Hi again

Some time ago I became a happy father of twingirls, so there was absolutely no free time for my hobby, but... Welcome to the buildlog of my new "child" - ZOHD Nano Talon.

I was seeking for smallest platform, which can handle PX4/APM based FC, because now I need to put a baby carriage in my car and there no space left for lovely Bix3

So, this is a list of goals I want to achieve:
  • ~40 minutes of flight time
  • "digital" fpv (wifibroadcast)
  • autonomous takeoff/flight/landing (arduplane)
  • make RC Transmitter optional
  • (optional) long range telemetry

And list of used (or planned to use) parts:
  • ZOHD Nano Talon 860mm Wingspan KIT
  • ZOHD Nano Talon 2204 1870KV
  • Furling32 BLHELI ESC
  • ZOHD Nano Talon 8g Digital Servo
  • APC 6040 6x4E
  • JMT Pitot Tube Airspeed meter
  • OMNIBUS F4 Pro (V3)
  • MINIAP GPS Ublox7 w compass
  • Matek Mini Power Hub PDB
  • Wireless LAN NIC module AR9271
  • RG178 Extension Cable
  • Raspberry Pi Zero
  • Raspberry Pi 3 Model B+ IR-CUT Camera
  • Raspberry Pi Zero Camera Cable 16 cm

XK Edge A430 New Motor & Prop Test Flight



Here is a link to the Video:
https://www.youtube.com/watch?v=1WRUvUE8Pl0

Wind is out of the Northeast at 3-5mph.
I finally received my replacement motor for this plane.
I'm using the RacerStar BR1306 3100kv 1S-2S Brushless Motor.
I measured the AMP draw on this plane with the original motor and prop and it was pulling 2.91 AMPS in a static position.
I can't be sure the stock ESC is rated for more than 3 AMPS, so I installed a Gemfan 4045 prop on this motor to keep the AMP draw low.
In a static position the RacerStar BR1306 3100kv motor and Gemfan 4045 prop were producing 142.4 grams of thrust @ 3.9 AMPs.
Since the motor and prop will pull approx. 25% less AMPS moving through the air that puts it below 3 AMPs @ 2.9 AMPs.
I had to move the motor forward 8mm in order for the prop to clear the fuselage as the original motor had a long plastic prop hub.
Even after moving this motor forward 8mm I was able to maintain the CG of the aircraft.
I believe this motor and prop combination will be producing approx. 20 grams more thrust than the stock motor and prop.
This was also the first time I was able to complete an FPV flight without incident and test the acrobatic capability of this plane.

Began assembling the 1903 Wright Flyer 24 static. Full kit. Rib-ticklin fun!

So far the plans are very clear and accurate.

I finally got my "Super" Sonicwake 36 into the 70+mph club! The gps logger got the boat at 71mph and the Gps device got the boat at 70.7mph. This custom prop was created by Chris Hoffmann (dasboata). The little boy Dwayne came to fish with his family but his fishing pole never hit the water he was so interested in the Sonicwake..Lol!

My vintage Estes model rocket launch controller from middle school has finally been retired. Unlike the more recent 6v systems that rely on AA batteries in the controller and a separate launch pad, my old system featured a launch pad that was designed to fit on a 12v lantern battery. It was simple and very effective.

After completing the Slow Poke I set my mind to knock out a series of smaller projects like building my son a 1/2 A control line airplane and restoring my speed 400 Bristol Scout and Super Cub to flight-worthy status - replacing my old Estes launch controller was on the same list. However, rather than a restoration or new purchase, I decided to build my own system with a rechargeable 12v battery and banana plugs linking it to a controller featuring a key switch, LED, and toggle switch for launch. I was also eager to find some better alligator clips for the igniter. The system was easy to build with a schematic from Estes and a small order from All Electronics in CA. Plus, rather than spending a small fortune testing the system with costly igniters I wired up a 12v automotive bulb.

While at it I used a carbon fiber rod and some plastic caps to make an improved system for carrying the lunch rod.

As soon as the weather improves we'll test my son's egg carrying rocket.

Here it is:

https://www.banggood.com/MZ-YY2003-2...r_warehouse=CN

Disclaimer: I got this from Banggood for testing and review.
(Note that this is NOT an affiliate link. I do my reviews because it's FUN, I get to play with stuff that I might not otherwise buy, and to give others a real life clue (not the manufacturer's claims) as to how the darn thing works! Also, if you think I'm biased and won't knock an item that needs knocking, then you need to go back and check some of my other reviews...)


For 44 bucks, you can already guess that it's a toy. No problem there! The package shows 8+, but... if you have a kid on your Christmas list that's older than his 6 or less than his 12 years old, then it would be a real nice gift! After I'm done going through testing it for my review, it's going to my 6 year old grandson. Trust me, he's going to be one very happy kid. It's fast enough to get his attention and strong enough to have some good fun, yet slow enough that he isn't going to get into trouble (good luck with that, eh? ).

Ok, here's a quick sub 30 second video that will show you it's speed and crawling ability, so it shouldn't endanger anybody's attention span:

MZ YY2003 Military Crawler (0 min 28 sec)


What do I think, remembering what I see as the target age group?

Pro:
Decently fast
Decently strong crawler
Typical (easy) controller
Headlights work
Has what sounds (to me) like a backup warning sound when moving
Yes, it has reverse (I absolutely hate those toys that don't!!!)
Trim adjust for straightness
Trim adjust for speed

Con:
Could use a somewhat tighter turning radius

Thoughts... At this price point, I don't see much that's any better and certainly a lot of stuff that isn't as good.

This week the guys over at ProfiCNC who make The Cube (Pixhawk 2.1) announced a new product called HereLink.
An all new digital wireless transmissions system with built in remote controller.




Consisting of a RC Ground station and Air System HereLink will allow users to get long range HD video and control link up to 20km in FCC. The Ground Station is a RC that is of similar design to the ST16 from Yuneec with a dedicated 5.5 1080P Android based tablet built in, It will ship with a custom version of the Solex App to give Video, control and telemetry all in one unit. Being Android based it also means it should also be compatible with other app like Tower too.





The Ground unit will have a number of programable buttons along side the two standard control sticks, two rocker switches, a wheel and six back lit buttons along the bottom. Tablet connectivity consists of Wifi, Bluetooth and GPS for position data and whole unit will be powered by a 4960mah rechargeable battery.

Yes, CA glue is faster.But i am in no hurry. Getting one side framed up in a week. Two glue joints a night and one in the morning. I use a brick to hold the frame down rather than t-pins. It allows the plan sheet to be reused. Close enough is good for me.
