In my F-22 i have the Ntm 2700 and the 55a. Esc.

Did this nice trick I stole from gofpv. Don't think it will ever get too hot.

Very neat Maestro.

The delta mig runs at 100% throttle with 40c 2100 3s on 6x4 produced very little temperature in battery or motor. In July! 90+ degrees! I was shocked and mentioned it a few times on the mig 29 v2 and delta mig. I wonder if these turnigy trust 55 amp escs are better tuned to the motor than the 70 amp red bricks? I have timing set to auto on these. Scott, did you set timing to high? Anyone else find temp problems like Scott?

I wouldn't exactly classify what I described in my post as a "problem". Heat is obviously a byproduct of running high draw motors with high discharge batteries and perhaps not all batteries discharge at the same rate even if they are labelled the same, nor do ESCs all dissipate heat the same way, even of the same brand and A rating.

I have never had an ESC get hot to the point it shuts down or gets hot enough to allow me to use it to reheat my coffee. I guess we all have our parameters as to what is a "bit too warm" on our equipment, so if I think my gear needs a few minutes to cool off, then I give it a break.

I have my timing set to auto on all my ESCs and have the parameters set to the motor I use with each of them.

Quite often I will do 6 or 7 flights back to back in an hour with plenty of bursts of 100% throttle, so I expect some heat buildup in these situations.

While I have never used a Turnigy trust or for that matter any type of ESC (other than 3 from Grayson Hobby where only one has worked consistently) other than the Tower Pro, Hobby King SS and Red Brick ESCs, I have only ever had one that was a dud out of about 20+ I have used over the years. The only one I have ever burned out was due to some snow getting inside it and shorting out the ESC, so that would happen regardless of the brand.

I have been very happy with the performance of this motor and it's combo with the 70A Red Brick ESC setup on all my planes and for me the price is right.

Cheers,

Scott

I even put that beastly cooling apparatus into the breeze on this plane:


Even built a little tray for it to recess into.

My motor, esc and battery were barely warm after every flight, and all of them included several WOT runs. Several times on the forum I've heard how people find certain escs keep motors and batteries cooler. This is one of them, and my proton 60 amp Also. The hobby kings, and Grayson escs I can't say the same.

the Grayson esc"s are horrible all of mine get hot ! It's like there not rated rite or something. My hk ones aren't great but they are better than Grayson . I do use all the hk blue series ones with no problems at all. One of my favorites are the rc timer or hobbywing they seem to hold heat really well at low size. I was gonna try red brick but it has to many negative feedback s and are huge in size, but they are cheap

My 70A Red Brick only gets warm with lots of WOT and ZERO cooling (I haven't cut any holes in my FRC Su-37 yet).

Thus far I have had no problem with the Red Bricks, out of about 10 I have used, one was a dud, but all the others have worked really well. They are appropriately named, because they are a brick for sure, but those big cooling fins on the heat sink serve their purpose. I was flying my F18 V2 today attempting lots of high alpha, so I was constantly at higher throttle settings and very limited airflow through the electronics bay and it was barely warm.

I have also had good luck with the HK SS series of ESCs, I have used a 60/70A one with the NTM motor and it worked great, no heat build up whatsoever. I do use an external BEC with the bigger Red Bricks, but have found if I use one that is rated for 10A higher than what my motor is rated to draw that they stay nice and cool.

Like you I have had some issues with the GH ESCs and when you read through the GH thread, it appears ESCs crop up quite a bit with problems, I'm not sure where they get their ESCs from, I had three that I ordered in SMJV2 power packages, one of them never worked, no matter how many things I tried to program it, another one worked for 10 flights then packed it in, the third one did work and still works, but not a great track record for me, maybe just bad luck!

Cheers,

Scott

Very interesting thread. I'm always looking for good alternatives, just in case my favourite hardware is out of stock and I need some parts quickly.

For European customers I can strongly recommend the Black Mantis Series ESCs from Giantshark (UK). These are made by ZTW (China) and are sold under several different labels (like Mysterie or Hobbyking Blue Series... and you can even pay a three times higher price if you buy the same ESC with a Hacker sticker on it!). The built-in SBEC can provide 4 A current, which is great for 6 servo planes.

For my scratchbuild F-15 I used the NTM PropDrive 2700kv motor, 6x4 APC-E prop, 3s/2200mAh 25/50C battery and the Black Mantis 60A ESC. At full throttle this setup draws 62 Amps on the bench (should be about 5% less in flight). The battery gets slighty warm if I do a lot of high speed passes, but the motor and the ESC stay absolutely cold.
Regards, Wolfgang
