A 1400kv motor, but what size? Is it a 2212 1400kv? The kv just indicates how far a motor tries to spin, but not if it’s actually capable of doing that fast with a given prop. If you put too large of a prop on a small motor, it will burn out from trying so hard to turn at that rate.
If you have a 2212 1400kv with a 2200mah 2s, then that might work pretty well on a number of FT trainers. Most of those call for a 2213 1000kv with a 3s battery, which would be similar.
If it’s a shorter profile battery, then you could probably do a Scout (not mini or XL, just the normal one). That’s an excellent plane for beginners that would use that size motor (assuming it’s a 2212!).
