Front differential unit of the Ghost Rabbit GR1 with the steering system attached (0 min 16 sec)

Front differential unit of the Ghost Rabbit GR1 with the steering system attached.

The next parts arrived from a supplier, so we can make some progress with the assembly.
As with our 2WD car, the GX1, the steering system features a dedicated servo saver for every steering servo. However, for the GR1 linkage plates, centerlink and the bracket connecting the servo saver posts with the front gear box are CNC machined from billet aluminum to improve strength and match the cars design.

Trailing arm mount for the Ghost Rabbit GR1 (0 min 19 sec)

The mounting blocks for the chassis side end of the trailing arms for our Ghost Rabbit GR1 arrived. A small but nevertheless important part for the assembly of the car.

The mounting block is designed for low cost of ownership, keeping the expense for replacing components in case of a crash at a minimum.
The design also allows for a large angle of articulation for improved suspension movement.

DustOff #9 - XK DHC2 Beaver Bush Plane - I'm terrible at 3D Mode ;-(

Here is a link to the Video:

I took the DHC2 Beaver out for another DustOff Flight after refreshing my memory on how to get it into 3D Mode.
Let's just say it would have been better if I had just forgotten all about 3D Mode ;-)

For those curious, here are some pics of the installed 12mm lowered twin-motor mounts by MarkQ. In theory, they should improve hand launching the twin-motor setup.

The mounts fit really nicely on the wing. A bit more aerodynamic than the earlier larger versions. I'm using the Brotherhobby 2806.5 2300kv Avenger motors with APC 8x6 props. ESC's were installed under the wing for added cooling.

*I'll do a maiden within the next few days and post about how it handles, particularly the hand launching.

A large surveying and mapping drone attracted many people's attention. This is not an ordinary drone. It is equipped with advanced sensors that can transmit data to the command hall in real-time through wireless image transmission and video cloud services. One end collects data and the other end connects experts and decision-makers. They can be judged in an immersive way."

MMC UAV unmanned experts told reporters that their enterprises processed and analyzed the data collected by the drone through the self-developed drone intelligent processing system, and finally realized the application of data results. At present, the technology has been widely used in the fields of natural resource intelligence monitoring and supervision, eco-environmental protection, and emergency management.

Experts told reporters that drones are a powerful tool for data acquisition. They have obvious advantages in data acquisition, and the data detected by drones can be applied and converted into services, and their value will be infinitely magnified. For example, she said that when agricultural insurance was damaged, it was always taken by people to take damage measuring instruments to the disaster-stricken areas. However, in many cases, people could not enter the affected areas, and eventually, the farmers could report the damages themselves. The data is difficult to be objective. Many insurance companies now prefer to use drones to obtain more accurate survey data.

As an effective tool for obtaining big data, drones can also give a very "effective" reference in many macro-controls of government departments. He Ying told reporters that in the future, big data will be completed by the most advanced collection tools and artificial intelligence. As a mature technology and stable performance tool, the UAV is more intelligent and efficient, so the data acquisition capability of the UAV platform. Will continue to highlight. Mapping UAVs attracts a lot of attention.

Here are the steps I used to convert an HP Power Supply, pretty sure most HP supplies use the same pin out so this should work for other models that may have slightly different output ratings, just make sure the exposed card slot looks similar to what is pictured below. I offer no warranty, only perform this conversion if you know what you are doing!

I bought the following HP Proliant 750W Power Supply HSTNS-PL12 for $15 shipped.

There are 6 short leads on the exposed card slot and 2 large leads for a total of 8 leads. I bridged the left farthest lead to the 4th lead to the right and then soldered up some 4mm and 5mm bullet connectors on the large leads where left side is negative and the right side is positive.

That's all there is to it!

You can put some colored shrink wrap on the bullets if you want, maybe cover the supply with some vinyl wrap if you want to make it fancy.

Here's the previous Thread on this Project:

RE: Accommodating the 3D Printed 9-Cylinder Project!
Busy CUTTING that dang Tough and Hard Cowling with my ROTARY TOOL Set. Then, I finished it with some stainless steel toe nail precision scissors and once I was able to get to the FRONTAL EDGE Smooth part of the Cowl it was a HOME RUN! Hey, it is NOT PERFECT but, I almost threw away Cowl so, it was a good recovery!


Many times this dang AR636 upon initiation it moves my Servos really hard to their end-points. Yes, I do realize the Software operation behind this but, when I Bound it to my Transmitter, I made sure that I Turned-OFF the AS3X stuff but, you could NEVER TURN-OFF these Features entirely and I should know because I can hear the Ailerons move slightly when I pickup the model after a typical flight and the initial sequence it moves ALL my Flight Control Servos something terrible!

I finally solved this by replacing it with a Spare Spektrum AR8000 + SAT.

It is now working like a Charm!

No more violent movement of my Flight Control servos UPON initial program sequence!

Additionally, I performed a Center-Of-Gravity check (several) by placing the battery at it's recommended location within the model and it balanced perfectly!

Here is the ViDEO showing the Park Zone 480 Operational inside the 3D Printed 9-Cylinder Radial Engine Bust.

Tika is another small (16.7m) tug from the WECO yard in Whangarei. They produced some pretty good vessels in the 70s-80s.

Built for Ports of Auckland in 1971 she served in the main Auckland port (Waitemata) until moving across to light duties on the Manakau in 2001. She had a relatively stress free working life other than one really bad afternoon in 1982. She was assisting the 1433 ton freighter Shereen from her berth to the mid-harbour position, and was about to release the line when the Shereen started to pick up speed. The Tikas emergency tow release failed to function and the tug was pulled over and capsized. The deckhand made it but Tikas skipper, since she had been launched in 1971, was trapped in the wheelhouse, and drowned.

A couple of years ago the cement company got a bigger boat that couldnt use the Manakau facilities and Tika was put out to pasture. Last year while it was waiting for sale I was able to get onboard and take lots of photos. POA were very helpful and also gave me hull lines and GAs. Much more friendly and helpful than some of the much smaller provincial port companies.

The model construction was fairly straightforward. For more info on the Tika, and a full build log, visit: Reading

Wow !
Can you imagine my surprise , when a Flashlight ( Astrolux FT03 ) was delivered this morning .
Order date was May 6 , it's Nov 19 today ..
I guess Banggood put in a order with the manufacturer and it took this long for them to get around to making some . ( I guess )
The light was sent for product review , and ..... It was a little embarrassing that it kind of vanished ...
If anyone from Banggood reads this ? , came this morning .

That glider is here , Biplane glider that flies like a rabid butterfly . ( The CG is way back )
Anyhow .... Why would you wan't one ? The power pack ... You want it for the power pack !
I will do a video ASAP , just so you can see / hear what I am talking about ..

UPDATE Pulled the power pack / pictures added !

it's the Mobula 7 V2, and well... this drone is old news now. So why are we taking a look at it 1 year later? As we approach micro season here in North America, the price has come down significantly. I bought my Mobula 7 V2 for around $70 shipped a couple of months ago, and it originally sold for $100+ shipped. In this review we'll figure out if it's worth the price drop. I'll be talking flight, specs, a possible quiet upgrade from the factory, batteries, cheap modifications, and more.

I went back to 18500 batteries in my Frsky Taranis X-lite as the transmitter has a smaller form factor.

Ghost Rabbit GR1 diff lock parts (0 min 17 sec)

This is a more detailed view on the Ghost Rabbit GR1 diff lock parts. The larger part is the locking side plate for the diff housing, the smaller one is the disc which locks one output shaft of the diff to the side plate when pushed towards the side plate by a servo. Once both parts are engaged the positive-fit connection will transform the diff into a spool.
Of course, both parts are made of tool steel and will be heat treated.
