Two boxes arrived today. Both much anticipated from hobbyking.com. The box hold the Turnigy 9x that I’ve bben waiting for. This TX sells so well that it is perpetually on back-order, and the do not allow placing pre-orders on it. Basically you subscribe to their email notification and when you get it, you rush to their site and place your order for it. Normally it sells out within half an hour of the email notification so you have to act fast. Lucky me for finally snatching one. I can’t wait to get all the mods done (I’ll document those on the blog too).
Together with this order, I picked up the Frsky DJT module with telemetry, an extra D8R-SP receiver cause I wanted the PPM signal, Zippy Compact 2200 Lipos, the 9x backlight kit in white, and a few other odds and ends. Now I can actually start taking some stuff apart and modifying it, cause to me that is part of the fun of this hobby.
In the next box I received the sensors that I ordered, cause it wouldn’t make much sense to have telemetry if I don’t at least send some data across. For now I settled on the voltage sensors, cause that’s the most important thing to keep track of when flying. I picked up both the individual cell sensor and the analog pack sensor so that I could get both the total pack reading and the individual cell reading (You will need both sensor if you want both types of readings). I also ordered the sensor hub to tie them both together to the D8R-SP.
Hobbyking was nice enough to throw in a set of Turnigy stickers as you can see. That will work as some cool graffiti for my tool cases. Stay tuned for posts about the mods and how they work out.
Woo Hoo! I just received another parcel! It’s the motors that I ordered on aliexpress.com. These are A2212-930KV Brushless Outrunners and they cost me USD38 shipped. I don’t think you can find a better deal elsewhere. If you do, please drop me a note… lolz…
They came in one of those bubbled envelopes, and they were wrapped in a lot of bubble wrap. On top of that they were individually packed into pretty rigid plastic so everything was very well protected.
This is what you get in each plastic container. The motor and prop adapter are very nice. I can’t really say the same for the motor mount and the 4 screws that came with it. These seem a bit soft so I’m probably not going to use them.
Here’s everything unpacked. What you see is what you get for USD38 shipped. Not too bad.
More stuff has come in. This time from sunsky-online.com. I’ve had good experience with them and I find them much more reliable than GLB, cheaper too.
The 2 main things here are the power distribution board and a bluetooth module.
The power distribution board costs USD0.86 plus shipping. You can’t really beat that. As you can see, it can handle up to 8 segments. The quality of the board is nice and it had nice big pads to attach your power cables to.
The bluetooth module was better than I had expected. Sunsky didn’t really have much specs on it, but their site indicated that the module operates at 3.3v. Upon inspecting the unit and searching around, I was pleasantly surprised that it had on-board regulation for 3.3v-6.5v. So no headaches of setting up a separate power supply when I use this on the quadcopter later.
In case you are wondering, the BT module reports back as a Linvor 1.5, and is actually running the HC06 firmware. This firmware is basically stripped down and only accepts a handful of AT commands. You could if you wanted (with a bit of technical know how of course), load a more powerful HC05 firmware in.
The first part is finally here! I put in an order for a SK450 frame on aliexpress.com. When I ordered this, hobbyking.com had not started to carry it yet, but now they do so you can get it there. I was lucky and picked it up at aliexpress.com for USD26 including shipping so I don’t think I paid much more than buying from hobbyking.com (They sell it for USD17 before shipping).
It comes packed in a small box that got slightly crushed during delivery, but overall, no damage was done and I’m pretty pleased cause everything is packed nicely inside.
Here is a picture of all the parts laid out. The quality of the pieces is excellent. Tolerances look good, and moulding looks precise so everything should fit together well. It even includes a nice set of instructions.
A hex tool and a few minutes was all it took to put everything together. Everything fit into place nicely and nothing was missing. They even threw in a couple of extra screws just in case.
I’ll put up something about the performance of this frame later when I actually get to fly it. I basically bought this cause it was a plastic frame (I’m hoping that it’ll be a bit more resilient than aluminium cause I’m still learning to fly). This particular frame has arms that seem to be clones of XAircraft’s X450Pro which I really liked so I figured I’d try it out. There are similar looking plastic frames like the DJIs and their clones, but it seems that those have vibration issues so I stayed away from them.
Can’t wait for the other things to arrive!
