I have had a G2 for about 3 months now and have still not been able to even get it to hover. I have upgraded the head to CNC, upgraded to brushless, but still no fun. I have a Blade CX2 4 channel that I successfully fly all around the inside of my house with no problems. Has anyone had any experience with the EXI 450 helos? Which is better the MB450 or the 450ZL Pro Edition? Also will the parts from my G2 work on them. Mainly the servos ... I'm pretty sure everything else will work.
