Flysky TH 9x-B with goods and bads

Tx, Rf module, 8ch receiver and the bind plug

Hello dear friends,

Today, I want to tell you about my experience with the TH 9x 8 channel transmitter.

It all started when I finally “compiled” my necessary “list of materials” to build my first proper 450 size heli, with carbon fiber frame, unlike my plastic Esky Belt CPX. On top of many components, it was the well priced TH9X transmitter and to go along I got a 6 and 8 channel receivers also. First impression when I opened the box was of cheap plastic.

The display was not bad, and the sticks and switches had normal feeling, so nothing special here…The good thing about this TX is that you can switch the RF module on the back, and unlike the Turnigy clone sold by HK, you don’t need to cut the antenna wire and re-solder it…When I connected everything to the receiver, I got the bad news: meaning this cheap TX had some serious channel bleeding

like you can see in this movie I made for myrcmart, hoping they will replace my transmitter…which they didn’t do L

This exercise was a lesson learnt for me, and imagine when I did the first tests, I removed the blades (which I strongly advise you also to do.) and I moved elevator right and my motor spooled up to maximum rpm…holy cow….that’s not something I would expect from a new out of the box product…Unfortunately more tests I did, just confirmed it was some factory issue, and changing the gimbal would cost alone about 25 USD…I was so disappointed, and set my build on hold…Even tough I did the movie explaining myrcmart(otherwise a good seller) that it’s busted, they kept saying I just like to complain…

At this point I considered installing the smartieparts upgrade board ~25 usd and the extra backlight lcd from HK~5 usd, hoping that by flashing the firmware to ER9x I could get rid of the problem; but adding 30 usd to the already payed 70 usd would make 100 USD for a product that I couldn’t really trust anymore, and what happens when you fly an more or less expensive heli and you crash it to something or somebory because of faulty TX?

I didn’t want to take the chance, so I decided I go Walkera way, and I bought a Devo 10 bundled with the Master Cp heli and an additional RX-1002 for my 450 project at a good price. The Devo 10 already has backlight LCD, and Usb connection for firmware upgrades, and on the TH9x I needed to buy extra components to have the same features..

As a bottom line: can I recommend the TH-9x?  my answer is no way…I know some of you have good experience with this TX, but I read way too many people having issues with these, and especially considering that no matter how many heli’s or planes you have, you use the same tx, I think that buying something a bit better is the normal thing to do….I am personally happy on my choice, and I fly my Genius cp v2, my master CP and my RCX 450 FBL with the same Devo 10 TX…

I hope TH-9x might have improved since, and hopefully nobody will just throw off the window 70 USD like I did(btw, the TX is still in it’s original box and never touched it since)

I wish you good flying and be safe,
