Thanks for the compliments.

As for the batteries, I pretty much only use A123 cells in both my airplanes and cars. This was a battery pack I already had around, and so I designed everything else around it. I don't have a single lipo, but do also use standard Li-Ion 18650 cells for various things. I don't get hung up much on the voltage difference of A123 cells vs Lipos. In the airplane world, all you do is up the Kv of motor, and use a slightly bigger prop. Similar principles seem to apply with cars where weight is even less of an issue. Honestly, I think the voltage problem only really is an issue when it comes to racing, where there are specific tech requirements. At any rate, yes the mid mounted motor and forward batteries do make it difficult to wheelie, but easier to drive, (wheelies get old after a while).
