I have the MSR for the house, Love it .
A Raptor 50 for out side, love it. Still learning training gear is off.
I bought an SR,Great looking bird, POS IMHO, tail motor burned up.Very temperamental, Does not take a crash well at all.It could just be me.
Just got a 120 to fill the void and its a blast.
Helps me build confidence when I take the nitro out.
Some love the SR and some hate them.
I was disappointed.
