Retro Rocket Engine Failure(s)

[JoeBo]

Hello!

Quick question regarding our new Retro Rocket build: my son has burned out TWO new engines in two consecutive flights. Today’s flight was less than 1.5mins long. Plane is set up to FT’s specs with all their components (matched ESC, engine, prop and recommended battery in the appropriate power pack) w/ thrust vectoring mount.

The engine gets good airflow based upon the design. Pic of the recommended motor attached. Thoughts? Seems to be a small motor for the design of the aircraft but again, is the recommendation from Flite Test.

Thoughts on possible issues? Thanks!

I've had the same problem. Flew about 1.5 minutes each time.

Have you guys gotten in touch with FT support? It looked like the FT team was able to fly the Retro Rocket for longer than you're describing without motor failures in their videos. Maybe they can replace the parts for you, they've helped me out in the past.
