More about radios

FlySky FS-i6I’ve been finding all kinds of cool things since my last post. So much in fact that I need to write some more about radios. I especially want to talk about the FlySky FS-i6 and the Turnigy 9X. The FS-i6 is a 6 channel radio and the 9x is an 8 channel unit (in spite of the ‘9’ in the name). Both are 2.4 GHz radios with frequency hopping spread spectrum (FHSS) technology and both get mixed reviews but mostly good. What stands out to me is the price – the FS-i6 is only $49.95 ( and the Turnigy is $69.64 ( I have the Turnigy in hand and the FlySky on the way (I spent an extra $3.00 and ordered from so I wouldn’t have to wait a month for shipping from China). If you like to tinker, this really is the Golden Age of RC flying…

Turnigy X9

My first cheap radio is the Turnigy X9. I bought this radio for 2 reasons. The first was price. Less than $65 for an 8 channel radio that manages to get good reviews? I have to try this. Yes I know it’s probably no Futaba… Price was only one reason though. I also liked the idea of being able to modify it. No way I’m going to hack up my Taranis, but a $65 radio? Why not? The only major issue I found in reviews is the holder for the transmitter batteries. Supposedly the can lose contact with the batteries, which makes the Tx shut off while you’re flying. I’m replacing the stock AA battery holder with a nice 9.9V, 1500 mAh LiFe battery I got from HobbyKing. I might also replace the LCD with a back lit one.

The X9 comes with a Turnigy iA8 8 channel Rx that supports sbus. That will make it nice for hooking it up to a mini Pixhawk on my CrashTestHobby 4 channel Pelican that I want to build into a many fixed wing drone. I’m really looking forward to testing this radio.

FlySky FS-i6

My second cheap radio is the FlySky FS-i6 6 channel radio. Ordered this based on a tip from CrashTestHobby. I don’t have this radio in hand yet, but I’m looking forward to testing it. It will go in my 3 channel Pelican. For $52.99 it was hard impossible to resist. One strange thing about the FS-i6 is that it runs on only 4 AA batteries. Most Tx’s that use AA’s use 8. Don’t know what that will do for Tx time, and a LiFe or LiPo pack won’t fit the battery compartment. Guess I’ll wait and see…
