| Hi  I really liked the hurrican so I bought one I personally don’t like 8.7 ratio for my hyper so that’s why I changed it to 8.5 ratio there is a Nova Rossi C50H1 that would possibly suit 8.7 better without the engine screaming, its max torque is 2.2hp@ 18000 rpm you can read about it on engines and mufflers Tmblewd has bought one to try I also didn’t get on with the canopy so I fitted a raptor canopy instead so you can make your own mind up if you like it or not I flew the model but it was blowing a gale so I can't say much other than I got It down in one piece after flipping It and rolling it and the JR8900 is ace and worked great with a CSM 560 version 3 it was hard to part with my raptor but its done now I intend to go electric with this model so I have purchased the conversion kit, the hurrican will do a hurricane soon.cheers hayabusa

Earth the model thoroughly I used to only Earth the engine to the tail transmission box now I Earth engine to main shaft > main shaft to tail transmission box (tail drive gear bearing housing) tail transmission box to boom then boom to plastic tail box or metal box then check it with a multi meter for continuity its safety first every model I own has been done this way . I danced the model on and off the ground bang big static discharge
