Servo Saver Mod

[Jetman71]

I have fitted the Lynx Heli micro servo arms to my 180CFX. However the tail servo arm seems to be a bit long once it is sat in a position. Should / does it need trimming down?v The arm appears to touch the frame when in the up position.

Not sure the answer to your question. I've crashed my 180 a fair few times, I have the diy servo saver mod on the cyclics but nothing on the tail and never had a problem. I would just put the stock arm back on the tail

[Jetman71]

OK thanks for the reply. Will put the stock arm back on for the time being. Is it worth doing the servo saver mod as an alternative on the stock arm?

as above I've never stripped the gears on the tail BUT I lave now replaced the tail servo for a Spektrum servo after a slight tail wobble issue & now flys much better

Which spectrum servo? The 3060?

i have the diy servo saver mod and did the tail servo also. Not stripped any gears after a few crashes all is good on the servo gears. The servo horn/ arm on the stock tail servo 76t has been cut short also. So not an issue.

yes Spektrum H3060 on the tail , had to modify the frame slightly but well worth the effort

What's the specs compared to the stock tail? I am finding the stock tail servo a little slow. Did you have to adjust any of the PID settings with a different servo than stock?

I don't know if it's any faster but you can look up the specs on the internet, it is a straight swap apart from a slight mod on the frame
Here's a link to a thread on helifreak about the mod

Finally got the H3060 tail servo installed (pictures) - HeliFreak

Yes I have read the mod thread for the 3060 tail servo. Looks like a good choice. I will look up the specs then and see if it's faster than the eflite one

[Bhujang]

So I can't find the specs for the h3060 but the 76t looks fast! Says 0.03s/ 60° at 4.8v may have to strip the tail and have a look as maybe I got binding. The eflite should be way fast enough.

Here is the specs

Ahhh found the specs for the h3060 it's 0.06 slower than the eflite 76t...

You must be faster at typing then me

I've never found the tail to slow for me , there may well be something not quite rite in the servo or tail mechanism

[Bhujang]

I think that the pitch slider is catching at one end. Not easy to adjust the end points of the tail on this model. Also do you know or have a link helping with the PID gains?
