Hi!

I am flying Control Line models.

(link for example on YT: Control Line Handle Talk First Maneuvers - YouTube)

And now I wanted to develope controller for eletric version :).

Maybe a little explanation, what is the problem.

When model is flying on level, there should be for ex. 60% of power.

When I climb, I want to have 100%, and when diving, power should be reduced for ex. to 50%.

Of course, there are ready to fly controllers, but cost about $300, so I wanted to try to make my own ;). I know, that it will be a tough problem to solve, but maybe we could do it together. I plan to make it open source -> it is for hobby!

I read a little about it, bought MPU6050, read accelerations, but it was 5min to do it . But what now?

From everything what I read until now, it looks like a 1 year project for me... Programming is not a problem, but what to do next in general .

My ideas:

- NOT to start with Euler angles, becouse there will be problem with flying straight up.
- Quaternions?
- There will be a lot of dynamic moves (so a lot of acclererations) - is there a way, to get rid of them, and stay only with gravity vector?
- Is Atmega328 and MPU6050 enough for a such task? Models flies around 80km/h, so sampling must be pretty high to keep up with plane moves...
