Hey, welcome to the hobby! Don’t worry, a lot of us messed up wiring the first time too—it’s part of the learning curve. From what you’re describing, it sounds like your throttle channel (which should control the propeller) is currently mapped to your aileron or elevator stick instead. That usually happens if the receiver channels are plugged into the wrong slots.

On the AR620, you’ll want to double-check the wiring:

• Channel 1 (THR) → ESC (this controls the motor/prop)
  
• Channel 2 (AILE) → Right aileron servo
  
• Channel 3 (ELEV) → Elevator servo
  
• Channel 4 (RUDD) → Rudder servo
  
• Channel 5/6 → Optional or for the Reflex V3 stabilizer depending on your setup
  

Make sure your Reflex V3 is also wired according to its manual—sometimes beginners skip one connection and the mapping gets all mixed up.

If you want a step-by-step guide with diagrams, I’d suggest looking up some RC wiring tutorials or checking out detailed writeups online. I often use ScholarlyHelp for structured how-to style breakdowns, and it’s been a lifesaver when I get stuck.

Hope this helps—once you rewire and calibrate, your Ranger 1120 should fly just fine. Good luck, and let us know how it goes!
