The one that is the same size is the stock Pantera one, or you could order one from MA, they have a ton of various lengths.

Not to be ignorant, but what is a Pantera?

It's the new 50 from Audacity. Go into their forum, and you'll find a bunch of threads on it.

There's a few stores, but it's mainly direct. If you are looking for a flybar for the conversion, it's probably easiest to get one from Miniature. Just about every shop stocks their parts.

If you are looking for one that is the same length as stock, this is pretty close, the stock is 390mm, this is 425mm, so your cyclics would be a little quicker, and it would be a little more stable in a hover.

I think this is the 520mm Predator one I have been using on my Pantera (same length as the Raptor 60, may be easier to get that one locally), and now on the Evo:

Cool, I think this is a great idea, I've been tossing it around in my head a bit lately. As a matter of fact this weekend I put some QUK flybar stiffners on my Evo 50. I have been told there are dangers in doing that but I sure do like em!

It would be interesting to know what the effect of going to the 4mm flybar would be with everything else in the original stock Hirobo configuration....same flybar length, stock paddles.
I'm always banging the cr@p out of my helis moving them and the flybar usually takes a beating. Going from 3mm to 4mm sure would beef it up.

I know the Synergy is not a good benckmark for the EVO50 but I wonder if Jason and Todd tested both 4mm & 5mm flybars before they settled on the 5mm flybar? Probably the testing concluded with it not being of significant consequesces to step up the additional 1mm. Otherwise the Synergy would have a 4mm flybar like all other 90's.

If I had a way to tap the stock paddles so they'd work on the 4mm, I'd tell you how it works with it like that. But alas, no 4mm tap.

I'm willing to bet that maybe 2-3 people out of all those on RR could notice the difference in performance, if there is one. We all get too caught up on saving a gram here and there, when in reality none of us is good enough to notice the difference. I don't have a gram scale here, but I will get an exact weight difference between the stock flybar and the 4mm one that is almost exactly the same length. I'm betting that the difference is minuscule, plus it is distributed along the whole length of the flybar, and weight towards the center won't effect the flying characteristics.

Make no mistake, this is not a performance mod. It doesn't change the performance one way or another beyond giving you more options. It makes the heli easier to live with, and cuts down on those times you get out to the field and find you tweaked the flybar. If you hit something hard enough to tweak a 4mm, you will have hit pretty hard, and will know it.

I would venture to guess a thicker flybar is a stiffer flybar is a change in performance.

going from 4mm to 5mm adds alot more mass than going from 3mm to 4mm. I fly with a 4mm ss flybar on one of my evo 50's and stock on the other. same paddles(stock with no weights) and I can honestly say the stiffer 4mm flybar makes for faster cyclics.

There is a 78% increase in mass between the 3mm and 4mm of the same length.

from 3mm to 4mm you gain 5.5 cubic mm in the cross section. 4mm too 5mm you gain 7 cubic mm in the cross section. almost 1.5 times the gan from 3 to 4mm

3-4mm is less than an ounce difference in weight overall. I don't think it's enough to be of concern.

The 4-5 difference would be related to a larger 90 size ship. Also would not be a huge difference relative to the overall weight of the ship.

I'm sure any undesireables can be tuned out with different length flybars and/or different paddles.

changing the length enough to compensate for the weight difference would change the way the head reacts much more than the added mass of the thicker flybar.

Just finished doing this to mine tonight...went with a stock length flybar (from HeliProz...Mavrikk 4mm SS flybar part #805635), Radix Stubz (set quite a ways out), and while I was in there I added the SD-G seesaw and mixing arms then set them for maximum mobility. Can't wait to fly it, it should be interesting.

I just converted one of mine.

I used an Ergo JRP9830081 flybar (450 mm)

Instead of using spacers with the seesaw bearings I took the flybar carrier apart and took a little material off the inside ends, equally on both sides. This shortens the distance.

Thanks for the post Nick!
