Dingo Class 2

[tgenial58]

Hi

It was a long time I haven't a new rig
Going on a walk with protos of 5 or 6kg, it's nice, but I finish the exits with the beast that breaks me, assembled in rucksack due to breakdown

The objective is to:
to finish the walks :P
rig is as light as possible (that's the reason of dingo body)
1.9 tires mounted
To run as long as possible with a 3S 4,5Ah lipo (less than 1 hour is sad)
And I don't want a urban 4x4


material choice:
First idea was CF 3mm, but budget is a little high, so I prefer take 4mm alu sheet plate, less expensive
Skid and front reinforcements are in 8 mm delrin
For large reinforcements plates, I use 3mm Dibond (alu, PE, alu sandwich) which is really light and enough strong
I've tried to do the rails with it, but it wasn't the good choice in front of rock or tree

Front axle passage is raised
the final version of frame, with 4mm alu



Dibond for lateral reinforcements



Skid delrin 8mm*



Dibond lipo support



rear plate



For electronic parts, I want to stay on a realist scale, so I use 15kg steering servo. If it doesn't want to turn, I'll go reward, as in the real life
It is mounted inside chassis rails




I've found 60A continu (320 max) brushed ESC on ebay for ridiculous price (12$, included shipping)
TGS LEDs bar 3S waterproof





It does the job


For mechanical parts, I use:
Axial scx10 front axle
axial scx10 gearbox with 24/87T ratio and 45T integy motor
rear axle alu/steel from my workshop, with scx dif
axial transmission shafts
Panhard system




front upper links support




exactly at the right position



4mm steel rod for front links
8mm delrin for trailing arms



Gmade 90mm shocks for front
130mm shocks fo rear

front wheels: 2mm CF with delrin beadlocks
rear: I hadn't enough screws to mount CF, so axial took place




1.9 SDI**trail doctor XL (not the best )

delrin body mount supports



a small lifting of front face



cover top made in old tent







it's cool in a kitchen, but mud is really better



lights are installed
6V plate for front and rear light and for counters

3S LEDs bar.
10 cm is enough, I believe





counters



and In the light of day, we can see the schnorkel



See you soon for the next step; the video

Hey good job. Truck looks good

[tgenial58]

front is finished

Radiator grille (I wanted to keep a memory of the former owner ), bumper and winch are mounted
bumper is made with 2mm CF, to reduce weight
winch is powered by a small 2S esc (20A) with its own lipo and drived on the third channel by the gt3B's trim button











Tamya spray is ordered to renovate painting

[Desmo]

Like your build. Whats the total weight?

[tgenial58]

Ready to run, it weights 2732g (6.023 lbs) with 340g (0.75 lbs) for the main lipo and 50g (0.1 lb) for winch's lipo

Hi!
So, after trying the ESC, it's a s**t: no power in reverse mode, no punch...
It works, but it's good to be crazy

Then I've changed it for a 13.5T brushless sensored and a hobbywing ESC clone, 3S 120A
I've replace pinion and spur gear by 32Dp 12T pinion and 58T spur gear.
I've to reverse gearbox and motor, due to the sensored motor.

I've put 50% expo on Tx, no punch on ESC and this works really good
Smooth low speed with torque and a really good max speed, with good response on acceleration
Ready for U4 races





Wheels are transformed in 3 parts, it's more "agressive" design and enlarge the tire, too thin so they dig instead of grab in soil





My friend Cab has painted and given me the pilot's head



A small servo will move it, mixed with steering in the future

Next test on thursday

Hi!
Here the new short video with my friends Alfi31, with his wraith (OD, UD, brushless motor) and Cab77, with his bomber (35T torque master).

[tgenial58]

And the last changements, before this run

I have reversed steering arms and build a new part for servo link, to have ackerman effect in good way





and the new steering link, behind the axle



I had to grind the end of steering arms on knuckles to pass the axle's links/shocks supports. And I had changed original Chubs screws by TBHC to earn 1 or 2°

Hi! To close the scale season, the last movie of the year

[tgenial58]

Happy new year


Wouhou!! my new scale tires are arrived, after 2 months of waiting
They are just little bit bigger
Rest to test them on terrain









And perhaps you have noted the roll bar on the rear, fixed under the chassis.
It's mounted on threaded shaft to turn freely. Really cool to not destroy chassyis and body

Not 35t but 27t Torquemaster yes !

Hi!

A new part for my dingo
I couldn't stay with plastic roll cage then this morning, I've attacked to build my roll cage
A TIG, some 6mm steel tubes and let's go
This is the result: 220g, that's enough











Remains to paint it, to add some attachments for sand plates, ground anchor and it will be good

[tgenial58]

no problem

[tgenial58]

Today, I'm gone have a ride
I had raised the suspension because the tires were touching the body.
but it's really not good.
Transmission shafts have too much angle.
then I decided to do some space in the body and to go down the frame
And I changed the CF rims to alu, more scale













it misses jeep fenders

[tgenial58]

Hi!
Some new changes, after a hard training with lot of damages

A new aluminium bumper, flat with a free tube at the bottom to roll over the rocks
An eye has to be replaced



A new position for the winch and the servo
they step back, behind the body. I returned the steering arm and now, I have a good attack angle



I installed steel sliders to protect the body

Hi!
