T-Motor F60 2207 2450kv Full Results  [CLICK HERE]

  

This is the insane big brother of the F60 2200kv.  This is probably one of the craziest motors I've yet tested on the stand!  I never thought I'd see numbers this high, both in thrust and amp draw!

As with the 2200kv version, the build quality on these is awesome.  Windings are great, tolerances are tight, curved magnets look fantastic and the motor is extremely smooth.  As with the 2200kv, this motor weighs in at 35g, making the weight the only real downside in my opinion.  This prototype I received for testing has the laser etched bell, and I MUCH prefer it to the stickers on the other F40s.  I hope T-Motor decides to go with the etching for the final production version.  I have to say I wasn't really prepared for the insanity this motor unleashed on my bench.

I really struggled classifying this motor. It's not really very high KV. Typically I classify anything as high KV if it is over 2500kv, but looks like I'll have to make some adjustments for the larger stators. I also didn't bother with the 4" props, as there is really no application for a 35g 2207 motor on 4" props. The torque this motor is capable of production blew me away.  I still need to run the second order metrics on the motor to quantify response times, but it just never ran out of torque.  Even the heavier props were being driven hard.  If you told me I would see 1700g of thrust from a miniquad class motor I would have laughed, but on a 6x4 KingKong this sustained over 1700g through the whole 3 second burst.  Unfortunately amp draw also reflected that, hiting over 38A sustained.  Even with unloading in the air, that will put some serious hurting on any battery currentlyon the market, so that probably makes the KK 6x4 and unreasonable prop, but the fact that it can push it says a lot. Even the ligher weight 5" props are hitting some high numbers.  Both the 5x4.5x3 HBN prop and the 5x4x4 cleared 1450g at a "fairly" manageable 34A.  Unloaded in the air that should be survivable on a good battery.  Even the 5x4x3 broke 1400g at just shy of 32A.  Like I said some big numbers!  This motor is headed into terriotry that will be interesting to watch.  The combination of torque and pitch speed will create some very interesting flight dynamics, and the way it unloads in the air will likely be a bit different from the higher KV but close to equivalent pitch speed counterparts (The Emax RS2205 2600kv is only 25g shy of the 5x4x3 numbers, and the ZMX 2206 2600kv matches them). As I said my only wish is that it didn't come at quite the weight and amp cost.
