Is the Mcx the most stable heli there is? Looking for a VERY stable heli for my 12 yr old special needs child. She hates the simulator and my Mcpx is just too quick even with the rpm way down and rates way down.. She is basically a 6 yr old in a 12 yr old body. I know the Mcx is stable, but is it the most stable you know of? Appreciate any info.
