RE: Gruman Ag-Cat
Outacontrol41 how you doing.My agcat is 104in wing and the longer fuesslarge (B) model I think is what Duane said it was.The smallest plane I ran a moki 150 on was a 33% yak 54 that wing was 95in was just wright for the 150 just beef up the engine boxs and I added carbon fiber landing gear had to add 2lbs tail wieght to balnce.89in wing in a byplane should be ok for the 150 that plane has a lot of drag a good prop for that set up would be a 28x12 with a power fuel pump 380.That is a special fuel pump for the moki engine suggest to install them with ever engine.Call Gotz at Vogelsang 1-919-533-6275 and ask about the pump and a trobolater.well worth the extra price they will run like the one;s you see on you-tube.Is your plane one of Duane kits with glass fuesslage.
Take care wr450
