</span>
A few years ago my family got together to buy my dad a remote controlled helicopter. We wanted to get him something good, so I went online and shopped around. I bought him the Heli-Max Kinetic .50 ARF Nitro Heli. What I didn't realize as a noobie was that for $400 we were getting a frame, not a complete piece.
It has since sadly become a bit of a joke with our family. Dad's incomplete gift. A sad frame with no engine.
I truly intend to finish this for him, however. The only thing is, I'm still a noobie and need to be sure what I'm getting him will work.
I've looked online at some setups and tried to compile something similar. Below is what I've got so far.
Would this work well for him? Any suggestions to make it a more stable flight for a noobie at the controls?

Thanks in advance for any help!</span>
