Flybar Paddle Weight
There are two pieces of metal rod in the flybar paddle. Which one should I keep or remove if I want the Evo50 or SDX to have much better cyclic response? Also, what is the trade off after the adjustment?

I have always removed the brass and left the lead . I guess it all depends on what you want .

Weights
All depends on how you fly, Slow and steady or in windy conditions leave the weights in.
If you fly 3D and want quick cyclic response, Try removing one or both.
That's the beauty of the stock paddles you can change them easily and experiment to find what works for you.
I fly my SDX with no weights and I use a Aligne 600 440mm flybar and it flips and rolls great.

I have bothe the SDX and the Evo50.

The SDX flies very nice with no weights, it just gets a lot quicker on the cyclic and there are no big cons with flying without weights.

The Evo 50 gets a bit pitchy with no weights, I tried it recently but I put the lead weight back.
Before I flew with only tha brass weight for a long time and it makes the evo really steady and 'straight' flight.

I'd suggest you start with the brass weight only, and it you need a quicker roll and flip, then change to only lead. If you still want more flip speed then try without weights but be prepared to loose the 'fly on rails' feeling.

NO weights, the SDX is insane. It is fast but I think it looses some of its tracking ablilty. (Thats just me, Dominik flys with Stubs and no weights so I don't know how crasy that would be.) I found that if you take the Brass out and leave the Lead in you will have rally fast cyclic but you wont be all over the place in your FFF manovers.MRC Host

On the Evo, I found that no weights was just too unstable but the roll rate was limited when running with either of the stock weights.

After a bit of experimentation, I found that adding just a bit of weight to the paddles maintains that "riding on rails" flight performance while giving maximum cyclic speed.

I think you'll see something similar with the SDX. The Hirobo paddles without weights are just a bit too pitchy to keep that tracking abilities that these helis are known for. Just add a bit of weight and you get that back, while keeping most of the cyclic speed.

I created custom weights by cutting down some old flybar material and inserting these into the position that the lead weight would normally occupy. My lead weights were 5.08g each. My custom weights are 3.48g (steel is less dense than lead). The only difficulty with this customization was that the inner end of the weight needs to be a smaller OD than the normal flybar to accomodate the cap. A few minutes with a dremel and cut-off wheel results in very nice custom weights that are a drop-in fit for the Hirobo paddles.

I actually suggested to MRC back then that Hirobo should offer steel weights around 3.5 grams. Guess that idea went on the discard pile.
