This site has a much different "flavor" that any of the others. The vast majority of traffic here is strictly about C/L stunt. Building, flying, engines, etc., whereas the others have much more "non-stunt" traffic.
As to your question about asking for answers here, I do not have a clue as to why anyone would NOT ask it here. Looking at the member base, the very best knowledge about any aspect of the event is contained in our membership.
Without causing hard feelings with anyone, I would make one observaton from all the years I have been going to online forums. Some of them contain "instant experts". People who may never have actually built a stunt plane or flown in a contest. These peopple sometimes will answer questions as if they are knowledgeable about everything. When, in fact, they are simply perpetuating bad information.
I do not see that here.
