View Full Version : Flybar & Paddle Combination for AP?

I installed my mount and camera the other day and am quite impressed by the additional stability added by the undercarriage weight. However, I am looking at changing out the the flybar and/or paddles to possibly further increase stability. "If it's not broken, why fix it" comes to mind. But just the same, I figured if change can improve then move forward. Having read a few posts, what states is short and to the point:

Shorter flybar, more stable, less agile. Longer flybar, more agile, less stable.
Heavier paddles, more stable, less agile. Lighter (3D) paddles, more agile, less stable.

Given that my L10 will be AP dedicated, should I:

A. Shorten the flybar to the 300mm or 360mm and keep the stock 2359 light-weight flybar paddles (16 gms).
B. Keep the stock 400mm flybar and change out the flybar paddles to the heavier 2358 Stabilizer Paddle (26 gms).
C. Change out both and add the heavier 2358 paddles as well as the 300 or 360mm flybar.

It may be a fact that I will have to play around with the combinations. But I figured someone out there will have tried and tested and found a reasonable balance between the flybar and paddles for optimum stability. A little input from the experienced AP'ers would be much appreciated.

I use stock flybar, raptor 30 paddles (black 30 grams) and KSJ flybar weights.

Hey DJ...thanks for chiming in. I was actually thinking about flybar weights, but thought that might be overkill. Interesting to see that you are using them.

Is there any particular reason why you decided to go with the stock 400mm flybar and just increase the weight with paddles and weights?

I stretched my Logo 10 to run 550's. Figured with longer blades it'd be best to keep the stock flybar but add weights.

That makes sense on the 550 stretch. I will stick with the 500's for now, but I most likely will stetch at some juncture.

Gave it some thought, and unless advised otherwise I will try the following steps:

1. Leave 400mm flybar and add 2358 Stabilizer Paddles.
2. If not enough, shorten flybar to 360mm.
3. Thereafter add flybar weights.
4. Lastly reduce HS from 1890 to required rpm.

I hopefully won't feel the need to go as far as adding the weights on 500 rotors or reducing the HS. That is, unless 1890 is considered a little too fast for AP but it seems go to go at this point. Will see what happens. :)

nope... not too fast for a heli this size. My 550 Logo 10 spins at about 1950

Thanks again DJ. I certainly appreciate your professional opinion.
