For my first custom FPV quadcopter, I chose to purchase the GEPRC’s GEP210. It is a 210mm quadcopter frame designed for FPV racing. I purchased mine from banggood.com for $39.89. It was shipped from the International warehouse and took 10 days to get to me here in Maryland. Not too shabby!
In this review, I will cover what comes in the box, I’ll take some measurements of the parts and frame for you, and we’ll put it together with what comes in the box. Lastly, I will cover my first impressions on what I find good about the frame and what I do not like.
What’s in the box
In the box you will find:
- A single sheet assembly instructions
- Main frame
- Bottom plate
- Side bottom plates
- Side plates for the camera mount
- Camera mount
- Top plate for the action cam
- Back LED plate and power wire
- XT60 connector with power cord
- Power distribution board
- Zip ties
- All the screws and bolts
The main frame is carbon fiber and is 3 mm thick. All the holes and slots seem to be nicely machined and none seem off shape. The frame feels very sturdy.
The frame is a true 210 mm frame.
A few other measurements:
- Left to right motor to motor front: 165 mm
- Left to right front wing to wing: 195 mm
- Left to right motor to motor back: 165 mm
- Left to right back wing to wing: 195 mm
- Front to back motor to motor: 131 mm
- Front to back wing to wing: 160 mm
- Total front to back length: 185 mm
All the other carbon pieces, on the GEP210, are 2 mm thick.
The PDB provides you with nice big pads to solder your ESCs to, but are located on each side. ThiS may make the installation challenging with the side plates. It does provide you with both a 5 volt output for the FC and a 12 volt output for your FPV camera. It weighs 5.9 grams.
The camera mount is very small and does not seem to offer great ability to attach a camera to it. Most FPV cameras come with holes in each corner and this does not. It is adjustable on the angle, however, up to a 45 degree angle. It is 30 mm x 30 mm in size. It weighs 4 grams.
The LED plate, for the back of the GEP210 quad, offers you 6 ws2812 LEDs. This means that they are programmable, as long as you have a flight controller capable of controlling them. It weighs 1.9 grams.
The frame was a fairly easy assembly. Things to note are:
- The main frame must be in a certain orientation. There are indented screw holes on one side, that side is the top side.
- The advertised pictures show the PDB attached to the bottom of the main frame, instead of the top of the bottom plate. Putting it where they planned it would mean that the battery strap could not be used. Mount it on the bottom plate.
- Don’t forget to put in the FPV camera sides before you finish attaching the main frame to the bottom plate.
There were a few extra/spare screws.
Total weight, with everything from the box (minus the XT60) is 126 grams.
Without PDB and legs, 117 grams.
Without PDB, legs and LED strip, 115 grams.
The battery area, on top of the GEP210, is very nice. The battery gets mounted on the same level as the motors, keeping the COG gratify even. There is 106 mm of length and 37 mm of width for the battery. Below you will see a Bonka 3S 1500 mAh battery on top, so a 4S should have no problems either. There are little tabs on both the left and right sides to help keep the battery in place.
Between the bottom plate and the main frame, of the GEP210, you will 15 mm of height to play with for the FC and PDB to be stacked.
The LEDS look really nice in the back, can’t wait to take advantage of the programming through my F3 flight controller.
Below is a picture of the GEP210 with an 1806 motor and a 5 inch, 5045, prop. You can see that these props are as big as you should go and will make the mounting of an action camera on top a challenge. There is about 2 mm that rides on top of the top plate.
Pros and Cons
Overall, I am very excited to build the GEP210. It is fairly light and has a low center of gravity with the battery mounted on the same plane as the motors. The built-in LEDs look excellent and will look better when I program them with the flight controller.
I am a little nervous with the space I between the bottom plate and the main frame and also the space for the FPV camera. Also, the action cam mounting will be a challenge.
Now the fun part of building the GEP210 will start. I’ll make another post on how the entire build goes and what my thoughts are of flying this frame. For the money, the GEP210 seems like a great little frame.
