For review : Nitecore EC22

Product Page @ Nitecore

Nitecore EC22 provided for review by Nitecore

I was looking at flashlights one night ( as I some times do ) and I spied the Nitecore EC22 . Two things grabbed my attention right away , the first being the infinitely variable output and the second was the rotary dial . Never mind the 1000 lumen output or the fact that it it's all put in a very handy package powered by a 18650 or two CR123 . The very first thing I did on receiving the EC22 for review was to take it for a walk . Nope ! , I did not measure current or put it in the light box or anything else . I wanted to experience the EC22 first and then see what the numbers were . When I went for my walk I swung past a friends place and let him and his wife have a play with the EC22 . Now my friend took to the EC22 like a duck takes to water , without any prompts from me he had turned on the light and was adjusting the output . For a non flashaholic to simply use the light so easily tells me that the user interface is universally simple , kind of reminds me of a transistor radio with its rotary dial for on and of and volume control .

After visiting my friend I swung past the local park ( its a big park ) and the great thing is that the road / foot path is raised several meters above the park allowing some one with a flashlight a nice elevated position for shinning a light . For a light with small head and short reflector the EC22 did not...Continue Reading

At first I was getting a flashing red LED on Tx. I sent it to Mike(Dragonlink). It came back & now I get the solid green on Tx. I am now trying to bind to V2 Rx. I hold the bind button & power on the Tx. Yellow/orange light comes on, I release the bind button...rapid flashing yellow/orange LED. I power on the Rx and I get a solid red LED & a flashing green LED. I let sit like this for about a minute(Tx...flashing yellow. Rx....1 solid red LED & 1 flashing green). I power off the Tx. No changes to Rx LEDs. I cycle the Tx and Rx power. Still I have 1 solid red and 1 flashing green on Rx with NO blue light. Solid green LED on the Tx.

Is there a problem with the DL system or am I doing something wrong? Someone please help!!!🙏🙏🙏

Around 97-98, I bought an RTF from the local HobbyTown. I wanted it as a trainer for my boys, who were bracketing 10 at the time. For various reasons that didnít work out so I started flying it as a sport plane. I flew it as a pleasant break from the various and sundry higher performance planes that accompanied it to the field. I flew it a lot. A lot, 2 or 3 flights a trip to the field.

It started with a Thunder Tigre 0.40 engine and an Airtronics radio. I wore out that Thunder Tiger out and replaced it with an OS 46FX I had available. Woo Hoo! That was an exciting upgrade. I literally flew the covering off. Not figuratively, literally. It had that old sticky back covering that wasnít repairable. One flight led to a terrible buzzing, half the lower wing covering was in shreds. Not only that several hinges were broke. Completely removed with Monokote. Itís now on its third motor and third radio flight pack.

Got sick and tired of spending most of my time over in Vegas working, so I started looking for something better and by pure luck I landed my dream "retirement" job a couple months ago, flying a private jet out of Van Nuys, California pretty much just one day a week! That allows me to live at home in Lake Havasu full time, finally! And that means I have time to spend with the wife and on my hobbies. Can't wait to get the 5 models I have waiting in the garage built and flying!

Today is my 3rd outing with the SoloShot3. The 1st time around was a real failure as it was recording video when I thought it wasn't and vice versa.

The second outing was on 4/20 and I shot 4 videos that I condensed into 2. One long one that had all 4 combined with open sky footage removed and one more that used the take off and landing from the 4th video (medium framing) combined with video two that was shot in wide framing mode. The compilation is uploaded at 720 p60, the highligts at 1080 p60.

Hello all, I just picked up a habu 32! Iím very excited as this is my first composite jet and Iíve had a poor string of luck lately with my fw 90mm f16 (Bad aileron servo led to crash) . My habu 32 elevators are very strong, however the servos donít quite center after downstick, they are consistently down 1mm and will only go that far. When I give just a hint of upstick, they will center again as if nothing happened. Suggestions??

Our 1st & only view of the inside of the interstage. It probably would have cost a few thou from the BFR budget to put a roof on it or strip out all the guts, so Musk said forget it. They did strip out the pushrod that ejects the 2nd stage & hastily strung an extension cord to a warning light. The extension cord had a little left over. 2 wires in mid air appear to be additions. They could be a radio antenna used by someone else. What are the chances of retired Falcon 9's being sold as cell phone towers?

You can see everything mounted directly on the convex top of the LOX tank. Not content with plain old rods, they used horn shaped rods. It must be the most weight optimized way to transfer torque from a narrow diameter to a wide diameter.

There's a triangular enclosure which could only be a triple redundant brain box, where the 3 computers are mounted symmetrically. All the software flying the 1st stage & the IMU are probably in that box, all calibrated for its orientation on the LOX tank. We also see what could only be the nitrogen thruster tank & the pesky hydraulic fluid tank. Surprising such a small tank is all the nitrogen it takes to fly it back. There's no effort to balance it by mounting the tanks symmetrically.

The torque rods are already looking a bit rusted. The guy obviously doesn't know a 4k copy of the video is stored on the quad copter, but barely knows enough to hit send on an instagram app to upload low res telemetry.

I purchased a Mi drone and flew it for 2 minutes before it fell from the sky which distorted gimbal. I sent flight log to Xiaomi and they said the reason for the crash was that the battery disconnected. I am thinking about buying a new gimbal and securing battery so it doesnít disconnect again. Has anyone else experienced this problem?

This is review for the SJ-RG01 FPV goggle courtesy of HobbyCool. Initial thought is that it's a really nice goggle and not too heavy. I prefer box goggles over the FatShark type. I've tried FatShark Dom V3 and never could get it to fit just right. The RG01 is kinda in between and so far it has fit my face perfectly. I received the unit through Amazon and got it within a few days...

1. Price is just right at $79.90 from HobbyCool directly or $99.90 from Amazon.

2. Package comes with 2 rubber ducky antenna, charging cable (DC 6-28V), video/audio cable, nose foam and instruction manual.

3. The size of the goggle is between an Eachine VR600 and an Eachine EV800D. This has better fitment on my oblong face then either Eachine except for some very small light leakage in the nose area. This can be fix with the included foam.

It's been some time that I got that exited about some new "hardware"... but it's time to retire the OmniBusF4Pro as my goto iNav Flight Controller... it's not a bad one with it's onboard current sensor and osd... but the lack of "easy" 6 PWM outputs and not enough UARTs to get crazy... (BT+GPS+Mag+AirSpeed+vTx) kind of sad... that's why it's time for this new bad boy!

The new Matek F405-WING Flight Controller promises to give us (I think) everything you could ask for in a Wing FC
