Hi Ashley.for sure it needs a lot of tinkering in the sinking department.the servos are in and the control runs are done.plus the ballast tank is fitted,i just need to fit the drive battery and the drive motor battery and the receiver and the speed controllers,then on to trimming and i need it all done for the forces in the field event this year. cause i promised it would be ready to the club boss man.no pressure then regards sammyk
