There are at least half a dozen active clubs in NB affiliated with the National orginization,which is the Model Aeronautics Association of Canada.WWW.MAAC.CA
I cant tell you which is closest to you since you dont list your address on your website or RCU profile.
With your experience with hoppy copters,radios,where to buy supplies,etc are not mysteries to you.You already have found the most currently helpful internarional RC website,here at RCU.
I strongly suggest you contact a club and start asking questions there.If you need help the Atlantic Zone Director is a very active helpful fellow,who happens to be VP of MAAC at this point.If you wish I can steer you too,as I am a Zone Director in Ontario,but I lived in Saint John for a couple of years and I know the geography of the Province well.
The radios you own are the same ones used for fixed wing flying machines and can be adapted.I dont know where you fly your copters,but you have the ability to interfere with other flyers and they with you if you are close enough,and that is reason enough to find out where the closest club is located!
