Your housing for your KK2 has inspired me to look through the good lady wife's tupperware cupboard.



I think I'll keep looking. The gravy lid is likely to fly off and the handles will cause drag, other than that, I liked it.

I am starting to get worried about you Marschy :-)

Prototyping a flight control board mount out of paper from the laser printer. This will be printed on glossy magazine paper then ironed onto Copper PCB board, then soaked in water to leave the black pattern on the copper, then etched. Should look cool.

Here we go

Clean PCB and create negative on glossy magazine paper.



After ironing negative onto PCB and soaking it in water to remove excess paper, tidy up negative with PCB pen, prepare etchant.



Almost there, takes about 10 minutes, depending on temperature of etchant, warmer the better.



Finished Flight Control board mount on top of quad ready for KK2.1 Flight Control Board.

So that is how you make a PCB these days. We use to screen print them and then etch them. But that was when I was a lad.
Your mount looks very cool.
Printing the pattern on the glossy paper was that done with the laser printer?

Yep laser printer, one for about $150 from office works. When you print the negative, crank the contrast up and turn down the brightness of your laser printer so it gets as much plastic in the print as possible then it sticks to the copper when you iron it with less effort. Thinner the glossy paper the better, but it must be glossy.

So Marschy how was your weekend?
I got my Tri to fly today and then burnt out another servo so scrapped it and built a quad instead. I need to tune it a lot and it is so much harder to fly than my F450 with the NAZA.
We even got a new Tx Rx being the Turnigy 9x cheapy. It seems to work and I have figured out how to set it up for what I want.
Happy Flying
Regards

In typical fashion, OCD got the better of me. Once I made the PCB for the the flight control board, it got me thinking about other stuff I could make that requires a PCB, so at the moment i'm making navigation lights out of single 5050 LEDs which only require 3.3 volts. The first effort I burnt out the power regulator cause I connected it up wrong and cooked two transistors as well, working on the mark 2 version as we speak which has markings on the PCB so I don't get the wiring wrong next time.

Home made one. I'll post photos after Saturday as I have burnt all of out internet for the month and are shaped. (SO I can still do forums cause they don't use a lot of bandwith)

Crikey I'm slow compared to you, haven't got my 450 in the air yet and in the same time you've already crashed one and burnt out servos (2?) in another. Your going to have to consider changing your user name, have you considered "Crashnburn"

You guys inspired me to dip my toe in. I bought a Walkera QR W100S and a Devo 7E TX from bang good. I know the video isn't that crash hot, but the ability to record direct to my Android phone tipped me over the edge for it. They also sell a little hard case for it, so grabbed that so I can throw it in the truck without worrying over it. Should be fun to get some footage while out 4wd-ing and camping. Ordered it last week, so I guess I have a few more weeks to wait for it to arrive.

Gday Sawed_off, the props on these walkera's are the same on my UFO. They have a self tapping screw that goes through the hub of the propellor and the prop is made of pretty brittle plastic.

Go shopping for replacement propellers on eBay now, you can pick them up dirt cheap if you are willing to wait for international snail mail. My UFO has foam prop guards and I still manage to scratch the hell out of my props. Without prop guards, you are going to break a few props at first and probably rather quickly. Your radio is great, much better than my UFO transmitter and it will do for a much more featured quad as well, The foam guards are coming off my UFO some time in the near future. I think you'll find yours is much more zippy than my UFO, no prop guards means it won't be carry much weight around.

Your going to get hooked when you see how bloody easy these things are to fly.

Cheers, Marschy

Yeah, I grabbed a swag of things. The quad, radio, case, props, spare cw and ccw motors, and a couple more batteries. It should be enough to get me into mischief.  ;D

I'm trying to finish off jobs I've already started instead of jumping from one thing to another. So I finished off the transmitter battery conversion from 8xAA to flatpack LiPo, and I've finished the second ESC reflash this evening.



The ESC's with clear heatshrink are the reflashed ones. The black ESC's are the controllers before reflashing. Sticker on the back is 'HW 30A' (Hobbyworld?)

Soldering the ESC is proving to be tedious, my crap eyesight has made me resort to using my Canon Ixus 115HS camera which has a bloody good macro (5mm-20mm lens). When I want to inspect my work, I take a photo then zoom in on the LCD display, and I can see everything on the PCB crystal clear.

When I got home last night from work we made a new frame for the scratch built quad. I was not really happy with the modified frame I was using.
It is a basic frame with a square body and X arms off the corners. Fitted up all the gear for a test flight. Well that was interesting. Some tuning is required.
I crashed it and broke modified one arm but it still flew.
Got up this morning and had a read of some forums to get some ideas. It seems like I should flash the KK to Stevis 1.1s2beginner or something like that as everyone says it is good. Until my flash tool gets here I will have to use what I have. I am waiting for the battery to charge again so I can do some more tuning.
I did discover it is best to have the correct motor rotation to make it fly best. I had 2 motors reversed so had the toilet bowl effect when flying. Changes made and now it flys better. I still have much to learn but it is fun constructing different things.
I am looking forward to getting the new quad just to hover. I can get it to fly around the back yard in some sort of fashion.
You will have to wait til at least Saturday for me to post photos as I need full speed internet to do that.
Regards

Crispy's tip of the week.
When setting up the kk2.1 and you do the reciever test you should adjust the Tx subtrims so that with stick centered all values are 0.

Ordered it last week, so I guess I have a few more weeks to wait for it to arrive.

I just realised I ordered it all during Chinese New year, so nothing is moving in China for at least another week. Plus a couple of parts are back ordered until 20th of Feb. *sigh*

Oh well, I guess I should do some maintenance on my camper before we get cracking again this year.

I've learnt a valuable lesson flashing my speed controllers. Not all ESC's will flash from the ports on the PCB.

I've successfully flashed 3 controllers, but the forth one just doesn't want to play the game.

I've had to order an Atmel socket firmware flashing tool so that I can flash the last controller. I can calibrate the ESC, bloody thing simply wont flash.

Saturday is here so as promised here are the latest photos of the new quad after the tri burnt out the servo again.

Here it is. I might have to shorten the arms a bit.

The custom landing gear is rings of 70mm PVC pipe and they give a nice spring for hard landings.

The underslung battery holder and the frame sandwich.
.
A square middle frame keeps things symmetrical
Having fun trying to dial it is.
