Gary Mueller's center line kevlar tank was originally plugged by one of our club members, Paul Jacques in Oshkosh, WI, who, as a pro builder, has plugged conformal tanks for several of his creations. You can see his tank designs on Gary's website.

The KC centerline tank was initially fitted to our buddy Brian French's KC cuz he like smoke thruout most of the flight. It can be purchased in the French size, which actually holds 90 oz and just fits, front to back and side to side.

Brian at the time flew it with a P-120. His style was much like today's EDF flight profile with lots of hot low passes with pull to vertical maneuvers, followed by going to idle on the downwind, turning altitude into speed for the next pass. That was he could fly up to 12 minutes on the stock tanks into a UAT.

Only caution was that if he flamed out occasionally early in the flight, gotta be ready cuz it is coming down......most guys ended up using the 1/2 size version of 45 oz for smoke or more primary gas.

In my old KC, I stuffed a 24 0z Dubro rectangular tank in the midline....fits perfectly and 8 0z more than BV's stock 16 oz centerline tank. For a while I had a P-180 on it and it was good for 6.5 minutes the way I fly. Now I am back to a Wren 160 and am good for 8 minutes full tilt most of the time with about 30 oz left.
