QUADCOPTER FOOTBALL TARGET [4k] (4 min 1 sec)



Hi Football & Qaudcopter fans Chris aka Demondriver here I wanted to share with you an Idea I had to turn a Qaudcopter into a flying Football Target Hoop. I want to thank Brad & Vance for their help making this idea a reality.This Idea is for QB training and as a way to improve throwing accuracy of Quarterback for the NFL and College and HS Football programs.
I use a Chaotic brushless 3D Qaudcopter in this video
the Football hoop is made from screen door mesh
I chose to use Nerf footballs in order not to cause damage to the qaudcopter if we struck it.

If you need a vtx quick, this is a good option for $20 and free 2 day shipping, assuming you can live with 600mw.

Got all this parts doing nothing and decided to build another Y6. Weather been crazy here in California and I need something to fly that can at least fight the wind which is the norm over here lately making the minis useless. MTM @ 23.5 " and 16mm CF booms with Sunnysky X2212-13 and 25A Mantis BL Heli Esc's set up on a custom cut double stage Aluminum frame with 700 heli LG . Modified GF motor mounts to accept 2 motor set-up.

Here are some close-up pix....maiden video will follow soon.

A lot of people get dizzy after a long distance flying, and they have no time to take off goggles because they just focus on throwing up. A large amounts of goggles in the market work not very well, you can just stare into the snowy screen that like old black-and-white television. Wide-angle lens are adopted by many merchants, so image distortion is common. Anyway, AKK technology comes to change this situation, its antenna can process signal better, which can avoid those unstable and annoying snowflake point on screen.

Yeah, don't want to hear about it, but will push their views on everyone else. Typical.

Hi All, I recently decided to revive an old Saito Family 120 and the aircraft it was in. The engine was very dirty but had no physical damage. After cleaning and stripping I rebuilt the engine with new ntn bearings using a fully sealed one in the front with the rear seal removed. I managed to find a new piston ring and valves as well. I was unable to find a gasket set so had to cut my own. The needle valve was not in great condition but works. The exhaust had no silencer just a straight pipe and was a bit loud.
I did a bench run of the engine and it runs just fine.
I then decided to fit a new needle valve but could not find one so I bought one for a later 120.
I did not want the needle valve to stick through the top of the fuselage and wanted a remote needle valve but had no luck with that either. I then decided to make my own the only problem was finding a fuel fitting for the carb (5mm x 0.5mm pitch) so made my own parts on my mini lathe.
I have again run the engine with my remote needle valve and it works just great. I also then made a velocity stack and removed the choke at the same time and on the bench run got 9330rpm on an APC 15 x 8. I have subsequently also made my own silencer but have not test run with it yet. Silencer was also an issue with the thread size or 14 mm x 1mm pitch so had to cut my own. I will post some pictures of the work I did. Any questions welcome.
Fly safe
Charlie.

Hello everyone,
I have been building the Dumas Trojan F-31 Cruiser and need help. I do not know what type of paint and what company to paint it. I have read through a few forums and found that people prefer to use a primer to help the paint stick then appliance paint or auto body paint to cover a boat. I really don't know what to use for this specific model. Here is a link if it helps: http://www3.towerhobbies.com/cgi-bin...P?I=LXE349&P=0


I am also in doubt about what motor, speed control, and remote to use for the boat.



If I could have some help that would be wonderful!!

The day had finally come to install short circuiting switches on the Mastech. Many circuits were fried because its current limiting was set too high. It was too much trouble to unplug the circuit & plug in a short circuiting wire to set it.


Despite looking simple from outside, the front panel is packed on the inside. There was only 1 place to squeeze the switches in. The LEDs had to be sandwiched between the switches & the plastic. At this time, another desire emerged to have switches for turning off the individual outputs without turning off the manes, but this would have been a much more incremental benefit than the short circuit switches.


With it all installed twice, the switches pointed at the current dial when they were shorting & pointed at the voltage dial when they were open. This was the most intuitive orientation. They worked very briefly, at low voltages & all current up to 5A. When the voltage was set to 30V, the switches quickly failed closed.


The switches open by a spring force which the human has no control over. The human can merely press the spring to make contact, but the spring must break contact by its own force. The spring had arc welded to the contact. It could be broken apart & reassembled, for the most part. Despite being rated for 6A 120V, the switches still failed at 30V 5A.


The best the internet can come up with is 120V AC ratings being equivalent to 14V DC, because in AC there is a zero crossing after 8ms to break the arc while in DC, the arc can continue. While the power supply limits current when quiescent, there is a very high inrush current when short circuiting it. The Chinese must have encountered the same problem, said "f*ck it" in Chinese & left out the short circuit switches.

The lion kingdom long dreamed of a switch allowing a heat gun to blow cold air. It would cool hot glue. The deed was finally done. The wires were not intuitive. The big red & black pair didn't power the heating element, but probably powered the thermocouple. It was the tiny black pair connected to CON1.

Unfortunately, it takes a very long time for the heating element to cool off. The switch has to be off when it 1st comes on or it'll take 30 minutes to blow cold air. It does indeed cool hot glue.

Always liked the look of the Atom V2 but not the price and some reports of ESC fires. Also the camera on the V2 was not customers first choice and many just complained or replaced them.

So why not just build your own I thought.

I started off I started with a budget of around $200 because I don't think a 130 sized copter should be more than that.

My choices for the build were the following

1. EMAX 1306 4k motors for $48 https://www.banggood.com/Emax-RS1306...p-1060943.html


2. Racestar 4in1 20A ESC $23 https://www.banggood.com/Racerstar-R...l?rmmds=search


3. Genuine HGLTECH (careful of knockoffs!!!) F3 V4 Flight Control Board AIO 25mW 200mW 600mW Switchable Transmitter OSD BEC PDB Current Sensor $42 https://www.banggood.com/F3-V4-Fligh...l?rmmds=search
