TEST: JJRC H26D, the big brushed sporty machine with builtin 3mpx wide angle camera

null

INTRODUCTION

After the excellent YiZhan X6 “tarantula” rebranded by JJRC as the H16, here is a new large brushed model now including a mini-gimbal + camera module: the JJRC H26D. Don’t dream too much, no stabilization here with the gimbal but “just” the way to control pan/tilt via the radio. The H26D have a 3mpx camera with lens having a 120 degrees of Field of view (FOV)

BOX CONTENT

+ 1 x JJRC H26D CX-10C (with a 2S 1200mAh LiPo with mini-tamiya connector)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x USB charging cable
+ 4 x Prop guards
+ 2 x Landing gear
+ 2 x Spare props (1 CW, 1 CCW)
+ 1 x Screwdriver
+ 1 x Instruction manual (English)

OVERVIEW

The general design of the H26 is really nice mimic last AP models. The size of this machine is even more bigger than the tarantula. The pastic quality is good, enough to absorb most cases of crash. The two landing legs are huge.

-Front view

The ground clearance of the the H26D is important, more than 10cm large enough to carry the 2-axis gimbal

null

-Side view

null

-Rear view

null

-Upper view

null

Nice point: since you can carry the gimbal, the battery compartement is now installed on top.

null

The 1200mAh Lipo occupies all the battery bay.

null

I strongly advise to tight the screw when the battery is inserted to not loose the door mid-flight.

-Bottom view

null

null

A tiny power switch can be found and three different port. Two to control the roll & tilt of the gimbal, the last one (in red) to power the camera module

null

In the middle of each arm, a 1.25mm miniJST connector to connect the propguard including LEDs.

null

-Weight

Each of the two landing foot weights individually around 30g

null

and 6.7g for prop guards

null

null

Motors

Motors are connector via 1.25mm miniJST connector

null

null

Good news, you can remove/swap a motor without disassembing everything by 1) removing the props, 2) removing the shaft then 3) the two screws holding the motors are accessible. More no soldering job to do.

Bad news too, no ball-bearing, but some bronze bushings (3mmx6mmx2mm) MR63

null

Other bad news, the pinion is in brass metal while the main gear in nylon. The bass pinion durability will be reduced

Some heatsink are installed on the N50 brushed motors. Not sure it will be very efficient vs time.

null

Some N50 brushed motors are installed even of on top it’s written N40

null

Exactly the same model than V666/Tarantula

null

null

LiPo

A 2S 1200mAh LiPo battery with a mini-tamiya connector… strange choice not often used (probably to sell more spare batteries). No discharge rate mentioned

null

null

null

null

Camera module

The camera is announced to be a 3mpx model filming in 720p@30fps

null

The lens have a field of view of 120degres, a good choice IMHO, not too large (to be affected with fish-eye effect) and not too narrow (as usual)

null

The gimbal includes 2 coresless motors

null

Disassembling

After a very long unscrewing session, you can easily split in two parts the body

null

null

Classic chips are here, a MPU6050C for a 6-axis stabilizaton and a XN297 as RFchip. Unfortunatly, I was not able to bind the H26 with all protocol XN297 based implemented in deviationTX

null

The 2.4G antenna is almost installed vertically inside the canopy, a good news if you are looking for long distance control in the horizontal plan.

null

Transmitter

A classic JJRC chassis but now including a small LCD display. It’s always a good point. Both shoulder bumpers have in practice two functions if pressed backward or upward. The left one is associated with photo (back) or camera triggering(front). The right shoulder button when pressed back select one of the three speed mode. For the two first, “demo1” is written on the LCD, while “demo2” only for the expert. All rates (ruddler, aileron, elevator) are propotional to the selected modes. The novolty is the gimbal control via the four left stick trim buttons.
Finally, two “pot” buttons, in practice to be clicked on them to select a kind of altitulde hold for the left and the headless/ one key return for the right one (if long pressed). To calibrate gyros, you need: 1) to be in expert mode (demo2) and 2) to push both stick in lower-left position

null

null

The 2.4G antenna is shielded

null

and a PA+LNA stage is present to offer the advertised 300-400m of control range.

null

FIRST USAGE

As you can see and hear, the H26 is very Noisy …. like the V262/V333/V666 and tarantula…. No miracle since the same N50 motors are here. The nice surprize is the remaining sporty attitudes of the machine despite the extra weight associated with the mini-gimbal cam combo. A good point. The H26 is really easy to fly with but need a wide open space. In expert mode, it’s a rocket (comparatively for a brushed model but last faster than a JJRC X1). The stability is here …. a very good to shoot videos. Another good news, is the stability in videos, almost jellofree, results far superior of the original tarantula’s videos. With some little modding, I am sure it can be completly jellofree. The camera quality is correct while not being amazing. I regret a little bit the average light sensitivity. In practice, the camera control possibility without any real-time feedback is very limited to some proximity flights. I regret that the radio don’t offer at least a sound or visual indication of the central gimbal position. In this case, we would need just to count how many click to apply to have a given angle. An interesting mod, would consist to remove the builtin camera to install a better mode or (and if the H26D is not first derived with a pure 5.8G solution) to install an FPV camera.

Another video with higher altitudes

CONCLUSIONS

With the avalanche of JJRC models, it’s a little bit a lotery, but I have to say that the JJRC X1 and this H26D are two good models. Of course, it’s never perfect but promising. The general design of H26D is really nice and despite it’s a little overweight it remains a sporty while offering (almost) jellofree videos. For less than 100USD, the H26 represents a serious competitor to the syma X8C (not yet for the X8G) and the MJX X101. If you are looking for a cheap video plateform to practice before to buy a real brushless plateform, the H26D is really interesting. I deeply hope/dream than JJRC will propose the pure 5.8G FPV version with the same 120deg lens …. Let’s hope… As for all models equiped with N50 motors, I strongly advise to stock at least one CW and one CCW motor.

    i was wondering if u would know why mine will not fly is there a way i can send u a video of how it is

  • Moreyru says:

    I received mine a one motor is stuck. Does the motor are the same of the tarantula x6 and the jjrc h16?
    Thank you!

  • Moreyru says:

    Hi,
    I downloaded WifiUfo to use with my H26w but the video on my phone and the recordered video appears upsidedown. Any suggestions on that?

    Thanks

  • Epilef says:

    I have a question. I’m anxiously waiting for my h26d to arrive and want to be proactive. Order extra motors, just incase it needs replacing.
    Upon reading this thread, I want to know if there are brushless motors I can swap for these brushed ones?
    Thanks in advance

    • SeByDocKy says:

      No you can’t replace a brushed directly with a brushless model. For brushless motor, you need some complex ESC instead of basic transistor for brushed.
      So you need to replace ESC but since actual transistor are integrated into the JJRC H26 board, you will need also to replace the FC & the receiver. The total bill will be the price of the quad itself.

  • Yyz drone flyer says:

    I bought this drone from Banggood. After 21 days waiting. Flew it for a day maybe around times, which is the number of batteries I have.
    Now it does not even fly. The quad will try to take off, all props going. Then it’ll just die.
    Question: is it the battery or the motors that needs to be looked at. Also the other batteries I have is not like the stock one, where you can only install it the one way. But with the other batteries you can inadvertently install the wrong way.
    Power is off but if it shorts, the props will spin. Did I short the board well?
    Thanks for your response.

    • SeByDocKy says:

      I am afraid … some friction was present in the shaft sections (no enough grease ?) and the FET now are damaged 🙁 … I guess the guilty is the FC but I am not completly sure …. Inspect first the shaft section and grease it.

  • Jim Warn says:

    Where can I get instructions for replacing the receiver board on the jjrc h26d?

    • SeByDocKy says:

      You can’t add/swap the receiver. Everything is integraded into the same board. Sorry …. (like for 99.99% toys)

  • kev evans says:

    Hi could you please have a look at my video and let me know what you think it has never flown and I have swapped out both batteries with the same result I think it is a faulty receiver
    thanks kev

    https://youtu.be/DEwmCuwB5lo

    • SeByDocKy says:

      Are you sure the battery is correctly charged ?

      • kev evans says:

        yes i have tried 2 batteries 1 of which i know is good and i also charged the battery with 1 of my good chargers and the same with the transmitter i have swapped out the batteries with the same result

        • SeByDocKy says:

          ok …so you have to open your quad and probably the radio too … check is antennas are connrectly installed/solcered … motors can spin more or less freely with hands ?

  • kev evans says:

    The motors all feel the same ,all feel good
    I will strip it down and let you know if I find something ,
    Thanks Kev
