EpicRC 2204 3200kv Full Results  [CLICK HERE]

  

This motor continues the high KV testing range I started last month. EpicRC was kind enough to send over this motor for testing along with the 2800kv variant.  These are OEM T-Motor 2204 motors, so the quality and build is excellent, and the design is quite recognizable with those of you who are familiar with the early MN series motors.  These motors have the 3mm shaft of the later revisions of that motor and the bearings are very smooth with absolutely no play in the shaft, and no notching.  Because these are true 2204 motors they are very light, so this combined with their high KV is a big point in their favor for smaller builds, like 180mm 4" racers.

Results

These motors did very well on the small props.  As with the 2800kv, I started out with 3" props, and the numbers on this motor were significantly higher thanks to the extra 400kv. I was pretty surpised by the output here.  Even the DYS 3x3 prop was putting out over 400g of thrust.  It's still not worth it on this weight of a motor, but pretty decent numbers, with the 3x3x3 breaking well into the 500g range.

4" props on this thing really blew me away at 4S.  The numbers here are insane for the size and weight of this motor.  The only down side is the amp draw matches the numbers.  Even the 3.5" prop cleared 700g of thrust though, and it only went up from there.  The HQProp 4x4.5BN prop was really too much for this motor. Amp draw started climbing fast and thrust dropped away, so we're hitting the torque wall there.  The HQ 4x4 and the 4x4x3 both did quite well though, with the 4x4x3 maxing out at 965g!  The motor did get quite warm on the heavier 4" props, but not drastically so, and is well within flyable ranges.  With the 4" props approaching 30A though you're going to need a killer battery!  With the numbers on the 4x4.5BN prop, I didn't even bother to try the 4x4.5x3.

I made the attempt to hit 5" props with this one but unfortunately the Diatone Ghost didn't make it.  The prop was so unbalanced at this high KV that it just shredded itself, tearing the entire motor off the stand and snapping the aluminum X motor mount I use in half.  Pretty nuts!  Before it shattered it looked like it was getting decent numbers, at not horirble amp draw, but I wouldn't recommend it given the experience. With these large props on this high of KV, and a light weight motor, balance becomes much more of an issue.
