I bet you'll find the trainer as exciting as you want for the first flights. One of the great things about this hobby of ours is that there are so many challenges, at whatever stage you have reached.
Also, you won't find any so-called expert worth listening to who looks down at your first attempts at flying. He will know that the ground is just as hard for his 1/3 scale aerobatic model as it is for your trainer.
