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)
+ 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)
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.
The ground clearance of the the H26D is important, more than 10cm large enough to carry the 2-axis gimbal
Nice point: since you can carry the gimbal, the battery compartement is now installed on top.
The 1200mAh Lipo occupies all the battery bay.
I strongly advise to tight the screw when the battery is inserted to not loose the door mid-flight.
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
In the middle of each arm, a 1.25mm miniJST connector to connect the propguard including LEDs.
Each of the two landing foot weights individually around 30g
and 6.7g for prop guards
Motors are connector via 1.25mm miniJST connector
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
Other bad news, the pinion is in brass metal while the main gear in nylon. The bass pinion durability will be reduced
Some compatible models can be found here:
Ball bearings (IDxODxW) 3mmx6mmx2mm replacement
Some heatsink are installed on the N50 brushed motors. Not sure it will be very efficient vs time.
Some N50 brushed motors are installed even of on top it’s written N40
Exactly the same model than V666/Tarantula
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
The camera is announced to be a 3mpx model filming in 720p@30fps
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)
The gimbal includes 2 coresless motors
After a very long unscrewing session, you can easily split in two parts the body
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
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.
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
The 2.4G antenna is shielded
and a PA+LNA stage is present to offer the advertised 300-400m of control range.
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
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.
+ Great flyer, sporty as the tarantula/JJRC H16
+ Beautiful design
+ Good control range
+ Headsink for N50 motors
+ Easy motor maintenance
+ Almost Jellofree plateform
+ 120 degrees of FOV
+ Light 2-axis gimbal
+ Potentially a super FPV plateform
+ Around 8-9min of flight time
+ Less than 100USD
– Noisy machine
– N50 brushed motor with a ATBF of 20-30 flights (in average)
– No ball-bearings (MR63)
– No nylon pinion (brass pinion in contact w/ nylon gear)
– Unsual lead connectors
– No microSD card provided
– Gimbal control almost without interest without video feedback
– Light sensitivity of the camera can be better
