Hi Jonny,
The 4PK looks awesome but why did Futaba decide to go without a module? Aren't module-based radios better for taking advantage of new technology. Look how the 3PK has been able to evolve - from crystals, to synthesized, to Spektrum and now Fasst, all with the same radio. I guess it's hard to imagine Fasst could be improved on but who knows what's around the corner.
Also, what's the Hara trigger? I'm assuming it's a tighter trigger but did Hara do something special with his trigger on the 3PK.
Thanks
