4#3 b can't go inverted, 4G3 can. But as they are one of the hardest heli to fly due to their size and design. I agree with sfdo and ledtech brother DONOT start flying with these two heli or you will be spending more time fixing it than flying!!!! go with something like esky lama and walkera lama. As these models are more robust and much better for beginner.
the answer is no, i am new player, very fine with Lama2, but 4#3 is just a joke, totally out of control. So still playing with flight SIM. Don't start with this, i can sell it as 2nd hand to u. haha
