I have to say Ko Helios is the most comfortable radio I've ever held. The drop wheel with adjustable angle gives a whole different prospective to driving
I may be wrong; But I believe KO applied for a patent on how the drop wheel
angle can be changed. So I'm not sure if futaba can use the same mechanics to produce an angled wheel. I believe the 4pk will have a adjustable angle forward to back and not pivot like Ko Helios. But I may be wrong.
