I think also that you misunderstand how notams work. Just because skydemon or whatever draws a 10nm circle around HusBos, that doesn't in any way define a volume of airspace that has to be avoided, or is closed to other traffic, or , importantly, that the gliders in the comp must stay inside.
The circle in effect says "if your flight takes you inside this area you probably need to know about this unusual activity". It's up to you to decide what to do about it (except if the notams is telling you about a temporary restricted area).
So definitely no need to cancel the RC comp!
Having held a PPL since 2004, I do fully understand how Notams work and I did, in fact advise my club of how they work and that this was not restricted airspace (e.g. TRA) but merely advisory navigational information unless, as you say, specifically stated otherwise. Hence, my advice to them as previously stated.
I also did not restrict my original question to competition gliders.
We see, in fact, Bosworth gliders overhead our field regularly as Bosworth is nearby. We even have the occasional Apache on a surprise low level exercise! Yesterday, when the question came up, there were more than a dozen gliders in the overhead. I also pointed out that, especially with aero tow, a glider would be unlikely to ever clash with a model flown by a model pilot unless the latter had binocular vision and a total disregard for the rules and no common sense!
Sorry to change the subject slightly, but we in the organised, responsible and long established model flying fraternity, have enough problems with impending legislation threatening our hobby created by the recent arrival of a tiny minority of irresponsible “loners” misusing multi-rotor “drones” fitted with on-board live video cameras ((FPV).
The fact that someone in my club raised concerns with me about the NOTAM is testament to the diligence of the overwhelming majority of model flyers who have an exemplary safety record and would wish to retain it without being unfairly penalised.
Back to the original subject, I’m much clearer now and, once again, many thanks to the contributors to this forum for saving me, once again, from extended research!
