SR Microheli carbon fiber frame question

[RCpilot13B]

Hello guys and gals

I just got an SR from Fleabay and (this guy really duped me, but that's another story) and while centering the servo arms, I found that the travel on the servo on the R (Right side, tail facing you) hits the canopy mount. This isn't an issue on my SR with the plastic frame. Any one else have this frame and have the same experience? I am just wondering if I set a limit on this servo will it greatly affect the birds maneuverability?

First photo shows my servo in neutral position, the 2nd shows its travel limited by the canopy mount. I still have about another 1/16th of a turn on the servo tester dial before it hits its actual limit.

i have never seen one of those CF frames, i mean have seen em in the package but an SR assembled with it I hadn't....somethings not right there, are you sure the mount goes there? I guess really doesn't look like it mounts anywhere else....

You may find that those servos don't move as much as you think also. Also you could maybe notch the arm or use thinner ones...but that would be a task to find ones to fit those servos...

[RCpilot13B]

Yes, it goes there. There isnt anywhere else for the servos nor the anti-rotation bracket that is also the mount for the canopy brackets to go. Believe you-me, I am just as puzzled as you are on this.

i just added a thought there I guess after you posted...that arm may not get up there to hit it.

[RCpilot13B]

I've never seen an Eflite servo arm really thin, or as thin as it would need to be to not hit the canopy mount.

If I notched the arm, I'd be cutting it in half to get enough clearance, which is why I was wondering if I set an upper limit on the servo if it would greatly affect the way it flys.

[nighttrain06]

As I said, I am thinking that the servo arm may not get into that, because if you might have noticed on the stock SR the servo arm swings up close to that mount also, without interference. What I would do is set the heli up with your pitch ranges that you want, then test the cyclic to see how far it goes. I usually set my SR's up at a minimum 10/10 and have no issues with making contact with the mounts on a stock SR, which sets about the same position as that one.

thanks, I'll give that a shot

Oh I was thinking also what are your settings on swash mix? If they are 60/60/60 or more if you run into and issue of too much servo throw you can back that down a bit to stop it.
I had to lower alieron and pitch on mine to keep from smacking the slider on the top of the head, and arm hitting the canopy mount....

Hey RCpilot, a buddy of mine got ahold of me last night saw your posts, he has the CF frame also and says he has no issues with it hitting the canopy mount here is a couple pix of his set up you can compare....

I haven't set it up yet, I was just using my testing equipment to see the full throw of the arm, and saw that it hit the mount on the way to its peak. I will look into those settings. Also, those pics are in the neutral position, could your friend take a pic when its at its peak? I'd like to see where it stops when its all the way up on their frame.
Thanks

I'll see what I can do

Oh I forgot to add that when I set my heli's up I use that servo tester to test the movement and center the servo's also. And as you know the tester moves the servo's to their perspective end points, but they usually when bound and set up on the heli won't go to those stops that the tester moves them to.
I found an issue I was having with one of my SR's where I had it set 60/60/60 on the swash mix that the servo was in fact hitting the canopy mount and for some reason the receiver would then begin blinking, after it initialized and was solid. I discovered the arm was getting into the canopy mount when I moved the stick left and when it did the receiver began to blink. I lowered the Alieron setting from 60 down till it quit hitting and the receiver began staying solid. This also happened on my pitch, only the heli would continue to try and reinitialize until I lowered that setting also.

Ok here ya go he sent some pix of full throws...

I was looking for a CF frame for my SR that I was going to rebuild. Luckily, I could not find one since microheli was sold out and quit making them. I did notice a review of the CF frame on the microheli site saying that they had the same problem with the canopy mount being in the way.

I don't have a microheli frame but I would try rotating the servo arm down 1 click on the servo shaft and using the top ball mount on the servo arm.

[nighttrain06]

The swash mix normally sets up with 60/60/60 settings, I've had to lower that on 2 of the 3 SR's I have. Drop it down on pitch, and redo pitch setting
Can aliviate that issue.
