Blown Etti esc

[Flying Scotsman]

I have been trashed for saying this before but buy an amp, voltage and temperature monitoring device. This device is in inexpensive and will save you money in the long term. Also start with a small prop and cells at least 20% below the max for the ESC and motor and as Fluid stated do not believe everything you read or see on the internet, as some silly setups will result in a destroyed boat. There are experienced racers...not me...who can run hot setups, as they run the boat dry and know the limitations of certain equipment.

EagleTree is on its way from OE, at last... together with 440 prop. Now we will take it slow. Its time to learn all of this.

[Jeff Wohlt]

You are safe with that set up...should be able to handle that with a 80 amps ESC actually but I would stay 100 or above.

Heck, the SV set up is only rated for 45 amps and very few problems with them the UL1 ESC is pretty dencent too at 60 amps.

I just came home from a short run with my Lizard Extreme. Normally I use a 10XL, but this time I tried out a 7XL and the capasitor(s) on my etti 150 explode and the hatch got blown off and sank. My question: what do I do with the esc? can I just test if it works without the capasitors? And how do I fix it? I see OE have the capasitor bank..? Blease help me out. I used a 442 prop when it happend and the gps showed 72 km/h.

Lol i had the same thing happen with my Lizard Xtreme blew the caps and lost my hatch i sent the esc back to Etti and Dee replaced it free of charge he suggested to run the cap board it is now running strong and hard MHZ boats rock,here is a video from a couple of days ago

Wow, thats awesome. What setup do you have? Then I must try to send it to Dee and see if he can fix the esc. Do you have some contact information? thanks

Adrian this is one of the best monos I 've seen running. Stable and fast!

I have blown 2 Ettis 150 2-7s, one with extra caps one without. Probably due to a little extra wire. Sent back one (other is in trash) and waiting to see. Keep your battery wires as short as possible.

Hi Disar thanks that's a big compliment I always get a buzz running this boat,no trim tabs or turn fins and it's so stable with no bad habits

One more ESC

Now I am very confused I got this new Turnigy Marine 180A, and once I started it very easily the esc got smoked. This was with 11XL and 4000mA 4S 25/45C. What is wrong or what do I do wrong?

[Flying Scotsman]

It sounds like you have a battery to ESC to motor connection problem, or a defective battery, as I note this is the same battery you had before. What prop?

Douggie

Its the same battery as last time. It was a 442 prop, but I didn`t drive. I just tested at home, and when I barely pushed the throtle it got a lot of smoke.

[Flying Scotsman]

I think the battery is shorting under load.

I think the battery is shorting under load.

Douggie

Is that possible, that its just shortening under load? and not all the time... Should I try to buy new battery and esc and just try again? The motor cant be the problem?

[mike martin]

can you spin the motor by hand ?
