French Fried IBU2.

[jackalope]

Has anyone had any issue with the IBU2 being bad straight out of the box or am I the only one? My original set up is still perfect and I ordered a new set up for my Hobby Boss/Taigen Tiger build and found the sound to be messed up right away. Ian thought it may be the amp board because the heat sink would get too hot to touch, so I removed it and before I sent it back I hooked the speaker and volume knob up to the main board and was doing a bench test of the new board with the new TARR mark II smoker, and new 480 motors I also got from Ian when it suddenly shut off. Upon inspection I found the main fuse had blown and the chip in the middle of the board had a burn mark on the sticker and was VERY HOT. I let everything cool down disconnected everything from the main board and put in a new fuse which blew as soon as I turned the power on and once again the chip in the middle was VERY HOT. (Now I need to go buy a fuse for my King Tiger)

I'm sending everything back to Ian to get sorted out to see what happened but am curious to see what any of you think may have been the cause.

For the bench test I was running the 2cell lipo from my King Tiger which is known to be good, a brand new TARR mark II smoker which I previously tested and I know is good. The motors are 480 JS motors sent to me by Ian for use in this tank with the IBU2 and they both ran perfect when I broke them in in a bowl of water 3 days ago. The speaker and volume knob are also form Ian and came in the set. The motors are installed in 4.1 Taigen gearboxes with an external bearing mounted on the outside of the hull under the transmission covers from rctankde and are the same bearings I have in my KT. The tank did not have tracks on at the time only the drive sprockets and the IBU2 board was sitting on my kitchen counter with the smoker out the window as to not fill the house with smoke. The kitchen counter top is ceramic. I can't for the life of me figure what went wrong other then a bad board does anyone else have any ideas?

Hi The only thing I can think of is the motors 480 JS motors will blow an el-mod ,you can run permax 480 motors even 540 motors .

I got the motors from Tankbear and they're compatible with the IBU2. He said it sounds like it was a bad micro processor and it just fried itself.

[Tankbear]

Yes I think on this occasion the processor has failed but will know more when I receive back for checking over.

And the motors are JP480 not js480, so not to confuse others.

Oops, sorry Ian.

I had one do exactly this! Ian was great and it was sorted quickly

Tom so you're 1 of the 3 then, nice to know I'm in good company. I know Ian will take good care of me, it's not his selling a good product that gets you a good reputation it's the service after the sale that ensures repeat customers and good word of mouth to get new customers. Ian didn't come by his reputation litely he earned it and it's well deserved IMHO. But it's always good to hear from someone who went down the same road I'm going down, thanks Tom.

Hi Your spot with what you say about service, had a problem with one of my IBUs yesterday (it wouldn't steer) tried all sorts to fix it , sent a message to Ian ,Ian's reply had the fix it was a bad lead from the receiver problem solved. spent ages trying to sort it Ian sent reply in minutes (wish I had sent it earlier lol)

I have a 1/12 scale Centurion which has 2 540 motors running on 12 volts ,havnt had a problem yet . checked with Ian before a set it up ,he said it should take the motors . had to set the amps to 20 on the sd card. only had short runs so far still setting the suspension . May change the motors to 80t motors so have more torque less speed.
