I have now kosmik 200 kontronik and 4530 scorpion on my 700 v2. Flies like a dream. Plenty of power for my rookie style. I fly with 1600-2000 headspeed. The motor is near elev servo but it fits very nice. I have 800mm sab blades waiting but no stretch kit. Soon.

I have done same as jactor.

Can you explain why you think it needs a 160 ?
Do you have some flying record to see how much it drain ?
On the Box of the Motor it's written compatible with 120 and 160.

Thanks

For the gearing , I understand . no problem . But when i look to the tech specs, they are identical .
It's certainly safer to run a 160 but I really think the 120 is plenty .
That's why i'de really like to see how much it really drain from the CC log..

It really depends on how you fly... my castle 120 gets crazy hot with just the 800mx. If you are a mild pilot you'd probably get away with it.

But, the early history with the 850mx is that many people had shut downs with the 850 mx and the castle 120. doing speed passes.

the 120 is a tuff esc and its really light. the 160 is kind a brick. i'm doing my best to make the 120 work, I don't fly it back to back. it needs lots of time to cool off.fans help.. I have two 700Es one with the 120 and one with the 160. so I fly one, while the other is cooling.

the 160 is so heavy,if you mount it in the nose. it can create real issues with balancing the 700E

this is how I mount it...

Reviving an old thread here...

I am upgrading my ESC from the Align 130A to a CC 160HV.
Does anyone know the Align 850 motor bullet size to buy for my ESC?

The internal measurement of the female bullet on the Align speedie measures ~5.5mm; is that a standard size?

Thanks.
Ted

Thanks flipboy.

Using calipers I was getting between 5.3 and 5.5 but not knowing if the terminals were metric or imperial left some doubt.

Cheers.

For Align 850MX 490KV I think that 120A or 130A ESC should be fine but it is ok to mount cooling fan just in case. I am using Align 130A ESC from 700X Dominator combo and it is barely warm after flight, I manage to top it at 110A:
