Buy a Loki 8000n case, find a CTI Pro75 adapter set , a.k.a. "hubcap". Get some Pro75 spacers, snap rings. You can fly a 4g, 5g, or 6g AT or CTI reload. Even if you buy a Loki nozzle and fwd closure , you can fly Loki reloads, too. It will all work in an AMW or Kosdon 7600n case. All that hardware is cheaper than an AT motor set.
