Well, the one I was actually looking at (just to see it, not to buy) was this one. One neat feature is the reversible shaft so I can decide which way I want to mount it. It certainly looked beefy enough, but again, I just don't know enough about them.

I want to set it up like a real RWD car; motor centered up front, driveshaft to the rear diff. Probably using a custom ladder frame design with 2s2p on each side (to keep CG low) for a total of 4s2p. Maybe use two A123 M1 3s2p packs instead. This type of design would also leave me PLENTY of room to lay out all the electronics on top for optimal cooling. Then, get something like a 1/8-1/10 scale old-style dodge charger body with proline on-road street tires or slicks mounted on mag-style rims. I was thinking of using Revo shocks since they are short and offer quite a range of spring rates. I'll probably make a wheelie bar similar to those seen on real dragsters. I definitely want at least 60mph. Something to turn heads. I'm thinking of incorporating the ability to add weight (steel blocks or similar) in the rear to keep wheel spin to a minimum.

A lot of this is on scratch paper right now, but keeps getting pushed aside because I didn't want to deal with a way to reduce ~35-40krpm down enough to use direct drive. For a while, I was looking at using a planetary inline gearbox like this or this, but really don't want to deal with ANY kind of transmission. It's just one more thing to go wrong, and they aren't cheap!

One of my LHS places has a bunch of flight guys, maybe one of them knows more about the out-runners. Actually, it would be nice to talk to someone who has used BOTH inrunners and outrunners and knows how they compare.
