am building a robot with my son am using drill motors x2 left and right like tank style and can not seem to find a suitable radio i have been told 2.4ghz.i need a controller so when both sticks pushed forward both motors go forward same with reverse and steering done by the two sticks but am getting confused looking at spektrum 5ex or i see everyone uses 6001 and what is mode 1 and mode 2 please can someone help??????????????
The Spektrum DX5e is fine. It comes with an AR500 receiver which is suitable for robot use and is very simple to set up.
6001 - I think you are refferring to the BR6000 receiver which will work with the DX5e. As you can buy the DX5e/AR500 combo for about £60 I dont really think you need to go there.
The DX5e has two sticks for a mode 2 set up, the stick on the right has a spring to centre the stick on the left/right and up/down. The stick on the left has a spring to centre it on left/right. The up/down motion of this stick does not have a spring return. This is the throttle on things like aeroplanes etc.
Mode 1 has the stick in reverse. Mode 2 is generally a right handed set. Mode 1 is a left handed set.
Bearing in mind you do not have a spring return on the up/down of one stick, we set the mixing up on all our so we drive using a single stick (the right hand one on a mode 2. left hand on a mode 1. Most people use a mode 2 as far as I am aware.)
This is easy to set up and is just a switch which says mix on the front of the transmitter, just turn it on. This avoids having to open the transmitter up and change the springs around or driving without the spring return.
Hope that helps, tried to keep it simple.
Just a point though, you can get a DX6i for about £100, can sell the receiver that comes with it on ebay for about fourty and buy an AR500 for about £35. This will allow you in future to run more than one model from a single transmitter and it gives you a lot more adjustment and options for fine tuning.

Oh and by the way, unless you have a seperate receiver battery, put one of these in.
http://www.technobots.co.uk/acatalog/RC_BEC_Regulators.htmlhttp://www.technobots.co.uk/acatalog...egulators.html
most battery eliminator circuits on speed controllers are not adequate to power the receiver.
MODES ...http://www.rc-airplane-world.com/rc-transmitter-modes.htmlhttp://www.rc-airplane-world.com/rc-...ter-modes.html
MODEs 3 and 4 are rare.
Two stick steering is OK ...
But the driving norm for a bot is ONE stick ( two axis )...usually the right stick on a MODE 2 Transmitter....or left stick if you wanted to use MODE 1.
If you use a single stick then the transmitter outputs are mixed either in the transmitter or at the speed controller/s or sometimes via plug in piece of kit called a V tail mixer.
The ELEVATOR axis on the transmitter then controls forwards and reverse of both motors and the AILERON axis controls steering.
All very confusing for a Newbie...
Just for a newbie? I dont know why Im commenting on this because Im now banned from our electronics after releasing the magic blue smoke from just about everything Ive touched recently:rofl:.
Which speed controller are you using by the way? That would tend to decide the mixing you use.
Andy
So Paul,
Recommendations:-
A cheap DX5e and AR500 receiver combo ...VERY BASIC.
DX6i or a DX7 and BR6000 receiver with lots of bells and whistles.
A DUAL controller such as the Scorpion XXL Speed Controller and the Sabertooth Dual 25A Motor Controller Universal.
http://www.robotmarketplace.com/products/speed_controllers_main.htmlhttp://www.robotmarketplace.com/prod...lers_main.html for descriptions of the above...
OR two seperate controllers such as the Electronize.
http://www.electronize.co.uk/electronic_controllers.htmhttp://www.electronize.co.uk/electronic_controllers.htm
And a BEC or receiver battery.... http://www.robotmarketplace.com/products/battery_eliminators_and_regulators.html%20http://www.robotmarketplace.com/prod...egulators.html for examples of BECs ( Battery Eleminator Circuits )

if your after a cheap radio i just bought 5 of these for some roboteers out our way and all 5 have been through an event. without fault.
they failsafe on every channel (output nothing when the radio is off so the standard speed controller failsafes work) and the range is great.
cheaper then the dx5 too :) and hackable to 6 channel im sure as there is a 6 channel version of it for sale.
no other features other then servo reverses but i never used the other features personally!

Just be aware that some of these very cheap 2.4 radios are not legal for use in the UK. Please check before you buy.

The T4A makes a good backup transmitter or a take anywhere unit. Drop it, scratch it, leave it in the car and forget about it. This is what the T4A is all about.
Multi Flapperon, mixer, vtail, FPV, robot controlling hobbiests do not order!
just thinking if you are why they say robot controlling hobbiests do not order!
Just a point about Woodys comments. People have experienced some difficulties with the DX6i/BR6000 set up because it can lose its bind on occassions (disconnects from the tx). The DX6i does work very well with the AR500. As I understand, the BR6000 works well with the DX7.
By the way you can get the BECs and spped controller from http://www.technobots.co.ukwww.technobots.co.uk and the Spektrum from any good model shop.

thanks everyone for your help am running 2 bosch drill motors 14.4volt, drill number gsr14,4ve-2 at 12 volt sealed lead acid battery at 2.3ah speed controllers i have brought from matt two electronize fr15 to power each motor and running 100mm wheels and am seriously thinking about the dx5 transmitter and reciever and seperate reciever batterys as the fr15 has bec adding another battery will it not kill the reciever? am unsure also what class to enter with bits i have any help and advice is greatly welcomed
Paul, Just to let you know that I would definately recommend the DX5e sets, we have 10 of these at school and they work just fine.
Also with the bits you have you would be looking to build a featherweight.
The best advice I can give though is get yourself along to an event and ask someone to show you how a featherweight is put together.
Hope this helps
Will
The Electronize BEC will probably be just fine ... some other makes of speed controller have an issue supplying enough current for the Spektrum Receiver.
So ...DX5e and AR500 plus 2 Electronize controllers ...seems fine ...bind the receiver to the transmitter.. plug the controllers into Ele and Aile on the receiver ...select MIX on the DX5e transmitter and with a bit of luck things will work.
A quick post on here should easily sort out any motor rotation / direction probs.
Just a question, sorry to hijack the thread.
I was wondering if anyone could help me. I have a DX6 mode 1, and am using two single channel ESCs. When I use the basic single stick mix, it puts turning on aileron (right-left on right stick) and Fwd and Bwd on the elevator( up-down left stick) how could I mix it all to one (preferably left) stick?
Mode 1
Left stick = Elevator and Rudder
So you need to pick a Ele and Rud mix = Vtail
Flaperon, V-tail, and Delta Mixing are available for aircraft that require these functions. The flaperon feature is used when two servos are located in the wing, one to control each aileron plus this function allows the ailerons to be drooped or raised while still functioning fully as ailerons. V-Tail Mixing combines rudder and elevator for V-Tail operations.
http://www.spektrumrc.com/Content/PDF/dx6manual-english.pdfhttp://www.spektrumrc.com/Content/PD...al-english.pdf Page 33.
TO ACTIVATE V-TAIL (VTL) MIXING
1. In System Setup mode, press the SCROLL button until €œMIX WNG€ appears on the screen.
2. Press the CHANNEL button once to access the V-Tail Mixing screen.
3. Next press either the INCREASE or DECREASE buttons once to activate V-Tail Mixing

- its because it doesnt have an onboard mixer, 99% of speed controllers have that built in anyway so its a moot point :) they work good.
