This hull will be for the FE or nitro scalers. I have spent alot of time in the design of the insert that will be for the nitro or the electic side. No more full engine rails like the Gen 1 , just a engine tray insert. Also there was alot of work and time that has went into the bottom of this hull and sponson area's. So thanks and I will keep the pics coming Doug Shepherd Madison, Ind
