Status: offline 		Yes that is very cool tend2it. So I guess the air created by that ducted fan passes over that curved surface and creates lift. I don't think those things would fly very well in any siginificant wind though.

It also launches something called a HUNTIR (High Altitude Unit Navigated Tactical Imaging Round) round which deploys a video pod with a parachute and wireless downlink to a height of around 700 ft. It was featured on a Discovery Channel show called Future Weapons.

Status: offline 		I took the T-Rex up for a little hover practice for the first time. I have to agree with Lacey, the 600 is awesome! After some slight trimming, it would sit in a 4' hover without any input control at all. It's more stable than the DF with the Ti on. It was a little nerve-wracking lifting off the first time, but immediately I realized it's just rock solid and it isn't going to do anything unexpected. I had RC & Me set it up so for maximum stability for AP work, and it has longer, weighted flybars. There's no D/R or Expo settings needed, and it's rock solid. I tell you if you've never flown a ship like this it is an amazing experience. It weighs 6.6 lbs, the 4' rotor roars and the BL motor screams - I'm hooked! I figure it should be able to lift 2 lbs pretty easily.

The Eyeball Cam is pretty amazing. They can roll it down a hall or into a room and it rights itself. You can invert the image if you use it upside down. It has pan and zoom, but no tilt.

Status: offline 		I have seen that before either on Tactical to Practical on the History Channel or Future Weapons on Discovery. They just tossed that ball into a room or down some stairs and the self level circuit corrected the image. I guess you could just mount the ball to a small tilt platform with a tlit servo to get your tilt function on the helo. How much does it weigh? I couldn't find the weight on that site.

Status: offline 		It weighs about a pound - it's extremely rugged and a bit daunting to watch them throw it down a hallway or into a room, considering the amount of electronics and optics inside. It's heavier on the bottom and unless it gets jammed against something, it always ends up sitting upright on its base. They also attach it to a pole for looking into attics or on a rope for lowering down stairwells, etc.

BTW the demo today went great. Looks like hopefully we're still on track for the training program. We're thinking that two platforms -the SAVS and the T-Rex - should just about cover all our requirements.

I operate my own breaking news video website in my area and below is the version that is available on my site with more shots than CNN and Univision used. It also has interviews with the officer that caught the crane falling from his dash camera and two other eyewitness interviews that CNN didn't use.

Those guys like to invent new moves with names like the tic-toc, chaos, hurricane, etc. If I tried that I could add my own maneuver called "the auger".

Status: offline 		Here are some pics of the AskmanAP pan/tilt .50-size camera mount on the T-REX 600. The extra weight is going to take some getting used to, but I flew it again today and it seems the 600 doesn't have much trouble handling it. Of course there's no cameras installed yet. The main thing is you have to be really careful not to build up too much momentum in a descent. Still, I think this is kind of overkill - more suited for the Maxi-Joker with a 6' rotor. This unit is operated by a separate Rx/Tx system and an operator using a monitor or video goggles. I'm also going to fab a simple mount with a 30 degree down tilt, and shoot some pics & videos.

I'm still experimenting with the best approach to night orientation. Pic #3: I replaced the stock 600 7.4v 1100 mAh 2S receiver battery with a 2100 mAh (silver battery on the bottom). This battery also drives 4 high intensity LEDs, 2 blue facing forward, 2 red facing aft, mounted on the black aluminum crossbar behind the forward skid support. The upper 1300 mAh 11.1v 3S battery drives the black high voltage inverter mounted on the vertical member, which powers the port/starboard glow wires attached to the "faux wings". I'm really having a hard time finding a set of 600mm lighted blades - everybody seems to be out of stock.

Pic #4 shows a .05 Lux video camera from Range Video.

Pic #5 shows a 900 MHz transmitter/receiver system that will not interfere with the 2.4 GHz Spektrum Rx/Tx (also from Range Video).

Pic #6 shows a Bergen helicopter set up for very high AP flights. This is discussed in This Thread.

Ciao,
Bruce

Status: offline 		BB_DF, I would put a 5 LED array facing forward on each wing tip and a nose array which would make a huge amount of difference with orientation. That's the only way I've been able to fly the DF 100 yards away longitudinally at night and bring it back because all you can see are the lights. When all of the LEDS are facing you head on, there's no doubt that you're nose in.

Yes, I've come to the same conclusion. I call them my "come home to Daddy lights". The red lights facing backwards are sort of a warning indication to avoid fly-aways.

Status: offline 		Here's some raw pop-up video shot with my old Canon PowerShot A80 (4 MegaPixel) camera and the AskmanAP mount. There's a roll compensator that adjusts for the side tilt during a hover, and you can see it swinging on the descent. I'm still adjusting to the extra weight and weird handling characteristics of all the extra hardware hanging below the skids. I ordered the AP-2000i stabilizer today and I'm sure it will help with the smoothness, plus getting a good camera - lighter with a better lens and built-in de-shake.

Status: offline 		Here's a simple up-and-down shot with the Canon A80. I'm going to get the Panasonic DMC-FX07 this week and it should help a lot with the movement. I've also ordered the AP-2000i stabilizer system. Sorry about the length, the old camera's .avi format won't allow me to edit with Movie Maker.

http://www.youtube.com/watch?v=UMdkdrijpDk

Here's an emergency landing due to the battery going dead! Notice how the ESC tries to warn you. It's hard enough to descend with all that extra weight, so I'm pretty pleased with the landing, all things considered. My neighbor had no clue what had just happened. The battery was so overdischarged the charger thought it was a 5S instead of a 6S. I've ordered a set of semi-symmetrical blades that allow a hover at much lower throttle settings with the added weight and longer flight times (so long as you don't want to shoot your videos inverted!), .

Status: offline 		Here are a couple of stabilization systems using the same technology as the DF. The first two pictures are a small 3-D helicopter on which I have installed the FMA Direct Co-Pilot CPD4. This was a proof-of-concept test to evaluate how well the system works. Picture #1 is the IR sensor, same as on the DF. The Falcon is a non-CCPM design and you can see in picture #2 there is a wire controlled by a separate servo that runs up the center of the main shaft, controlling collective pitch on the swashplate through a slot in the shaft. The CPD4 will work on airplanes and non-CCPM helis; FMA Direct is working on a newer system for CCPM designs, but it has not been released yet. The results - super stability for such a small heli.

Picture #3 is the Spartan-RC AP2000i controller, which works with all know swashplate mixing schemes and radio types. FMA Direct owns the patent for the leveling technology, so DFI and Spartan-RC license the designs from FMA. Notice in pic #4 the same FMA sensor is used. The AP2000i has been around for 4 or 5 years now, and the technology is pretty reliable. One nice feature is it displays the number of glitches and bad frames during a flight, and also the current and lowest Rx battery levels under load. This could give you invaluable data if you're testing a 2.4GHz downlink with your 2.4GHz Spektrum or FASST Rx, and want to see if they're interfering with each other. The AP2000i is also set up to interface with an altimeter to show highest altitude, and also 2-axis gyros for further stability.

The calibration and operation of these units is quite different. On the CPD4, you hold the heli sideways and press the cal button. When you release it, one of the servos starts to tick off a count between 1 and 10, indicating the calibration strength. I would typically get an 8. This is equivalent to the two green LEDs on the DF, but obviously more precise. Then the swashplate gyros begin to oscillate in a slow continuous motion. Then level is set similar to the DF and you're ready to go. You only need to calibrate and level once, unless the weather conditions change drastically, or you move from say, Bogota to Reykjavik.

The AP2000i is calibrated internally and doesn't have to be re-calibrated unless you feel it's needed. Then you can either calibrate the earth/sky gain, or the level, but they can be done separately. Of course there are many other adjustments that are programmable, such as response rates, etc. I fly the AP2000i on about 50% authority, switched on after it's high enough to see over the local thermal clutter. Anything above about 70% and I find it difficult to overcome the device's control. Instead of just setting the expos on the Tx, the DF would probably be well served by a %control adjustment on the spare channel, or a potentiometer on the controller. Mike Dammar said he had put a remote gain control on the DF and it was a disaster, but that's a lot different than a %control adjustment.

A practical note on flying your DF with Ti on in the wind. Sometimes it suddenly doesn't seem to have the guts to fly back to you. Turn it 90 degrees and fly it sideways, or fly it backwards towards you. A lot of times what's happening is you set the level with the nose away from you, and when you turn it around to fly back it could be bucking the Ti level. I've found that invariably it will fly better with one of the other rotors leading. This is worth practicing when conditions are favorable, so you'll feel comfortable with the maneuver when things are a bit more critical.
