Brushless Motor Comparison Testing

[FE Wannabe]

Joe,

As always I am very interested in your test results.

Glad to actually see a picture of the new FighterCat ESC, I am very interested to see how it performs.

I do have a few questions about it, if you haven't been sworn to secrecy.

Is the ESC a single board design?

It appears there is a finned heat sink on one side and an water cooling block on the other, is that correct?

Which side has the FETS on it?

I had a great time, as always, running at your place last Saturday. You are always very gracious.

Happy Testing..........

Brad

Where is the pic of the fightercat esc? Can't seem to find it? Guess I'm goin blind in me old age!

No secrets here. I am not sure Ben is going to deal with them however I believe I will if the tests work out. You are correct about the water cooling on one side and the finned heat sink on the other. I put the dual 12 VDC fans on for increased cooling.....so easy for you Mr Surplus Fan Man!

The FETs have a gray thermal conductive sheet that contacts the water cooled side which is the way it should be. There are three 470 mfd 50 VDC Rubycon YXF Caps. I am installing 4 additional of the identical caps but I could easily increase that to 6 or 8 if required. My testing will reveal this since I have temp thermistors on both the fets and the caps into the EagleTree.

I also have a unique BEC that does not need a separate battery pac. (Remember the ESC is opto) It connects to the balance charge plug of any LiPo pac you are using and actually velcrows to the bottom of the 2.4Ghz receivers I am using so it is a real clean package, all in a waterproof balloon.

I sent you a PM on the video goggles for your Recovery Boat. You are welcome to come down to test them out. The LCD is impossible to see in sunlight negating the value of your wireless video system. Get those ducted fans installed!

Joe,
Thanks for the info.
I can see this ESC getting the Joe "Copper Cooler" treatment soon, but with all the stock cooling it may not need anything additional after all. You could always do that chilled water thing that you do so well.

I will check out the link you sent me on the video goggles, I may have to come down and test them out. I may have to get a 5.8ghz wireless camera system instead of the 2.4Ghz because I had too much interference to get a good picture when I tried it at your house on Saturday. Time will tell.

The EDFs are being picked up this afternoon. I am going with 2ea 89mm fans on 2ea 10L 540 Feigaos on 3S or 4S and reversing ESCs with a stick radio, so I should not only have some serious thrust but also be able to spin it like a tank!
I may be able to get that PVC rescue boat on plane, if not turn it into one!

Brad, Before you buy the 5.8 sytem see me. I do not think that will entirely solve your problem. If you do thing 5.8 is the answer, I have one you can test before you buy. Your main problem is flea-power. Your output is only 10 mWatts which is WAY too low for wha you are trying to do. I have some 100, 250, 450 and 1,000 mWatt units you can test also. I also have 1.2 Ghz equipment and some 2.4 Ghz "secure" transmitters that operate at frequencies slightly above and below the normal wireless 2.4 band to eliminate conventional WiFi interference.

Just FYI I am operating my wireless units at 1000mWatts on the boats with HiGain receiving antennas!

Jim,
The picture is at the bottom of post 30. It is even bigger than the Turnigy Monster 2000! I am hoping it works better as well.

Joe,
My 2.4Ghz camera was working fine for me at my work. I had walked about 420 feet away from the receiver and the picture was good as long as I wasn't moving the camera quickly.
The problem may have been the 9V battery I was using to power the camera. It may have been low on juice. I will have to try it again using a fully charged 2S lipo to see if it works better.
If not I may have to attribute the problem to 2.4Ghz interference. I have more testing to do.

A 1 watt transmitter! Do you need an FCC license for that bad boy?
Tune in Tokyo......

The ESC weighs 500 grams and is 150 x 60 x 29 mm without the fans I added. It will handle 10 S with a constant current of 150 A with a 10 sec max current of 200A. I think the additional caps are a must on this beast. Looks like the perfect ESC for the lower KV, motors and specifically the Leopard LB5692 730KV motor.

I am going to be testing this as a matched pair with my new BEC. (again, required since th ESC is (OPTO). Set up is 3 ways, USB link, program box or ESC beeps.
