I am looking to buy a 200A ESC for the Logo700 I have coming. (I will be running the XNova motor if that makes a difference)

I have used YGE only up until now on all my other Logos.

The options on the table are:
- Hobbywing Platinum Pro 200 V4
- YGE 200HV (with heatsink)
- Cool Kosmik 200HV

I would likely use the VBar governor on the HW and YGE. I am told I can't use the Vbar gov on the Kosmik.

Why would I pay double for the Kosmik compared to the price of the other two??? What does it do better? (besides being the only one with a BEC)

What would be your choice and why?

Thanks for any opinions and info you may have,

Kosmik would be my choice for these reasons in no particular order:

1) Internal governor works great.
2) BEC is excellent.
3) Reliability.
4) Ease of setup.
5) I like the mounting tabs for connection of battery/motor wires.
6) Convenience for telemetry output for use with TelMe or jLog and not requiring an in-line fuel gauge between battery and BEC.
7) An equivalent BEC for an ESC that doesn't have an internal BEC will run $100-200. Internal BEC in Kosmik makes wiring easier than using an external BEC.
8) Service and support.

Why 200A?

I think you can use the vbar govs on the kosmick. Why not 200 amps if that is what he wants?

Don't say that on the Kontronik channel! They get pretty exciting over there if you suggest doing that. Apparently, it even voids your warranty.

Richard, I can warm up a 160A ESC on my Logo690 with 160A+ peaks in the current. The Logo700 is slightly larger and I prefer to run my electronics well within the "envelope".
Besides, I have now added Tribunus 200A to my list of contenders and they will only have a 120A and 200A available by xmas.

Ok I understand.

Just FYI the current rating on an ESC is the continuous current limit and they can usually handle double that in spikes and maybe 50% more for 10 or so second bursts. If you were to absolutely wring out a 700 in a crazy 3D flight you would only average around 70A.

Just trying to save you some cash is all.
