Titan Avenger VTOL Kit

$14.99

The Avenger is one of our most popular models. We are excited to officially release the VTOL kit which turns the Avenger into a 2+2 Tiltrotor VTOL. The front two motors can tilt while the rear are stationary. It also features many optional noses as well as landing legs if using an underslung gimbal or payload. The kit includes STLs for the new wings and all necessary mounting points for the VTOL booms and optional legs. As a bonus, we’ve also included a new wingtip which gives it an aggressive look. You’ll need to already have purchased an Avenger to use this add-on kit. Existing Avenger customers need only to reprint the wings in order to get full VTOL functionality. A big thanks goes out to Edwin At for beta testing this beast for us!

Please refer to the instructions below the images as well as Ardupilot setup tips for additional guidance.

Requires additional purchase of the fixed-wing Avenger.

Ardupilot setup tips:

Official Ardupilot documentation (also see tiltrotor docs) is a great source and has all the information you will need. Below are some parameters you’ll need to set which are specific to 2+2 Tiltrotor VTOLs.

Q_ENABLE = 1

Q_TILT_ENABLE = 1

Q_FRAME_CLASS = 1

Q_TILT_MASK = 4

Q_TILT_TYPE = 2

Q_TILT_YAW_ANGLE = 10

Recommended Motor and Prop

  • Motor: BrotherHobby 2816

  • Prop: 12x6 CW / CCW

    This is only a suggestion. Feel free to use any other motor and prop combo that you find suitable for your AUW. Remember to choose motors that can provide close to twice the thrust required for hover for best results, especially during backtransition when the battery is at its weakest point and may not be able to deliver the same wattage as on takeoff!
