1105 - 5000kv on the test stand





This is the motor that is supposed to go on the little 450x wing .

Lets start with the 3025 prop ..

2s - 145 grams of thrust - 5.59A - 26,400 rpm - 45.5 watt
3s - 268 grams of thrust - 10A - 35,000+ rpm - 118 watt ( Getting hot )

3830(E) prop ... ( 383E )

2s - 191 grams of thrust - 8.21A - 22,000+ rpm - 62 watt

3330(E) prop ( cut down 383E )

2s - 170 grams of thrust - 7.61A - 22,800 rpm - 54.9 watt



Sorry guys , just look at how that current / power peaked from 2s to 3s with the 3025 prop ...
The larger pitchier prop would most likely peak even higher and just cook the motor .
The motor seemed to behave well with all the props tested ... Even ran solid to 35,000 rpm ..

I suppose if you were made of money , you could afford new motors as you cooked the ones you had racing ..
But seriously , 268 grams of thrust . From such a small motor ... !!!
You would probably kill the motor if you stayed on the hammer for any length of time , but I think this is the best motor tested so far for a 11 size .. ( From what I have ) ..

On 2s , with a well selected prop , I would dare say a sub 100 gram quad would scream fast enough for anyone (?) .
And powering a micro wing ? ( Yeah )
I just need to remove the 1103 from the 450x and give that a test ...

For testing props ? , I don't have a suitable motor .. I thought that 1106 might have done the job , but I was wrong .
Not that there are that many 1103 - 1106 props

Lets Compare !

0905 - 10,000kv
1103 - 7800kv
1104 - 4000kv
1105 - 5000kv
1106 - 6000kv

65mm Prop ( ? pitch ) 2s

0905 - 108g thust - 51W - 6.7A - 36,000 rpm
1103 - 106g thrust - 42.7W - 5.37A - 35,500 rpm

Cut down 3025 ( 2725 ) 2s

1103 - 122g thrust - 55.3W - 6.58A - 29,000 rpm

3025 prop 3s

1104 - 129g thrust - 36.5W - 3A - 25,000 rpm
1105 - 268g thrust - 118W - 10A - 35,000 rpm ( hot )
1106 - 225g thrust - 108W - 9A+ - 33.600 rpm ( cooking )

3025 prop 2s

1103 - 132g thrust- 60W - 7.5A - 25,000 rpm
1104 - 69g thrust - 13.9W - 1.69A - 19,100 rpm
1105 - 145g thrust - 45.5W - 5.59A - 26,400 rpm
1106 - 136g thrust - ????W - 5A - 25,000 rpm

3830E ( 383E ) 2s

1104 - 96g thrust - 21.6W - 2.5A - 15.300 rpm
1105 - 191g thrust - 62W - 8.21A - 22,000 rpm
1106 - 160g thrust - Motor Cooked !

3330E ( Cut down 383E ) 2s

1104 - 86g thrust - 19.2W - 2.44A - 16,500 rpm
1105 - 170g thrust - 54.9W - 7.61A - 22,800 rpm
1106 - 157g thrust - 22,000 rpm - Cooking ...

Interesting , very interesting .
Obviously that 1104 is seriously down on power .
And the 1105 is better than the 1106 ..

Hmmmmm .
