Quanum i8 8ch Radio Control Transmitter 2.4GHZ

The Quanum i8 TX is specifically designed for the multirotor users. In this review we are going to explore the features of this radio transmitter.

Get the Quanum i8 TX from Hobbyking.

The Quanum i8 transmitter has a 8 channels. It’s been matching designed to the APM and Pixhawk flight controller, to bring ease of use and programming to those complex sysyems.

But you can also use it on many other flight controllers as it supports the popular PPM and PWM receiver type.

If you are looking for a basic, cheap, easy to use, 8 channel TX, i think this could be a good option.

Includes

  • 8 Channel Radio Receiver that supports PPM and PWM outputs (iA8)
  • Rechargeable LiPo Battery 1S 3.7V 1700mAh
  • Micro USB Cable (for charging and firmware update)
  • Bind Plug
  • Stickers of mode labels (white and black)

Features

Nice clean design.

It has no screen. Good thing is you don’t need to worry about settings, or getting intimidated (espcially for beginners). But the down side is you have to connect your TX to a computer in order to change settings and configurations.

Full 8 channels, 4 for the gimbals, and 4 for other controls, including a 6 position pot on top right (matches the number of flight modes on APM and PX4). Note that the 6 LEDs on the top of the TX are indicators of this pot.

There is a 3 position switch on the top left and 2 sliders on both sides as well that are easily accessible.

PPM/PWM outputs

One of the greatest feature of the RX is the capability of outputing both PPM and PWM at the same time.

It’s great if you prefer running PPM on your flight controller, but want to put in some components that requires PWM inputs, such as servos, or camera gimbals. With this RX you won’t need to run by your FC as a pass through.

USB Connection

Firmware can be updated through the USB port. Also you can charge the battery using USB too.

I was curious that if this TX can be connected to my computer and used in simulators. The answer is no, it doesn’t work.

Compatibility with APM/PX4 and other FC

It just works with these FC straight out of the box, no changes required. But if you are using it with other firmware or FC, you will still be able to change the setting via software if required. (such as reversing channels, re-map channels and so on.)

Channel remapping and reversing can also be done simply using the sticks, refer to the manual for more detail.

Gimbals and Quality

It’s not a high end TX, so don’t expect it to be perfect. It’s made of cheap plastic, and the gimbals are not the best. But it’s a decent TX with quite a few impressive features for what it’s worth.

Failsafe

It has failsafe built-in.

Sticker Labels

The provided flight mode labels are for you to put under the LED indicators. They are great reminders for someone who just started using this TX.

Range

I have yet to test range yet but will do that once i have some data. But that could take some time as it’s too cold to fly at the moment.

Hi there,
Did you actually made this receiver work? I just bought Turnigy 9x with the same receiver and … it seems to be acting quite weird. And it makes me think if it is working in PPM i-bus mode at all.
When connected via B/PPM port (signal+power+gnd in the same row) it wants to bind every power cycle. It binds to transmitter but it doesn’t talk to Omnibus F4 (BF, connected via RX1).
Transmitter cooperates very well with Turnigy iA6B.
I didn’t try PPM mode so far. I’m just looking for confirmation if it does do i-bus/s-bus.
Thank you

Is there a way to adjust the endpoints on the channels? I cant get the failsafe, atti,GPS to hit the stops correctly.

I’m having the same problem with Naza M V2. Any luck finding a solution?

Does the battery need charged once out of the box?

Where is this software for remapping channels? Do you have a link, please?

Hi. I am trying to use channel 7 or 8 to control the pitch on my gimbal but can not see how to assign them though mission planner, any ideals ? Darren

Hi oscar! Great review!
I was wondering how to enable the failsafe, because when I turn off the controller but the quadcopter still has the battery plugged it goes crazy and the motors go to full throttle.
Thank you!

You probably have the answer, but point 1 on the rotary switch is the default failsafe. Set this to RTL in Mission Planner.

Hi Oscar,

Just wondering if this controller ca nbe used on a Syma X5C which I am using to learn to fly UAVs

Thanks,

Does this support mulitple models? Is that what those 6 LEDs at the top indicate?

Reply
hexo 18th January 2016 - 3:46 pm

Oops, just noticed in your review that the LEDs match pot position.

Reply
Oscar 20th January 2016 - 11:13 am

no unfortunately it doesnt… the 6 LED basically indicates the position of the knob on the top right…

Thanks Oscar for the input.

I think that I will move in the direction of building a quad so that I can learn about the inner workings of these pieces of equipment.

Any suggestions on web stores for buying components to build a 3DR, Walkera, Yuneec or DJI style quad?

Thanks again,
Jeff

I think generally Hobbyking is pretty reliable only problem they have is expensive shipping… if you want cheap try banggood?
