To be honest. The electronic items in the copterX RTF kit are sure not the best..... It really depend if you are like to do normal flights it will do the job. But if you are looking for ultra 3D do not use the copterX electronics..... As far as parts goes as the copterX pro v3 is an earlier clone of the trex pro. So the parts are different than current model. The latest one will be the copterX Pro V5 DFC which is a align PRO DFC clone.
