FrSky makes a nice range of RX choices and VD5M felt just right for the tiny HK Pocket Quad.

As with my previous Pocket Quad build, I un-soldered extra connectors, re-soldered battery connector at 90 degrees for better access. I went with the same weird RX channel order like last time with the only difference that the previously empty PITCH channel on the board must be actually AUX1 for angle mode selection (and indeed all channels worked as expected based on the order that I established last time with my trial-and-error approach).

This time I had to burn the missing bootloader on myself with USBasp and the rest went without hassle via USB cable as in last build, no need to make any changes from my previous Pocket Quad v1.0 build with V8R4-II RX.

I used Elmers glue (same as Gorilla glue) on plastic arm attachment, to support wire solder points and the tiny RX antenna connection point. This glue foams nicely a bit and is not too stiff or brittle once fully cured.

For landing gear I used pinhead needles with 11mm tubing to fix them all at the same length. This worked out real nice (the pins idea is not mine, saw then used before and just added the tubes) and the 4 pins with tubes add only 0.5g total weigh to the quad. See the pics below for yourself.

I also roughened up the shaft surfaces with sand paper and added a tiny bit of Elmers glue to the inside of the prop hole before pushing them on the shaft. 2 green props up front help with the orientation, a bit nail lacquer to balance the two CCW props and it flies real smooth.

My favorite small quad (that I also build for my beginner buddies) has been F330 with Turnigy Aerodrive SK3 2822-1275 motors and carbon or SF 8045 props.

However, HobbyKing just brought out an even smaller kit with with FPV250 frame and Multistar 1704 Motors and ESCs. Just add your KK2 board or HobbyKing HKPilot Mega Mini Flight Controller, a RX and off you go. There is a cheapo pan/tilt included (not the FatShark stuff, don't be fooled by pictures )

Needless to say, I have on my way and here is my buddy code for the fist one to grab it:

Save US$: 12.60

HKPilot Mega Mini looks like a perfect tiny autopilot choice for a my favourite small quad setup with F330 frame. I have started to build one F330 frame with the larger HKPilot Mega V2.5, but now there is an even better choice.

You can grab one for yourself with my BUDDY CODE here:

Some of the stuff you are going to need for a nice F330 frame setup besides your choice of a flight controller (KK2.1 or HKPilot) is following:

HobbyKing just started selling "Mobius ActionCam a 1080p HD Video Camera Set With Live Video Out".
I just got one Mobius camera as an alternative to my GoProv3 and HoryzonHD 1080P FPV cams from Hobby King and if you want one too, then here is my BUDDY CODE to save you about 3 USD: C73AF010-99CF-424E-AB8C-11A5A9E8B2E3


PS! Make sure you add Mobius cam accessories to the cart while on the Mobius cam product page, this way accessories are much cheaper than when added to the cart differently.

I have not been active on this forum for ages and never bothered to blog, so why not a first entry.

I have a lot more toys (mostly in the form of parts ) than I have time for my toys. One of those, long overdue was a HobbyKing Pocket Quad kit. I finally got it set up and flying, using a normal PPM FrSky 4 channel V8R4-II RX and Turnigy 9XR radio with DJT module, flashed with er9x firmware.

Why this receiver? I only use Futaba FASST, TSLRS and FrSky DJT compatible stuff, thus DSM2 was useless to me and V8R4-II was the smallest one I had around (I also pondered about using PPM_SUM FrSky D4R-II, but its features and long antennas were way overkill for this tiny quad).

The really weird part was the channel assignment issue with my normal PPM RX that really baffled me. Thus (as I did not find clear use cases of V8R4-II or much of other normal PPM RX with this HK Pocket Quad), I am writing down my steps here for other to follow or to comment where I must have gone brain-dead before opting for my channel re-soldering hack.

I pretty much stared with RCGroups thread on HK Pocket Quad and followed the instructions of J.E.B in the first post with the difference that I used the latest Arduino and for MultiWii stuff I used the MultiWii_2_3_pocket.zip file from "goebish" blog. I just commented out the Spectrum DSM2 and SBUS crap as follows and used Arduino on Linux to compile and upload the code to the Pocket Quad:

//#define SPEKTRUM 1024
//#define SPEK_SERIAL_...Continue Reading
