1106 6000kv on the test stand


2s Test

383E 2 blade prop = 160+ grams of thrust , but the motor is cooking ( be that 6000kv )
333E 2 blade ( cut down 3835 ) = 157+ grams of thrust / 22,000+ rpm ( motor is cooking )
@ 20,000 rpm = 127 grams of thrust for 43.8 watts

3025 2 blade prop = 136+ grams of thrust @ 5A + / 25,000+ rpm
@ 20,000 rpm = 74 grams of thrust for 22.3 watts

65mm 2 blade prop ( pictured ) = 87 grams of thrust @ 3.2A+ / 33,000+ rpm
@ 20,000 rpm = 31 grams of thrust for 7.9 watts

This motor is supposedly 1-3s , and for me 6000kv is probably to high a KV for actual use .. ( Unless if you plan on running 3s and small props , in which case it might be ok ) But the high rpm ?
For actual use , maybe 3000kv to 4000kv would be a better choice . Especially if you want to run less current and more prop .

Even with such small motors , if you are running 2-3s , I just dont see the need for high KV .. ( Thats just me )

4v x KV ( 1s )

4x 3000kv = 12,000 rpm
4x 4000kv = 16,000 rpm
4x 5000kv = 20,000 rpm

8volt ( 2s )

8x 3000kv = 24,000 rpm
8x 4000kv = 32,000 rpm
8x 5000kv = 40,000 rpm
8x 6000kv = 48,000 rpm

I would say that for 2 to 3s , those high KV numbers are just silly ... ( For numerous reasons ) , one being the high current which tuns to heat . The other being that larger props are more efficient .
I did buy this motor for testing props ... But now , after seeing 160+ Grams of thrust ... I think I feel the need for a 1106 3000kv motor ...

UPDATE :

3s Testing ..

65mm Prop .
Wow , this motor does not like pulling more than say 35,000 rpm ..
As you approach 40,000 rpm the motor craps out ..
It did stay cool how ever , but peak RPM is reached around 50% throttle on 3s ..
Thrust is around 100 grams ..

I will try the 3025 next

3025 (3s)
33,600+ rpm / 9A+ / 225 grams of thrust / 108 Watts / Cooking !!!!!
20,000 rpm / 78 grams of thrust / 28.5 watt
