On a new model of a type I don't know I usually set full deflection to whatever the manufacturer recommends (or about 20 degrees each way if I really can't find any recommendation) and then set up dual rates at about 60% of that in case that proves too twitchy.

So far that's generally been good enough to get a first flight which comes down intact and I can then adjust the control throws based on what happened.

BTW too little throw is not going to be a problem given that in initial test flights you just want to see what it will do and get it round and back down to a landing. Long turns and a gentle flare are NOT serious problems in this context .
