Monster Max 8S plans?

I have absolutely no desire to make a vehicle for me to ride on, but 5 or 6s 10,000 would be a good reason to put two packs on something. I have given plenty of controllers "the business" and thermaled them, when the battery and motor were fine. My MGM can take it with no problem, where the Monster overheats. If Castle were to make a 275+ continuous controller thats more affordable, everyone who has had to drop a couple of teeth to make their setup happy, will thank them.

If you're thermalling an MMM, you're doing something seriously wrong. I don't think there's a single other person on this board who's actually managed to thermal one yet; current-wise, they can handle *plenty* enough. And even if it could handle yet higher currents, this wouldn't have any effect on its ability to withstand high ripple voltages. It's an independent issue.

Besides...a true 275A controller like you're talking about would be simply too big to be practical in 1/8th scale. And if you used such a controller in larger models, the current throughput of the whole system due to the 6S limitation would render the whole system insanely inefficient and unreliable.

I agree. They're rated to 120A continuous but the components are good for 200ish. The only way to thermal one is if the fan breaks or if you are really pushing it too far. IMO 120-150 amps is all you need in an ESC as long as it's rated accurately, anything more than that and you should gear down or volt up.

People should treat what ever cont. current rating as the burst cont. meaning every time you grab full throttle your motor should ask for 120A or less. This is how things runs cool and also not grabbing full throttle and hard breaking helps a lot too. I think it's up to the manufacturers to make people aware of this so they don't get things confused. I would love to see a ESC, battery, wires, connectors and most important the copper traces found in the ESC handle 120A continuous. This is why the ones that claim 500A+ gets bitten in the you know what all the time. Does anyone have the KO BL esc? I would love to see what alien technology allows it to deliver 780A cont. and 3000A+ burst. Good thing Castle keeps it real A+++. Sorry for bringing other brands in here Castle (Patrick).

If I'm thermaling a Monster in my RC circle, I am doing something seriously right. The MGM doesn't have any problems with the setup, why does the Monster? No one else has thermaled one because you guys don't push the limits like we do. From speed-run cars, to ballistic 5th scale hill climbers, I have 5 RC's currently active, only one tenth scale car, and only one that hasn't broken 80mph. Weight is not our friend here. Startup current demands, braking demands, and drivetrain jolts during off-road high speed baja style races, tend to heat up controllers. When ten minute races with high paces mix, the lightest fastest machine usually takes it. Just because you don't have an application for this type setup, don't assume they aren't out there. I promise you that I can find a place for a bulletproof controller twice the size of the Monster on my chassis before I can find a place for another 5000mah pack. If my Monster could last a few more minutes in the enduros and make a few more passes in my Infernos at over 100mph before thermaling, I would only have those in my cars.

P.S. - I know about Patrick's extreme testing of the Monster, that you guys referred to, it was one of my cars that he was using.
