Quadcopter based aircraft model

CRRCSIM does not provide for VTOL to forward flight transitions.  The VTOL portion of the flight regime, however, can be modelled using the quadcopter file and a VTOL 3D fuselage, which provides useful practise.

Designing the model

Sizing is important.  Most quad copters including the toy ones have a width and length of about 30 cm. This is roughly the size of an A4 sheet of paper.   Zooming in will compensate for the small size of the model.   Lets call it the Delta VTOL 1.  The quad copter flight model is the basis for this VTOL, so transitioning to normal flight is out of the question, however a CTOL model can be built to simulate conventional flight.  Twin tails need to be added to the model

Each square in Wings 3D maps to 1 ft or 0.30 meters in the CRRSCIM flight simulator - this is quite evident when looking at the smaller models which have a wingspan in the configuration file of 3ft or 1 meter approximately.  

The quad copter configuration file does not need any changes except to reduce the weight of the quad copter to make it easier to land - any vertical speed greater than a set limit and the model will crash, not bounce. Setting the exponentiation settings on the controls setup should correct the problem.

Flying the model

Once the model is set up, flight tests and videos will continue.  The model will be hosted on Source Forge like all the other models.

So far flying the VTOL has been fun. 


The VTOL quad copter model as this graphic shows, spans 3 squares, which is 3 ft or about 1 meter in CRRCSIM. Clearly not a typical quad copter, so the size must be reduced to 30 cm.

Development models of the DELTA-VTOL-2021.  

Initially planned to have  mini quad at the center of the wing, it will be now made the normal quad copter size, 30 cm by 30 cm and zoom adjusted.  The small size of the models make is more difficult to fly.
