A new BERG Tracer V3

[tgenial58]

HI

He's arrived and is fonctionnal finally..

This is a complete kit with wheels, ordered at TCS in april, and electronic parts come since few days.

technical parts:
GT3B hacked by Francis63 ( RC Crawler France during the "BIG", the scales and crawlers meeting in France)
2 TEKIN FXR
2 INTEGY 45T motors
BEC Castle Creation programmed in 7.4V
I took 3 Lipos 3S Turnigy de 800 mAh to play some hours
To test the Berg, I put Savox SC 1268SG 25 kg wich wil be replaced by Hitec HS8385TH Premium HV Monster Torque Magnet 34 Kg,




I cut short ABS part to protect and fix Lipo







I try to put on front a maximum of equipments





Like that, I can modify quickly ESC tuning









And the decoration





After 3 hours of unsuccessful tuning, I come back on radio and I succeeded to tune the GT3B with neutral, throttle and quick tune on ESCs. After, I programmed DIG and mixing
First surprise are pins on front axle. The rings move and pins go out. I put some threadlocker glue to try

I try berg tires, but they are too strong. So I change them to losi rock claws, waiting 2 boss claws to the rear, and it's really better

I need to clock the front axle, but I want to try it now, because it's too long time I'm dreaming a MOA

I made 2 Pb weights to equilibrate at 60/40, fixed with hot glue

Félicitations, beau build

I should receive mine soon.

Do you like the wheelspin with the 45T ?

A+

Hi

Thank you
I find it's a good deal: you can go very slowly, but if you need, you have some ressource .
I try one wich is mounted with 35T, it's need more precision to drive slowly but to do junctions between 2 gates, it's better.
On the other hand, I wouldn't try a 55T. I think it's too short

[tgenial58]

Hi

Today I'm gone in old carriere of rocks to really try the Berg
I forgot my camera's SD card (but it's better than forget transmitter )
So I used my phone to take pictures

[ncampos976]

looks good. i have a extra v3 chassis if your looking for one

[tgenial58]

Hi

Thank you, but it's new ( for the moment ) and I hope keep it a long time. But I keep the information in case

[tgenial58]

Hi

I hope you enjoy

I find it amazing
And it's just the beginning

[tgenial58]

Hi

Some news from the berg

I ordered 2 boss claws for the rear.



but they hadn't the same diameter as rock claws, so I had to change them by the HB rover white

and it's really better



At the last trip, I burned the savox. 25Kg is not enough. So I ordered a Hitec 7950TH, plugged in 7.4V and it's really good, now!



I find the hitec is very hot, but I don't know if it's normal or if there is a problem. I hope that not finish like savox.
The next step is to clock front axle, but I glued screws and it's difficult to extract now and I have to realise new servo support

[tgenial58]

Hi

it's done
I clocked my axle yesterday.
Thank you Mr Berg, because it's really easy to do




I had to cut a little part from hub




I changed position of steering arm and now, servo does not heat







Now, I'm ready to run

[Quiel]

Can you post pics on how you wire the BEC setup with the two ESC.

[tgenial58]

Hi



I used an old Rx to get pins and an old servo plug to make electronique plate

Hi

Some news
New Crawler Innovations double deuce foams soft for front and rear




Before




and after



And I made a servo protection with 1.5 mm alu



To be conform with crawler rules, I had to make 2 side panels




And a little video

[tgenial58]

Hi

Some modifications are gone

Shocks and links position



I have modified links positions



and made a rear upper support



I turned delrin tubs for rear. I win 28g










So I have tried that

BERG Tracer V3 St Féréol

And when I come back, I find in my letterbox an order from Voodoo tires

[tgenial58]

Hi

And some modifications more

I opened links on supports



And I add nut between shocks and body, because I hate when shock head hurt body.
It's unbelievable. I get 1 or 2 cm more and I had to unscrew the last top screws for the uper links







I had weigh the rear support plastic links





I earned 2.6g. I am surprised by the difference

And, finally, I turned my wheels and earned 20g per wheel







I believe I'll go test the modifications this afternoon

[tgenial58]

Hi

And some modifications more

I turned new wheels in polycarbonate with 1 side beadlock

internal ring


inside ring



external ring









A good gain

it miss hubs, but they're coming

And the most important modification: the chassis
I used aluminium in 4mm





When I'll valid that, I'll built them with carbon fiber, because they weigh 7g more than the original carbon plate but I think the space gain beneath chassis is really efficiently

I moved lower links at outside of upper links

[tgenial58]

Hi
Here the following

I made hubs: this is a mix between VP hubs with drilling dimensions and RC4WD because I mill pin mount







I change upper links
I use alu tube in 6x1mm, wich is tap in M5
I turned screw in M5 at one side and M4 at the other to put in rod end









I can get out front wheels weigh and now I 'm at 2,3kg

hi
i realy like the plexy beadlock
but i thinck i will try to do the same as the d-lux in carbon

[Quiel]

I am using a Futaba 4PL with a 4 channel receiver. I am also running dual ESC. Servo on channel 1, ESC on channel 2 and 3 with middle wire pulled off the plug. BEC on channel 4. I am able to turn my steering but not able to get power to the front and rear motor. Any suggestions?

it s perfact!!
