Good ESC. Bec slightly too weak

Nov 21, 2022

The price is great and I have had no problems with these conrollers in the past and I use a few of them. But the Bec is only 5Volts and not really stable especially you have more than 4 Standard servos in your plane. I see the Voltage drop of the RX drops sometimes down below 4,3Volt at least for some seconds!! I recommend highly to solder an external 6V/6A UBEC Parallel to your power supply connector. The ESC comes without connectors und the Motor wires are really short. Be careful about the BEC otherwise a fine product with a very low price.

Sehr gut - funktioniert einfach

Nutze den Regler RED BRICK 70A zusammen mit einem Brushless SK3 5045-660 Kv in einer RASCAL 80 mit 4S Akkus 3800 oder 5000 mAh und einer 15x8 Luftschraube.
Der Regler tut einfach, was er soll, ohne große Einstellarbeiten.
Wie vorher schon ein Kunde geschrieben hat, sollte der Servoweg für die Motordrossel auf 110% eingestellt werden.
Mit dem Regler gibt es keine Probleme !!!!!!!!!!!!

Product came when advised and was well packed.
Speed controller works superbly and runs quite cooly, only just gets warm when pushed. A good buy.

I bought the Red Brick 70A ESC to install in the HK 1800mm Cub, powering the excellent Propdrive 35-48 900KV motor. I am very pleased that I chose this ESC in preference to some of the more expensive options as it has turned out to be a very good buy indeed.
Simple, robust and easy to program using a transmitter, once you familiarise yourself with the different tones - I recommend this excellent tutorial when setting up your new Red Brick;

I did remove a portion of the heat shrink covering over the heat sink fins to aid cooling, which appears to be a common practice - easy to do and effective.
All in all, an excellent choice of ESC at a very affordable price. I thoroughly recommend it for fixed wing models.

With a lot of promising reviews here, I got two my newly acquired (and beloved) Duelist. One died on the second flight, causing a stall and irrecoverable spin which turned it into a big pile of match sticks.
The more disturbing news is that the full throttle current draw for my setup was a mere 50A per each motor and I went to 70A just to be on the safe side for this specific plane. That seemed not to work at all!
