Rebuild double trouble help

So I dusted off double trouble my fw clusterbot which has hung on the garage wall for years and decided to rebuild it for the kids. I don't want to spend loads on it as its for the kids lol, got sum questions if anyone can help.

I need 2 cheap transmitters and recievers with failsafe, anyone recommend my cheapest option. I only have 2 br receivers now and they are in raging reality and k9.

Also do u think I can run 2 12v cordless drills with 100mm wheels on 2 x 7.2 Nimh packs on a sabertooth dual 12a for each robot or will I need a 25a dual.

What's the current rule on clusters when one half is immbolised.

that's what i'm running in scruffy and its running nicely (2x12v drills, sabertooth 12a and 100mm wheels)lol

What voltage/amp packs u running mate

I wouldn't bother with a sabretooth. Too easy to fry them. Look at the brushless converted controllers that the auzies have made. Dave has em in his 360 thread

im using a 2x7.2v in series (14.4v) and the packs are 3800mah but that pack is going in my 4x4bot and a 3000mah is going in my 2wd

Ok cheers, will look at that Gary, had a new faulty sabertooth once but haven't been a bad controller in my old fw's, one in k9 seems to work well, but these clusterbots being 6.6kg each tend to bounce off robochallenges arena roof when flipped so need something that can take that!

Cheap... er than a 5E. :lol:

You can get those RadioLink Tx/Rx combos for £25, but you pay or what you get....

You can get DSM2 Rxs on eBay for around £6, just search for Orange Rx.

Sabertooth controllers have current limiting built in, so any spikes and they cut the power, in a 13.6kg bot the 12a model can give some juddery output when you're being aggressive, but since your robot is in 2 halves it should be fine.

i found those rx on ebay so will buy 2 of those, are their any tx a little better looking about lol,

i see i can get dx5e for about £45 each. But wondered if anything inbetween, whats the giant cod tx's, i have heard people talking about.

That's the Radiolink one.

Questionable reliability...... But can't argue with the price, plus they have built in mixing. Can't use OrangeRxs with them though.

do u think this will do the job, how do you bind the orange rx

http://www.kingslynnmodelshop.co.uk/Rad ... _info.html

Didn't know the DX4E existed!

You bind by plugging the 'Bind Plug' into the Rx on the Bind/Bat channel and powering it up.

You then hold the training switch on the Tx and turn the power on, you'll hear some beeps, frantic flashing will become constant on and you're done.

Release the training switch and remove the bind plug.

You can bind 1 Tx to as many Rxs as you want, but an Rx can only bind to one Tx.

It's a fake btw, not related to Horizon Hobby/Spektrum

edit: Actually scratch that, appears only some of them are fakes, there is a legitimate model http://www.spektrumrc.com/Products/Defa ... =SPMR44001

Aha, here you go 'Attention: Horizon Hobby has confirmed that all Spektrum Products being sold by KoKo Technology are counterfeit. We consider it a danger to use these products, waive all liability and will not support any warranty or service in regards to them.'

do you think the link i have posted could be a fake/copy tx?

No idea, just know there's a few going around

Unlikely. King's Lynn model shop is listed as an authorised seller for Horizon Hobby UK.

Horizon Hobby are the resellers for Spektrum so just look for that.

Yeah, they're probably fine if so, I'd originally thought on hearing about fakes that all of the cheap/plastic style were pretend Horizon gear, turns out it's only a sub-set of the cheap plastic ones!

Ok, gonna go for 2 of these, good enough for the kids

Apparantly the orange rx will work with dsm2 are all spektrums dsm2?

I believe so, should be easy to check. New ones are DSMX, I'm not sure about backward compatibility.
