Simple Delta Model Development

Simple Delta SD5 based on MAV model, has not enough power to climb. Moments of inertia were increased to that of the SPORT model, which may make it too sluggish, however,  the power parameters need to be adjusted.

Now we come to the power settings

<power units="1">

      <automagic F="0.222411" V="11.076536">

        <battery throttle_min="0.0">

          <automagic T="420" />

          <shaft J="0" brake="0">

            <propeller D="0.06096" H="0.042672" J="0" n_fold="-1" />

            <engine>

              <automagic omega_p="2827" eta_opt="0.78" eta="0.7" />

            </engine>

          </shaft>

        </battery>

      </automagic>

    </power>

We ask ChatGPT to interpret this, and changed th epropeler size from 6 cm to 12 cm. Roll rates are very low due to inertia, and the plane floats and floats, displays strange charactersitics when belly landing


The provided configuration file seems to be describing parameters for a radio-controlled model within a simulator. It appears to specify various aspects of the model's power system, including the motor, battery, shaft, and propeller. Here's an interpretation of the parameters and how you can increase motor power and propeller size:

To increase motor power and propeller size, you can consider the following modifications:

Remember that modifying these parameters should be done cautiously, as changing one component may require adjustments in other components to maintain balance and efficiency in the model's performance. Always refer to the manufacturer's recommendations and guidelines for your specific radio-controlled model and simulator for safe and effective modifications.

Simple delta planes, sometimes a single sheet of foam board, are interesting for their ability to be built quickly and fly slowly if needed.  Could this be a good trainer? I build one for CRRCSIM.

First, some example models:

The last one has a 30 inch, 76 cm span wing.  It flies slow enough, so anything with similar wing area should fly the same, with proper stabilizers.  It is somewhat of an experiment.  The Boeing Microfighter has a span of 5 metres or so, and the Mirage III 8.22 metres, so that leaves some leeway for a 1:10 scale model.

The weight of the model is not known, but the author has listed the components 

Motor: BE1806-2300KV Prop: 6x4 Battery: 850mAh 3S Radio: FlySky FS-i6

The motor weighs Weight: 22g 

And the build thread: https://www.rcgroups.com/forums/showthread.php?2145562-SIMPLEST-simple-delta-with-simple-plans/page3

All that remains is to build a model to similar dimensions and add some scale details, then edit the configuration file of the SuperZagi.

Choose a suitable scale model..

Preliminary design with a flat delta wing and flat sided foam (recylceable alternative better) and a roll of card for the exhuast

Need to design space for the battery, receiver and ESC and wing cutout



For the 3D model, 3D versions of the RC components are also to be created for planning purposes.

Motor: BE1806-2300KV   Dimensions: 23 × 21mm

Prop: 6x4  6 inches = 15cm

Battery: 850mAh 3S

 Dimensions: Tattu 850mAh 3S Lipo battery dimensions is: 59*30*24mm/2.32*1.18*0.94inch; Approx Weight:85g/0.19l

Radio: FlySky FS-i6

Receiver:5.1 x 2 x 0.01 inches
