RCINPower GT2205 2300kv Full Results  [CLICK HERE]

 

RCINPower sent of their entire new line of GT series 2205 motors for testing.  This is the first of that series, the 2205 2300kv.  I'll be testing the 2550kv and 2700kv version of this motor as well.

Summary

Again this is the first RCINPower motor I've had on the bench, and I have to say I was extremely impressed.  The build quality on these is really top notch.  The design is nice both aestheically and in terms of build quality.  The motor is extremely smooth, and the tolerances are very tight.  The motor feels very solid as well, but only time will tell if it will hold up to the abuse we put these things though.  One interesting feature is the 4mm hollow shaft. It feels great and has the added benefit of a much stronger C-clip, and the fact that 4mm bearings are much better than 3mm.  One small issue with the design is that the cooling duct system lacks the exposed fins necessary to actually make it work, so it is essentially aesthetic and not really significantly functional in terms of cooling. Other than that this is a really beautiful motor.

Now on to the bench results!

Test Results

This motor really nailed the tests for a 2205 2300kv class motor.  The KV tested right on 2300kv, pretty much on the nose.  This gives it a slight advantage over the Emax motor in this class, given the Emax testing of closer to 2250kv.  That plays out in the test results, where the RCINPower GT outclassed the Emax by a small margin almost across the board.  Also the RCINPower uses a very unique magnet; thin, wide, and curved with tons of surface area facing the stators.  This seems to be extremely effective especially on the heavier props.  One other thing to note is that RCINPower claims an H or high temp N52 magnet, and in this case I am inclined to believe them.  I tested the KV of the motor before and after the test, and it was identical, which means there was no demagnetization at all.  This puts this motor well head of several others on the market claiming N52 right now in terms of long term use.  That being said, extreme high heat due to overpropping and then flying in already hot weather may still cause a slight KV rise over time.  I really don't think that is anything to worry about for the average pilot though.  Unless  you're flying 6x4.5s on HV batteries in Reno in August, you'll probably be fine :D  Overall I was very impressed with these motors.  This is a great offering from RCINPower.
