personal projects

I am looking to purchase a Flysky FS-I6x transmitter for a project that I am working on. The issue I keep running into is how I am going to control 4 separate servos with 4 switches. I need to turn a servo about 120/130 degrees from starting position and return to start. From my understanding...

I have been part of the hobby for over 5 years now, and recently I have been dabbling with foam and I had the idea of sizing up an FT design and glassing it & putting one of my 20cc engines in it looking for thoughts and opinions -thank you
