DFC head on 700n

[tonystevens]

im finding to get 0 degrees im having to raise the swash and wind the ball links on the pitch links out to the point that theres not enough thread in the ball link. This is with the threaded rod tightened fully in the pitch links.
if i undo the threaded rods a few turns from the pitch links then i can wind the ball links back on with enough thread inside them. Do you think these threaded rods should be tightened down fully in the pitch links or are they ok to be left a few turns out?

i know one of the lads at the club took the dfc head off as he experianced the same problem that you are having,having the bolt threaded out a bit didnt seem right,well it was more than a bit to be fair to get it close to zero degrees,he didnt attempt to fly it,is this the same bolt that has been upgraded to make it stronger?

[tonystevens]

No thats the bolt that holds the pitch link to the pitch arm thats being upgraded.
Im talking about the threaded rod that goes between the ball link and the pitch link.
Ive put a washer behind it so i can atleast tighten it properly but i agree it doesnt seem right to leave it loose.

ok cheers tony,i know he had trouble with it,+18 deg -7 deg with everything as it should have been,to get it right there was some major messing around with both the now upgraded bolt and the linkage rod,it just wasnt right....i dont know the outcome....not alot of help i know

cheers

So has any one else had this problem?

[squareben]

I had mine setup ok but i am using the 700e elevator A arm on my nitro. This is shorter, so seemed to put it in the right place with everything tight.

I know where you are coming from Tony had the same problem, I did not like the threads not being tight on the push rods too the grips, PM Minty on talkheli and ask him how he set his up and let us know please...........

A shorter A arm would make things worse, ive had to higher the swash as it is.

[sacko]

The A arm isnt shorter, just increases the servo resolution.

Saw this on HF, maybe able to see what he has done?

yes it was v-bar

[stanley1]

dont you need the shorter main shaft to enable the swash to sit higher, then the rods could be tight? maybe im wrong

[squareben]

Yeah sorry i forgot the 700e A arm is only different on the horizontal part. Won't make any difference on the pitch at midstick.

Comes with the head

[squareben]

By the way has anybody got the new parts yet? I spoke to Bob at Skyline and he was expecting them to arrive anyday.

Are you all grounded, or are you flying anyway?
