Haynes Manual Build a Robot

TBH, anything from the OrangeRx range is good (I use a Tx6i + R618XL) but you do need to check that the receiver you are using transmits on the protocol that the transmitter uses (So DSMX to DSMX, DSM2 to DSM2 for example). This isn't normally a issue as both the one I use and the one DoubleTrouble noted above support both.

Certain models of receiver, like the FlySky series I think, have proprietary protocols which means you can only use their model of receiver with their transmitter. Same for the Devo 7E but those can be flashed with a firmware update to support the DSM protocols I believe.

That receiver should work with my Dx6i by the looks of it, just need to decide what ESC to get now as getting mixed reviews on here and online about the sabertooth or others

[Ocracoke]

I don't own a Dx6i so I don't know if this will work for you but on my OrangeRX T6xi, I am able to do mixing on the transmitter (where two channels are controlled by one stick). Using this, I am able to use a pair of TZ85As to drive The Honey Badger 2 (my featherweight) and will be doing so for its successor.

If you can't use transmitter mixing, then a secondary mixer also works well and has the same effect as described above but these can burn/break on you, leading to a loss of control.

[AdamST180]

I think i might just get the matching spektrum receiver that goes with the Dx6i as looks like can get one from ebay as at least that should all match and work then

[Ocracoke]

Makes sense, I can't see them being that expensive

Going back to the ESC stuff, a FeatherTwo Dual is likely to be more reliable than a Sabretooth and possibly better value for money - I know Madusa uses one but with any dual ESC it would seem, there is a tradeoff in terms of how much amperage they can deliver to a motor. I would prefer going with a setup described above as it can handle more load but it is more complex to get set just so (I spent an hour tuning the trims on my transmitter to get it moving in a straight line).

Beyond that, things like wiring in a LED and removable link is relatively straightforwards.

[AdamST180]

Yeah the book tells me how to do the link so hopefully thats easily enough, and LED's are simple to, the FeatherTwo are out of stock at the moment but will keep an eye on them, as im only running drill motors hopefully will be reliable

I have spoken to Rory a feathertwo duel can run 2 12v 550 (standard drill motors) overvolted per channel so they are plenty. Also they should be back in stock very soon

Perfect will keep an eye out for when they back in stock and go for one of those, is that Rory from Nuts?

[Ocracoke]

Certainly is.

[AdamST180]

Good stuff

[AdamST180]

I'm tempted to buy one of these so can practice driving etc and with the transmitter etc as they sound like a lot of fun

Antweights are a bit fiddly to build (well, I find them anyway, I have all the delicacy of a concrete breeze block) but they are properly good fun. Feathers are a bit of a different beast in how the drive purely because of the size/power difference but the principal is the same

[James Williams]

Thanks for all the feedback Theo & Michael. Since I already have the FeatherTwo I may as well try that with the old receiver & if that doesn't work I'll know what's wrong & what to do about it.

Adam I have one (or two) of those Shakey antweights & I cannot recommend them enough. Not only are they fun but they also can teach you a lot without you even realising it. For instance since they run on Lipo batteries I learned how to handle them properly.

[AdamST180]

Yeah I think I will invest in one, I assume I need to get a charger for LiPo's?

[Ocracoke]

Yep, you need a specialist charger for LiPos. A Turnigy Accucell 6 is the charger I use, never let me down yet. You'll also want to invest in a LiPo bag to charge them in, which are dirt cheap anyway.
