With 29 parts, this is suitable for the 30 part challenge!

The Big Drone is an experimental drone that has both jet and propellers. The Prototype has only propeller engines, but that was not enough power, so it has five propellers, four jets. It is the first Londerburst with this design.

Controls:

normal.

Notes:

it does not have turnable landing gear. If you want turnable landing gear, you have to do it yourself.

Known bugs:

Rear landing gear will sway left to right after landing. Fix problem by retracting landing gear and extending it again (nope, it will not damage propellers). That may not work well, after you extend it, it may go bouncing again, but this is the only way that I can find.

Otherwise,

Enjoy!
