Three taps connectors for balancing the pack
One of the round feet was missing so I used a piece of rubber that was the same thickness as the round feet.
The V-tail is removable.
Quick connector. The other male connector on the fuse side is also provide.
Showing a small ding in the wing skin.
Showing two different colors on the servo covers.
Showing the repair in the wing skin on the leading edge.
Fred about to launch.
Fred preping with Trevor as the timer.
Shot of Fred and Trevor.
Aileron servo cover installed.
One thing I did different from the instructions was to mount the servos on the bottom of the V-tails instead of the top. The only reason was because I think it looks better to not see them when its on the ground.
V-tail servos installed with same method mentioned for the ailerons and flaps.
V-tails with the servo covers.
I routed the V-tail servo extensions so that they rout through pre-drilled holes in the tailboom.
Flap servo installe with the modified linkage.
Aileron servo installed with the modified linkage. To install the servos I first put heat shrink on them so that they will be easier to remove if I need to replace them. Then I used goop to glue them in.
Wing with the supplier carbon fiber servo cover taped in place.
Complete linkage is slop free.
Showing control horn screwed into the socket and an uncut control horn socket. I used the Johnson Wax on the threads of the control horn when I epoxied the socket in with 5-minute epoxy to prevent the epoxy from getting on the threads.
The bottom linkage is the stock linkage and hardware. I decided to use a z-bend on the servo side so I made the top linkage from hardware I already had.
Then I fitted the whole wing togther to test the wiring harness. Everything worked. :)
I test fit the wing to the center panel and you can see how the servo connectors slid into the wing. I did not push the wing fully together in the pic.
This is the rx side of the MPI connector. You can see all the leads ready to plug into the rx. For the 6 pin connector I joined all the red wires and all the black wires and soldered them to the outside pins. Then the 4 center pins get the individual serv
For the flap servos I offset the control arm since the I will only use them in one direction.
I trimmed all the servo extension cables and soldered them to an MPI 6 pin connector.
Airframe fitted togther for preview the final product
looking into the main fuse
holes in tailboom for V-tail
carbon joiner rod
Center panel kevlar/carbon D-box leading edge
I chose the typical high contrast color scheme for the top.
Overhead of view of new layout for aileron servo and linkage.
V-tail installed to the fuse with 30 minute epoxy.
Bottom of the wing covered in Monokote.
Servo installed and torque rod connectors installed.
V-tail linkage epoxied in place.
Elevators surfaces cut free.
Finished product with caps trimmed flush with the wing skin.
Torque rods epoxied in place with balsa caps.
Torque rods in place to check fit.
Elevator and stab mounted.
Control horn on the elevator surface. You can not really tell from this pic but it is off center.
90 degree bend in the control rod
Wing weighs 2.1 oz.
The wing cap epoxied on waiting to cure.
Sneak peak at the final assembly.
Wing sanded slightly so that the fuse-wing interface is flush. Flash looks wild on the translucent red fuse.
Checked the angle vertically with a square.
Drew out 110 degree angle to use as a guide for assembling the V-tail.
V-tail cut in half.
Squeeging the resin over the cloth.
Cloth after most of the resin has been squeegeed out.
Glass cloth ready for the resin
Showing the battery sticking out of the fuse.
Hard to see what is going on since the battery is reflecting in the wing from this angle.
This pic looks funny, but the charging lead is actually behind the battery.
Trying to show the sharp edge but the V-tail piece is also thin.
Top view of the sanded v-tail.
V-tail piece with the 1/2" line marks.
Side view of the fuse
Fuse with motor mount tacked in place
The HS125's fit in the flap servo bays fine and the included servo covers fit flush.
This is the adhesive vinyl that I used to cover the aileron servos. You can see a small bulge at the rear of the servo.
I used a wiring harness for the wing servos.
This is the HS125 in the aileron servo bay. Just the back of the servo sits above flush.
Shot from above to show the wire routing. I used the heatshrink to help prevent the wires getting into the servo arms. I could take more weight out of this setup by shortening the servo wires.
This shows the servos, rx pack and the rx installed. I used two HS55's side by side with an electron 6 without the cover installed in front of the servos. The rx pack is an odd shape to help maximize the amount of weight that I could squeeze in the n
This shows my mini ChPS charge plug installed just behind where the pod cover stops when installed.
Here you see the tail boom joined to the fuse with 30 minute epoxy. Once the epoxy cured I wrapped the outside of the boom with kevlar thread and soaked it with medium CA since I wanted more reinforcement here.
I used a piece of sandpaper wrapped partially around the tail boom so that I could sand the horizontal stab platform.
Here I sanded the tail boom where it attaches to the fuse. so that it this joint can be wrapped with kevlar thread for reinforcement.
Here is the platform for the horizontal stab with the kevlar thread for reinforcement. The platform itself was glued with medium CA.
I then added a carbon patch for reinforcement to the vertical stab for strength. My scissors are dull and I was not able to make clean cuts in the carbon. Before I applied the carbon I sanded the stab for better adhesion. I soaked the patch with medium CA
This is the vertical stab slid into place to check the fit and mark the area on the stab that I sanded to prep for the medium CA for maximum bond.
This is the tail boom wrapped with kevlar thread in front of the vertical stab to reinforce the boom to help prevent splitting. I tacked the kevlar thread with thin CA then wrapped the boom tightly. Then I soaked the thread with thin CA.
I decided to grind a slot in the tail boom after watching Paul Naton's Handlaunch Build Techniques DVD. The blue painter's tape set the distance I was to cut with the Dremel. I then cleaned the cut with sandpaper to straighten it up (not shown).
This shows the vertical stab installed and the section of the boom sanded prepped for wrapping with kevlar thread for reinforcement.
This is the hole cutout for the wing servo connector.
This shows the aileron servo installed. I basically traced the outline of the servo on the wing between the carbon reinforcement in the wing.
This pic shows both servos and control horns installed with the wires ready for the mini deans connector.
Here is the peg installation. Even by being very careful to start with a small pilot hole in the center of the leading edge to insert the wing peg, the leading edge was hard and fairly thin in this area making it hard to start a hole. The mating hole in t
This shows the carbon control horns installed. These were not included with the kit but I also got these from Atlanta Hobby.
The first pic is what I received with the kit. Not shown is the throwing peg and instructions in German that did come with the kit.
