Similar planes comparison charts

Thanks to the specifications of similar planes, the range of dimensions can be narrowed, discarding the maximum and minimum values and adapting them to an increase in weight to up to 500 grams approximately, due to the added weight of the camera system.



Similar planes configuration chart
  (more models were checked but these are the most significant)


The sizes depend on the payload, which depends on the mission, the purpose that the plane is designed for.
As the plane’s purpose is diverse, let’s just say it must be able to climb to 100 meters at least, fly for 30 minutes to 1 hour non-stop with turns, ups and downs, and land smoothly. The takeoff can be made by hand-launch. The range depends strictly on the antenna that will be transmitting images from the camera.


Components from similar planes


Now for these components, an in-depth analysis with different models for each component is required, to know which ones are the most suitable ones for the mission.

Similar planes specs

The fact of not having a single idea about how radio controlled planes work, an inner study is required. Several features and specifications of these planes are going to be compared from existing planes that match the glider type.

Looking around the most famous websites for RC planes, there are a few that have the most similar configuration. It doesn’t matter if they are not designed for FPV because this is not such a difficult implementation to a glider compared to taking an FPV plane and transforming it into a powered glider.


This large powered glider (2.4 m):
