I´m useing a Hacker C50 13XL Competition in my Genesis F3A. The motor is great, lots of power. I think that you will be fine with your choice no matter wich one you choose. The difference is that the Plett. is an outrunner with virtually no maintenance. The Hacker is an inrunner with gearbox. Every 50 flights you have to re grease the gear box, not a big deal but you have to do it. In the battery section I can´t help you because I´m useing Thunder Power ProLite 5S 5300 mHa 13C (X2). Props 20x15 and 21x14.
