A special heli radio that allows you to adjust the throttle and the collective pitch separately, like you can on a real heli?

Perhaps a collective pitch control stick that you can twist clockwise and counterclockwise to adjust the throttle?

Or perhaps another control lever with which to do it?

thats funny you bring that it... i actually WAS just thinking of this yesterday when i was out flying.

pretty much what you were thinking, have a knob at the end of the collective stick which adjusts the throttle.

i couldnt think of a reason for it though aside from novelty's sake, especially 3d flying, but maybe for scalers..

Err when flying a full size heli you have the indicators to tell you the match between the engine rpm and the rotor rpm.

With your idea there is the possibility of not decreasing the engine rpm sufficiently to match a reduction in pitch. This might then lead to over revving an unloaded engine. Heli goes one way, piston goes the other way

are these full range knobs you speak of? or hover pitch and hover throttle?

ie could you full control the pitch range via these knobs?

No they only effect the pitch and throttle curves around center.

Just a thought..
But isn't this the purpose of pitch curves/throttle curves?

Exactly.

You can fly with out a gyro too but why bother?

That would be a good idea if you had a way of constantly monitoring engine load / rpm

Just how many spare fingers or hands to you have to have to run this setup? And do they need to be in any particular place?

What's the advantage for the added complexity, and why can't this be accomplished by using a properly tuned governor?

Not too hard to do this with any decent radio. Put throttle on a slider or nob and leave collective on the stick. The fact is though, that these things are hard enough to fly without trying to manage your throttle curve dynamically.

You simply aren't going to be nearly as accurate as a decent throttle curves will be. And you'll be a heck of a lot slower. Even the worst governor on the worst tuned machine or 3 point curves will kick on your best efforts.

But its all about fun. No reason why you shouldn't try it. You might blow a piston or two if you can't get out of the power fast enough... but what the heck it's your heli. When you have it mastered unplug the gyro and do that manually as well.

Have a blast.

separate throttle
it's true, that real helicopters have the throttle and collective on the same control. Most engines are governed and as soon as you reach operating RPM, you, as a pilot, do not adjust engine RPM, the governor does it when you move the collective. It's mechanical until it gets to the fuel control (talking about Hueys), then the governor inside the fuel control takes over.

I have enough trouble with the throttle & the pitch mixed or allowing a governor to do the throttle duties. If radio manufacturers start splitting them up,,,,,,, I'll have to wait for stem cell research advancements to fly any more,,,,,,,, because I'll need one more hand & one more brain.

If God had meant for man to fly, he would have given him more money
