Differences between high end ESC's and cheap ones for Lehner motors?

[StevenBryant]

Ok I will have to haggle with the seller and see what price I can get them for, what price would be sensible for these units?

In general, yes I like the newer and older Schulze's quite a bit. Look at the two on the left, these is the extreme case of extra caps. This was specifically for the 2280 and 30 series Lehners.

That’s a nice collection 161’s, unfortunately the shulzes I was going to buy have been sold to someone else now. So my options are the MGM 400, what about the new Swordfish 300 X or the Atos 300, do you think these controllers are good enough quality to drive a 2280? I’m considering the MGM esc but the size is a concern.

How come you don't see anyone adding fets to Schulzes or any other ? Besides gunner that is. I would have thought it to be a straight forward process...

[RaceMechaniX]

I have no experience with the newer X series from SF. And based on what I have seen from the Atos 300, it will not live up to its nameplate rating.
The best option for the 2280 is the 40063, but be prepared to prop down as it will likely start to current limit at some point.

Adding FET's is not like adding Caps. Gunnar, Arne and Joerg made special boards and used a Schulze control board.

A few spares in my box

but nothing compared to this hoarder.

How many amps are you able to pull with a Castle ICE (with enough water cooling) ?

I've spoke with the MGM guys at one point and they mentioned that they would be able to upload a custom firmware that would turn off all limits.

Is this the specific one you are talking about?

I’ve run the mamba xl2 converted to water cooling. It’s the exact same board as the ice 250 but different firmware. It’s extremely durable except for moisture. I now epoxy coat all of mine. I like the “elegance” of the mgm because they are very nice controllers but I did blow one up paired with a 2260 in a mono. I don’t recommend doing that, Keith Bradley even told me that the lehners didn’t seem to like a v hull. I’m sure others may say differently but that’s been mine and his experience. He mentioned something about Joel thinking the same thing too, I didn’t hear that from Joel personally. I do have a mgm and a neu 1521 in my newest mono and I’m not so sure I really want to run it. I thought about trading the mgm for a newer sf300. Just my .02

Wow that’s some collection of controllers, what size is the MGM 400? It looks huge and will definitely not fit in my rigger lol

kfxguy, you are planning to run the 2260 on 6s? Maybe go up in voltage ... 8s or 10s, etc.

Mmm, well then there goes my suggestion of a Flier 400. There are a couple versions of it tho, one WP and the other not so much but then smaller.

You know, I always learn something from Tyler’s posts. This time an improvement on Castle conversions.

srislash, you put your HPR on the water yet? hows is it ?

Not yet but she should be complete in a few days Dmitry. Build thread is on here.

Tyler, Any differences going with ICE 200 over the Edge 200 ?

Figured a newer revision would be updated with more modern switches and all that. Or did they stick current limitations on the Edge ...

[RaceMechaniX]

I have not looked at the Edge in any detail so I could not say. I believe the biggest change was on the control board and in software. I don't believe the power stage changed at all.

Tyler, how much extra caps would you recommend on the ICE 200 ? Around 5k would be fine?

BTW - where can I buy some super high strand 10 and 14g copper wire? I remember OSE used to have some limited stock of the German wire before which was really good stuff, now I'm trying to find more of something similar. I believe it was like 500 or 1000 strand. Is the stuff from Castle just as good?

[dmitry100]

I think i found some good ones... TQ wire. Though a little silly no one ever has it in red.
