Coming back to this, I contacted the RAF model flying assn but no response at all.
For the BFMA is he a specific Cadet Sqn membership, or is it a question of an individual joining?
Lastly has anyone successfully gone through the ACTO75 / MoD permissions process?
Trying to get all this in place for the autumn.
From the BMFA website. https://bmfa.org/Join-Renew/Membership-Types
5) SCHOOLS AND YOUTH GROUP MEMBERSHIP is open to bona-flde school model flying clubs and clubs organised by recognised youth organisations such as the ATC or the Scouts. The minimum number of club members is one individual senior and four reduced rate juniors. The juniors need not be named and their membership fee will be one third the current junior fee rounded to the nearest pound.
This gives the club full affiliated membership of the BMFA and at General meetings such clubs carry one vote. For the senior member and one vote for every three reduced rate juniors subject to a minimum of five votes
Any reduced rate junior may become a full member of BMFA by paying the full junior membership fee. Any such junior carries one vote at General meetings and is not disqualified from membership of their group. See also the section on insurance.
Thank you that is exactly what I was looking for.
