Jeff is your plan to maiden the plane this weekend. Love to see it fly.

Joe,

Hoping Friday or Sat. morning at LAMA. It just depends on the progress I make with the build and weather. I will keep you posted.

-Jeff

Time to install pushrod connectors onto the servo arms, and thread the ball links onto the pushrods.

This is a set-up I have used on -6- different 3DHS planes, and it has proven to be solid, accurate and reliable. Not a single failure.

Note: You will notice the pushrod connector nuts have two different sides. Make sure the side with the small but pronounced countersink is exposed.

Double Note: Notice the elevator pushrod has a carbon fiber tube for reinforcement. Nice touch!!


-Jeff

Time to attach your pushrods to the control horns.

Make sure to install the washer on the ball-link side for added safety.

-Jeff

Time to attach the servo extensions. The elevator servo gets an 18", and the ailerons get 6" extensions.

I have seen many methods of securing the servo wires to the extensions.
-Clips
-Safety Wire (Credit: Scott Stoops)
-Tape
-EVEN GLUE (WHY? I'm not sure)

I personally like to use 3/8" shrink tube to hold the connectors in place. Works well for securing the "semi-permanent" connections. Shrink tube is also very easy to remove with a razon blade when the time comes. I then like to use safety clips for all other connections.

Looking good Jeff. Looks like we might 3-4 of these at Lama on saturday!

Thanks Cory.

I will have to be sure and bring my camera! See you there...

I have to remove the wings every time on this size plane and don't like to plug into the RX every time so I us a short extra extension if needed. the Hitec 225MG servo leads just make it inside of the fuse (if I don't twist them like I prefer to do). Is there enough length to comfortably use the 6" extensions permanently on the RX?

I use (2) 4" extensions on each wing. One attached securely to the servo like above and one plugged into the Rx with a zip tie holding it on the correct side of the fuse so it is easy to tell which extension goes into which wing.

Not that it matters in this size plane but I usually take the cover off the male plug when I am going to secure a connection with heat shrink like this. It is kind of a trade off for the weight of the heat shrink but where it has come in handy is the connection will be smaller which I have been able to pull threw some tight places. You can also use a smaller size heat shrink tube

Approximately 1" of HS-225 servo lead extends through the wing root into the fuse (including the connector, ~1.5").

Yes, do-able (though perhaps a bit UNcomfortable) to mate with extensions permanently plugged into the RX.

I would consider 4" or 6" extensions from the receiver and safety clips.

Like these: http://aero-works.net/store/detail.aspx?ID=305

Not enough weight penalty to worry about on this size of airplane.

Good idea Rob, thanks!

Time to install some servos.

I like to drill pilot holes for the servo mounting screws using a 1/16" drill bit. Then run a screw in and then back out of the hole and harden the hole using thin CA. I do this on every airplane, regardless of size. A little peace of mind...

-Jeff

Jeff,
The build is looking great. Hope to see it fly Saturday at LAMA.

Hypersprint,
Good idea on zip tying the extensions for the ailerons to the side they are supposed to go to.

I have used the heat shrink method of holding extentions together but have melted a couple of plastic cases myself. The aeroworks servo locks are very nice especially for places that need to be removed. I have used for semipermanent locks the smallest zip ties I can find. They work great by looping through one of the inside sets of 3 wires on the extension to the servo wire..
