Hi Steve
I have had a portable PowerFlarm mounted with Velcro on the glare shield above the instrument panel in my glider. It is mounted at a height close to that of my eyes and is carefully orientated so that there is the least brightness attenuation when using Polaroid glasses. It is very very marginal because of the small screen and the tiny characters and symbols and in my opinion much inferior to the original Flarm used in the rest of the world.
There are other issues but I won't go into them here and now.
Would I purchase a new PowerFlarn if I lost my old one? No I would buy a Zaon MRX PCAS which I used for 3 years before installing the PowerFlarm. PowerFlarm is a work in progress which is progressing extremely slowly. I am not convinced in its present incarnation that it could be or is a viable product. I have kept mine because I would truly like PowerFlarm to be successful but I think they have got themselves into deep water biting off more than they can chew. I would like to be proven wrong but I don't think so.
