what is the difference in the mr-015s and the i series?

The 'i' series cars have no brake function

It's more personal preference.

The MR-015 probably has the same board as the MR-02, whereas the I-series PCB is slightly different - the FETs are on top of the board instead of on the bottom. At least it is with my MR-02i, so I'm going on a bit of an assumption that the MR-015i is the same.

This means stacking the FETs on this board may be difficult (impossible?), since they would be pushing on the top chassis cover instead of hanging down into the chassis' open space above the on/off switch.

My car also came with 3004 FETs, not 3010's, though being on top and not near that large square box made 'em easy to swap off. I think it likely that all the i-series boards come with 3004's. Check out the attachments, as mine fried so I had the chance to swap 'em out and put 3010's on.

But ya, functionally, the brakes are the main difference, and my kids like this car much better than my 'normal' MR-02 since the reverse is so much easier for them to use. I prefer having the brake...

Looking at those attachments again, the MR-02i board also doesn't appear to have FETs to manage the steering - at least not the normal 3004 FETs.
