Hey gus...I blew my Exceed Volcano 60A-OPTO when testing last night.

I'm running a HeadsUp 4260-06 motor; (2) 4S 2200 mah in parallel, and the prop I think is 13x5e apc.

Wattmeter read: 48.65 amps, 15.65V 767 watts.

I was taxiing my Big Bee around the street, then pulled into the driveway...blipped the trottle 25-35%, then the motor shuddered and stopped. It then spun he prop nut loose. I checked the motor...it was cool and moved freely. Started to tighten the nut again...then I hear a smouldering sound...then see smoke! I was able to yank the esc out w/o damage to the plane.

I'm awaiting hobbypartz' response.

I don't think I did anything wrong.

Here is my build thread with pictures.

Hobbypartz sells the Monster Power line of larger motors. They are a great price, but are 40-60% heavier than the expensive equivalents. And the Monster Power motors don't put our the kvs of more expensive motors.
The 10 and 15 run fine on 3S LiPos. The 25 and 32 need at least 4S voltage.

I like the Turnigy 42-30 size on 3S. The 35-48 is sluggish on 3S. The larger Turnigys seem to need higher (4S+) voltage to reach their "aerobic" zone. The larger Turnigy motors seem to have lower kvs than expensive equivalents.

I like the quiet power of the Monster Power 46 and 60, but they seem to need 5S or higher voltage.

I have a Monster Power 32 with 4S in a 50" Diamante (4.5lb FUW). It has sport power, but not really aerobatic power with 4S. I haven't been really pleased with the 500-600 watt motors on 4S. I'm still looking for a high kv motor of this size that will loaf on 3S, and fly powerfully on 4S. I am tryin the Helium 500 watt 1500kv motor with 3S LiPos. I burned one up with 4S (it didn't come with documentation...).

Good luck.

I ended up putting the Turnigy SK 35-48 motor in this Stick 25e -- running a 4s 4000, that thing is a power house! I love it -- even with the added weight of the floats, it hauls at even half throttle. Way more power than I need, but....

I thought you would be happy. I set up the same plane with that same power system for one of the other club members at my field, and he's pretty satisfied with his too.
The output of the SK 35-48 is impressive for it's size.
I actually burned one up for the first time this past Saturday, was running it pretty hard on 5S spinning an 11X7E APC prop in my E-flite T34 Mentor, and it finally cooked. I wanted to see just how hard I could push it, and it surprised me at how long it lasted. I had probably 2 dozen flights on it with that setup.
On 4S, it should last a long time as long as you keep the Amperage in check.

Video???
