Racing Fighter Build

Recommended Posts

EDIT: this thread has been rebuilt, having transferred the photos from photobucket to Flickr (12.01.2017)

 

Ok, so this started out as a 'build an alternative to the Mad Bull in the form of a monster buggy' concept, using a Racing Fighter DT-03 as a base (inspiration: see @ThunderDragonCy DT-03 build, it's awesome).

What actually happened was I kind of fell in love with the Racing Fighter and decided to build it as per the original design, albeit with a range of hop-ups, and an odd personalised mod here and there....  Here goes.

 

So this little badger turned up in the post. An absolute steal from Tamico, CVA dampers and Torque Tuned motor included.

 

IMG_3848

 

Love the design and format of the chassis and frame:

IMG_3855

 

 

 

First move is to connect the two halves of the chassis. Quite like this design, 3 screws to hold this together:

IMG_3879Dt03

 

 

 

Front suspension brace attached. Hop up coming here soon:

IMG_3884

 

 

 

On to the servo build. Savox Digital SC-1251MG is servo of choice here:

IMG_3887

 

 

 

To be paired with a GPM Racing Products servo saver. Looks more like just a servo steering piece to me, not sure how this constitutes a saver:

 

IMG_3893

 

Servo saver mounted with ball studs to receive the steering arms:

IMG_3892

 

 

Hop up item. GPM servo mount. Couldn't find silver for love nor money:

 

IMG_3893

 

IMG_3894

 

 

 

First time I've used a dedicated servo mount. This is awesome, the servo feels rock solid on the chassis. Tight fit of the servo to the mount also:

IMG_3896

 

 

Servo saver mounted to the servo, using my trusty servo tester setup to ensure servo saver is mounted at absolute centre steering on the servo head. Awesome little piece of kit for very little outlay:  

IMG_3901

 

IMG_3902

 

 

From servo to steering. I plan to install the DT03 turnbuckle set. First time using these:

IMG_3903

 

 

Turnbuckle steering arms fixed to the servo:

IMG_3906

 

 

And installed into the chassis. Love the central design of this, with the angled position of the servo:

IMG_3907

 

 

And on to the front suspension. Another hop up here. This is the GPM front aluminium suspension mount, replaces the plastic piece:

IMG_3910

 

IMG_3911

 

 

With lower front arms mounted:

IMG_3912

 

 

Installed to chassis:

IMG_3914

 

 

And cover by front skid plate. Love the design of this front suspension mount assembly:

 

IMG_3915

 

IMG_3917

 

IMG_3916

 

 

 

Next, on to the front wheel c-hubs. A hop up here, aluminium hubs from GPM:

IMG_3919

 

Beautiful looking piece of kit. Have gone for silver all round where possible:

IMG_3920

 

And not forgetting the front knuckle arm hop up, also GPM:

IMG_3922

 

Installed ball studs for steering:

IMG_3924

 

The completed assembly at the end of the front arms. Also shown here is the turnbuckle upper "arm" hop up, which adjust wheel camber:

IMG_3946

 

 

IMG_3942

 

These turnbuckle steering link things can hurt thumbs when assembling, get some good pliers and a flat faced  plier, makes it real easy:

On to the rear gear box. Decided to try out AW Grease as recommended on this forum, to achieve a semi limited slip differential affect:

IMG_3997

 

Applied to the differential gears (reverse callipers recommended..!)

IMG_3998

 

Installed in the main differential gear case:

IMG_4007

 

And with counter gear, all ball raced:

IMG_4002

 

Installed in gear box housing:

IMG_4005

 

 

Completed gear box:

IMG_4010

 

On to the motor. A brushless sensored speedpassion 13.5t.

IMG_4011

 

IMG_4012

 

 

Mounted into gearbox, motor set to the 17t pinion orientation:

IMG_4016

 

Spur gear fitted to gearbox, and 17t steel pinion fitted to motor:

IMG_4019

 

IMG_4018

 

 

Gearbox fully closed up:

IMG_4021

 

 

 

Rest of build to follow tomorrow night.

Lower arms mounted to the rear gearbox. Upper arms not required as these will be replaced with the turnbuckle arms:

IMG_4023

 

IMG_4025

 

 

 

Said arms from the DT-03 Turnbuckle set. These are a right pain to tighten up equally! I like the way the screw direction is opposite at each end to allow the arm to get longer or shorter:

IMG_4026

 

 

Next item to install, hop up Gear Box joints. This metal part replaces the plastic part N2. This is the main drive from the gearbox:

IMG_4028

 

Metal driveshaft replacement part for N3, 3 inch dogbone.

IMG_4034

 

The drive shaft links between the gear box joint and this part, the TG10 Wheel axle:

 

IMG_4033

 

The wheel axle sits in the GPM aluminium rear knuckle arms which carries the rear wheel:

 

IMG_4032

 

 

So here you can see the gear box joint mounted to the gearbox on the right, and the wheel axle and the rear knuckle arm on the left. Driveshaft not yet installed:

IMG_4035

 

 

Getting the driveshaft installed requires you to hold the knuckle arm in place and slot the shaft in....

IMG_4036

 

With some grease, I used molybdenum grease (not kit standard but used on the HotShot for example), got this from Tamico. Applied to the gear box joint and the wheel axle:

IMG_4030

 

So putting that lot together looks a bit like this:

IMG_4037

 

Again, the stock plastic upper arm is not required, turnbuckle arm replaces it, providing adjustability for camber.

 

(will have to post rest of build tomorrow.... Tamiyaclub website and photobucket website are playing up big time tonight, taking ages to post stuff - and I just lost a big bit of the post.... :(  )

Ok so all suspension arms on, front and rear:

IMG_4045

 

IMG_4047

 

So now onto the shock towers - sorry, "damper stays". Another hop up here, carbon damper stays. Mmmmm.... lovely carbon:

IMG_4050

 

Front is top, rear is below:

IMG_4052

 

 

 

Front damper stay:

IMG_4065

 

Rear stay:

IMG_4079

 

 

Another nod to ThunderDragon, I checked out the DF-03 spring set, very nice hop up pack indeed. These are to go on CVA 2 mini (front) and short (rear) shock bodies.

IMG_4053

 

IMG_4058

 

 

IMG_4057

 

^^^Very useful diagrams, these ^^^

 

When building the shocks, I went with three hole pistons front and rear in the end:

IMG_4060

 

Black springs front (stiff), gold rear (medium).

One minor mod you'll see in the pics above is the angle up of the rear wing, to give it a bit more of an aggressive, more old-school buggy feel:

IMG_4222

 

 

This was achieved using this piece, the stock rear gearbox bracing arm, part C3. This was a left over as I replaced this with an aluminium hop up as mentioned earlier in the thread:

IMG_4184

 

Made some holes in the rear wing bracket, traced the C3 holes onto M5, shown in two white dots below:

IMG_4185

 

 

 

And drilled M5 and M4 at the same time (vice used to hold them together), and then fixed the C3 part to it:

IMG_4187

 

 

IMG_4205

 

 

This pushes the wing part upwards when mounted to the wing mount:

IMG_4258

 

IMG_4259

 

Just used a 3mm drill to create the two holes in parts M4 and M5, and two m3 bolts and two m3 nuts to connect the two pieces. Nice uplift at the rear end...!

IMG_4250

Thanks guys, really enjoyed building it. Big thanks to Thunder's detailed build thread, learned a lot from him. 

Will need to give it some stickers.

I also have a second body I'll try in an orange colour. 

Then I will run it...!

I'll try to create a consolidated list of the components and hop ups used in this thread soon.

I quite like the look of these. Not had a 2wd buggy since my first which was a Hornet.

Best leave it til after I get my boys some cars though.

Or I could go for red body, silver roof, white wheels, a few number 3 stickers, and make it 'project RacingShot'....!

Excellent looking DT03, just as good looking as that new chrome version they released!

Yeah, I searched high and low for that component; Europe, US or Asia, no joy however. Sometimes you can't let one hop-up hold up the whole build, so I had to ignore it on this one. In a mad irrational burst of purchasing insanity,  I sort of ordered another Racing Fighter kit right after finishing the paint job of this one on Sunday night ...

Nice build I've broken or bent quite a lot of my gpm aluminium parts and replaced them with the kit plastic parts again. The aluminium servo mount makes a big difference to the stiffness of the front.

Have you broken the gearcase where the arms connect? I have broken it four times since january, prior to that went a year with no issues. 

I have all the tamiya hop ups with no issues. GPM parts i have rear knuckles, hexes, c hubs and front rocker arms never had issues. I had the gpm dogbones but changed to tamiya universals. 

I can vouch that jazzride aluminum is junk

Fingers crossed I've had no rear end breakages. I bent the front hubs and broke the shock tower mount.

Ok, the second Racing Fighter kit turned up. Now I can start my Mad Bull Alternative project in earnest!

Will do the Mad Bull alternative on a separate thread to keep this one simple. Looking forward to that one...!

 

On this car, I made a small adjustment to the rear shocks: I replaced part X1 with X2 to make the shocks longer- I think I overtightened X2 the first time around and damaged it, so had to make do with installing X1 until I could get more X2s. 

 

Went from top top to bottom:

IMG_4525

 

This X2 part was troublesome as I wasn't sure how much thread was supposed to be left visible. See below, this feels like I haven't installed it correctly but it doesn't seem to go on further than this:

IMG_4527

 

With the longer shock, the rear of the car now has a lot more clearance. Have subsequently corrected the amount of thread that goes into the plastic.
