Tried to build a plane..... Ended up with my first SSTO

Great looking design! I specialize in making SSTO's that end up being planes.

Mine have this annoying tendency of transforming being reassessed into multi-stages-to-ground vehicles on reentry... :/

It looks like a very stable design, by the way.

Two hints:

  • If you get a hard tendency of slidding off the runway on taking off or landing, make the main gears closer to themselves. The widest the gap between them, more stable on touch down but more instable while rolling fast as any small difference in friction will push her to one side or another.
  • Moving the rudder to the fuel tanks on the side of the engines (making her a dual rudder, and moving them a bit farther from the CoM) will greatly enhance vertical stability while rolling on high speed (when the front wheel loses authority), and will help prevent her from "dutch rollling" in high speeds while flying (the craft "dancing" from left to right).

Cheers!

yes, it did try to slide off the runway. Thanks for the hints! :D
