Really interesting. I took my maiden flight at the disused Wisley Airfied, in Surrey. This was the test airfield owned by BAC, which became British Aerospace, and was the site of the test flights of Britains first "V" Bomber, the Valiant and the then radical airliner, the VC10.
I flew from the apron area that had the hangers located on it. Lots of flat highly reinforced concrete... everywhere! OK, so what's interesting is that I was really cautious - this was my first flight outside of the house and the Flight Sim, so I calibrated the compass and IMU.. the compass twice. Intake of breath and I got a green, safe to fly notification and entered auto takeoff. The aircraft rose up and at about two feet, it twitched violently to the right then left and then steadied-up. I proceeded with the 3 minute flight and it was uneventful (but totally am-maa-zing!) and the rest of the flights I've made, all so far at Wisley, have been incredible and again, uneventful. On the longest distant flight l've undertaken, running along the length of the 2000 metre runway, I did lose comms at the eastern end of the runway at 1000m but it did restore and then lost RC control, again for two or three seconds and it again came back. I'm wondering if the Wisley VOR, which is located at that end of the runway could've effected the signal? Be interested in your views. Also, could a Teslameter be of use to check the magnetic interference?
