The recommended prop on 3s is a 14x7 and 4s is a 13x6.5...5s 14x7 probably out of the question, but It should handle a 14x7 on 4s as I think specs are conservative for that wind. Keep in mind it's weight is 177g, which the plane will handle, but the recommend motor weighs 143g. IMO for motor this size on 5s and a 14x7 prop you will want a KV in the 540 to 560 range, but depends on specs and climate. Again I think extreme flights specs are pretty conservative. For example my motor is on 4s 720 kv spinning a 14x7 (over spec according to some, but with over 400 flights on setup). Take that KV 720 x 4s / 5s = 576kv, which should be extreme upper end. Others recommend 680kv on 4s, so 680 x 4s / 5s = 544kv, which should be in the zone. Just be aware of the specs and tempetures.
