Going between 2x the thrust needed and zero, the average thrust will stay the same (= stay in hover) but the control authority will double (4x when at double the throttle, /2 for average = 2)

No, its not efficient and not everyone does it but there *IS* a benefit.
With years of experience doing hovers, I have to disagree. I find it just as easy to stop my planes from torque rolling with constant throttle as I do with blipping. If there is a difference, Iíd say itís marginal at best.

I also donít really have an issue executing point roll harriers with less frequent throttle inputs. Thatís just me though...

Two things I really hate to watch and listen to is throttle pumping /pulsing and guys walking around after their model when hovering /torque rolling.

Yes throttle pulsing can help on occasion but 98% of the time if you are on your game you can do most of it with smooth throttle inputs.

For the most part, for 3D maneuvers such as upright/inverted harriers, hovers, etc. a constant throttle input is very much achievable. For other 3D maneuvers like high alpha 4-point rolls switching directions, vortex, knife edge walls, flip turns, waterfalls, etc. I have always found that throttle variations are helpful to accomplish crisp stopping on the desired point and keeping the same altitude throughout the maneuver. Giving a burst of throttle during high alpha point rolls can help keep altitude and stop rotation. Otherwise, it could get very 'mushy' and the points will look blended together rather than separated into points.

Kyle putting us all to shame with his butter smooth throttle inputs:

Note, he can counter-torque roll an airplane mid mover without much movement of the throttle (which includes a 4 point counter torque roll).

I think this is a great example from Tavis of throttle variation but without big throttle pulsing other then the motor warm up . Flying starts 45 seconds in.

I absolutely love watching Kyle and Tavis fly. Outstanding...

Thank you thank you! Itís 100% possible to be smooth without slamming the throttle back and forth. Guys have been doing it for years. Even through maneuvers like 4 point Harrier and hover rolls. Why itís still trying to be justified is beyond me..

That was like watching paint dry... another Yak just floating around... when Jase does a Rifle Roll at 100mph 6 inches off the ground and then reverses it mid stride shoots the thing up in the sky down to a knife edge spin to a water fall into a torque roll faster then you can blink.. thats a bad dude!! Im not saying this guy isnt good and i appreciate how smooth he is but this topic is so retarded and whether you blip the throttle dont blip the throttle.... WHO CARES... your really gonna take the time to post vids and i told you so's... come on guys its a hobby.. just remember that at the end of the day!! Ok im done you guys can hang me now!!

I sure would like to see Kyle's throttle geometry set up and his throttle curve!

Kyle has flown many of my planes at Joe Nall, and other places.
He generally takes all expo down to almost nothing, and flies 3D only on high rates. Throttle has no curve.
Truly an alien!

Daniel Holman was another one flying with little to no expo.

Okay, good to know. I would then assume he likes a true linear mechanical set up on the servo arm, (servo centered at 1/2 throttle at the carb) no offsets?

None of what you said was relevant to the topic, but okay.. Do you have any clue who Kyle is anyway? The point of that video was to prove that you can fly 3D very smoothly and with plenty of control at a constant throttle. It wasnít to compare whoís better than who and turn into a measuring contest glorifying the most popular face on the RC world. Try to stay on topic.

The throttle blipping is obnoxious, thatís why we care. Itís annoying to go to an event like Joe Nall and hear engines changing RPM several times a second for hours on end.

Kyle has a habit of taking someones airplane he's never flown before and making it look like he's flown it a thousand times. Doesn't matter throttle, expo, or rates, he can make it dance with ease.
