"What should YOU do?" You should do whatever you think you really want to do and what you think you will like. Flight Instruction is a demanding thing, if you wish to do it well and PROPERLY. The psychology of learning can be extremely different within different personalities. That can create a large chore for those that think there is only one way to do things and that is his(her) way.
The aviation student can be a handful especially in the RC world where many individuals have never been subject to any form of personal discipline in the realms of being the person totally responsible for the behavior that a toy RC airplane can present. [X(]

I have instructed student RC pilots since about 1972 when there was no such critter as a buddy box. The differences in individuals that the RC Instructor has to contend with are many and very different from student to student. As an Instructor in the USAF, both T-33 and T-38, there were always individual differences, however those students were a select group, and they knew that there was but ONE Boss in that airplane. Not so on the RC line.

So brace yourself to the fact that you not only need to be "Boss", yet still be friendly-firm. Not always easy. Now you need to be able to give good lesson briefings, you need to understand basic aerodynamics, how to cope with a dead engine forced landing, when to take control, how to find a student's weak spot and provide more than one technique to correct such deficiencies, plus how to set up and trim a new model. You should be able to brief Pitch, Power, and Bank from the real world, not just formulas. You should know that while the lift equation has a number of factors, that a pilot controls only speed and angle-of-attack, the really important factors in the equation.

The one thing that I always do is to assure a student's Trainer doesn't have a Center of Gravity (CG) aft of 25% of Mean Aerodynamic Chord (MAC). After several flights you can start moving the CG aft a small bit at time, but never go aft of 30%. Far too many commercial kits/ARFs show CG at 35%. That is a crash about to happen. I see it frequently, but just not any student I instruct.

If you are really new at the game, just remember that YOU are also LEARNING. If you goof, admit it, do NOT make excuses. Then you will find a student wanting to be a part of the flying and will have even more self-confidence. That actually never stops. No matter how good you are, you're going to mess up every so often. Be honest about any goof and everyone will be on your side. Try to make excuses like, "The wind got it." and such, you will only be suspect! If the wind is too bad for your ability, don't fly. If you can't hack the day's cross-wind, stay on the ground. That is a sign of GOOD JUDGMENT" which is a sign of a good pilot, not an excuse maker.

So, If you wish to instruct, I'm betting you will do very well, simply because you wonder about it. That signifies a desire to learn which is a vital part of starting something new. Enjoy!
