+++++++++++++++++++++++++++++
It takes awhile to write a good instruction manual and this is kind of a draft per-say.
You will need:
Covering Iron
Exacto Knife
Scissors
Masking tape
Medical tape
square
Rubbing Alcohol
5min Epoxy
30min or finishing Epoxy
Thin CA
wire cutters
Needle nose pliers
for electronics you will need:
2 wing servos, i really like the Dymond D60 (HV capable), Hyperion DS09SCD all around good performer and a DLG standard for most pilots, or the even better (but same case as the DS09) Airtronics 94802. The 802 is the best centering servo I have ever used, bit pricy but performs well on 1S lipo and has awesome resolution.
2 fuse servos, The Dymond D60 will work here but if you are shooting for 10oz or under use the d47 instead, it is sufficient torque and speed wise. The DS09 and 94802 will also work well and are just a bit heavier and 7g and change. The Airtronics 94800 is another option and what I personally use in this build, they come in at 5g and perform great.
1 flight battery. I use 1s 1000mah lipos, they charge fast, don't develop memory and are super light. I still had to add a few grams of nose weight for balance but I try to stay away from NIMH or NICAD whenever possible. If you go with all dymond servos then stick a 2s lipo in there! :rockon:
Kit Contents should include:
2 wing panels (right and left)
Pod
Boom
Horizontal stab (with surface pre-hinged)
Vertical Stab (with surface pre-hinged)
Plywood Jigs
Carbon Tow
Fiberglass cloth
and general hardware pack
Finished model will look similar to this:
Pre-assembly
Start with the Plywood jigs, these pictures should help you figure it out. There is no order or special position, just make them look like mine. These will be used to glue the boom on straight and to keep the incidence correct on the horizontal stab. Do not skip this step.
You do not need to glue them together (you can i suppose....) they are fine with the friction fit.
Go over all seams and take out all of the wrinkles. These come from China to Colorado, things are going to expand/contract, nature of the beast.....
Fuse and horizontal prep work
This is where I modify the plane for Pull Spring rudder and elevator control. I get rid of the stupid pushrods and pushrod guides. these are the things wound up at back of the pod. Just cut those off with a blade. We will be running the strings inside the tube. This saves a lot of weight in a very weight sensitive area.
Start by opening up a hold right behind the horizontal stab pylon. Try to take as little material as possible. Wrapping masking tape before you start cutting with the dremel will prevent chipping (sorry, not pictured). You will need to grind into the pylon a little in order to clear room for the string to exit (first pic you can see I had to go back and do this)
Sand the lower portion of the control horn with 60 grit, make sure you can see lines in the G10.
Cut a slot with the exacto knife directly in line and square to the hinge line for the control horn. Use the control horn for reference on depth and length of cut. Glue control horn in with thin CA, do not kick, it it dry by itself.

Reserved for Stab mount and control horns
First ensure you are getting full deflection on the rudder and elevator, should go past 90* if you desire.
Take a 4" piece of .006 music wire NOTE: I have yet to find out if this is enough, I used this on composite birds but everything moves a little smooth than a built up plastic covered airframe. I reserve the right to change this diameter later. the included pushrods may work for this. I still need to test this though.....
Bend a 90* angle 1" from each side, 90* to each other. Two bends total. Please look at my picture of this before proceeding. Make it look just like mine.
Holding your horizontal stab, hold up the wire with one of the 1" sections facing the elevator. You will need to orient the wire (spring) so that while in rest state you will have a bunch (close to 90*) of elevator UP throw. you should end up with it looking like this, with the unloaded state being UP ELEVATOR THROW
