Stuff for the Diatone 17# has started to arrive

I had a few parcels waiting for me at the post office when I got back from the vacation the other day. I have the frame, motors, ESCs, along with some other parts, which is enough for me to start planning and building the dirty part of the multirotor.

I had planned to use a power distribution board for this build as I had limited success in building the power harness in simple and good looking way before. But I got inspired by Bruce's build video of his chinese mini quad and decided to go for the standard wire harness as it fits neatly between the bottom plates.

The Laser230 IS a Diatone 17#

No doubt about it. Just got my Laser230 from HobbyKing and it is not a ripoff of the Diatone 17#. It is a Diatone 17#.

Review and build video of chinese mini h-quad by Bruce

Bruce (rcmodelreviews) just published a great review and build video of a chinese noname mini h-quad. In his review he compares them in quality and design with the QAV250 and the Blackout mini h-quad. I can't wait to get my own build started, but the motors from myrcmart have not even been shipped yet.

One more millimeter please

I finally got the long frame upgrade for the FPV250. It took Malaysia post no less than 44 days to get it to me and I'm not too happy about that since HobbyKing has launched a third generation in the mini-quad series and I will probably not build anything with this frame. In fact, I have already a ordered the Laser230 / Diatone 17.

Anyway. I had to check it out. Not much too say, it's three pieces of something that looks like thick carbon fiber but feels heavier than expected, a set of metal standoffs and socket button head screws.

I just so happen to have a board camera arrive the same day, a Sony Super HAD-II, which I think is better than the Fatshark cameras I have had before. This frame is supposed to be good for board cameras but no. My particular camera is 1mm too big for the frame. 1mm? I can fix this with a few washers.

New mini-quad motors announced by myrcmart

Myrcmart has announced their launch of a new generation of motors for mini-quads. This was probably some time back, but I haven't noticed until now when I started looking for a budget motor for my next build.

They now offer a slightly bigger version of the 1804, namely the 1806. I fly the 1804 now and I am very pleased, but a friend of mine has gotten much further in flying skills and think the 1804 is not delivering in sharp turns and avoidance manoeuvres.

In addition to this new motor they also have a smaller 1306, it's too small for a 230-250-size but would be very interesting for a smaller build, say a 200. A sub 200 would probably be great for FPV but wouldn't be able to carry a heavier camera (Mobius) for recording.

New mini-quad frames from HobbyKing

HobbyKing announced today their "third" generation of 250-size quad frames. That is counting the intermediate long frame for the original FPV 250.

The new frames are the low-hung clean-dirty frame addition to the original FPV250. I think this design is stupid as it will brake the expensive stuff on a hard landing. However, it has the advantage of being based on the FPV250 which is itself unbreakable.

The next one is a folding 230-size frame. It looks not very thought-through, as those arms wont fold much when there is a motor, prop and ESC on it. And the result might be a half-foldable quad with arm rigidity sacrificed for nothing.

The last one, my pick, is the non-folding version of the above, called the Laser230. It is obvious that it is inspired (please replace by your favorite expression for this thing) by other mini sized quads. It looks less rigid than the originals, having only one "carbon fiber" layer on the arms. It also lacks power distribution.

Of course, I've ordered one right away, my FPV250 v2 will probably build on this frame.






Update: The FPV250LH, Switchblade 200 and Laser230 seems to go by the names FPV250 v3, Mini 200 v1 and Diatone 17#, respectively.

HobbyKing parcels via Malaysia stuck?

It's been 40 days, and counting, since my last order from HobbyKing. And the parcels tracking number is not even registered with my domestic courier yet. I normally receive parcels from HobbyKing, sent with the cheapest shipping option, within 20 days, often around 14. But this time my orders seems to have gotten stuck.

It turns out HobbyKing is blaming Malaysia Post. And they are probably right to do so. HobbyKing says Malaysia Post claims that the backlogs should be cleared by end of June. But I doubt it. Another writer seems to have been experiencing delays already since April. Will Malaysia Post walk the same path as Fiji Post. And will we then get the Hong Kong post service back even with HobbyKing?

Update: My next order was shipped via Singapore. I really hope this doesn't mean that even more delay is to be expected for the three parcels stuck in Malaysia.
