Welcome @SparkyFPV, I’m based not far from you (other side of the brook, in Sale) and I am that very guy you met in the park earlier 
I don’t know much about self-builds so can’t really compare, but yes, I thought it was very steady and quiet too. There are quite a few self-builders here, feel free to share in this thread or maybe via So... what's on your bench at the moment? - #186 by notveryprettyboy.
