Burnt my 2.4 module for helios ex-10

hello, despite my efforts to not reverse the voltage installing lipo on my helios ex-10, i did it anyway! I have fixed the battery problem but i burnt a component on my 2.4 mini-z module. If anyone has repaired one before please let me know where you found the replacement component. The part that blows is a 7mm long black rectangle(soldered on the board) that has a white bar at one end and the number "47" and "20V" on it...thanks

Pretty sure that's what you're describing.

I did this exact thing to mine, managed to fix it no problem. I'll see if I can find the info. I have a thread here somewhere.

I had to send two of mine to KO America to be fixed. They told me to stop the charge on the lipo pack at 12 volts. if it goes much higher then 12 volts it will blow some of the components inside the radio or in the module.

Funny (Not Really ), we had this exact thing happen to one of our racers Modules last night, plugged in the lipo wrong. I dug though my parts and was able to get his module fixed up and working.
