This plane flies very nicely with an 8lbs-thrust pulsejet (PJ8) but I thought I'd use it to test my new 12+lbs design. Unfortunately, the high thrust line combined with the increased force from the more powerful engine meant that it wouldn't rotate on the takeoff run.

I should have cut the throttle after it wandered off into the long grass and bent the undercarriage but I thought I'd keep trying (big mistake).

When I finally aborted and cut the engine, the model lept into the air because the force holding it down was suddenly removed.

I think it's fair to say that 12+lbs of thrust is a little too much for this model. I'll be sticking the PJ8 back on for future flights.

  • did you think about maybe some kind of "thrust vectoring" system?? - if you can get it off the ground, it'll go like a rocket!!

  • @AngryJoeMan I did get it off the ground -- check out the flight video on this channel "Long ez now very fast"

  • Total pilot fail.

  • No, it doesn't! What is your explanation for how CG plays a role in this?

  • @ItzMyCore Please use Google, and look up the difference between a rocket and a jet engine. Then, read the poster's comments on the video describing what happened. Thanks.

  • PENIS

  • this not only due to high thrust but alsi the placement of engine is not correct on this design...
