Im waiting for the day that castle releases a controller bassed on to-220 or to-247 sized mosfets :) then i can power my e bike reliably :)

HV ICE uses Infineon BSC031N06 (3.1 milliohm, 60V)
Mamba XL uses Infineon BSC019N04 (1.9 milliohm, 40V)

You'll be waiting a long time (forever) for TO-220 or TO-247 based controllers from Castle... They switch like crap -- too much package inductance.

There are much better MOSFET packages coming. TO-220 and TO-247 were designed in the 1970s, and just don't handle high dV/dT well.

Thanks for setting me strait on that one, my mentality was the bigger the better :)

Im going to shoot you a pm patrick.

Hi Patrick, what are the Specs for the FETs in the current Hydra line? the specs above point to a possible future Hydra Ice 200A HV ESC only 50% bigger and more expensive than the possible future Hydra Ice 200A LV ESC,
whereas the current Hydra 240HV Looks like its twice the size and close to twice the price of the current Hydra 240LV, have HV FET improvements narrowed the size weight and cost difference between HV and LV ESCs?
Paul.

Great reading!! I'm loving it!

Ps the xl almost seems to have abs braking.

Well, Arct1k and Pdelcast both just put in writing that this setup will handle bashing. I AM SOLD

esc brakes will make my conversion cheaper and simpler. You guys will see my e5b soon.

Until then look back at my $4000 gas 5b http://rc-monster.com/forum/showthre...ight=5b+thread

I've got cash in hand. Where do I buy a 5b kit? Also an extra omgwtfbbq esc?

I need 2 esc's a motor and a conversion kit. NOW! How? Where?

Thanks

Haha, I'm right there with you Harold. Once these are released I'm going to be having at least 2 sets coming to my door. Really can't wait.

Waiting as well... even bought a pair of 4s lipo's (ran in paralell now on a MMM, will go series when the XL finally shows).

I would use the esc brakes for the rear, and a set of mech brakes for the front. Use a radio like the m11 that has a dedicated throttle slave channel to mix the front brakes and you are good to go. Front wheels do 60+% of the braking anyways, and I always disliked the stability issues that rear only brakes cause during hard stops.

Good to hear the omgwtfbbq esc can handle 8s with braking, but I would have really like a 10s esc with brakes. I will hold out for the 12s model I think, as my selection of lower kv motors will suit it better.

[doo540]

You might be waiting for long time on that 12s esc.
Last time I called CC (last month) they said the 12 esc was on the back burner.
But they are trying to develope a 20s (yes 20s) esc for the airplane guys.
So we need to get people to boycott all airplane esc's from CC so that they will work on "car" market more. haha

[doo540]

btw who needs front brakes?
You cant win if you are on the brakes.
I will tell you this a 30lb 5T doesn't like to stop at all when using the stock rear brakes when moving 60 mph.

[DrKnow65]

doo540, I like the idea of 12S but I'm waiting on 8S with data logging and a real BEC circuit :-)

Without the price up for the combo yet it comes up as free in the cart, I wish :)

[doo540]

I have a real BEC its CC BEC PRO. Very nice unit and you can adjust the voltage output.
My Ice also has built in datalogger.........
Just missing reverse and electric brakes and car software, BUT I can run 12s and you cant. hahahaha
