Default Choosing the right ESC for a brushless HPI Baja SS 1:5

I have been running large scale petrol cars for a few years now but now I want to experiment a little with brushless cars. I already have a Hyper9 E, a XB 808E and an ERBE. All great cars but I want a true large scale brushless car too.

Now here is the setup as I see it:
Car: HPI Baja SS (got three to choose from)
BEC: CC BEC PRO (got it)
Motor: Neu 2215 750KV & 480KV (Ordered)
Kit: RC-Monster (hoping Mike will soon get it done:love
Batteries: Will test 8S, 10S and 12S setup (Got the batteries except for 10S)
ESC: This is where you guys can help me out!

Looking at CC's tech documentation it shows that surge watts for the 2215 is 5000 Watts. My calculation for 8, 10 and 12S setup's look like this:

5000 = 44,4 x A => A = 113 Amps(12S config)

5000 = 37,0 x A => A= 135 Amps (10S config)

5000 = 29,6 x A => A = 169 Amps (8S config)

Judging from those number I need an ESC that can handle up to 12S and 169 Amps. I have read quite a bit about the possible ESC's that are out there. I may of course have missed a few but nevertheless I have had my eyes on the ones listed below:

Castle Phoenix HV-140 Brushless Motor Control ($360)
http://www.castlecreations.com/produ...hv_series.html

Castle Hydra HV-240 ($540)
http://www.castlecreations.com/produ...a_hv_line.html

Hobbywing Platinum-120A-HV (price not shown)

http://www.hobbywing.com/ENGLISH/Art...?ArticleID=440

Turnigy Monster-2000 200A 4-12S Brushless ESC ($190)
http://www.hobbyking.com/hobbyking/s...dProduct=10332

TMM 10063-3 Car / Boat Z-SERIES (€326)
http://mgm-compro.com/index.php?tid=...-boat-z-series

And then there are the Schulze ESC's too.

Bottom line for me now is that I need some input from this forum. I want to hear if you have any experience with any of these ESC's using a somewhat similar setup as I want to use. I urge you to post the setup you used and how it performed. If you know of relevant topics that debate the same then please link to those or summarize the major points here.

Please keep it to the topic and help me out on this one.

Thanks!

http://www.rc-monster.com/forum/ <- might be a better place to ask.

Also Lutach from that forum sells a 10s lipo capable esc I think.

I have posted the same question there but have had no replies. Please also note in my requirements that the ESC must be able to handle up to 12S and 169A.

the turnigy monster would be the best bang for the buck- watch your temps though, when youre slogging it off road any power not directly converted to motion is wasted as heat. 5000 watts of heat. i suggest running the clutch or installing some type of slipper unit.

A clutch would be a VERY bad idea on a big electric conversion like this, Even with a 8mm shaft it can easily be snapped, I mean imagine that motor spinning and then just engaging full force with all that tourqe...Ive seen it happen not a good idea to run a clutch.

Instead of a clutch/no clutch discussion I'd prefer if we could stay on topic Any feedback on the ESC's would be great!

Alright, Well the best I would suggest would be the Hydra 240. Personally thats what I would get. I really wouldn't waste your time with the chinease ones and the schultz.. The schultz are just big time bombs that like to smoke. The TMM wouldn't be that bad of a choice either but the Hydra would be the hot ticket.

I have been leaning towards the Hydra 240 but I am worried that cooling may be an issue. I could of course add a heatsink or something.

It really shouldn't be that much of a problem a few people run and get good temps with no fans and some use fans to bring it down further. Depends on how you run.

You would get more response in the large scale section on this forum. There are other guys who have done the electric conversion.

you talked about thinking you may have cooing issues- with water cooling you could get as cool as you needed.

you may not have any heat issues at all with that esc on the lower kv motor on 12s
if so use a small fan to help

a local guy has his king 5b set up with the jazz 63, its rated for 120 continuos and 200 surge, he runs the cable brakes of course and 14 s with a 2280 lehner which is smaller around but longer than a 22 series neu.

The aircraft ESCs don't have any kind of reverse and the braking is based on throttle level, rather crude. You want to stay away from those if possible.

the bigger lehner motors are only rated to 50,000 rpm, at $440 each people tend to push them less

Yeah I never say the point of having mechanical brakes on other brushless stuff but these are big heavy cars, you almost need the cable brake setup for hot gas motors let alone the brushless beasts, it also helps keep your temps way down not brakeing with the motor.

why would you wanna convert a 1/5 buggy to electric. its going to take alot of motor and battery to keep with thing moving.

No not realy, it can be done with a decent cost.
