My only comment here, is from personal experience. It might not be wise to use exponential on the models maiden flight.

Why? I nearly lost a giant scale model on its maiden flight because of this several years ago. On the maiden flight, I ran out of elevator trim adjustment to keep the model from diving. So, had to hold up elevator to keep it level.

And, with expo set to 30% on the elevator function, that put the transmitter in the quick response of the expo, where just a minor movement of the elevator stick resulted in major movement of the elevator servo.

So, every maiden flight since, no expo on either the aileron or elevator servos!
