After loosing my Aegean v2 I was really bummed because I like to tinker with stuff, and the Aegean was a perfect platform for that! So when I saw the Pioneer E350 over at Banggood I immediately ordered one because it looked great, had the same tinkering potential as the Aegean, but it was 100 USD cheaper!!!
      When it arrived the surprises just kept on coming! In addition to looking simply amazing, the quality of the plastic was definitely better than what I expected, and the copter looked much better in person than on the product listing photos. In addition it also flew very well out of box, needing only a quick compass calibration. This is truly what I would call a RTF package, and when you also get the gimbal for it and a compatible camera you will have a truly amazing aerial video platform for less than 400 USD! That is hard to beat! This machine is absolutely worth every cent.

ARRIVAL STATE

      Well... the copter arrived via DHL in 3 days from China in perfect condition... so not much to say here! I was surprised at high neatly this thing was packed, and even though it is the same size as the Aegean v2 and even has a larger radio the box it came in was noticeably smaller in volume!

WHAT I LIKE

      Right, so first thing was the small size of the box. It does take just a few minutes more to assemble it and get to flying, so if you are one of the more patient out there it would be more than OK to disassemble the legs each time to store it back in the original box for easy transport.
      And speaking of the legs, they are in fact removable via a set of thumb screws that are easy to access. In addition there are no antennas or compasses mounted on them, so this makes the copter really easy and quick to break down a very compact state.

      Also featured on the bottom of the frame are a set of connectors. The Micro USB port allows you to connect the flight controller, which is an APM, to your computer for all sorts of calibrations and setting adjustments, if such are ever needed. Luckily there is a way to calibrate the compass without connecting it to a computer, so you can do it on the go.
      The 5 pin connector on the left is for the optional telemetry module, which I definitely recommend people to purchase along with the copter, or if you are already an APM user and have one of those telemetry kits, you can plug it there and use it. I would just urge you to open the frame and verify the wiring so you don't burn out something!
      The 3 pin connector to the right of the 5 pin one is for the gimbal control. It allows you to control gimbal pitch and roll via two of the channels from the radio receiver.
      And the two larger 2 pin connectors on the bottom provide power for the gimbal and a video transmitter.

      The copter comes along with all of the necessary cables for those connectors so you will not have to chop and solder to make your own cables.


Eachine Pioneer E350 - a really GOOD quadcopter!

      It is worth mentioning that with the copter you also get the standard set of stuff for this type of copter - a 2200mah 3S 25C battery pack, a charger, a data cable for connecting the flight controller to the computer, a set of hex head bolts and a hex wrench for mounting the optional gimbal, and a user manual, which is not in the photo but is surprisingly understandable for one coming from China!

      And now tell me if this isn't the most badass charger you've seen? Its not every day that you can have Batman charging your batteries! And at 2.1 charging current and an option to charge 3 types of batteries this is by far the fastest and most sophisticated charger I've gotten with a RTF kit. Not to mention the best looking, just like the Pioneer itself!

      Moving back to the copter, its always nice to see metal threaded inserts into the frame to allow for mounting of additional gear, be it a gimbal or something else! Makes the whole ordeal a lot easier and quicker.

      The underside of the motors features LED lights - blue at the back and red at the front. The blue LEDs are indicating the GPS status, while the red LEDs are indicating the battery status - when the battery gets low they will start to blink, so keep an eye out for that as you will not hear an audible indication of that.

      And so we come to the motors. They are 2212 size at 920Kv, and not 980Kv like Banggood's product listing states, although this is based purely on information from the manual, the motors themselves have no markings on them. They should be 920Kv as this is the most popular spec for copters of this size, and after a flight come down cool as ice, so definitely not 980Kv. Also the motors come with threaded prop adapters, which makes installation of the self-tightening propellers very easy, and also makes them compatible with DJI Phantom 3 propellers, and there are some pretty cheap prop options from China.

      The "eyes" of the copter at the front are also indicating the copter GPS status, so while on the ground you can use them to judge whether it has achieved GPS lock or not. Keep in mind that the GPS may not achieve a reliable lock until you calibrate the compass when you receive the copter, so make sure you do it before the first flight.

      Another thing that I also like about this model, in addition to the good looks, is the material the top part of the frame is made of. It looks and feels rubberized, and is very smooth and nice to the touch. Definitely feels much more expensive than it is!


Eachine Pioneer E350 - a really GOOD quadcopter!

      I also like the fact that the frame is very stiff! I can barely twist the arms at the motors, and that is a prerequisite for a good platform and stable flight.

      And adding to the looks of the copter is the shark-like tail fin at the back! This is a marvellous design piece for me and it would have been soo cool if they had installed some sort of an antenna in there! As of this moment I don't think there is an antenna in there... but sometimes in the future I might think of something.


Eachine Pioneer E350 - a really GOOD quadcopter!

      The copter also comes equipped with a standard XT60 connector, which makes it easily compatible with most 2200-3600mAh 3S batteries out there.

      And now we come to the landing gear. The Pioneer is actually 20mm taller than the Aegean v2 was, which means more ground clearance for the gimbal, which means that a 3-axis gimbal will fit with room to spare.

      And speaking of the gimbal, it is not anything spectacular at a first glance, but the non-metal parts do appear to be actual carbon, the flight controller is small and light, the wiring is tidy, and the wires are very soft and bendy and are wired through the structure of the gimbal so the whole thing looks very clean, and last but certainly not least it works VERY well.... and my FireFly 6S fits in it perfectly.

      And finally we get to the radio. Its not as good looking as the Aegean one, but it is an 8 channel radio and you are able to use up to 5 flight modes and controll both gimbal axis.

      The radio takes 4x AA NiMh batteries, which makes it very easy to get everything going, and not have to charge one additional battery for it. You just go to the store and buy a pack of AA batteries and off you go.


Eachine Pioneer E350 - a really GOOD quadcopter!

      I like the top gimbal plate because it has proper mounting holes at a few locations and this allows us to mount the gimbal either more to the inside of the frame, or more to the outside. This allows us to adjust the CG in case a heavier battery is used and keep the craft well balanced. Moving the gimbal forward will also allow the camera to see less props and arms during flight.


Eachine Pioneer E350 - a really GOOD quadcopter!


WHAT I DON'T LIKE

      As with other models... this one is not absolutely perfect, so this is what I don't like.
      First and foremost, for some reason the designers have decided that the arms need to arch down from the body of the copter rather than level or up. The copter looks very good, but those down arching arms actually do enter into view of the camera more easily, especially if the camera is not angled a bit downward. I will have to see if they will get into view when the camera is facing down rather than straight forward, but in any case it would have been better if the arms were going up, or at least straight and level.


Eachine Pioneer E350 - a really GOOD quadcopter!

      Opening the battery hatch you can see some sort of grey/silvery tape on the top of the inside of the frame, so this is probably covering the GPS unit. You will also notice that it is not in the middle of the frame and also that it is definitely NOT at the highest point of the frame, and also very near the battery power wires. This last thing will not be an issue if this piece of tape is lined with copper tape to shield the GPS from interference, but from the look of it and its thickness I doubt that.


Eachine Pioneer E350 - a really GOOD quadcopter!

      Following the loss of the Aegean due to battery hatch opening in flight I am very uneasy with the way this lock operates and I definitely see the potential for something similar to happen here, however this can be easily solved by adding some velcro to tape over the hatch when the battery is in there for additional security.

      There is also a small issue with the labelling on the radio. At least on my unit the pot labelled for gimbal pitch actually controlls the gimbal roll and the one labelled gimbal roll controls the gimbal pitch.

      I am going to mention the radio battery situation in this section as well. I appreciate the convenience of using AA batteries, but it would have been nice if they could make it a removable battery tray that could be replaced with a NiMh battery pack, or a LiPo pack to last much longer.


Eachine Pioneer E350 - a really GOOD quadcopter!

      And last, and this is more of a nuissance rather than a real issue, the provided cables for powering and control of the gimbal are way too long and when connected as they are it creates a bit of a wiring mess at the back of the copter. This can probably be remedied by a piece of tape, but in my view this is only half a solution... and it will get worse when you add in the telemetry connector and the video power lead.
      When I add those in I will definitely redo all the leads so they will be the proper length and look as clean as possible.


Eachine Pioneer E350 - a really GOOD quadcopter!



THE VERDICT


      Alright, so half the issues with this model are actually more of a nuissance rather than anything more serious and can be easily addressed and solved. The only real issue is the low hanging arms, but again you can mount the gimbal further forward and point the camera slightly downward, which will prevent the amrs from getting into view. This will also allow you to use a larger battery for extended flight times and still keep the copter balanced.
      Considering the good about this copter really makes it very desireable. The plastic is very nice, the look of the copter is impressive and memorable, it is able to achieve around 10-11 mins of flight time with the provided battery and the gimbal and camera mounted, it is very stable in flight and quite fast when it needs to be. Furthermore, if any part of the electronics is damaged it can be easily replaced because the flight controller, GPS, compass, ESCs and power distribution board are separate modules. This also allows for easy upgrades should the need or desire arise. I also need to mention that fact that there were no vibrations on the video straight out of the box without any prop or motor balancing, which is quite impressive at this price point.
      And I can't ignore the price either! This is actually one of the stunning things about this machine, it costs less than 200 USD, and add to that around 80 USD for the gimbal and very little for shipping and you have an amazing aerial video platform for less than 300 USD. The FireFly 6S camera fits the gimbal perfectly just in case you don't have a GoPro already, so in the worst case scenario you will shell out another 80 USD for a camera, although there are also cheaper models of this size and form. So, that puts you are less than 400 USD for an amazing copter with a gimbal and an HD camera, that also flies good, has RTH and position hold functions, and for just a little more you can add a video system to that. You just can't beat that package!
      I can't wait to open this up and see what could be tweaked to make it even better, and I can definitely say that this marvellous machine is ABSOLUTELY worth the money!
      See for yourself... and I haven't even balanced motors and props yet:






ASSEMBLY AND MAIDEN



      There is not much assembly for this model, you just have to mount the legs with the provided thumb screws to the main body... and you're ready for flight.


Eachine Pioneer E350 - a really GOOD quadcopter!

      As a rule of thumb it is a good idea to fly the copter first without anything additionally mounted to it. Just in case there is something wrong with the copter you definitely do not want to crash with the gimbal and camera mounted to it. So, always do a few flights without an additional payload to make sure the copter is flying well and everything is working.
      Also, before the maiden flight READ the user manual and do the compass calibration, otherwise you may experience issues with the Loiter and RTH flight modes.
      After you have flown a few batteries and gotten used to the way the Pioneer flies, you can now install the gimbal. I chose to mount it using holes that would put the gimbal more on the inside of the frame because for the time being I will be using the stock battery.


Eachine Pioneer E350 - a really GOOD quadcopter!

      As the dampers are quite stiff you can use a screwdriver to gently inser them in the holes on the other gimbal plate and assemble the unit.


Eachine Pioneer E350 - a really GOOD quadcopter!

      Then just use the cables provided with the copter for the gimbal and connect everything up. When you plug in the flight battery do not touch or move the copter for 15-20 seconds so the flight controller and gimbal can properly initialilze.

      Here is the video review and maiden flight, just in case you missed it in the "VERDICT" section above:



      With a little luck there is much more to come so stay tuned. This weekend I am planning to test the max range of the radio, adjust the voltage settings on the power module, and mount a video Tx so I can finally get some FPV flights in.
