I just setup my servo tonight. I couldn't get one canopy mount off so I had to install servos with the bearing blocks on the frame. Once I had the servo's installed I got all the servo's moving in the right direction, with pitch/elev/aleron set. Then I removed each servo and set the arms to 90 degree. when installing the elev servo you will need to use the allen that came in the parts bag. also I had to use alot of sub trim with the ds410.

I also put together the tail sections and checked the tail for locktite. Make sure you check the tail blade grip bolts. mine didn't have any locktite.

You can use sub trim on the swash, is only on the tail that is not recommended, but the trick is to use different arm to try and get to 90, once you have them as close as possible then you use the sub trim.

I dont have a pro, but to me it looks like you should take the bearing block/servo mount, out of the frame, secure the servos to it, then mount it back in the frame.

That is what I do, I take a 4 way arm and twist and turn until one of the 4 sides makes 90 then cut of the remaining 3

I wouldnt think to check the tail for locktite since the frame had a ton of locktite on the allen bolts good tip, thanks
. I took the head block bolts out but couldnt get the top block out because the canopy holder studs stick out too far. How do you take the canopy all thread holders out? I guess i have to take all the bolts out of one side of the frame to get the blocks out, what a pain, why would it even come built!! lol, im lazy i guess. As far as the servo horns go, Align gives you arms that are only one arm, not four like the Hitec servos give you. |

You screw the two nuts on then tighten them together (lossen one/tighten the other) try to line them up..then turn them as a pair, they will usually grab on to the stud... |

Does the stud have a hole in the end for a hex key? The body mounts for the 250 are the same way but the studs are put it with a hex key.

Stud doesn't have the key hole.
Also from the Servo screw bag, there are two different size flat washers 6 for the cyclic machine screws and 4 for the tail screws.

Pull the servo blocks out to put the servos in.
The studs have a hex key hole. It's just in the bearing block side. Double nut to remove. Check everything for loctite. Nothing will break when you pull it apart like the 250. Add more grease in the thrust bearings too. Add glue to the tail pitch slider ball. |

Hi,
I am using DS520 for tail servo on 450pro. i couldnt center this servo like futaba tail servos, are you guys adding subtrim on rudder to center? or is it ok to center as much as you can and leave it? also the ball link on the tail pitch slider and ball link on tail servo horn doesnt line up, are you guys having the same issue? did you guys bend the tail control rod to move it freely? Please advise. Thanks |

The stud has a key hole according to the manual. Looking at the manual posted it clearly shows a hex hole in the description of the stud, maybe those damn align techs found a way to put them in backwards(wouldn't put it past them).

Ok, figured out the servo thing. What a huge pain in the butt!!
How are you guys routing your wiring and placing your electronics? Im going to try and put the esc under the battery tray and the receiver in the back mounted to the frame not the bottom tray. Any ideas? |
