I got plans for A10 Thunderbolt II. It`s an awesome, but simple to build RC plane! This was a model I wanted for a long time. The build was ok, not too much work. The model was reinforced with balsa wood. No rudder servo needed, just ailerons. The motor is 1000 KV, but not suitable. About 1400-1600 KV seems optimal. It`s severely underpowered, but can still fly really well. That motor will be changed in the future. I do recommend building this, it`s so much fun to fly.
If you fly a drone or RC plane then you will really want to build or buy one of these devices because it can make a huge difference to the safety of your flying
