I've decided on the FE 30 ... thanks for all the great input ... tough choice between the Insane FE 30 and the PT SS21. Is there a suggested setup sheet for the Insane FE30; ie. specs on exactly where to position the major components (motor, servo, battaries, ESC) to obtain optimal balance and speed? Or if not, can any of you guys who have been running the Insain FE 30 make recommendations on the placements of the components? As always, all input is greatly appreciated
