I have been flying a Mini Titan at a Munipal Field for a while, and had perhaps 1 or 2 problems out of 100 flights. This field is used by others for R/c flying. However, it is fairly close to radio transmitters for various agencies.
Out of perhaps 5 flights with the Innovator, perhaps three ended with strange flight characteristics, and one major inverted crash into the Police Department metal roof, which is a story in itself
Anyway, I suggest leaving fields alone that have ANY suggestion of transmitters around. This may also include flying in school gymnasiums, as I have seen some You Tube videos on some flying problems in these areas. Bear in mind that any Municipal area. building more than likely has some kind of radi frquency setup, be it communication or security.
Another thought I have is that in the Innovator, the program is in the Heli... so, rather than flying the Heli around, perhaps we should look at this in the way that the PROGRAM is moving around, which is normally in the TX. Sort of like doing a range check, and then moving to another location for flying. The brain of this thing is constantly flying in and out of possible RF interference. Any official comment on this appreciated.
