RD-5 - Codename: Knee Biter - Status: Testing

Estimated cost to build this model today.
$424 USD

 

The primary research objectives for this model are :

  • Split motor mass - to examine the idea that splitting the rotating mass of the motor and propeller between the upper and lower portions of the prop plane will decrease vibrations and increase stability
  • Test Soft mounting of props - Examine how using the Oring prop saver mounting technique will reduce prop breakage, arm breakage and improve field change of props.

 

History: RD5 was built from the broken and remaining parts when RD3 crashed and was converted from an OCTO to a QUAD.

RD5 Testing 4 motor 8 prop config

Octoquad RD-5 Aeroquad V2.0 - 8 Propeller - 4 Motor - Coax Config Flight test

Testing the effect of adding additional 4 props same size and pitch and orientation to flight characteristics. Flight time dropped from 8 minutes to 6 minutes but lifts easier and flies more stable in stable mode on default settings, no tuning or balancing.
