Hello folks, I am getting ready to install the Electronic Speed Controls (ESCs) that will power up the six brushless motors. For these I will be using a set of Exceed RC “Volcano/Proton” 30 amp ESCs (Cat #07E04) that I got from Hobby Partz on sale for about $14 each (You can also look up “Hobbywing Pentium-30A” which I believe is the same ESC or “Volcano-30 (07E04)”).
I am told that these ESCs are a great value and from what I see so far I can’t disagree. I am using 30 amp ESCs in leu of 25 amp units so that I have a larger margin for upgrading my motors to a bigger size should I decide to do so later on. The larger ESCs also stay cooler than smaller ones granted they are both under the same load.
To use these ESCs I will need to solder on some 14 gauge ring connectors so they can be connected to the power bus terminals of the copter. I removed the stock bullet connectors on the speed controls and soldered on the ring connectors followed by some shrink wrap tubing (seen below left)....
Note: The Exceed RC Proton 30A ESC does not support a 400Hz refresh rate and will stall under load if subjected to this rate. Flight control units with ESC outputs at 400Hz and higher should not be used with these ESCs. This includes the DJI Naza-M flight controller...
