Status: offline 		I picked up some Futaba 3114 servos for my HBK2. Thought I read on one of the forums here
that they were replacements for the Esky stock servos.
Anway the 3114 are smaller & the top & bottom screw holes, both won't screw in to mount.
Just one of the screws will mount. Is there a servo adapter, or do I just plain have the wrong
size servo? If so, what ones do I need?
By the way. How are the Esky digital servos? Any good? Junk?

Status: offline 		hi high...i get a lot of credit card offers in the mail...capital one or amex send clear plastic ones...i save them to use for scab repairs on frames, canopies, etc...ca, goop, or jb kwik and a little piece of credit card makes strong repairs/reinforcement...if the servo is not tall enough, maybe you can build it up and drill a hole where you need it...i use oem esky servos in my everyday hbk2...they're ok...btw, i'm using hitec hs-45 servos in my cf frame...fits perfectly...here's a pic...ken

Status: offline 		Thanks Ken. I like the idea of the HS-45's. Got the 3114's at my LHS.
He will trade the 3114's for me I'm sure. Good pics! Thanks!

Status: offline 		I've purchased 7.4v 900mah batteries from dealextreme several times.
So how do the Tower Pro servos stack up, say against the HS-55. I'm
thinking of doing the HS-45's.

links on the servos?

Status: offline 		Ken, thanks for pointing out the linkage sets. I traded my 3114's in for the HS-45's.
The HS-45's do drop right in & they have karbonite gears. All for a $2 cost difference
per servo.

Mr. Ken,

I will buy a set from you when you figure that out. Ever since I saw the Guai linkage you posted months ago, I have tried to "make" my own with little to no success....I keep over-bending metal and breaking the plastic inner threads...

Keep us in the loop! Hehe

Status: offline 		The HS-65 is a drop in for the stock esky servos and its pretty easy to put ball links on it. Its fast, very strong, with Karbonite gears. As its for the cyclic It is ok as far as direction of rotation but if your running your stock radio you can and cant do it. Your stock radio has a provision for changing the servo directiion however it has no provision for changing the Swash mix settings which have to be moved down to about 20% when you go to the ball links. I guess you could make up some new Z bend links and get around that.
I spent a lot of time centering and adjusting my HS-65 with my subtrim to get them to move in perfect unison throughout their neccessary range which is not very much actually.
Trading the 3114 for the HS-45? is that a step in the right direction as the HS-45 is only about a 13 oz servo at 5 volt and relativly slower at .14 sec as the 3114 is a .10 sec servo with over 18 oz of torque. With those figures your faster stronger servo is a stock Esky compared to the HS-45. You could have went to the HS-65 for about 20$ each on Ebay.

Status: offline 		Are you still trying to make those little "hoop" links?
Why not give that up and just use ones like I made?
Ignore the blade holder and just hook up a stright rod.
I think I should refine them a little more though so they dont look so "prototype"

Did you have those on your Helicopter when i saw it? If so, I do not remember them . I really like the look of the Gaui linkage. i am shooting for something with a nice streamline-type look to it to hug the blade grips and of course, work well. Where are the pics. of your "prototypes"?

Status: offline 		I dont remember if they were on or not, I dont think I had them installed as you were asking about bending that spring steel rod and I remember saying something about if you went that route you would probably need to heat treat the linkage after you softened it to bend it. I "lost" them when I put back on the plastic washout (nowhere to put the ball joints). Never saw a Gaui linkage up close.
If I get time tonight I will put back on a cnc washout and take a picture so you can see how they were set up.
