I now have 13 flights using the RC Timer 40A ESC in one of my planes. I decided to match it with an RC Timer 2212/6 2200 Kv motor first and put several flights on it with this setup before moving up to one of the "medium" 2212/6 2700 Kv motors which pull quite a few more amps.
On start up, this ESC is a bit different than the Turnigy Plush that I am used to in that it takes a few seconds longer to "initialize" if you will. When I connect the battery, I get the three beeps telling me that it recognizes the 3 cell battery, but then there is a 3 second pause before I get another beep telling me that the system is ready to go. With the Turnigy Plush ESCs, this last beep takes only about 1 second or less after the three cell recognition beeps. I certainly don't think this is anything to be worried about, it is just different and something to be aware of if you decide to try this ESC.
This ESC/motor combo works very well together, throttle response is very smooth and linear, after setting the throttle points as mentioned in my first post, the throttle response was continuous throughout the throttle range. In other words, I didn't get to 80% throttle and then not have any change as I put it to 100% throttle, power and speed continued to increase right to the end of the throttle range.
I am using 6 RC Timer nylon gear servos on this plane, so I wanted to push the built in BEC (3A/5V) to see if it could handle all six servos operating at once and still deliver enough power to have control of all 6 servos. I was not able to do any high alpha because of the wind conditions which is normally a good test since I would have all six servos deflecting control surfaces at once, elevons, spoilerons and rudders. So instead, I took it up high and just kind of slammed the sticks around with elevon, aileron and rudder input all working at the same time. Everything worked just fine. I also did several coordinated turns feeding rudder in with the elevons and ailerons and everything worked well. So for this setup, I am happy that the BEC can deliver the power that my servos need.
After landing, I checked with my trusty finger to see what sort of heat build up there was, the ESC was just barely warm, nothing that would worry me. As I try it with other higher amp draw motors I am sure it will be a bit warmer post flight, but with this setup it is fine.
So my overall impression with this "mild" setup is that this ESC can deliver everything I need without problem. I will continue to fly it with this combination for a few more flight sessions, then pair it with one of my "medium" motors and push it's limits a little harder to see how it performs.
