Want fast cyclic responce for my Freya w/ FFZ-3 rotor head. Will be running RotorTech 710 main blades with RotorTech 95 tail blades at a head speed of 1850RPM.

Choices:

RotorTech 3D 19g 117mm
RJX Hobby 18g 85x55
EDGE 17g 93x60mm
SWE 15g 105x53-45mm

Anyone with flight experience with any of these paddles?

I only need one!

You'll get faster cyclic with the 690 blades. 710's get you better auto performance but at the cost of cyclic and tail rotor interference. Be sure to run 95's on the tail if you are using the 710's or you will end up taking a chunk out of your main or tail blades.

You can also use the 555mm flybar to increase cyclic rate. Be sure you get full swashplate travel without binding.

The stock paddles will do everything you want - just pull the weight or weights out.

Lastly, be sure you are using the correct (high mobility) hole in the flybar carrier.

You can also adjust your flybar feedback ration on the bell-hiller mixing arms to alter the flybar input to the head. Don't use the outermost hold (nearest the yoke), use the next one in.

Quickest mix ratio: https://rc.runryder.com/rr/rrpw.htm?p=3516841&i=1

If unclear, please ask questions.

I am going to go with the quickest mix ratio you have posted a photo of. My question now is which of the paddles above would be best for that ratio or am I not going to see a difference from the stock paddles with all the weights removed. I was think of either the RotorTech which is a large surface area paddle or the SWE paddle which is the lightest. Any opinion on this matter.

Also on the photo of the fastest mix option. My only question is which hole to mount the mixing arm on the seesaw. The one side has one option and the other has an outer and inner option.

The see saw has two hole options on one side. The closer hole to the center of the head is the closest of the three and creates the lowest flybar ratio when coupled with the mixer set up from the picture.

Before you move the mixer, I would fly the head with the mix ratio in the picture. Fly the paddles you have without weights as well. Paddle choice is very personal. The paddle that gives you the quickest cyclic may also track poorly or be too pitchy. I know the RT paddles are quite fast. I'll let other guys comment on the other choices you listed.

The reason for these two suggestions is that in the quest for quicker control response, you can destabilize the rotor system to the point that the model is no longer enjoyable to fly. Fast rates are nice, but if the model becomes too pitchy or no longer tracks well, it becomes a PITA to fly. Proceed incrementally with your changes rather than going for the lowest possible flybar ratio from the start.

I have my Freya on the "high mobility" mix setting per the manual and the stock paddles with no weights in them, with the 555mm flybar. Cyclic speed is quite good, but you also have to be realistic, as this isn't a ridiculously-overpowered 500 sized electric.

The other thing that really made the cyclic crisper is the delrin head dampeners from CarbonXtreme, although I don't know if those exist anymore. They do detract from hovering stability somewhat, and you get a slight bobble with small cyclic inputs.

Also, be sure to quantify what "faster cyclic" is to you. Do you want the initial response to a stick input to be faster, or do you want higher steady-state roll/pitch rates?

I am looking for faster roll/pitch rates not stick input speed.

I am going to run 690s the black Hirobo dampers with stock paddles and no weights with the mix setting in the photo Dr. Ben posted above.

Make sure your cyclic deflection is maxed out without binding, and use a cyclic ring on your transmitter. The roll/pitch rates should be pretty fast with that setup and maximum cyclic deflection.
