Piston Power Twin engine Biplane

video of me building this plane

Info:

This plane is based off of my single engine version. It is significantly better than the single engine version. This plane is powered by two mechanical piston engines that spin in opposite directions to avoid uneven torques. These engines are pushed to their performance limits with massive 4 bladed propellers. At max prop pitch the blades are almost at a 90° angle with the incoming air. The plane can reach a max speed of around 115 mph in a straight line. I attempted to make it look halfway decent in this video


Controls:

If you forget the controls, check craft instructions.

  • Activate1= Open canopy
  • VTOL= Flaps
  • Trim= Prop pitch
  • Throttle= Engine speed
  • FireGuns= Start engine (Use with throttle)
  • Pitch, Roll, Yaw, & Brake= Normal flight controls

how to fly:

  • Hold space bar fireguns and then slowly increase throttle to 100%
  • Next start at default prop pitch, and then slowly increase moving trim up as the speed increases.
  • At this point, you should be able to pitch up a little bit and takeoff.
  • Once you're flying set, the prop pitch Trim to its maximum. (Note: Climbing is slow, if you pitch up too steeply, it will stall.)
  • To land, decrease prop pitch Trim and lower the flaps VTOL

notes:

  • This is not a replica. It's a fully original design.
  • For the engines to run, it does not require fuel, and it can even run underwater Note:(the starters won't work underwater.)
  • The Yaw control on this plane is surprisingly good. You can actually turn faster with the rutter, then with the traditional roll and pitch method.
  • Feel free to use this design in any of your own builds, although I would appreciate it if you credited me in the description. Thanks!

Enjoy!

    @SBACERT Thanks! Yeah, the torque is pretty serious.
