First Mods

After first flight, comes first mods 😉

One of those things you know in advance about this hobby: once you have a flying system, you recognize opportunities for improvement, which leads to modifications. That's just as sure a bet as saying you will crash at some time. 

In this design, I initially had the battery placed between the top and the bottom plate. But there was no good way to secure it such, that it would not slide forward or backward between the plates. And a slidings battery is disastrous for the Centre of Gravity being as good as possible in the middle, as the battery is by far the heaviest component. There was not enough room for friction material. Hook-and-loop would be even thicker, and require the battery to be peeled off, for which there was no room either of course. So the battery had to go under the bottom plate, with hook-and-loop, and a battery strap for added security.

But landing on the battery is not the brightest idea, so I ordered some of those loger legs that screw under the bottom plate (and some spares, as I predicted these to become "consumables", just like props 😂)

This made some drastic changes to the Centre of Gravity, and Roll and Pitch inertia. So, you guessed it, another round of PID parameter optimization was in order. But this is one of the Nice things about getting your own creation to fly (properly), so that.'s OK 🙂
