Here is my build of the new Stone Blue Airlines Spark 2.0 I have been working on for a while. Hope you enjoy!
Specs:
Motor: 2212/6 2200kv
Prop: 6x4E
Receiver: Spektrum AR400
Transmitter: Spektrum DX6i
Batterty: 2200mah 3s
Servos: 3x Emax ES08MAII
This is what the kit looks like straight out of the box. You get the EPP Fuselage and wings, coroplast tail assembly (with optional rudder configuration), control horns and linkages, two carbon fiber spars, two tipes of motor mounts, welder glue, and a piece of laminate.
Some kits come with miss-matched black and white EPP based on the availablitiy of the EPP at Stone Blue Airlines. This actually turned out well since I was planning on painting the wings black anyways.
The first thing you need to do is make a trip to walmart or lowes and grab yourself some Goop. The welder provided works great, there is just not enough glue in there to build the whole kit with. Also, in the build video that Stone Blue made, they use t-pins to secure the plane parts while the glue is setting up. I highly recommend you get these, because they made the process much easier and faster and they are less than two dollars at walmart.
Here are my parts after painting. I saw a paint job someone else posted online and I thought it looked good, so I based mine off of it. All you have to do is take some duck tape and tape off your design and you're good to go. However, if you have black EPP and you are trying to paint it, I would recommend painting it with primer first, or you'll have to do about ten coats of paint.
Wings and tail are glued, now its time to laminate the fuselage and add all of the electronics. One thing I will say about the laminate is that they do not send you quite enough to cover the entire plane with it. I knew this may be a problem and it covered the fuselage easily, but when I finished it, there was only enough to cover about half of the wing. However, its not absolutely necessary to cover the whole plane with the laminate. Without the laminate the wing is still rock solid.
First I took a piece of wire I had laying around and bent to the shape of the servo I was installing. In the build video StoneBlue posted, they used a Soldering Gun to hot-wire cut their shapes out. Since I dont have one of those, I used my lighter and some pliers to do the job. Just hold it in the flame until it is almost red hot and then press it into the EPP to cut. This took a little while to do and several passes, but it is much faster and easier than trying to cut the holes with a knife.
First servo is installed and working, now on to the wings with the same process.
Here I used the t-pins again to hold the wing in place while it is glueing to the fuselage. In this picture you can see that I used a much thicker carbon fiber spar than what came with the kit. This is because my wings were a little warped straight out of the package and this carbon fiber spar aligned them and holds them in place much better.
Glueing the motor onto the fuselage. Once again using the t-pins to hold it in place. Don't be stingy on the glue here!
Next up was running the wiring. One way to make it look sleek and sharp is to cut shallow channels with a knife and then use a popsicle stick or some other small blunt object to push the wires into it to conceal them.
Everything is finished up and ready for the maiden flight.
This is easily the most durable plane I have ever had in my possesion. On the maiden, I nosed it into the ground while trying to trim it and it took it like a champ. No wrinkles, no scratches. Once I got it trimmed and flying the way I wanted, I was having a blast! It flies so easily and handles the wind pretty well also. Now I just need to add my FPV gear to it!
