Congratulations on your purchase of the " V ortex-RC VT-AllRounder
that excels as a 3 channel trainer for first time fliers,
introduces ailerons to intermediate fliers and also
provides a platform for fully aerobatic platform to
perform any pattern maneuver in the book. A
perfect Allrounder.
Please take time to read through this manual in
detail as well as watch our videos that illustrate the
build steps. We recommend that you read several
steps ahead and test fit parts without using glue and
once you double check everything then only use the
adhesive. Our precision laser cutting ensures you will need minimal or no modifications to parts for a
fit, and that all fits are tight and accurate. If you find any part that does not fit properly, please read
the instructions and see pictures again to reorient/align correctly before using any glue.
We have written this manual so that the kit can be built individually as well as by groups of
students/builders. Please follow the build in the order as written below.
Additionally we have given 2 check mark places besides each step.
Check mark the first box when you complete the step. Check mark the second one, after you double
check the step, or when doing group builds have your project coordinator inspect and check it for you.
Watch our build videos, now on Youtube.
From unboxing to the maiden flight, we have it all on videos for you to
see, learn and follow to ensure you get the most out of the Speedsters.

- Page 5 ● Coro, when crushed can reduce strength. Be careful to not crush the flutes when building . ● When cutting coro, parallel to the flutes, always cut in between the flutes using a new, sharp knife/blade. When cutting perpendicular to the flutes, cut in multiple passes taking care to not crush the material. www.Vortex-RC.com...
- Page 6 ● Now we need to clear the hinge joint by removing the plastic material . Bend the joint all the way through, and tape it in place. Carefully run a sharp knife on the edge and slice of the www.Vortex-RC.com...
- Page 7 B. Hold the joint together and “flow “ the CA in place. We prefer to Tack glue using one or two drops , and then flow a few drops through the joint. Remember: Do NOT use CA on the Wing panels. www.Vortex-RC.com...
- Page 8 Note: We have intentionally kept the laser cut parts attached to the sheets so that small parts are not lost when we put together the kits. www.Vortex-RC.com...
- Page 9 Then glue in place. Place the Fuselage bottom sheet on the table so that the small alignment hole is on the right side. Place the Fuse bottom doubler and glue in place, making sure the notches and the cut outs align properly. www.Vortex-RC.com...
- Page 10 Test the elevator by moving it to both sides. It should be free to move. Likewise prepare the rudder by scoring a line 3.5 cm from the aft line . Follow the same technique as with the elevator to create the Rudder hinge. www.Vortex-RC.com...
- Page 11 Fuse doubler. The Right Fuse doubler has a hole. Double check before adding glue. The Servo doubler needs to be glued accurately too. Lay out the Formers A,B,C,D and E as illustrated below. Each former has a top and a bottom side. Be sure to align them properly as shown below. www.Vortex-RC.com...
- Page 12 Take time to accurately fit each of the notches in place, without crushing or damaging the coro. Once satisfied, flow a few drops of CA in place to ONLY the joints in Former B, C and the Wing mounting plate. Doesn't it looks more like a plane now ? www.Vortex-RC.com...
- Page 13 P ut the battery strap through the hole in the battery tray. Make sure you put this in the right way . Glue the battery tray into the right Fuselage section. Note that the notch goes towards the back. www.Vortex-RC.com...
- Page 14 The FUselage bottom should be installed such that the FUse doubler is on the inside. Again inspect and carefully fit each joint and ensure the Coro is not crushed or damaged . Once satisfied, add CA glue to each joint. www.Vortex-RC.com...

- Page 18 Install the wing mounting rods Congrats. This completes your fuselage. Hope you have enjoyed the build so far. Take a short coffee break and we shall then get back to glue the wings together ! www.Vortex-RC.com...
- Page 19 The airfoils are high performance and in order to use them effectively, you need to ensure the wing is not warped or twisted. It is very easy to warp the wings if the instructions below are not followed. www.Vortex-RC.com...
- Page 20 Do NOT mix this up. L abel the wings a nd beds using a marker pen . You should have Wing-L , Wing-R, Bed-L and Bed-R at the end of this step. www.Vortex-RC.com...
- Page 21 L ightly sand the wings before laminating to get a better adhesion. Very gently and uniformly sand using the supplied sandpaper keeping the wing panel on its bed. . Idea is to just remove the thin outer brittle layer of foam . After sanding, clean up the wing with a cloth. www.Vortex-RC.com...
- Page 22 Carefully and gently install the aluminium round spar. You may need to trim the ends of the aluminium spar. Once satisfied, Mix some epoxy, and apply evenly across the length of the spar and gently install in place. Make sure you lay the wing on its bed to avoid warping. www.Vortex-RC.com...

Page 23: Build The Ailerons
B. WHile keeping the aileron deflected apply a length of clear tape along the joint. C. Flip the Aileron the other side, and tape in place using a small piece. D. Apply some more packing take along the joint from the other side. www.Vortex-RC.com... - Page 24 Wing : 9 Cm ) use epoxy to glue the panels and the dihedral in place. Double check this very carefully before gluing.After glueing, inspect the joint carefully, and apply some packing tape to the joint to ensure it doesn’t move while the epoxy cures. Be sure to keep one wing panel propped up. www.Vortex-RC.com...
- Page 25 You can also put the fiberglass tape near the root joint on the trailing edge as shown below, The Fiberglass tape prevents the trailing edge to be crushed when rubber bands are mounted.: www.Vortex-RC.com...
- Page 26 The servo should be installed about 40 cm from the root . Servo extensions should be used to extend the wires out, and the servo wire can routed in the groove pre-cut for the spar. See pictures below and install the Control horn, and linkages. www.Vortex-RC.com...
- Page 27 Whew ! Congrats your wing is now ready. Just a few more checks and we should be ready to hit the field ! www.Vortex-RC.com...
- Page 28 Tip: Wrap the servos in some packing tape before glueing to make later removal easier. Install the Control Horns. Install the Control Horns on the Elevator and the Rudder in the locations as shown below. The Control horn location should be such that they are in straight line with the servo arm. www.Vortex-RC.com...
- Page 29 Keeping the servo centered install it in the second outermost hole. Now cut the rod about 2 Cm short of the control horn, and while keeping the control surface neutral, glue the other clevis also. Install the Motor/ESC and the Prop. www.Vortex-RC.com...
