escs catching fire

[viper1]

Did anyone mention a possibly submerged prop?
For experienced boaters surface drive is second nature, but for a beginner this might be a new concept.

Lots of good advice here, but I've been running that same motor on 6s almost daily for months last year on a 42mm prop with no issues.
edit: just noticed OP uses 3-blade, I stand corrected. Not sure about load comparison between 2- and3 blade, but 37mm still sounds small to me?

My vote goes to the throttle (mis)management in combination with set-up.

Like Fluid said, run on 4s first, get it all running properly, learn.. than upgrade.

Im thinking its your driving style. Consider smaller props so you can drive with the throttle wide open. Less than wide open causes the esc to over heat.

Buy a better motor. You can definitely run 6s on a 1900kv motor with a small prop, but apparently not that one.
Cheap motors can get wildly inefficient at high RPM.

In post #6 you said your motor was twitching and you gave it throttle and
It sounds like a bad solder joint on the motor wires or a bad winding in the can.

Yes you can on that one, and it is surprisingly efficient for a 'cheapie'. Unless your particular motor is damaged or otherwise not in the condition it is supposed to be.
Takes easily a X445 on 6s.

These may be SAW set ups & not recomended for beginners but this motor has been run on 6s successfully by a few people. In much larger boats ie Apparition cats & Genesis cats @ mid 60s, he must have something seriously wrong in the boat set up to be doing this in a small 580mm hydro on a small 37mm prop.

The evidence presented does not support your claim. 1900kv on 6s is not crazy RPM, especially for a hydro running a small prop.
You may have ran a similar branded motor without failure, but such is not the case here. Buying the cheapest motors will result in the widest range of quality, meaning that "the condition it's supposed to be" is not easily defined.

I would buy another motor before another esc. I run 40000 Rpm in one of my boats. It's not all that crazy what you're doing. Sounds like the motor may be defective

The evidence is literally all around you, I'm not taking the bait this time

I agree with Keith, change the motor. 1900kv with that prop is a bit high I would change out to a 1600kv leopard or castle motor. The seaking 180 is a robust esc when used correctly, guys hes burning up a turnigy 200a 12s esc with this little boat, red flag. Make sure there is sufficient gap between the drive dog and end of the strut bushing also as you can get some huge spikes if anything binds.

A properly setup fe boat can provide a lot of hassle free fun you've spent a lot of money on escs I think its time to change out the motor as the esc is not your problem.

I like 1500kv for 6S... unless it is a SAW config, it is a very good idea to keep RPMs under 40K. I personally target 25-35K RPM for a reliable boat.

You're missing the point. It's not the RPM, it's the quality control on the less expensive motors. Because your particular $50 motor works on 6s does not mean the OP's will.

[properchopper]

batteries r not swollen they just got burnt from 1 of the many esc fires. prop is 1.4 37mm 3blade.ive had hot setups before but this setup runs cool as.connectors r xt60s and 3.5mm bullets.just seems odd how 1 of the escs catch fire on my bench :S just giving it a bench test lol.but yea ima put another 200A in it and when it catches fire ima let it burn the whole boat I will make sure I film it

Anyone think these connectors might have something to do with the situation, resistance-wise ?

[lenny]

The first thing you need is,
5.5 bullets all the way.
And than to read about setup that work,
Before you try to mod things on your own.

[1truckerdan]

I thought about the 3.5mm connectors also, but the twitching issue when throttle is given says to me to look for a break in the flow (and feedback)of the esc to the motor.
