When I installed the engine it created a nice smile on the plane, Looks like the Jokers smile I used Dubro Adjustable Control Horn instead of the stock ones and all 4-40 rods. The only thing else I didn't change was the rods for the rudder. This looked ok to use for the rudder. I had a hell of a time getting that 2" spinner to go over a 14X5 Pro Zinger prop. I had to chop it up a lot to get it to fit. I don't know of anyone that makes a small spinner to hold big props. Someone needs to come up with some of these as now a days almost all planes are being over powered.
