Another point, four of these will weigh around 125gm. try to keep your airframe light.

Hi All, I've been working with a Ladybird v2, and the little bug seems to have bitten. In the future I plan to build a quadcopter based on 35 size motors. My question is: would this speed controller be suitable for a quad? I'm still in the process of figuring out who shot john here. Thanks, Tom G

Thomas, this is a reliable ESC which I use in a number of models. It is versatile and allows for lots of adjustment. However, there are many features that you won't need in your application. I would be looking for a simpler ESC which would obviously cost less.

Can anyone tell me, what inductor that is?

Hi, Siffup. The quality of the answers you get will be relative to the quality of the questions asked. I struggle to understand what you are asking. Could you be more precise? Perhaps if you want to know the complete specifications of all components, the grade of solder used, etc, the best source of information would be direct to customer services who can access the manufacturer. This is more a discussion forum of customers and users. We don't make 'em - we fly 'em!

Have you seen the picture? The inductor with the 220 on, is it a regular 220µ*h? Wher to get the schematics for the 40a?
 OldFartFlyer 1457 points
Hi siffup. I can't zoom the pictures but I've made a bit of a guess and have checked over two of my five of these ESCs. The others are embedded in aircraft! I had toi use a magnifying glass. To be certain, I would have to remove the clear heat shrink to eliminate the reflections and slightly separate the components to better read the spec. I'm not willing to dissect. However, it appears to confirm yes, regular.

Hi, I´*m using 2 of these units. Does somebody know the which is the UPPER OPERATING TEMPERATURE for a continuos use, before the High Temp protection activates ???? Thanks a lot , your answers will be very much appreciated !!
 OldFartFlyer 1457 points
The specification is for 110 deg C, at which time the ESC will reduce output power. It will also cut power to the motor is it detects a loss of throttle signal greater than 2 secs. To keep the ESC operating cooler you can do two things. First, select a switching frequency of 16kHz (a programming card will not do this - use your Tx) Next, experiment with timing - if you are not always on full throttle then regardless of poles etc an outrunner configured to lower timing will generate less heat through the motor system provided your aircraft is okay with the slight drop off in power and you'll find your flights last longer.

5 thumbs up!
Wow, I am glad I bought this when I did! This is a fantastic speed control. I hooked it up to my new HK 450MT project and have had no problems. I haven't gotten the chance to really load it up yet, but it runs cool in hovering (test flights).

I deducted one star because it comes with no instructions. While you can build the HK 450 with T-Rex instructions, I wouldn't attempt programming the ESC with them!

Thanks again, HK!

Best ESC so far, will not use others for the time being. Very easy to program with the correct programming card.
