I did the front diff with the bad horsie difflock but not sure if its going to work. It is a hole lot tighter but it will still differentiate. Definatly not locked. I made my adaptor plate out of some 2.5 mm carbon fiber and a peice of billet plate. Turned out nice but I might cut the spacer down to keep the weight down.
I am also having second thoughts about running the jconcepts body because of the flat not so aerodynamic nose. It does have alot lower roof line than the slipstream though so I really dont know if it would make a difference. I went ahead and ordered another slipstream, maybe I can make the new one work better. I think the front wing design is out though unless I need some front down force which I think the body should take care of anyway. Here a pic of the carbon fiber adaptor plate I made. The billet spacer underneath is needed because the monoblock is pretty thick. The carbon fiber peice will make a good place for the gyro to go when it shows up.
