Red Hawk

Introduction:

After failing to launch white hawk due to torque roll issues, I wanted to give it another shot with the same 1407 motors and different props. Not giving up and retrying is after all the key to success in this hobby (and pretty much life in general).

Components ($30):

  • 2x 9g servos
  • SZ speed 1407b 4000kv
  • FVT LittleBee 30A ESC 2-6S
  • 3a 5v UBEC
  • 4 channel dsmx receiver
  • 5x4.5 carbon fiber prop
  • Dollar tree foam board
  • 2x push rods
  • Colored packing tape
  • bamboo skewer (spar)

Conclusion:

It was a quick and dirty build with an emphasis on speed instead of weight. It came to 103g dry and is capable of 2-4s performance. The basic shape is that of the corsair except the foil thickness has been increased. Elevon size has also been extended by 5mms and the nose was extended for balance using different types of batteries.

The maiden was highly successful and it flew perfectly on the first flight even though it was in 15-20mph winds. The power was pretty amazing as I went with a 3s battery with lots of punch. Pretty much unlimited vertical until it became difficult to determine orientation using visual LOS. With the increased elevon size, it has amazing roll rates and great elevator authority. Going forward, this will be the basic design for all my wings using different motors.

This of course leads me to wonder if the torque roll issues with white hawk were attributed to the prop... Once I have the time, it would be good to test that.
