It is not particularly helpful that hearsay and faulty inference is being presented as worthy of conclusion - for example noting that Spektrum led Joe Nall crashes until this year when Futaba took the lead. Well, spektrum was first to market and very likely had many more units flying than futaba in the early years.

Regardless, without knowing the following

- Number of flight minutes on each system
- Historic crash rate per flight minute of each system
- Standard deviation of crash rates

Drawing any conclusion based on a relatively small number of crashes associated with a particular radio systems is impossible.

Confounding this is the fact that RC airplanes crash for a multitude of reasons, post-mortem analysis is frequently inaccurate, and there is a behavioral bias towards blaming radio systems.

So, I find the indictment of 2.4 a fail - scientifically and empirically. That said, if something better is in the pipeline great and if you prefer 2.4 or 72 then fly your preference.
