I don't think there are any others. I think the only other layout is the 3x3 setup that Xray used to use and the up the middle design of the new losi. The old XXX-S was right side, the RDX is right side, TC5 right side, and all the new Xrays are right side.
One I can think of now is the T5 ( I think that's the name ) by Kyosho. It's the shaft drive version. The T5 Stallion is the belt version of the same chassis, but I think it has cells on the right, if I remember correctly.
Edit: I just checked the Kyosho site and the Stallion does, indeed, have the batteries on the right.
