Engine Bypass and Engine:
The supplied by-pass duct in my kit is huge, it could easily house a 180 class engine. To get it to fit in, it needed to be modified which is engineering speak for butchered. A slot needed to be cut at the 6 o'clock position to clear the forward engine former. With the duct sitting in position I applied heat to the upper area of the slot just cut and remolded the sides of the duct to clear the former. PITA really, but as the nain wheel wells are positioned at the intake area, the by-pass duct is necessary.The tail pipe bellmouth is silicon mounted in the rear of the by-pass duct then the very rear of the by-pass is cut down to expose the bellmouth spigot. The tail pipe align's to this and is retained by the straps secured to the bypass duct.
The engine I chose to use is a Kingtech 140F which fits perfectly and aligns nicely centered to the tail pipe. The ECU, Valves and Ball Valve are mounted to a plate on top of the main tank. It could have gone further forward under the canopy but at this stage I was starting to get a little concerned of nose weight, anyway it looks ok where it is and is practical.
