This kit was designed for EDF, no fuel tank is available. I thought about making one, I used to build foam core, fiberglass/carbon vacuum bagged kite boards, I know the process, just don't have the time. So, I bought every size of dubro fuel tank from 10-20 oz and will mix and match to figure out 26-30oz of fuel. I have to have at least 5 min flight times. The fuel burn on the KT45 is 5oz a minute. I am always somewhat skeptical of that figure, so will figure out on my own. 2oz header tank. Dreamworks has a 30oz "header" tank made out of kevlar, its $130, I got 5 of the dubro tanks for $25. I can see this being an entry level kit for some modelers and will keep that in mind with my equipment choices.

The narrowest width between the inlets is 2.5 inches, but lots of vertical height, so I will stack two on top of each other.
