Team Durango DEX408 - Which components
 

Morning

I've pre-ordered a DEX408 from JeSpares, a little Christmas present to myself..

Anyway I'm thinking about which components to stick in to the car, at the moment I'm thinking about using the following:

Motor / ESC - Tekin Rx8 Esc & T8 2050kv Motor
Radio Gear - Spektrum DX3S V2 3CH DSM
Batteries - 2 x Turnigy nano_tech 5000mah 2S 45-90C Lipo
Servo - Spektrum Digital High Torque Metal Geared Servo
Tyres - Don't know yet idea's welcome..

So I'm wondering if the components above are the right ones for the job? Or if theres anything I've forgotten?

I do a bit of racing with colleagues on a private work track at 1:10th scale so I'm totally new to 1:8th. I'm hoping that the class will pick up in the UK as theres lots of car's around now.

:thumbsup:

A lot of people are saying that the 1900kv motor is plenty powerful enough, the 2050 is delta wound and thus well suited to large high speed tracks whilst the 1900 is star wound and will have a bit more bottom end grunt.
You could also wait and see what price the new LRP iX8 esc is, just another option. Not heard of anyone who's got one yet though.

You could also look at the Gens Ace batteries from giantcod.co.uk 5000mAh 50C cells at £35.44 each. This is then from a UK distributor and many people are saying their better than the Nano-techs. GiantCod have a forum with some independent testing done on different cells, well worth a look.

Not sure about the Spektrum servo, most people use Savox. Have a look at a 1256 or even a 1232, they might be cheaper and/or better spec than the Spektrum. Look for 20kg torque for steering.

Tyres will depend on what surface your running on.

as for kit here are my suggestions..


Motor / ESC - Tekin Rx8 Esc & T8 2050kv Motor
Radio Gear - futaba 4PL
Batteries - 2 x Turnigy nano_tech 5000mah 2S 45-90C Lipo
Servo - Orion Vortex High Torque Metal Geared Servo
Tyres - Dboots A compound

Spektrum radio systems can be tempermental at times and feel cheap and flimsy, 4PL is in another league IMO

Cant help yourself can you?? You are a total bell end
Another dig at durango after you said you were staying off durango threads.

I know it's a truggy,but I've put a XErun system in my 6T. For £130 you can't go wrong. I'm using Nano tech 6000 4s which I know won't fit yours but hobby king have a just released a 2s 6600 Nano tech, if there anything like my 6000 they'll be good.

One thing to look out for when choosing an esc for 1/8th electric is that most only have a 3A BEC which can struggle to power a half decent servo. The Tekin RX8 has a 5A and the LRP iX8 has a 6A BEC that showed be more than enough.
If you do get an esc with with only a 3A BEC there are ways around the issue like using a separate BEC, or using a high voltage servo and then wiring the power side of the servo up directly to one of the Lipo's but this could give a small issue of one pack being discharged slightly more so could take longer to balance. Both of these will also result in a less tidy install off course.

Were did you come up with that idea? Spektrum radios are among the best.They dont feel 'cheap or flimsy'

I have had both the Dx3r pro and the 4pl. Both felt the same. I did prefer the screen on the 4pl though,but liked the drop down wheel on the dx3r pro.

er there the same thing :p

why? because I owned a dx3s and had nothing but problems with it.

Thanks for the great feedback there guys..

I've revised my list as follows:

Tekin Rx8 Esc & 1900kv Motor
2 x Gens Ace 5000mah 50C 2S Hard Case Lipo pack
SC1256 Savox SC-1256 Coreless Digital Servo

I'll use my current radio gear and try and get a go with someone elses before I decide which way to upgrade.

I'm looking for a UK shell painter now as my previous attempts have led me to understand I'm not up to much when it comes to painting.

:thumbsup:

any are good but i use mike parker

Sounds seriously good.
Love the Durango car. Its my 2nd favourite :)
Keep us updated on the build etc.

For painting i would use Outlaw graphics ( prices are unbeatable)

Or Ian. Seen some amazing work from him.

But anyone who paints your shell on his forum will be good. :thumbsup:

Thanks.

jon miller at rcs graphicworx for paint

Ian (eyeayen) has just finished my Serpent 811be shell, and you can see pictures of it in pages 4 and 5 of his thread here http://www.oople.com/forums/showthread.php?t=81411

His work is simply outstanding.

Bits Ordered
 

Morning.

I've ordered my bits now - I'm quite excited.

I went for the import route on the batteries in the end, as I have some time to wait for the kit anyway. Heres the bits I'm waiting for.

Tekin Rx8 Bl Esc - 4030 Bl Motor 2.5d 2050kv 1/8 Sys
2 x Turnigy nano-tech 6600mah 2S2P 65~130C Hardcase
Savox SC-1256 Coreless Digital Servo
Spektrum DX3S V2 3CH DSM
Pro-Line M3 - Crime Fighter 1:8th Off-Road Buggy Tyres


I'm talking to Ian about the paint job too :thumbsup:

Thanks for your advice, much appreciated.

Hi,
Choice of equipment would seem to be pretty good.
I run the Tekin Set-up you are propsing in my car at the minute and it's bomb proof. I have it on a 21 pinion. Which is a little on the undergeared side, but it's good for short track indoor racing.

Radio should be fine, make sure the servo has 15+kg of torque and somewhere around 0.1s 0-60 degrees time and you'll be good to go.

Cells. I run 4600 saddles in mine. It actual makes the wiring neater than running sticks.. I'll post a nice install pic on here when I remember!

Tyres: Depends on surface. For bashing about dBoots Mulitbyte will give you a good level of grip on all sorts of surfaces... Another good all round tyre will be an angle spike or such like...

here you go adam

That is one fine looking Durango :)

Here's some more photos:

I see your using carbon shock towers. Any particular reason?

Looks very very nice though :thumbsup:

21...?!

As the Orion servos....

savox/spektrum

carbon towers have more holes for tuning than the standard plus with 5mm thick carbon its not going to bend. add that to the go faster effects carbon gives anything its applied to an you got a winner :thumbsup:

Thanks for the photo's Adam they're great. Looks like a really nice job on the build. They'll make good reference when I start my build too. Can't wait..

:thumbsup:

Thanks :thumbsup:

Yeah, 21! 21/60.
Ryan Lutz runs on a 22, but the yanks have slippy dirt where traction is not as high as carpet... So his is a little less eager on low throttle.

Lighter and coupled with the all black and orange feel I had going on I reckon it's about a second a lap faster. :D

Any idea when the manual for the DEX408 will be available on the TD website? Also, I'd like to order some different size pinions for it, do we know what pitch the spur/pinion is (MOD1 / 32dp etc)?

Regards,
Pedro

mod1 i wud say

i have a mod1 21t I will not be needing, PM me if anyone requires it, brand new.

I've got most of my bits now, apart from the kit! should be coming soon hopefully..

Still wondering about tyres, can anyone recommend some tyres for use on packed mud / loose dirt?

Thanks :thumbsup:

I'm considering 2 packs of these:

DBoots - Multibyte 1/8th Off Road Buggy - Compound A

but being new to 1/8th I don't really know if they're the right tyre for the job..

The new BETA tyres from Nemo Racing have been come highly recommended. I've yet to try them myself yet though...

Wow, whats the internal gear ratio? I normaly use 15T max for the Mugen/Kyosho/Serpent etc. ANd thats with a 2050kv motor.

Im not so sure for dirt, I use them great tyres but I will be running purely astro.

try some AKA tyres.

The internal ratio is the same as the DNX408.
The gears are indeed MOD1, this seems to be the 'industry standard' for this class.
The 21 I have is currently on the end of a 1900 motor, I'm not sure what to run on a 2050kV motor. Working on simple ratios, I'd probably start out on a 19T.

Dirt tyres, there's a whole host of them out there. The best 'all round' option would be Something like M3 Crimefighter or AKA CityBlock or Impact. They're easy to come by and will work well on 90% of tracks...

So, when are they coming?:drool:

I see the US customers are starting to receive their kits over on RC Tech forum. Seems a shame that the US customers get theirs first, I thought Durango was a UK company? :(

Some of the US customers are starting to race their cars now...

Yes, it is a shame. We got the DNX408 first so I guess it's their turn. The electric market is evidently already pretty big in the US compared to the UK.

thought we were meant to have them yesterday. the wait is killing me got all my bits ready to build it but no car :mad:
