I received the Flyduino CP HL this week along with ESC's and motors.
But first I'm doing some research on this next project. I think I read from Jussi somewhere on rcgroups that he placed the ESC's under the motors. Resulting in maximum cooling and minimum interference. I've got the same setup on a Xaircraft X650 with good results.
I can see the advantages of placing the ESC near the motor but would like to see some examples how you guys mount a esc on the FCP HL motor mount. I think the big problem is the Cap.
