Halloa people

one of the essential tools for our hobby is a power / watt meter. At some point you will want to know what the Amp draw of your RC actually is.. Can you prop / gear up or not?

Link to this watt meter: ToolKitRC WM150 advanced Power analyser

And here is my show & tell of it

Motor mounting plate of Ghost Rabbit GR1 (0 min 34 sec)


The first part of this video shows the CNC processing of an actuator disk for the diff lock of the Ghost Rabbit GR1. The part will be heat treated after the processing.

The second part of the video shows the motor mounting plate for the same car.
While most of its shape is processed on a CNC milling machine, the final steps of machining the bearing seats and some other surfaces which have all to be concentric are done on a CNC lathe.

A CNC milling machine is by design not capable of providing the same precision for these steps as a lathe. A lathe gives truly round and concentric results because the part itself rotates, not the tool.
A CNC milling machine makes a circle in many small steps, it interpolates the rounding. This is usually sufficient, but a lathe is clearly superior here.

Therefore we go the extra mile and use a lathe for these important steps of the processing. By doing so we achieve a precision for the bearing position of 0.005 mm."

The Nazgul5 is a very good freestyle drone that flies smooth as butter with 4S or 6S battery. The Stack is with F4 FC and 45A ESC's. The video transmitter is 25-600mW and at the front is the good CADDX Ratel FPV camera. The iFlight Xing-E 2207 2750KV motors are great even though they are entry-level motors.

The motor only just bolts up to the test stand .

1s tests , I record thrust VIA the stand and RPM VIA the GT power tach .
2s tests are through the stand ...

I started with the smallest prop that would bolt to the motor , my 65mm prop .

1s - 65mm - 24,600 rpm for 42 grams of thrust
2s - 65mm - 36,000+ rpm for 108 grams of thrust ( motor is getting warm , but not so much as to burn ) 6.7A / 51W

The data sheet shows a 3020 prop

1s - 3020 - 19,000+ rpm for 46 grams of thrust
2s - 3020 - I was very gentle in adding power to see if the motor would cook ..
Around 2A the motor was starting to really warm up ...
I got brave and pushed the motor to 5A for only about two seconds and the motor got finger burning hot ...
No I didn't kill the motor , it lives !
But obviously 3020 is just too much for this motor with 2s ... ( I had to try as it's on the data sheet )
I would run that little 65mm prop 2s , or maybe a smaller 3 blade .. ( dont have any right now ) ...

Wow , 108 grams of thrust for a small 0905 ... Even 1s was not horrible ..

Hello,

To see the First Blog Post of this subject then, please go to:
https://www.rcgroups.com/forums/show...ite-AT-6-Texan

UPDATE: (The KIT has been fully Assembled - FINISHED)

I have performed Weigh-In sessions and taken pictures of just the Dummy Engine "Hollow" Bust in two (2) configurations on the Digital Scale (oz.).

The first is including everything that came in the KIT and I assembled using and following 95% of the supplied instructions from Peter.

The other is leaving OUT the Metal Bolts & Nuts that came with the KIT and the Exhaust Pipe.
(Going to use Tie-Wraps to secure Engine Bust onto the Green three-point mount for weight savings!)

I have also included High Resolution "CLOSE-UP" Pictures of this KIT that was kindly shipped by Peter so, you can see the excellent results using the GORILLA "CLEAR" Glue. This Glue doesn't seem to have added any weight and the Title saying it is "CLEAR" is exactly that because you just can NOT see any residue of Glue anywhere!

Okay, the pictures showing what you have been waiting for (Sort of........).

Oh, as far as the mounting, I have a surprise in store and it will be my favorite thing I do with these models.

Stay Tuned!

The iFlight Titan DC5 is a 5 inch FPV freestyle drone with 222mm. The special thing about the drone is that it has the DJI Air Unit and can be flown with the DJI Digital goggles. The video image is digitally transmitted at 720p 120 frames per second to the goggles. At the same time, the video can be recorded in HD with 1080p 60 frames per second on the drone on a micro SD card. So you really do not need a GoPro camera anymore.

Recently, Guangdong Power Grid Corporation Foshan Sanshui Power Supply Bureau completed the automatic cruise refinement inspection of all 10 kV overhead lines of Nanshan Power Supply Station and has applied refined routes to carry out daily inspections of double-light drones. Nanshan Power Supply Co., Ltd. became the first power supply company of Guangdong Power Grid Corporation to take the lead in realizing the full coverage of multi-sensor automatic cruise. At the same time, it also marks that the UAV has taken a new step in the application level of the distribution network and the level of refined inspection of the equipment.

Using the refined route to carry out "double light" drone automatic cruise

At the beginning of this year, the Guangdong Power Grid Company's aircraft patrol center selected Foshan Sanshui Power Supply Bureau as one of the pilot units for the patrol demonstration application of the drone. The bureau adopted the strategy of first pilot, post-standardization, re-copy, and promotion, and first selected Nanshan Power Supply as a pilot. The power supply area of ​​Nanshan Power Supply Station is 133 square kilometers, and there are 26 10 kilovolt lines in the power supply area. The total length of the line is 284.97 kilometers. The terrain and geology of the area are complex, the gully is vertical and horizontal, and the forest coverage rate is as high as 59%, which is a typical representative.

Thanks to the extreme generosity of one of my flying buds over on the Cox Engine Forum, my currently un-throttled Carl Goldberg "Ranger 42" will be cruising next summer's S.M.A.L.L. Skys behind a vintage "barrel throttle" Medallion .049.

Medallions are sort of an "interim" engine between the good-natured reedies and high-compression Tee Dee engines, and like the Tee Dees, are beam-mounted and will only run in one direction.

The Ranger presently has a Medallion .049 that runs wide open 'till it's fuel is gone and then glides in for a landing. This engine will allow low/slow passes down the flightline, along with the option to land at will (flying bud Tony will once again be asked to step up for these as I shoot some video/photos of the moment!).

Gonna be a fun summer!
Thanks Rene !!!!!!

Good news and bad news.

Lets go bad first, its a shorter story. My company got a new large format scanner/copier/printer recently. Sadly, we also got a new IT company recently, and they can be a little slow to set up necessary equipment and systems for us.
With that said, I was unable to scan the plans into the computer for digital sharing and such. much sadness. When the IT company gets around to PROPERLY setting up the scanner, I'll have those available. I've already met a few people here that are looking for those plans. If anyone reading this need plans for this kit, feel free to send me a DM.

Now on to the good news! The copier portion of this crazy thing works just fine! My boss helped me break out the 36" roll of paper and we were able to make full scale copies of the plans! After a little bit of trial and error, I now have 3 copies of the fuselage assembly and 2 copies of the wing assembly. This is perfect, as I'll be able to take it home, lay it out, and make any modifications I want without ruining the originals.
I will be copying any kit plans from now on. This is a huge benefit and really relives the stress of working directly on the original plans.

Looking over the plans as is, I know there are a few changes to the original design that I want to make.

First desired change: GoPro mount inside the cockpit for a "Pilot POV". I have the Hero Session 5 and it will fit perfectly within the cockpit and provide an epic view (IMO).

Second desired...Continue Reading
