.99.
So, the word is "caution" when buying these even when the ad says "Hobbywing". Check the photo.
Upper left (Fake)😠: The Ebay ad says"320A RC Car Hobbywing QuicRun 1060 60A Brushed ESC Electronic Speed Controller". The signal wire are plugged into the esc (on the real one they are hardwired.
Lower left (Fake)😠: Walmart online "Hobbywing Quicrun 1060 Brushed Esc Waterproof / Speed Control 1/10 Cars / Trucks R8D7". Look at the cooling fins (heatsink) the run perpendicular to the real ones. Even some of the power wires are different in color.
Right (Real)😊: From the Hobbywing web site.
This is only two instances that I noticed.

I have two Mtronics on one burned out (yeah, fire and smoke on the water). The Mtroniks has a slight advantage being it will run the motor with the prop barely moving to to point where the boat does not even move. The 1060 has a great slow speed where one can still watch the prop turn.
To me the 1060 has a big price advantage, last time I looked it was almost half the price (here in the U.S.) of the Mtroniks and that was comparing a 1060 60A versus a Mtroniks 20A.
I'm completely sold on the Quickrun 1060's.

Whilst I'm using HobbyWing ESCs in my own builds I did buy a ready built Club 500 with a brushed motor and Viper Marine ESC which was working Ok initially but after being tipped upside down a couple of times during racing I have an intermittent fault where the throttle and steering are reversed! Not the ESCs fault as it got wet but time to change for a Quicrun I think.

I have spent the afternoon fitting them after cutting one of the red wires. I have 8 channels working and so far so good!
Thanks for all your help and advice.
Ps When taking out the old Vipermarines I found I had in fact disconnected one of the red wires, so it couldn't have been that problem

With ESCs the term not safe for LiPos, as I understand it, just means that a safe lower limit cut-off for LiPos can't be set. Volts are volts whatever the battery type! A separate low level battery warning unit could be used. Having said that I only use ESCs (mainly HobbyWing Quicrun and Seaking where you can set the low-level cut-off dependent on the battery type.
As far as the BEC goes you should cut one of the red wires otherwise the voltage will be doubled and the receiver won't like that! 🤕

I have looked at the Quicrun 1060 and 1625. As I am using 3s lipos the 1060 is the one I have ordered - I notice that the 1625 is only good for 2s.
I am using the Hobbywing brushless esc s in other boats with no trouble, so hopefully no more burn outs - and no more Mtronics!.

I'll check later, I realise the tax implications to Brits buying in Europe and vice versa!

They also do a 160 amp version which has a smaller cooling fin.
So far I have personally not had any problems, nor have I had any buyer returning for replacements, they can accommodate, by a simple switch, Lipo and NiMh battery packs.
If you shop around on ebay you may well find them on sale at a lower price.
I have just copied the first listing that I found!

I can only find 'Hobbywing 30A Brushed Speed Controller Eagle-30A'. Is this the one you mean?
The Hobbywing I am thinking about only seems to make brushless esc s.
Thanks

All was wired according to manufacturers instructions.
I had thought of removing one one of the red wires but considered it unnecessary - perhaps I should have done.
I didn't know that Mtronics were not lipo safe so it seems the solution is to change to the T10 range - thank you for the tip Rowen!
Any suggestion as to how to get rid of the most unpleasant stink?😀

The standard Mtroniks brushed ESCs are not LiPo safe and thus burn out. The T10 range is though.
Solved the problem by moving to Hobbywing ESCs that work with LiPos. Also more economical.

The batteries were connected and the system switched on as was the Tx. The Rx was showing a green light indicating it was bound and the esc s were showing the correct lights.
Neither of the motors were turning.
Suddenly one of the esc s starting hissing and then produced clouds of white smoke. I was only able to stop this by disconnecting the battery (the on/off switch had no effect).
When the smoke had cleared I saw that the wiring and part of the case had melted.
I had exactly the same thing happen to another boat with 500 motors, wired in the same way and with the same esc s, about two years ago. I have since replaced the esc in this boat and it has been working ok ever since.
Has anyone had any similar problems?
