new 9920s
 

I got my controllers back. I was noticing they look different.
I think the esc has bigger heatsink on them now.
I thought I would post them. Has any one else notice this.
The heat sinks are sliver now.
Does anyone know if they going to stay like this.

That's cool, it does need a little more cooling. Are the caps bigger? They look higher up, mine are horizontal to the circuit boards.

Hmm, maybe they are bigger since the heatsink is alot bigger. Looks good to me.

My post isn't really worth much...just posting cause CHC......was upset cause i didn't say anything....well nice pics..there & it looks updated....lol

I just got one of the 12020's from the holliday special. I got it and thought that the heat sink looked rather large compared to the 9920's I have had. I just though it was the 12020 was bigger than the 9920, but it could be they just upgraded the design for all of this eseries controller.

Wonder if there were any other updates???

Maybe Monster Mike can shed some light on this?????


EDIT: I also tought the old heatsinks were black, not silver like these new ones.

Take a pic of your 12020, i would like to see how it looks, since im thinking of getting one, or maybe the 9920. Dillema time! ;)

I like the bigger heatsink, but personally, I think the 12020 is just to large...I would choose the 9920...

too large for what?

Its like 1/8" thicker than the 9920.... Other than that its the same size.

Personally, I'm glad to see the heatsinks are getting bigger. However, I'd rather all ESCs come with a flat heatspreader so the user can decide which heatsink (and how large) they want to use. In a ST or buggy, you want small so it will fit. In a MT, there is more room so you can use a larger HS for cooler running.

Jhautz, I'm just saying, I think the 12020 is a little to tall...

Where would you put it that 1/8 taller would matter? Just curious.

Damn that things bulky! Hmm im really tempted to get the 12020 , as i like the extra re-assurance of it running cool. Ah heck, for 225 its a steal! :)

That 12020 is a really nice size now.

Cool! I wish that had put the bigger heatsink on the 36120 to. :(
I wonder about the new 7020s.

No were inparticular, but I just think its kinda large...

Good to see it has a larger heatsink.. Now it only needs to corporate with 4 poles, USB programmer, LVC and a build in UBEC.. :p

That'd be really nice!

I agree, the Micro's could benifit from this as well..........

Are these things worth anything any more?

Sheesh! Talk about raising this thread from the dead. :wink:

Unless things have changed, these ESCs don't support 4 pole motors, are expensive, have little programming capability, have no LVC, and can take ages for warranty work, I'd say there are better choices out there.

I still have one laying around.
I had to ask since I got an Antique. ;-)

These controller were how rcm got their start! The beginning of Schulze alternatives.

Up until about 2 moths ago I was running a 9920 with a feigo 15l in a nitro 4 tec conversion. Worked great. I also ran that setup in a 3wd light emax and it did well too. Both with some cheap 5s lipos. Never cogged or produced much heat. Lack of a lvc is not really a problem, if you are familiar with lipo. I used a castle bec with it. Paid 50 bucks for the 9920 brand new, and 35 for the motor. With bec and lipo I had less than 150 in it. Great system, but the new owner sent it swimming in a puddle.... Oh well.

I had a 18120 that was years old as well. Ran it with a BK 5407XL motor in a Emaxx, then Revo, then Maxx, then Revo again. Still ran like a champ. I sold it with the revo conversion a while back. They are fine controllers, but do lack LVC. For some reason, I could never program brakes in it tho...
