There are a few points that emerge from this thread.
1. You should only comply with ATC instructions if you are able to.
2. Instigating a go around from 400 ft agl in a small light is no big deal.
3. Being asked to turn to the right or what ever instruction it was in this instance must follow killing the decent and at the very least achieving S & L flight BEFORE you commence the turn.
4. For craps sake, don't start that turn before you kill the decent. Dig out the principles of Flight book and remind yourself of what happens to lift when you bank the wing. Mind your speed.
5. ATC issue instructions. Pilots behavior in accepting / carrying out those instructions determines the workload.
6. If you don't feel you can follow ATC instructions (AND THIS IS AN IMPORTANT POINT FOR ALL, PARTICULARLY STUDENTS), then don't. In this case, put it on the ground and allow the following aircraft to make the go around. Aviate, Navigate, Communicate. If you are an experienced, student or low houred pilot who cannot comply, avoid drawn out communication at all times, particularly 400 ft agl. Fly the bleeding aircraft. "Golf - Alpha bravo, unable to comply". Getting more chatter in your headset as a result (unlikely)?? Let us not write on your headstone that you exhibited good quality radio, but were a crap pilot. You are the captain. Behave like one and control the situation.
You will of course have to explain yourself afterwards, but without exception, I have yet to meet another pilot (plenty) or controller (a few) who would have anything other than helpful advice in the "de-brief" that would follow.
