I think I even tried some ib 3800 16 cell packs. I tried a 7xl feigao as well. Had to change motor mount to get it on there to. I am open to suggestions. Please tell me something to try.

An oscilloscope is a box with some type of monitor on it which enables you to actually see the waveforms of AC signals (and DC too, but that can be done with any multimeter). There are a (sometimes overwhelming) number of controls allowing you to select a setting which will allow you to view a whole range of voltages and frequencies from very low (10Hz) to very high (GHz, although the higher the frequency it can view, the more expensive it is). It is a VERY useful tool for anyone doing anything with electronics - actually, it's indespensible.
Here is a page which explains better than I can:

You might be able to do the coil thing I explained in my previous post with a multimeter, but it will have to be able to measure a range of AC frequencies - most of them only measure AC close to 60Hz accurately.
Any electronic repair shops and maybe technical schools/colleges will have one. If your issue is not resolved, maybe they will let you bring in your R/C to perform the test I mentioned for a small fee, if any. No matter what, it will be cheaper than blindly buying possible solutions until something works (unless you have that much disposable income). If I had a BL setup, I'd perform the test for you and report my findings to give you a starting point. Actually, since you are having this issue, I might do the test once I get my BL stuff just for the heck of it. :)
