RE: Gruman Ag-Cat
Hi Outacontrol41 the moki 150 will fly your plane just fine I was using a 150 on my 35lb yak one thing about the 3 blade props they make the engine run very smooth but act like a brake when landing you have to land with a little power the moki 150 is rated to fly up to a 40lb plane so you would be fine with a 20lb plane.If you do get the moki 150 get bthe power pump 380 also and a turblater the pump is a fuel pump made just for the moki engine and the trubolater is uint that fits beteewn the carb and intake it helps with ilde and air/fuel ratio.
