Starting Point

Just recieved my DX6 this is probably a stupid question but the left stick doesnt return to neutral from the vertical direction, is this normal?

[RogueTwoRobots]

Yep that's normal. It's a ratchet system so that on aircraft you can set the engine throttle to a certain speed and let go of the stick. Useful too in robotics for spinning weapons or other weapon controls.

But if you want to use tank steering to control your robot (i.e. push both sticks forward to go forward etc) then the ratchet can be a bit of a pain. There are kits available in model shops I believe to allow you to remove the ratchet and make the stick a spring-return if you wanted to change it.

What some people do is switch the ratchet on the left stick from the vertical axis to the horizontal axis - which does spring return - and use the springs and levers from the horizontal axis to make the vertical axis spring return as the parts are identical. As Jamie said though, having it on ratchet is very useful if you can drive on one stick, it gives you nice easy variable control of spinning weapons

Just to point out that the ONLY receiver you can use for robots is the BR6000 .

*points out ar500* [/quote:1j5w43e7]

An AR500 is DSM2 protocol, and does not work on a DX6 transmitter. Only on DSM2 transmitters like the DX6i or DX5e or DX7 will work with those.

Hi just a bit of an update to let you know where I am with this.

I have bought/ordered the following parts; 4 drill motors and mounts, 4 100mm blue wheels, DX6, TX Charger, BR6000

I am looking to get a wotty100 (decided not to get a sidewinder as it was a little expensice) have emailed Ian Watt and just waiting for a reply from him. Hopefully ill be able to get ont before christmas as this is when i plan to do the majority of the build.

Going to initiall build it out of wood as its cheaper and I can make mistakes on it and then go the HDPE route when the design is finalised.

Battieries I am initailly using the ones that come with the drills and when its working i am going to switch to nimhs.

Can anyone thing of anything ive missed?

[zoll]

also should i have kept the ball bearings from the drill as just realised ive lost aload of them ><

[typhoon_driver]

You don't need them. Just screw a couple of grub screws down the holes that they were in to lock off the gearbox. Or you can go for the cheap option and use a 5mm bolt, screw it down until it just locks the gearbox off and then cut the excess.

I cant seem to get hold of Ian anyone in close contact possible ask him if i can buy a wotty 100 or 180, thanks

[zoll]

I've managed to get in touch with him now, the Wotty100 is 50Amps per channel for 5 mintues, would this be enough for 2 motors per channel?

[joey_picus]

For the types of motors you'll use in feathers, unless you go overboard and use Speed 900s or Astroflights or something similarly powerful it'll be more than enough
