So it has been nearly 2 years since I got my SK450 quad and some fairly serious changes have been made, so I figured I would give an update.
Last year, I finally upgraded it with a dead cat conversion and then this year I have swapped out the KK2 for a Naze32 Rev 5. As a software engineer, I can appreciate the benefits of proper testing of software; so for the Naze32 I have upgraded it to Cleanflight and since getting the PIDs tuned properly, it is the best it has ever been to fly! Another recent change was to upgrade the HobbyKing F-20A ESCs to BL Heli. This was surprisingly easy and with OneShot enabled I do notice a difference over the older SimonK firmware I had previously installed.
After installing the Naze32 and before tuning the PIDs, I did have a decent crash and fortunately all that happened was snapping an arm near the motor.
Where to from here? Well, I am hoping to build a ZMR250 mini quad for FPV. In the meantime, I will continue to practice flying my SK450 and have fun with it. The future of the SK450 is likely to add some longer legs and get a Mobius gimbal so I can play around with some video with it.
Last Saturday I was checking out some local parks at Redbank to find an open area to fly my helicopter. Whilst I was there I ran into some guys flying with Redbank Summerholm Silent Flyers. I decided to head on back there today with my quad in hand to take advantage of the open space to really properly stretch my wings with it; in the hope to try some proper flight and also to challenge myself with flying it in different directions. I was quite surprised at how proficient I was in flying across and towards myself, I guess all the time in the computer simulator has paid off!
For the first time I also managed to set a timer off for the flight time of the quad. In the end it lasted around 7 minutes of solid flying.
I also took the opportunity to snap some photos of the guys planes. (Click on the photos to see the full size)
So the build on my SK450 Hobby King Quadcopter has been completed and I seem to have the settings dialed in reasonably well.
I just wanted to share a full list of what is needed to complete this build, as I have had some people ask what is needed to build one of these.
Just click on the links below to be taken to the Hobby King store for each item.
1x SK450 Frame
1x Flight Controller Protector (not required, but recommended)
1x KK2.1.5 Flight Controller (Reflashed with Steveis modified KK2 firmware)
1x 3A UBEC (not required, but recommended)
4x 20A Hobby King ESCs (Reflashed with SimonK firmware)
Receiver to suit your radio and a LiPo 3S battery to suit.
If planning to do video with it, then I would also recommend swapping to a Dead Cat configuration using the Hobby King Dead Cat Conversion kit.
If you don't already have a USBasp programmer for reflashing the ESCs and the Flight Controller, then you will also need to pick one of these up. If you can get one with the 6-pin cable included, then this will make your life MUCH easier. If you know me, then bring your stuff around with a six pack and we will have them flashed before we even finish the first beer!

Here are the photos from Sunday. Enjoy!
Finally managed to get my photos from Saturday uploaded. Yet to work out the issues that Crazy Domains are having with my FTP...
So I have finally put together a business and website for my photography in the hope to sell some of my fine art, nature and landscape photos.
Please feel free to visit the new website here: http://www.metzypix.com.au/
You can Like my Facebook page there while you are at it too where I will share a lot of my work online there.
Visited the QRS launch again today, first time shooting the rockets with my new Canon 60D. It made it much easier with the higher frame rate, and also the better sensor on the 60D has also made for better photos.
I managed to make it to the QRS launch today, got sunburned even with sunscreen on.... urg!
Was a great day with Dean launching an L motor! And also a quick celebration for Jeff's birthday!
So I got the heli repairs done and all of the settings covered nicely, however it still had a bit of a tail "twitch".
A few times it also spun out (fortunately close/on the ground). I found a few issues attributing to this:
So I have made up some 2mm thick G10 fiberglass sheet from 19 layers of 84gsm woven fiberglass and West Systems Epoxy and it came out quite well. Cut it down to a size to suit the larger size servo with a hole to fit the micro servo I originally purchased for the tail that was too small.
A few flights later and the tail is holding PERFECTLY!!! In fact it has taken out the tail twitch all together!!!
So now I am just waiting for the 118mm long main shafts and I can finalise setting it up properly.
I did a few flights today near my brothers house and took it up much further than I have done so yet and in the mild winds I was mostly holding a good hover! The winds did pick up a little harsh so I decided to call it a day before I crash it again!
All-in-all I am now VERY pleased with the heli! I will also try and post a video soon.
Parts arrived yesterday (a little longer than the last few orders, maybe due to Christmas).
Balanced up the new blades before I went to bed last night and the balancing difference between the new carbon fiber blades and the stock fiberglass is astounding! The originals needed a tonne of tape to get them balanced true (I actually backed it off a tad on the originals for fear that the tape will come off due to the quantity of it!). The new ones have two wraps on the tip of one blade and one wrap on the other at the CG of the blade to balance it's weight to the other.
Finished up the repairs this morning, it appears I got the wrong main shafts, but they will do for the time being. I have ordered (on the slow boat) the proper main shafts along with a LiPo battery alarm to chuck onto it.
Spun it up early this morning and got in trouble with the missus.... sorry love! Did it again after she got up and fixed up the blade tracking and it seems as sweet as now!
