Can you guys suggest some good cyclic servos to use in this beast?

Shop says will sell me 3 9252's @ 70/ea, but is that a little overkill?

That depends on what type of flying you want to do etc.

I use the 9252's in all my 600 size and larger helis (nitro and electric) as I really push them hard.

For just sport flying a lesser digital may do the job, but make sure the output shafts are supported by TWO bearings and not just one.

Well I dont do that yet, but for what the bird costs I decided not to skimp on the servos so I went with the 9252's on the cyclic and a 9254 on the tail. I worked on her for 2.5 - 3 hours yesterday and this is where I've got so far:

That rotor head looks awesome ! You will never regret buying those servos. I too use them on most of my helis.

I keep telling myself that too LOL - well no building yesterday, I hope to get something done today....

I know it doesnt look like much, took me all day (with interuptions) but this is what I got done today.

How did ya'll mount the elevator servo? seems the plastic backing that you screw it to is being blocked by the post. Did you dremel a groove in the plastic to fit around the metal post?

can take pic if needed.

On all my other helis when you tighten one end the other end will spin requiring 2 allens to tighten it. This one the shaft is TIGHT (doesnt spin) I tighten down one side as tight as can be then the other no spinning, is that right? I'm even taking it apart and having a hard time removing the shaft it doesnt want to budge, HELP.

LockMD,

Send me a pm or email. I can help you get that swift dialed in.

2 concerns.....the gap between the gears and the swash doesnt have much room to move up/down on the shaft (manual page 7) says short (hole to end) goes to the head. Finless' video for the swift 16 says opposite but since this is a different animal I followed the manul. Should the short (hole to end) go at the bottom? Here are some pics:

I thought the Swift 620 used 3 main gears, or was capable. Looking good though, cant wait until I fly my 550 carbon :D .

The manual shows it with 3 installed but that is for HV setup like a 10S or 12S setup, I'm only going to do 6S, so I guess the gap is okay only using 2 gears :confused:

Yes, I would have thought so. I dont see the point in 3 gears, more friction = more power drain.

See how you get on with 2 :) .

I think 9650's are the way to go. I was running DS821s on mine for sport flying and that's fine but now I'm much more agressive. I have a 9254 on the tail and that has worked great so far.
By the way, did you resolve your main gear issue? The main gear in the pic is actually the WRONG gear, it's for the 550 not the 620. The 620 uses a "double stack" gear (it's just twice as thick as the lower gear).

I'm running the full metal head on my 550 Carbon (same head as the 620) and I had to cut almost 1/8" off of the washout guides to allow for swash clearance (on cyclic - pitch movements). Once done, there is no binding on mixed inputs....flips and rolls nice!

I ran the 9252 servos in my 620se before i sold it on ebay and it flew awesome.
I moved those over to my 550 carbon and they work great in it as well. The only problem with thw 9252 servos is that i dont think they can be ran at 6V. (there are lots of threads about this) I ran myne at 5V but it would be nice to do a 6V setup.

Also, the gear in the picture is NOT the wrong gear, i used that exact setup runing an 8S setup with no problems. As stated above you only need to do the 3 gears with real high power setups.

Correct me if i'm wrong but isnt the S9650 a micro servo, making it too small for the 550 carbon?

Before I buy i'm going to wait to see how I get along with the DS821's.

I have 821's on my ES600 seems okay but I've been reading some bad stories about them. For the 620 - I went all out 9252's on the cyclic and 9254 on the tail.

Edit: Agreed, I would not put a 9650 on this beast.

"Tecmaster" That's really odd. So no one is running the "double" on the main? The gear I'm talking about is the one that comes with the kit.....it's one gear but double thick (so that you can run the longer pinions from Century). It also eliminates the need for the two hubs.
While running three gears may work, it's unnecessary, especially running higher voltages (i.e. 8s), just use the double, not only is that Century's preferred setup, it's even cheaper than running three.

Huh :confused:

If you look at my pic with 2 gears that is what came with my kit no double thick gear came with mine......manual says the 3rd (optional) gear is for 10S+ systems and was not in the kit.

I'm not sure if this is what you have but....aren't these two different? The CNE610AHD is the one I'm referring to...

Once again, I guess the replacement parts are not what you get in the kit. The kit does not come with that double gear, but when you strip yours I gues then you'll have to go that route :confused:

this is how the kit comes:
