    Tutorial - Battle H Virus

    Battle H Virus Tutorial Introduction

    I love quads that you can fly and that don't break when you land heavy like I do. While I was waiting for the Honey Badger to arrive on my doorstep over Christmas, being a DIY'er, I put together this little quad.

    This frame is combination of Fleshpilot's H-Virus and Helliyea's Battle quad. Combining these two ideas I have come up with a quad that doesn't break all too easy, and yes I have tried. This is a 400 sized quad that can carry a gopro without the props in view. Another bonus is that most of the electronics are hidden within the quad. This prevents water, dirt and impact damage. It runs on 8 inch props but the same principles can be used to increase the size for different uses/props. I also made this much bigger (550 size) in testing and it worked well. It is completely symmetrical so it is pretty easy to tune.



    The great thing about this quad is that getting the vibrations out isn't too hard. Here in this maiden I have chipped props from an earlier crash test and the picture looks pretty impressive. With new props and more effort into mounting the gopro it should become vibration free.

    Building Instructions

    Step 1
    Cut each 20mm PVC tube to 340mm in length.



    Step 2
    Cut the coroplast length wise. The width is 64 flutes or ~ 190mm. Make sure you use a steel ruler and a very sharp knife.

    Step 3
    Cut the height/length to 365mm.

    Step 4
    Count 12 flutes in and carefully cut the first layer. Cut the 13th, 20th and 45th flute.
    Tip: Score tween the flute with blade/ruler. Then cut through the layer.
    Tip: Cut the side closest to the side of a beam (the deck). This gives more space for the tape and arm to fit later.




    Step 5

    Cut the top plate and the sides to 325mm. The top plate is two parts of 12 flutes. You will be left with the plate where the gopro will mount onto.


    Step 6

    Cut the sides at 25mm and 305mm. This means the back has a 25mm space and the front a 20mm space. Make this as square as possible.

    Step 7
    Mark the center of the bottom plate and arms.


    Step 8
    Add holes for the motors. The motor is 150mm from the center of the arm.
    Tip: Mark the center and then use the motor mount to line up the holes perfectly. So the first drill point will be 142/140.5mm.
    Tip: Put the holes in the middle of the tube. Offsetting it can lead to problems screwing them in later.
    Tip: If you have 16mm/19mm style motors then have one side with 16mm holes while the other 19mm holes.
    Tip: Drill holes right through as it will help with mounting the motors later.



    Step 9
    Mount motors for direction of the feed. I forgot to do this so my wire fold forward not back. Measure out 16AWG wire and solder onto the motors. Don't add gold connectors until later. This doesn't have to be done but it does help with next step.



    Step 10
    Drill a hole in the middle of the arms. ~ 20mm x 12mm.
    Tip: Put on motors and screw them in. then feed wire through.
    Tip: Remember to cut the motor shaft if it touches the wires (picture not done).









    Step 11

    Add extras to the arms such as LED lights. I have each run starting at 45mm from the center of the arm. 2 x 3mm holes are drilled for the wire.



    Step 12

    Put down double-sided mounting tape on the bottom plate. Leave the cover on. Trim the inside of the flutes where the arms mounts. This helps fitting it all in. Dry fit the arms. Don't stick them down yet.

    Step 13

    Lay out everything in the quad. Dry fit everything. Once happy stick down the esc, receiver and LC filter (velcro or DD tape). Add on the gold connectors.
    Tip: The front esc are push to one side (right). This allows a strap for the gopro later. The go pro needs the lens in the middle for no prop in view.



    Step 14

    Take the cover off the double sided tape and stick in the arms. Make sure everything is square. The motors should be 300mm apart. Plug in the ESC. Solder all the wires together, including LC filter, and buzzer/lost model finder (I have mine on the side). Leave space in the middle for the FC. Make holes in the side where the power (for battery and video) cable go.



    Step 15

    Make hatches so you can get to some important parts later. I have hatches for the receiver and FC.
    Tip: Have the FC hatch large enough so you can change the servo wires.



    Step 16

    Add battery strap. I did a quick dry fit of the rest of the gear and balanced it out. Then I made holes for the strap. Also add the strap for the gopro. (I was so excited to be close to the end, I forgot)



    Step 17

    Put double-sided tape onto of the arms. Do NOT stick down. Runs tests for motor direction and make sure you have the esc plugged into the correct ports on the flight control. You don't want to take off and find out that your motor 1 is plugged into port 4 as it will flip your quad and break your best props.



    Step 18

    Once you are SURE everything is working stick the top down. Make sure you stick it down while it is on a flat surface or you will add a twist to the frame.

    Step 19

    Add some double-sided tape to the back of the quad. Cut out a piece 7 flutes high and the same length as the base. Stick it down.



    Step 20

    This doesn't have to be done (I had them spare from my wing build). Add 2x 3mm glassfiber rods in the front flutes. I have mine on the outer edge.



    Step 21

    Get the covering and stick along the center.



    Step 22

    cover the bottom of the quad and the top. I did the bottom first incase I made a mistake later. It meant I only have to take off the top cover to get inside.




    Step 23

    Put props on and go test it. If it works mount your FPV gear and go mad.

    Mini Whaka H

    There are some design changes when building the Mini Whaka H. I will collect and add the information here in the next few days.

    looks to me like you are half a tube of silicone away from being waterproof... (and I bet it floats too).. Nice and clean build.. thx!

    Nice job Whaka! Thanks for posting the build as I may try to build this as well!
    My first frame (Dji450 clone) was a disaster to say the least.

    Nice build!

    What is "Black PVC seconds of eBay"? When I searched I got a bunch of cel phone covers. Could you post an example link please.

    I am not a fan of that folding plastic stuff, but this project has me intrigued. Very nice job, very well explained.

    That is what I was planning on doing. Lots of snow around so I was going to seal it up with silicone. It would be pretty easy to make it water tight.

    I had a clone 450 as well. One of the reasons I built this was that the 450 arms were so damn weak (in the cold). This this can take a huge beating and keep going.

    I'm not much of a fan of coroplast as well .... until I made this quad. It is really stiff and light. Surprised me how much. I did make a larger version when testing it out and that was just as stiff with even more room. But then the Badger arrived and I need it's gear so it only made a few flights. I love this little one as it is easy to transport on the back of a backpack.

    The covering is really just wall deco stuff (sorry my link is in German)

    You can use pretty much anything here. My first version used yellow packaging tape. It add just a little extra strength and makes it look cool. You could also use book covering film. I brought second grade wall decorating material .... 4 rolls of it. I have no idea where the faults are in the material as it looks very clean. I have enough to cover about 100 quads or more
