I just want to know why they made such a massive ESC and what type of plane/heli would it be used in except full size??

RE: Where to buy ducted fans
Ran the HET 90mm back on the bench with the10S battery. I only took the throttle up to about 80%, but it still achieved 3.1kg thrust. The current draw must have been getting close to 100A because I could tell the Turnigy 100A ESC was getting pretty warm (didn't want to risk damaging my CC 120A from flying debris). The power meter read ~2500W, but I was too nervous about the running fan to get close enough to read the voltage/amperage. With the proper motor I believe this little fan could produce as much thrust as the ChangeSun. As for the Electrifly motor I had in there, I think it's pretty well toasted. It was smoking when I shut it down.
Now if I just hadn't fried one of my 6S batteries testing the Haoye I could throw the ChangeSun back on with 12S and the 550Kv motor that just came in. Of course, if the Haoye hadn't blown apart I could test it with 10S and the 700Kv motor that just came in too. Oh well, I should probably put this project on hold for a while.

130A Watt meter came in from Hobby King.
Now to solder on some EC5 connectors.
How do I know that I will burn this thing out testing out a 56 Watt set up? LOL

Can the HobbyKing 45-70mm inrunner be worked to set cooling holes into the end caps?

If you'd like I could draw up the dimensions of the motor end caps since Ialready have mine taken apart.

...and even if you did drill holes on the front cover of the 45-70mm the Hayoe's fan doesn’t allow for much airflow.
At least the heli engines can suck in their own cooling air.
harralk, you didn't tell me you ordred one of those! Lets see it!

RE: Where to buy ducted fans
Harbor Freight had their laser temp guns on sale for $25 so I picked one up.
Will be nice to know the temp the motors are running at instead of doing the "hot potato" test like this guy. http://www.youtube.com/watch?v=NOFrr...eature=related
Harralk, listen two these duel Hayoe 127mm fans running in this A-10. Man that sounds good! http://www.youtube.com/watch?v=pALPC...eature=related
