CobraHD_hd39 Use Manual.zip
No lens holder for gopro. Here I am using my sd camera.
Here is my homebuild quad.
next to my rcexplorer.se for size.
with arms. weight 156grams
All fit on 300 x 150mm board
top (left) bottom (right). They can be swapped around if wanted.
The top plate is on the left and the bottom plate is on the right. the nose has a hole for my pan system. he two square are - for two different types of board - are the at the CG.
The front hole fits a part of a pan/tilt system I brought from china ;) I am only using the tilt part of it as it has no slop. The middle plate will hold the landing gear .. maybe.
this is the underside. the back has holes for the battery strap. The bottom plate holds the OSD, battery, control and camera. it is soft mounted
Top. the distance from the top plate and bottom is enough to fit all wires in. So the top plate is a protection plate. On the top will go the video tx. The 3 holes in the front are for the wires.
on the yellow will go the control board. On the red yu can just see where the power board will go.
The three boards.
The layout that I am thinking of going with.
This is with the top (blue) removed. the green is a KK board. It is placed over the CG. the middle plate (red) helps hold the arms. The lower plate holds the camera, OSD, battery and control board.
see there is no more toroid core on the wire so you can cut it shorter and add the board on.
under. ops I wired the creamic cap wrong .. still works.
from left to right. power out, 104 cap, 470u 16v cap, toroid core (same that came with but more wraps), power in.
This is how I have wired it up. I have 3.3volts coming from a ubec. 12volt for the camera. This was only a test not to go on the plane. I have no picture apart from a blank screen.
homemade plug. easy to fit a 2.4ghz or 5.8ghz receiver and antenna. For the 8km run I had a 8 turn helical strapped to my head.
here is my lastest wire diagram. It has changed a little. There is now a -ve going from the cam to the DOSD. The -ve has been removed from the DOSD to the RX. The bec's -ve has been connected to the RX.
hot glued in. the program cable is out the back ready if needed.
the sides are made a little long to bend in. this turns the wire behind the camera and blocks water coming in.
put shrink over top. lightly shrink it. then cut out around the lens cap with a sharp knife. heat again. makes a very tight fit later.
In this picture you can see the LC filter. Near the GPS.
video transmitter. It will come out quick to change frequency i was to fly. either 5.8ghz or 2.4ghz
The receiver. Adding a buzzer in there is case i dumb my plane in tall grass. Since I fly low that most likely will happen.
I made some short connectors for the maiden. The hatch will go on after and i will dig the battery bays in then. DOSD installed.
The wing so far.
Bottom with my old runabout
my bread board for the e-osd. the red thing is a lc filter
the guts of it. Nicely sunk into the foam and covered. I am thinking of sinking in the batteries wire .... if I get around to it.
This is my sanding tool to get a good profile for the leading edge. I made it by cutting out two pieces of card and then use a hot wire to cut the foam out. I ripped the paper off. Then just went along the leading edge and sanded it all down prefect.
wing now is turned over and I started adding all the gear on it.
All the spars. This is the bottom of the wing so they don't get in the way when I sink all the gear in later.
Adding the wooden spar. It is covered by the top layer
This is all the cut out parts in 6mm depron (apart from the top cover as I made that later).
I need the black part. What is it called and do you think they are easy to buy from a local electronic shop.
The finished cable. Very simple and very easy. Works very well too :)
The parts I used. Here I have enough to make another one ... if needed.
here it is with all the gear on it. I hope like hell I have the right COG now :D
What are A and B? any others you think I will need?
1km and nothing wrong here.
Getting pretty clear this far away. Looked prefect in the goggles.
You can see that faint line in the bottom left corner. That is the road. The wind drifted me over just a little and my signal went like this for a short time. There seems to be a very narrow band to fly in. Does that sound right that far away?
Again around the same area. Looks not bad.
This is 4.5km away. Not perfect but very easy to fly in. I think my recorder picked up more static than my googles. It looked much better in them.
My second. Arh the memories these bring back.
My first ever FPV plane
CAmera in a box. Worked very well and stopped many crashes from smashing the board.
For markus. Close up of the hecker transformer
you can see the vtx in the tail. I have carbon strips either side of the vtx for strength.
Number 2 and this one had the truly amazing pan that wobbled with the wash of the prop. Still in need of CP antennas. Still was damn fun until it met a untimely death of flying below a hill.
My first little FPV plane. Damn did it need CP antennas. but it was a load of fun and once I crashed it .... along came number 2 :)
so close to 6km but I had to turn around. Damn you weather!
no worries and it wasn't as hard as I thought.
the wire just comes from a linear antenna that I stripped off.
My homebrew 6 turn helical antenna for 5.8ghz
okay the spacing is 12.903mm but who is counting??
Here it is. a 5.8ghz Helical antenna. I have added some hot glue at the joints for extra strength.
This is for 5.8ghz. 6 turns.
My ground station. The antenna on this has been removed and replaced with the SPW antenna which looks a little like the one on the tail of my plane.
Here is my twinstar with the antenna. Doesn't it look great all new? lets just say that that newly painted shine no longer is there. :)
This is what I need to do. I am going to cut out 3 more pieces of plywood to make a triangle shape. This will get the antenna pointing vertically more often.
Here I used Velcro. I took out the 35mhz module and covered it with plywood. It sits there very tight.
yellow - PPM black - ground other black not connected red - power
My son holding it. Damn it didn't fit into the boot of the car!
No 2. The white beast!
OSD at the center
LC filter at the center
Feel the power
goes much faster now.
506 grams that is 17.81 ounces. Too Heavy?
