Title: Set up for Rc ship advice
Post by: MvModeller on November 07, 2018, 11:26:13 pm
Hi
I'm looking into buying a Radio set for a Ship I'm building..
I've seen a nice set... the Turnigy 9x. Now I've I know this many channels is pointless maybe for an RC Ship, however I'm also building a Tamiya Scania Rc truck that requires extra channels that I'd like to use this set up with also.
I've read that this radio set up is mainly for Planes and alike, Is it frowned upon to be using this signal type for land based models? Or can we get away with it as it's 2.4ghz?


Cheers

You can use pretty much any 2.4 set on anything :-))


I'd advise against the 9x though, I've read all sorts of dramas about them - chief of which is that it doesn't store bindings, which in my eyes makes it totally useless. If I were looking at spending under £100 on a radio set, I'd be looking at the Taranis QX7

I bought the 9X only to discover the hard way that while it has a multiple model memory, there is a "feature" ( >>:-( ) of the system that prevents it binding to more than one receiver.  So you can only use it for multiple models if you re-bind the receiver every time you swap model. I would go with Andyn's recommendation, or this one (https://hobbyking.com/en_us/turnigy-tgy-i6-afhds-transmitter-and-6ch-receiver-mode-2.html), which I can assure you works fine!

The i6 is good, but quite poorly made and the other day while running with someone who had one his seemed to be swamped by my Taranis. You do get what you pay for though...

I too have been contemplating the Turnigy 9x which appears to satisfy my requirements. (My Clyde Puffer uses 6 channels and I need a conveniently sited pot for moving the boom sideways and a 3 position switch avoids using the right hand stick for operating the hoist.)
It looked as if the Taranis would need setting up via firmware to get PWM on all channels.

The Taranis is PWM on 1-8, sbus on 8-16, like most high channel radios.


Programming a Taranis couldn't be easier with opentx companion, flashing rx's is a bit of a pain as you need to put jumper pins in the tx's module slot, but easy enough done

Thanks Andy, that's really helpful - hopefully useful for MvModeller too!

Cheers for all your suggestions and Advice, after looking into them I have decided to go with Gregs recommendation. The Turnigy i6.
The receiver that comes with the set up, looks pretty open, not water proof? Can this be changed? Or would it jist need some mods to waterproof?

I've never seen a waterproof reciever, by nature they need holes in them to plug the servos in

Ah okay, I remember seeing a Waterproof speed controller so assumed a waterproof reciever would be on the market also.


Thanks Andyn

I've "waterproofed" receivers and servos in the past with melted wax from a lit candle.
Just drip it over the circuit ..... twice!
Easily removed with a heat-gun / hairdrier or-the-like.

Take the Rx case off first!   ok2

To waterproof a receiver put it in a small balloon, put vaseline on the wires coming through the neck of the balloon then a tie wrap round the neck to seal.
