Dennis,
I had Kuntzleman twin flash strobes fitted to my previous trike (Edge 582), one on top of king post, and another just in front of the nosewheel. According to other flyers, they did make a difference in anything other than bright sunlight conditions.:thumb_up:
That is enough for me. If they prevent just one mid-air, or incident then I consider it money well spent. I shall be fitting the same setup to my current trike as soon as I have resolved my radio issues (one step at a time).
I heartily endorse Crezzi's recommendation to read through the BMAA's minor mod on the subject. It will cover issues that you might not otherwise consider.
By the way, on my 582, I mounted the driver box all the way forward in the nose, and then subsequently had to move the radio antenna from the nose out to the mainwheel, to minimise interference.
Hope this helps.
Safe flying
Kev
