Exactly, that's what I had to do when I bought my FT TC4, before I started building it. I had to use my Dremel rotory tool to grind away enough chassis material in the right places so that the battery slots would accept both GP3700 & GP3300 cells(they are spaced right on the FT TC4 for the 3700's, but not for 3300's, so I had to work on that to get all to fit properly & of course to make sure the chassis won't ever cut into the cells' shrink wrap in a crash, smoothed everything out properly). I know that if you don't already have something like a Dremel it might seem a bit expensive just to use with your R/C stuff(I've seen prices for them anywhere from $35 to $120 depending on how powerful it is & how many features & bits come with it) but I guarantee it's a tool you'll never regret buying, they have uses for EVERYTHING, it's something every man should have in his toolbox....
