After the Hubsan H502S, probably the lightest GPS quadcopter including 720P, FPV, GPS & Follow-me, here the Hubsan H502E. The H502E uses the same body of the H502S but here no more FPV ring & Follow-me. Only survive the 720P camera and the GPS module. The objective of this machine with a relatively agressive price is to offer the most easy quadcopter to fly for beginner thanks to the GPS stabilization & RTH. The perfect quadcopter for “Bondes”…
+ 1 x Hubsan H502E (with a 2S 610mAh LiPo with JST connector)
+ 1 x Transmitter (using 4xAAA batteries not included)
+ 1 x USB charging cable
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x Screwdriver
+ 1 x Instruction manual (English)
No visible difference between the H502E & E edition except the red frontal camera protection for the H502E versus a black one for the H502S. This qiadcopter enter into the 230mm quadcopter size. The plastic of the canopy structure is very flexible and should absorbe easily a lot of type of crashes even on hard surfaces.
The camera is well protected from a frontal shock… it’s a good point. The wide lens is perfectly covered by the red element.
A microUSB is here to flash eventually a new F/W
Not a lot of free room when the battery is inserted. Good news, classic JST connector are here… no propretary battery.
The microSD card slot. No microSD card is offered in the bundle. Be aware, no spring/clipsing when you insert the microSD card. It mean in case of crash, the card can be lost.
A little bit more than 152g. In practice no real difference with the H502S including also a 5.8VTX. It means that most elements are shared.
The same model as for the H502S, now they come in red
They are longer. The idea is to extend flight time but the price is will be a less agile machine and more stress for motors. You will have to wait that motors becomes colder between two batteries.
Like the H502S motors are basic 8.5mmx20mm coreless brushed motors
Be aware associated shaft are a little bit more longer than those we can find for such motors.
A flat 2S 610mAh LiPo with a discharge rate announced to be 15C.
The same 720P camear module we can find for the H502S and probably the same as for the H107C+/H107D+.
A wide 120degrees lens is installed. A good point to shoot nice landscapes. In another hand, as you will see with demo flights the frame rate is a little bit low, around 23-25 fps. Second negative point, colors renditions are not faithful… the blue color is too strong. The light sensitivity also is not amazing. Far to be one of the best 720P camera module in the market.
You will have to remove the lower cap of each motor pod to access to two hidden screws.
You will have to disconnect the GPS plugs
The interior part is really similar to the H502S one but here …. no 5.8G linear antenna. Below the large metallic casing, probably the 5.8G VTX have been also removed to gain some weight and increase life longevity.
The transmitter is a basic gamepad style model with only two shoulder buttons. A small black & white LCD display is here. Good news, this small display can print some important telemetry informations such as: Number of satellites received, current heading of the quadcopter, current distance and current height.
The top left shoulder button take either photo or turn on/off recording if long pressed. The right shoulder button engages RTH is long pressed. If you click on the left stick, you enter in Headless mode and if you click on the right one, you enter into Advanced/expert speed mpde. In practice, since there is a GPS assistance, don’t expect the H502E to be fast… it’s a slow machine.
Before each flight or after a crash, I strongly advise to inspect/check that each props spin correctly. WIth such prop’s size, any extra friction can kill fast a motor.
The GPS stabilization works great with very small deviation. An impressive job for a so light machine. But as you can see, the H502E is very slow even in expert mode. What’s a pity you can’t select the flight modes between altitude hold, GPS hold or pure manual flight like with the H502S. It could be a problem in presence of strong Wind….
Thanks to telemetry informations, even if the quad is far, it’s not so hard to bring back the quadcopter to the take off location. You just need to remember the heading of the home point. To shoot a video it’s good to have the altitude value. In windfree conditions, the videos are more or less stabilized but as soon as the Wind start to blow… they become much more shacky… Definitively, electronic stabilzation will be the next feature to include.
Thanks to the GPS stabilization, we can be concentrated to the scene to be shooted or on telemetry informations. In case of panic, just release the stick and the quad will hover in place …. in case of hyper panic… just press the RTH button…. Really, it’s perfect for beginners… Unfortunatlly, it’s working only outdoors. For indoors, since the GPS satellites are not received, you are in altitude hold less accurate and no more RTH of course.
Announced to be sold around 100-110USD, this machine finally is interesting, in the sens it’s probably the most easiest machine to fly with. It’s slow, completly assisted via the GPS… ideal to learn how to fly. and shoot basic 720p videos. I regret that the 1080P module of the H501S was not prefered instead. I strongly advise to stock in advance at least one CW and one CCW spare motors.
