Just finished painting the top of my V4 FJU.
Gone for a nice bright red and yellow scheme this time. Yellow is a really good color toof include for visibility I have found. Wanted to try out the red too, hense what I've done here.
Shall probably be sticking a 36mm MEGA 22/50 1EE 100K motor in this one along with a Castle edge 200 lite with a 6s 4500 or 5000mah high C lipo.
Should be 200mph capable plane, maybe slightly more depending on airframe drag/trim etc and prop choice.
Shall take my time on this one to get it as perfect as I can
The stock BL180 3000Kv Motor is easily removed by unscrewing the single set screw and disconnecting the power cable.
At this point, carefully remove the Foam Prop Spinner from the 120mm x 70mm 3-Blade Prop by scoring around the base of the Prop Spinner with a sharp Xacto knife. Then remove the 120mm x 70mm 3-Blade Prop from the Prop Adapter holding the Eflite BL180 3000Kv Motor by unscrewing the Prop Screw that is holding the Prop and stock Prop Adapter together.
Install the new Eflite BL180 2300Kv Motor in reverse order, along with the Prop Adapter (plastic or aluminum) installed.
Then re-attach the 120mm x 70mm 3-Blade Prop to the Prop Adapter and secure it with the Prop Screw.
Re-glue the stock Prop Spinner with a light drop of Foam Safe CA or Rubber Cement. Make sure the Prop Spinner is centered and rotates evenly.
I haven't been upgrading my computer for last few years but as I've been doing more Image processing, I found myself needing more processing power with multiple GPU. The only thing was that my pocket book would allow me to purchase much of an upgrade over what I already had. (i5-3570k based ) Recently, I've been seeing used Xeon Processors for low price on Ebay. Xeon E5-2650 is sandy bridge CPU with 8 core and 16 thread running at 2.0ghz (upto 2.8ghz turbo) and I found one on sale for 25 bucks shipped. I've also recently picked up an E5-2670 for 70bucks shipped. (which will be used as upgrade)
These Xeons are lifecycled out of server farms, but they have been ran conservatively and have lot of life left in them. They also uses DDR3 Registered ECC Ram, which are also available used. The only problem is that these processor requires certain motherboard. I have found new motherboard with X79 chipset , but they were 160 bucks or so. Because I wanted to run at least 2 or 3 GPU, I could not use pre owned server motherboard which are about 100 bucks with First gen E5 xeon, you couldn't run X99 board (which can only run with 3rd gen I believe)
After some careful research, I ran across used HP workstation that could run E5 chipset. HP Z420, Z620 and Z820 were originally sold as high end workstation with Xeon . Z420 is single CPU version while 620 and 820s are dual cpu version. I...Continue Reading
It is with great pleasure that I can finally offer a video of the Yoni tricopter that was constructed last year . As I was finally able to scrounge up the remaining parts from a crash victim , this 'leftover' was realized . My rcgroups mates Sam (CO2X) , and Dennis (cynr100) were instrumental in their encouragement and advice with this project . Thanx mates ! Without their help . I doubt that this would have ever left the work bench .
As noted in an earlier blog posting of this model , its main frame construction is of Lite Ply , StyroFoam and some salvaged aluminum square tubing from an old handrail . The features of the Yoni include a KK2.1.5 flight controller running RC911 firmware , generic 30 Amp ESCs on Gen Ace 3S @ 2200mA power , Emax CF2822 motors twisting Gemfan 10 X 4.5s and my usual wiring hardware trix . This AUW of 950 grams in this configuration yields flight times of approximately 5 1/2 minutes on factory default settings .
The video included is of the Yoni's 2nd ever flight and is the raw footage of that . It is dedicated to my mates Dennis and Sam , of course as it would have never been possible without their input . The stock / default settings of the firmware yielded a flight that displayed exceptional yaw rates and decent lateral and fwd / back transitions . The 'punch outs' are a little weak but may be possibly solved with a different motor /...Continue Reading
Drones in Visual Journalism. The New York Times staff photographer Josh Haner was an early adopter of drone photography. His earliest forays were with a $60 gadget that he maneuvered around his living room. Since then, he has aimed ever higher, making videos and stills high above the Gobi Desert and the Marshall Islands. He has embraced the technology in ways that add a stunning dimension to his storytelling, while at the same time presenting unforeseen challenges. His conversation with James Estrin has been edited for length and clarity. https://lens.blogs.nytimes.com/2017/...urnalism/?_r=0
Built For Brushless
We built the E-Revo for brushless power right from the start. For other companies, brushless-ready means just making some nominal provisions for battery and motor installation and letting the aftermarket develop the upgrades necessary to make it survive. Not Traxxas. We heard the call for more power, so E-Revo was tested tough for durability with brutal 6S LiPo power and intense custom-wound brushless motors. For the uninitiated, this extreme 65+mph motor monster truck is ordinarily a predictable recipe for a box full of twisted and mangled parts. Not so with the Traxxas E-Revo Brushless Edition. E-Revo's driveline has been engineered to endure the kind of horsepower and punishment that's possible with today's motor and battery technology. It looks factory because it is factory, complete with a separate motor plate for clean, low-slung single motor installation. E-Revo Brushless Edition includes Power Cell NiMH batteries for Ready-To-Race fun right out of the box, and is ready for your choice of Power Cell LiPos – no modifications needed.
This is one sexy drone. The red and carbon fiber make it look like a Ferrari. For an RTF at this price it comes with good components and appears that it would make a great starter drone. It's running 20amp Blheli Opto ESCs, a 600mw VTX, 700TVL f/2.8 IR blocked camera, an F3 flight controller and has 2205 2300kv brushless motors. So I have high hopes for it. I'll be getting it out for a first flight very soon. Specs are below.
- Premium carbon frame, strong and lightweight
- Powerful 2205 2300KV brushless motors, 20A OPTO BLHeli ESC
- F3 flight control system dedicated for high-performance flight
- 5.8G real-time FPV, 32-channel coverage, 600mW high power for flying farther
- 700TVL CCD camera with 115-degree FOV features good imaging effect at night
- Standard camera holder with vertically adjustable angle
- Bright multi-color LEDs with lampshade at the rear

How many planes can you count? Running out of room! More up above in the loft area too... Obsession or Sickness I'm not sure which one... Hey there's always room for one more... Wow!!! That's a nice one....
6 Axis gyro for more stable flight and ease of control
One key to return function: easy to find its way home
3D tumbling in four directions with 4 LED lights
4 Channel: ascend, descend, forward, backward, left sideward fly, right sideward fly and 3D rolling
Battery protection JJRC H20 With Headless Mode, unnecessary to adjust the position of aircraft before flying
Lightweight airframe with desirable durability
You asked for a Redcat RC and here one is. I didn't plan to get one this quickly, but I saw it on the shelf and couldn't help myself. The low price for the features helped make my decision of this over the Axial SMT Grave Digger. I plan to upgrade it to a brushless system and then re-work the RTR components to handle it.
