Transmitters and recivers!

[Albear]

Hi all! Im shopping to get a reciver/transmitter and was wondering what you guys think are the best option! Looking to spend under £100.
http://www.robotshop.com/uk/optic-5-...ol-system.html <--- this was the one i was thinking about getting, as it gives me control of 2 motors and another channel for a weapon if and when i want one (i think thats how it works haha) and its a good price. The other one i like is the dx6i series but there a tad more expensive, There are plenty of cheap and chearful but im reluctand to buy something that may turn out to be junk and would rather spend a couple of extra quid on something sturdy and reliable! Thoughts and suggestions please!

Cheers

If you're building a heavy you need a dx6i and lemon rx for full failsafing to pass tech check with a heavy.

If you're building a heavy you need a dx6i and lemon rx for full failsafing to pass tech check with a heavy.

This just because of the built in failsafe capability?

Just FYI, this is not mandatory. Any transmitter/receiver combination that stops a robot with signal loss is fine.

You don't need a particular brand or model of transmitter. However regardless of what model you go with it MUST be able to failsafe on all channels.

I use an old 40 meg futaba set that I fitted a 2.4ghz conversion kit to.

Other setups will work, but the DX6i is the go to standard TX. It has on board mixing and model menus and various other useful features. You can usually pick them up from Ebay for around £60-£70.

Lemon RXs are great. A lot of people are put off because they are so cheap (~£4 as opposed to ~£20 for a proper Spektrum RX), but I've found them to be much more reliable than Orange RX (another common choice) and have used them without issues in all my robots. The Lemon failsafes by taking the throttle to the position it was first bound in, and switching off all other channels. This is the same way most RX failsafe.

OOI, hows the failsafe testing usually done, just by demonstration at the tech check?

[Rapidrory]

With a bot on it's cradle, you usually just push the stick forward until the wheels are moving, then switch off the TX. If the wheels stop turning (in a reasonable time), then you're all good. I should imagine spinners and the like would be checked in the arena.

Thank you Rory, youve been a great help! If you dont mind me asking, what model of lemon do you use and where do you usually get them from? Cheers!

[Rapidrory]

You'll probably want this type: http://www.lemon-rx.com/shop/index.php?route=product/product&path=59&product_id=92
It takes about 2 weeks to arrive from china.

You'll likely want to wrap it in some insulating tape to keep it safe.

What are everyone's views on the Orange T6 Tx/Rx? It seems to have 100% of the functionality of the Spektrum for 60% of the price...

This is pretty decent comparison.

I love my dx6i but I would consider an orange one as a back up.

[Rapidrory]

The Orange Tx is great; it is my main Tx. However once you add £35 shipping from the US on top of the £40 or so it costs (even more if you're caught by customs), the price comes to about the same. The full screen menu and back light are great for when you're trying to change settings when arming up at a show (It's usually very dark).

They can have weird issues though; mine doesn't bind to specific models, so if you select the wrong robot model it will still connect (has caused issues in the past). Alex has one which came with a dead transmitter module. This was swapped out but it doesn't record model names correctly, so you just have to guess which model your bot was bound to... It's very odd to get random firmware bugs like this given they must all be programmed from the same source code, but it seems to be the case.

Thanks again Rory, i ordered a couple! Im sure i can figure out how to set it up.. if not i know who to ask! not sure about the controller though, dont like the sound if the tech niggles you've had with the orange, might just play it safe and get the DX6i

I use the OrangeRX T6 and orangeRX R620 receiver in a few models, and the Turnigy TGY-i6 with Turnigy iA6 receiver in others. Should anything happen with the oranges, I'm swapping everything over to the Turnigy. I like their failsafe recovery and their menu system a lot more than OrangeRX/Spektrum/JR.
