The bird is a Trex 450 SE V2 clone from HK.
I am not a fast forward pilot, nor 3d, I can hover quite well

What I want, is really only to add self leveling to make this more idiot proof, when I got my quad working with LEVEL on, it was a thing of beauty. I was able to transition to forward flight much better. I have now decided to upgrade from the HK MWC SE to a Crius AIO Pro.
So long story short, I want to take my old MWC SE and use it on my stock CCPM 450 to get autolevel.
I found a thread that said there would be problems, but I decided not to just add to it and start my own.
What is the simplest and cheapest, keeping with all the stuff I already have (if possible) way to put auto level into my CCPM heli?
I blew all my RC budget on the AIO Pro kit

one thing I found that was pointed out, would be the lack of HH without a heading hold gyro on the tail.
the MWC SE has a digital compas, why could it not manage HH with that?
Thanx in advance
