I am so done with cheap Controllers!

[egneg]

Howard, would you like to try a Scorpion Commander ESC. They are slick and program with a remote card. NIB 26 VOLT 180 AMP.
Engineered in Germany, made where every thing else comes from. $ 125 shipped to you. BG

These are great controllers ... I love them and wish they were easier to get here in the states.

Chuck, you can buy this one for $ 125 before I list it. I am going back to spec racing only. BG

Howard is running 10s. Does Scorpion mess with anything for 10s in the 200+amp range?

Is it the water cooled version with SBEC?

[ENCORE MAN]

yes, pictures available if you need them. BG

No. The Scorpion controllers appear to be air units converted to boat operation and 180 amp is the max I can find. BG

My SF240 survived being burnt by 6S2P in my 40" mono last summer. I cleaned it all off, added conformal heat transfer epoxy and it runs like a charm still. It is Ver.1 from Hobby King. One of the best esc's I've ever bought.
I just recently upgraded the firmware with help from Hifei. Nice lady was very helpful and when I'm ready I'll upgrade my SF200 V1 in my P-mono.

*The reason the batts lit up was because I kept running them with a bad cell(s) when I never should have ran them at all. The batts were HK Nano techs but, only 25-35C rating and they were a combination of 2 batches, one with 12G wire and the other with 10G wire.

I've got Dinogy for it now, they honk on bobo real nice.

I like the Turnigy 120 ESCs, but some of us have found a weak point with them too. In fact, Howard and I both bulged the caps in AZ by driving at less than full throttle for during heat racing due to rough water conditions. They are still nice ESCs, but require additional capacitors for all throttle range reliability.

[ray schrauwen]

Yes they have very weak caps but, I know this just by looking and I modify.

On the T120 I removed the original caps and added a pair of Rubycon 1000uF 35V 130* caps, the same as what Etti uses on their esc's. I also drilled out the heatsink tubes for more water flow. Still need to add extra conformal to it though.

The caps on the 240 are original just covered by epoxy. There is a before and after pic. Modify, modify. I added an extra pair of leads on the top of the esc so it is easy to plug in 2P setups. I also added leads that go to an Etti HV cap assembly not shown. There is a FC cooling plate added to the one side that had a .062" thick piece of aluminum.

Last picture is the 240 before mods.

Why do we have to modify them at all? They sell them as boat esc's.. Maybe the cheap ones but why modify a castle or a a schulze or YGE? They know how we use them.

[ray schrauwen]

No, I wouldn't modify any of those either. Just the Chinese ones because they buy caps (weak link) by the container load and possibly seconds. When I emailed and spoke to the "Cap King" and read his web site, I came to this speculative conclusion. Simply, most high end esc mfr's uses quality Japanese made low ESR caps while who knows were the caps come from on Turnigy esc's, etc... Swordfish seem to be o.k. ergo been through a good cooking and still going.

Schulze & YGE, I thought offered optional cap banks which is like modifying an esc. Schulze would most likely even match caps, that you'll never see from China... at least not yet.

Since were on CAPS. MR. PompBled from Sneed, Netherlands says using smaller caps will cool faster than bigger caps as long as you are within 20% of the total capacity of the original caps. I took a T-120 and added 2 caps, same size as original and runs cool.--- Hair off topic-- waterproofing with Corrocion-X by removing shrink and sparing X on; i know this will kill warranty but water can go where it wants to GO. Now has anyone done this to their escs? Used to be able to buy D-270 from OSE a few years ago like on Kunz brushed escs. Conformal works great and wonder if that would work also. Thanks and when you get time will be fine!

I have used CorrosionX for years on my receivers and ESCs - no problems. Conformal coatings are not as good a general protectant as many think - most are too viscous to get where they need to be. Example: the most vulnerable parts of Castle controllers are the plugs between the boards. A drop of water inside the plug and a short happens...poof! CorrosionX will get into the plugs and saturate them, giving at least some protection. Most conformal coatings are too thick to get to these hard-to-reach plugs, so protection is reduced. They worked great on Andy's ESC since they were simple with all components on one board.

Why do we have to modify them at all? They sell them as boat esc's....

Tell that to Schulze, for years their marine controllers were "splash proof"....

ESC failure can be caused by a number of things. May not nesecarily be heat, or fets.
Other circuits on the boards can blow like drive transistors from voltage spikes.

Just my 2c : )

[T.S.Davis]

Jay, they still say "splash proof". Even the big monsters with the case around them.
