yes,they were supposed to be! i try to keep extra parts on hand.when neither of the 2 motors would help my falcons i ordered a new battery and it performed the same way as my other 5. then i tried another receiver,still no help. sounds like i have 2 bad motors out of stock but the warranty is only 30 days and that is the problem with trying to keep parts like that on hand. i can't remember the order number anyway.
thanks for all your help guys,i guess i will try to order a couple more motors.
