In my club (G&E VVM, Holland) we recently had problems with transmitters that were modified with a DIY Corona module. While one member was flying, another one switched on his transmitter, started up his model and taxied with it before both planes went out of control. The first member saw his plane crash into a water surface.
A month earlier, I myself nearly lost a glider; it was launched piggyback, and I had checked the controls just before launch, but when it was released a minute later nothing worked. As there was one other member on the field with a Corona-modified transmitter, I later realized (after hearing about the recent incident) there might have been an interference issue. (My glider came down out of control and crashed into a tree, undamaged).
There has been a third incident too but it is less documented.
Yesterday evening, at a club night, three members brought their Corona-modified transmitters (one Futaba, one Graupner and one Multiplex) plus receivers, and we tried to duplicate the interference. But everything worked the way it should.
It is unlikely that if these incidents were really Corona-related, ours would be the only club where such things have happened. Which is where this forum comes in handy... has anybody here witnessed an incident where two Corona modules might have interfered?
