Well, Installed new aluminum main shaft (which will strip if you tighten screws). Rackon swatch and no more wobble but a bit of TBE. One pack to test.

Now the problem, plug a new pack in a the blades start spinning and smoke comes out of the 5in1 board by the left hand side servo. my guess is the board is toast. Any ideas? Has this happened to anyone else.

problem will never be fixed......myself

Ok so I had this great idea of wanting to know the amp draw a 120 sr has? So I pull out my in line watt meter and puff goes the dragon. I should have checked the polarity, yup the 5in1 does not like reverse polarity.

Well at least I know it was me and not the boards fault. A fifty dollar lesson learned.

Did that to a CX3 once...yep, it wasn't pretty.....but it sure was final

(and it taught me to mark my battery connectors)

Once you let the smoke out, its pretty much over.

However the solution is equally simple - buy a new board and get back in the air!
