The 160 has a throttle on the left hand side, as well as in the middle, but the rpm and mixture control is only in the middle.
I normally use the LH throttle when doing aeros, but use the one in the middle when flying about normally, as it is located next to the other engine controls.
I've tried doing aeros from the RHS, but you need gorilla length arms to be able to comfortably keep your hand on the throttle while doing aeros.
