Build Log
Speed 2.0M from F3x.com

Now that I have my Speed 2.0M done, I thought I would put together a build thread for other to follow, if you see anything I missed let me know

Step 1: Layout plane parts and gather building materials

I would HIGHLY recommend that you purchase servos, battery and wiring harness from F3X.com when you purchase the kit

You will need the following materials:
7 Channel receiver (Berg 7 or AR6000)
Battery Pack
4ea HS125MG thin wing servos or equivalent
2ea HS65HB mighty feather servo or equivalent
2ea 24” servo extensions
2ea 36” servo extensions
2ea 4-pin deans connectors
4ea. 2-56 partially threaded rods
4 Heavy Duty clasp
Ballast kit (not necessary)
Plywood for servo tray
5 Minute epoxy
Micro Balloons
CA Medium
Canopy Glue
Lead shot

Step 2: Wing preparation

a. Fit HS125MG’s into wing, you will need to remove the label on one side, the servo closer to wing tip you may need to remove both labels
b. It is necessary to remove mounting tab on sero (See Picture)
b. Pre-drill holes for control horns (Provided with kit), be VERY careful not to drill thru wing
c. create opening on top of wing for flap linkage
d. Verify orientation and position of servos (DO NOT GLUE)

Step 3: Tail Assembly

a. locate ball linkage that is supplied with kit
b. Cut linkage so that when install into tail surface linkage rod are same length and clear of the bottom of the fuselage
c. Place tail surfaces in place, they should fit snuggly ( On the V-tail there are NO bolts, tape will be used to attached tail to fuse)

Step 4: Wire harness

a. Lay wings out next to fuse with servos setting on the wings.
b. Connect servos and extensions
c. Mark extensions approx 3 inch past end of wing next to the fuselage, this where the wires will be cut…
d. You will notice there are 6 wires and only a 4-pin deans, the black wires will be soldered together, same with the red, the remaining 2 white or yellow wires will each be assigned to a pin
e. It is a good idea to use heat shrink tubing on the terminals, but also around the group of wires to make it easier for wires to be pushed and pulled from wing
f. Remaining extension pieces will be installed in the fuselage, you may want to shorten the wires to reduce excess wire, additionally IF a Y-harness is to be used, you may choose to further shorten the flap extensions.
g. To determine extension lengths, it is a good idea to place the ballast tube and servos in place to get an idea of how long these wires need to be (see fuselage setup for placement)
h. Test harness PRIOR to installation, it is not uncommon that solder connections fail

Step 5: Wire harness installation into Fuselage

a. Install wings onto fuselage
b. Note that the wings have a hole on the surface that meets the fuselage for the extension wires to pass thru
c. It is necessary to mark the fuselage where the wing hole lines up, so that when the deans connectors are attached, they will be able to slide inside the wing
d. Make sure that the hole you create in the fuselage is only slightly larger than the deans connector.
e. Slide connector thru hole from the inside, then use CA to attach
f. Once CA dries, install wings again, you will need to enlarge the hole in the wing, so that the wing will slide tightly against the fuselage…do NOT oversize the hole

Step 6: Ballast tube setup

a. Now is a good time to feed a string thru the fuselage to the tail, to make it easier to run the antenna later
b. Locate ballast tube, the CG should be marked on the tube.
c. Temporarily position ballast tube so that the CG is 85-90mm behind the leading edge of the wing
d. Create a block that will sit on the inside bottom of fuselage
e. Create an additional block with a slight taper on the top and routed to match contour of tube.
f. With ballast tube in place slide blocks into place, assembly should be snug, if not make blocks taller
g. Since the ballast tube is located so far back, it is a good idea to attach something to the cover that is flexible and extend past the front edge of the cover,
h. I trimmed a strip 3/16 wide off the ballast tube cover with several passes of a very sharp knife
i. Then I attached this strip to the top of the cover with epoxy, set cover aside
j. Lightly sand inside of fuse and bottom of ballast tube where epoxy is to be applied
k. You are now ready to install the ballast tube
l. Use 5 min epoxy and micro balloons, make sure tail linkage is above the tube
m. Be careful not to apply epoxy in area of cover or it will be difficult to install the cover

Step 7: Servo Tray

a. Create servo tray out of ply, as in illustration 1 or from balsa stock as in image 2….either way works….I choose to use ply, since it seem to give me more clearance to the servo arms
b. Sand inside of fuselage where epoxy is to be applied
c. Make sure wires of the harness are at the bottom of the fuselage
d. Use 5 min epoxy and micro balloons, make sure tail linkage is above the servos

Step 8: Canopy

a. Find the canopy and a piece of carbon fiber tubing
b. Cut tubing so that it is approx ¼” longer than the canopy
c. Sand tubing and inside of canopy where epoxy is to be installed
d. Use 5 min epoxy and micro balloons

Step 9: Wing servo covers

I am going to use Tom's pictures here from the Nemesis build...

Normally this process would be done after the servos are installed, but there is very limited amount of adjustment in the covers and if the servo is off even slightly the covers will not work....so follow these instructions to trim the covers, but DO NOT GLUE

a. apply masking tape to wing (See Picture)
b. mark the joggle line to the tape
c. transfer marks from corner to covers
d. trim covers with sissors and sanding block
e. Set covers aside, DO NOT GLUE until servos are installed

this same process can be used for all 4 servo covers and the flap linkage covers on the top of the wing

Step 10: Wing servo setup

a. Prepare linkage by attaching heavy duty link to end of 2-56 threaded rod
b. center servo using transmitter and Reciever
c. install servo control arms, note: ailerons should be perpendicular to wing surface, flaps should forward 30-45 deg (see picture) to achieve full range of motion
d. trim control arms as needed
e. install control arms onto servos (It is difficult to install arms and retainer screw after the servo is installed)
f. place servo in wing (DO NOT GLUE)
g. use covers as guide to right-left placement of servos, arm should allign with link on control surface,
h. mark servo location
i. remove servo, and mix 5 min epoxy and micro balloons, be careful apply epoxy so that it is NOT near control arm
j. Using canopy glue servo covers can now be attached, use tape to hold covers on while drying (Allow glue to dry for 24hr)

Step 11: Radio setup

there are several radio setups that you may want to consider using, such as Differential, Crow, Snap Flaps, full wing ailerons

Careful the wing surfaces do not bind.

Wing surface may need to be trimmed at flap to insure linkage doesn't bind

a. Now temporarily install your receiver, you will need to remove when you balance the plane
b. neutralize the control surfaces
c. program the desired functions

Step 12: Preflight setup

Last but not least....you need to verify the CG, it is helpful to have an additional set of hands to do this

a. apply masking tape to bottom of wing, mark CG 85-90mm behind leeading edge
b. use masking tape, suspend mixing cup from nose (See picture)
c. add lead shot to nose until CG is between 85-90mm
d. mix 5min epoxy and lead shot then spoon into nose of fuselage.....make sure mixture is in nose and NOT on sides of fuselage or you may have difficulty installing the battery
e. now do your final installation of gear
f. range check your plane per receiver/transmitter specs
g. GO FLY!!!

Is tape really enough to hold on the tail?

You got a better way??

The V-tail pieces are pretty snug fitting, there aren't any screws to hold it on....

I used a piece of packaging tape and it seem to work fine

PS - I liked your last avatar better

(One piece V-tails)
I'd glue the tail on with epoxy if it doesn't bolt on.
A light glass strip wrapped around the fuse and up onto the inderside of the v-tail would also be good insurance, and nearly invisible...(One piece V-tails)

For the two-piece plug in type tails, the carbon rod supports them well enough, you just need to hold them from sliding with tape...

That being said,
If the tail ever comes loose in flight, it's OVER!
