!Introduction

The MQ-1 Predator is an unmanned aerial vehicle (UAV) which the U.S. Air Force describes as a MALE (medium-altitude, long-endurance) UAV system. It can serve in a reconnaissance role, and it can also be weaponized and can carry and use two AGM-114 Hellfire antitank missiles. The aircraft has been in use since 1995, and been in combat over Afghanistan, Bosnia, Serbia, Iraq, and Yemen.

Hobby Lobby's Art Tech Predator UAV is a fast building, scale-looking aircraft that's a great way to get started in the world of aerial photography!

!Kit Contents

The review package shipped from <a href="http://www.hobby-lobby.com/index.htm/">Hobby Lobby</a> and it arrived double-boxed and free of damage. Everything was secured inside the box and was well protected. The Predator UAV has a very low parts count and there are only a few assembly steps required to get the plane airborne. A small Philips head screwdriver and a pair of pliers are needed to complete the assembly.

*Kit includes:
*Fuselage with pre-installed speed 400 motor
*Removable wing panels with pre-mounted wing spars
*Hardware package
*Heavy duty main landing gear and wheels
*4-channel 72 mhz transmitter with pre-installed 6 channel receiver
*Assembly guide and instructions

*Kit requires:
*Eight AA-type batteries for the transmitter, and one AAA (included) for the digital camera.
*Phillips head screwdriver and pliers

!Assembly

The instructions are photo-illustrated, and the manual is easy to understand and follow. The written portion of the instructions have a few language errors but nothing major, and the photo-illustrations are a plus. All the assembly steps could be completed at the field with just a small Philips head screwdriver and a pair of pliers.

!!Wing

The two wing panels attach to the fuselage with four screws and a plastic cover plate. No gluing was required in this step.

!!Fuselage

The spring-loaded nose wheel comes already attached to the fuselage. The main landing gear is held in place with two nylon bolts that insert into the plastic wing cover plate, then bolt onto the fuselage.

@Pred-6.jpg: The landing gear attaches with 2 nylon bolts.

!!!Tail assembly

The tail assembly is attached to the fuselage with six screws. During the assembly, I noticed that a couple of the small plastic plates that hold each screw in place were not glued down completely, so I re-glued them with contact cement and waited a few minutes for them to dry before continuing. Last, I attached the adjustable clevises to the preinstalled control horns. There were several holes in each horn, which made adjusting the amount of control throw easy.

@Pred-14.jpg: The tail assembly with adjustable clevises.

!!!Motor, ESC and battery

The included 110V NiMH charger is a wall-type, and charging the 1000mAh battery took a little less than 2 hours. I highly recommend charging the battery the day before flying, then 'topping it off' just before each flight. A 'quick charger' and additional batteries are available from <a href="http://www.hobby-lobby.com/index.htm/">Hobby Lobby USA</a>.

!!Finish

After 'warming up' the NiMH battery, I installed it in the pre-molded battery compartment in the nose of the fuselage. The digital camera was installed in the middle of the fuselage and a wire from the camera plugged into the receiver. The camera’s lens aims down through a small hole in the underside of the fuselage. The camera is operated by two small buttons; one serves as the power button and the other enables erasing of the camera's onboard memory after pictures are downloaded to a PC.

!Flying

The CG location wasn't mentioned in the instruction manual, but the Predator balanced right on the wing spar so I assumed this was already worked out by the manufacturer. The molded battery bay did not allow any fore or aft movement of the battery.

After the NiMH battery was installed, the tiny digital camera was 'powered up' and ready to take pictures. The plastic nose cover is held in place with a magnet and small screw. The maiden flight was made on an unusually calm summer morning. The Predator UAV needed a fair amount of space for takeoffs and landings, so at least a large park or ball field is recommended for the first flight. The Predator can also be launched with a firm hand-toss.

!!Basics

The speed 400 motor provided good power. The Predator flew well at 3/4 throttle but full power was needed to gain altitude.

With its 52 1/4” wingspan, the Predator is difficult to stall, but can lose altitude fairly quickly when power is decreased.

Loops were smooth and large, and the wings flexed a little during each loop. The flat carbon strip inside the wing panels allows for some flex, though. The elevator was effective, especially after we adjusted the clevises to allow for more throw.

!!Take Off and Landing
The Predator UAV's stock brushed speed 400 pusher motor and 8 cell NiMH battery provides more than enough power for takeoff from a paved surface, but my club field is grass so we opted for a hand launch. After full throttle was applied, a short running toss was all that was needed to get the Predator in the air.

With an all-up weight of only 22 oz, the Predator still needs a little power to make a smooth landing, but the big wing makes it very stable and controllable.

!!!The Mini Digital Camera
Although it's tiny, the Predator UAV's onboard digital camera will take up to 26 shots per flight and is easy to operate via the rudder stick on the radio by simply moving it all the way to the left or right and holding it for a couple of seconds. There is also an Auto mode that takes one photo about every 30 seconds if the rudder stick isn't used. The included PC software and USB cable make downloading photos after each flight a snap! There was no information as to the camera's resolution, but I'd estimate it to be one mega pixel or less.

As with all forms of photography, adequate lighting is the key to good aerial photography. The Predator UAV's still photos were taken over a couple of unusually calm sunny days here in Texas. To get the best performance out of the Predator's onboard camera, a bright, sunny day is essential and a light wind to slow the plane down a bit would also be a big plus. The sample photographs we took with the Predator were pretty decent, but a little wind would have helped slow the Predator down and make the photographs a little less blurry. These shots were taken after we had received record rainfall over a period of several weeks in north Texas.

!!Is this plane for a beginner?
The Predator is a 3-channel plane with v-tail mixing and is not difficult to fly. It is not, however, a slow flier and requires some 3-channel experience on the sticks. But if you've thought about getting into the exciting world of aerial photography, the Predator UAV's smooth flying characteristics, cool looks and complete onboard camera system make it an excellent choice!

Given that this post is for UAVs and not typically R/C airlanes...who is going to be the first to put a small autopilot in this model? :rolleyes:

Those wings do a fair amount of flex to them. Thought it was an ornithopter for a minute. Flap flap flap.

Nice review by the way.

I like it! FPV and/or PicoPilot would be killer. Does anyone make a larger Predator that would handle Picopilot, Inspire OSD, Geko 201, Pandora Pan and tilt? I now am putting all this on a Twinstar 2.

The manual pictured in the review has '300k pixels' on the cover.

640 * 480 = 307200

307200 / 1024 = 300k (exactly)

Just a guess though ... could be 600 x 512, 1024 x 300, 612x502 ...

The picture quality of the sample photos is so poor, I don't know why anyone would bother using that camera. I have had very impressive results using an Aiptec camera hauled into the air by a Slowstick. It may not look as cool, but the photography is far better, all at a reasonable price. ;)

Thanks for the excellent review. I ordered one from Hobby-Lobby and the box arrived free of damage. During assembly, I also noticed some problems with the tail. One of the six screws was glued into the mount and another screw was broken off half way into the mount. I believe that I have it secure, but a test flight will tell the tale. I also noticed that the main wing did not line up well during assembly. It appeared that the predrilled holes were off about a quarter inch. Hopefully, this will not impact flight much. I will post the results of the test flight when completed. Just waiting for some good weather.

Well, had a nice weather break at lunch so I decided to give it a try. Calm, partly cloudy, so we opted for a hand launch which was successful. However, immediately after the launch an issue was encountered with a severe right turn even at full left and left trim. Aircraft made an uncontrolled decent into a fixed plane (the ground). Upon further inspection, the issue with securing the tail may have a greater impact than previously considered. Gave the guys at Hobby-Lobby a call. They are great and are interested in helping with resolving the problem. Hopefully, I’ll be able to report a more successful result in the next week or two.

To me the wing may need some type support.other then the flat carbon spar when landing in grass in the vid looks like the main wing got a good jolt wonder how long it will last
And a ?? if useing say a black top run way will the battery run down faster sence the camera and servo-s plus receiver are runing and needing a long distance to take off and land how long will the battery last before charging say 10 minutes or ????

Is the tail on this larger Predator is the wrong way around; it should point downwards, not upwards? That, in combination with the air inlet on top of the tail makes it look more like a MQ-9 Reaper (http://en.wikipedia.org/wiki/MQ-9_Reaper).

This plane has too much dihedral in the wings. It sort of reminds me of a pigeon coming in for a landing...haha

They really need to stiffen up the spar to keep it from flexing... it loses the Predator look when it does that.

Yes, I saw that a few days ago. If you look about five pictures down you will see:

The tail is swept down because the emergency landing parachute deploys from the bottom of the aircraft causing it to land upside-down. This inverted crash landing protects expensive optics and, because the tail is swept down, does not damage the tail.

Right next to a picture that quite clearly shows the model in a conventional V-tail arrangement.

I did wonder if it was assembled incorrectly but I don't think there would be sufficient ground clearance unless the angle could be reduced.

Okay, I received a replacement in the mail today from Hobby-Lobby but there are clearly issues with the tail assembly. There are six screws that attach the tail to the fuselage but four of them were incorrectly mounted and two were glued in. It was impossible to remove one of the screws and it had to be pried from the fuselage. Unfortunately, it is necessary to unscrew the tail assembly to complete the build. :(

Additionally, the six mounts on the fuselage were not correctly aligned. For a RTF model, it seems to require a bit more customization than I would have thought to be able to assemble properly. I will try to post some pics to illustrate the point.

While Hobby-Lobby has done a good job in trying to help resolve these issues, the quality of the product just doesn’t seem to be up to par. It appears to be more of aquality control issue at the manufacturer level.

For the price, I wasn’t expecting perfection, but I was expecting to be able to assemble and fly it. For now, I will need to consider my options before attempting to put it in the air. If you choose to purchase one, be sure that you carefully inspect the tail assembly before flying and be prepared to make modifications when putting it together.

Gday All...
Just wondering, how high does the Predator fly and what is its range?
im still a newbie, but how will i know if its out of range, and what do i do?
Im a PPL in the real world. im sure R/C is much different?
Also is it possible to buy a Picture receiver? That way i dont have to wait and put it on the Computer? like can i hook it on or something?

Please, tell me tell me!

hope to hear from you guys soon!

Cheers :)

has anybody attatched a flycamone to their HL Predator? where's the best place?

I'm waiting (like everyone else I guess) for my flycamone2 from HL.

I lost my other 2 ones on
Supercub flyaways :(

I had the predator and it was a nice flying airplane. I bounced it off a rooftop, glued it back together and it flew again. The dihedral was welcome because of the lack of ailerons. If I didn't crash it a second time I would definatly want to straighten that wing out and put some ailerons on it.

BTW, I am waiting for this camera instead of flycam2:

Well, finally had some good weather and some time today so I figured it was long overdue for another flight. I took some precautions with this flight and added some packing tape to the leading edge of the wing as well as a carbon fiber rod to the leading edge of the lower tail assembly. I opted to not secure it with the provided screws but to build up the connection point and have it fit snuggly so that on landing, it wouldn't break anything off. I also beefed up the nose with two carbon fiber rods as a hard landing seems to break the nose off as the battery is all the way forward.

One big change was that I added a carbon rod through the entire wing . This added a lot of strength and also cut down on a lot of the 'flap' (see photo).

Take off was real easy (see photo) and it flew pretty well. A little sluggish when responding to control inputs, but this can probably be corrected by moving the control rods down the horns a little to get more throw. Had some porposing after backing off the throttle, so I may just need to adjust the CG forward a bit. Overall, a much better experience than the first attempt.
:)
