several points.
RC Servos to make the rocket guidable is a questionable idea even if it were perfectly within the code.
The rocket has a boost usually less than 3 seconds. You are not about to guide anything in those 3 seconds, the entire idea is to have the rocket stable at speeds greater than 30mph. Taking it straight up.
After those 3 seconds you are talking about a small rocket that is traveling directly away from you at likely over 100mph ( and more likely over 400mph ). and at an altitude of several hundred feet.
You would have to know the orientation of the rocket ( not likely ) as it turns. basically you arent going to guide anything on the way up, except to make an otherwise stable rocket head off in an unexpected direction ( not a good idea )
On the way down you have a recovery system. if it is a parachute or streamer than your fins wont do squat.
The one application that would work well is servo controls on a glider recovery.
Recently I have been building boost gliders. The Quest Intrepid is a good and cheap example of that kind of glider. ( however I extended the elevators and made them adjustable ) Gives great flights.
My next boost glider is going to be a scratch built design but much larger, glider based on a 29mm body tube.
After that I may build a glider with RC servos for controlled flight.
There is a place in rocketry for RC controlled surfaces, but it just is not the fins. That is going to just destroy your rocket, and possibly get someone hurt.
Just a tip
And by the way, it is not the age we live in that makes it a problem, that has been in the code for over 30 years. And for good reasons, they are trying to make sure no one builds a rocket guidance system for hitting a target, basically a guided missile. That kind of effort would bring the authorities down on the entire hobby in a hurry, which is why the rest of us are telling you dont do that.
But look on the bright side, there is a place for servo controlled surfaces, try a project with that in mind. But go slow, trying to bite off more than you can chew will hand you a drastic failure and discourage you. Start slow, build something simple, then build something a little better.
As series of successes using a small amount of money each time is a whole lot better than shooting for the moon with no experience.
