I had one of the EZ ARF F-16's. It flew OK once in the air, I think this one with the motor in the nose would be much better. I used an OS .28 or .32, plenty of power. The problems were all related to the pusher motor - fuel draw / richness on climb / cooling and a serious prop clearance problem. I would use an OS .32 FSR or Sx for the best combo of lightweight and great power.
