ALEXKYRIAK 1046 Posted June 5, 2017 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. Love the design and format of the chassis and frame: First move is to connect the two halves of the chassis. Quite like this design, 3 screws to hold this together: Front suspension brace attached. Hop up coming here soon: On to the servo build. Savox Digital SC-1251MG is servo of choice here: 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: Servo saver mounted with ball studs to receive the steering arms: Hop up item. GPM servo mount. Couldn't find silver for love nor money: 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: 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: From servo to steering. I plan to install the DT03 turnbuckle set. First time using these: Turnbuckle steering arms fixed to the servo: And installed into the chassis. Love the central design of this, with the angled position of the servo: And on to the front suspension. Another hop up here. This is the GPM front aluminium suspension mount, replaces the plastic piece: With lower front arms mounted: Installed to chassis: And cover by front skid plate. Love the design of this front suspension mount assembly: Next, on to the front wheel c-hubs. A hop up here, aluminium hubs from GPM: Beautiful looking piece of kit. Have gone for silver all round where possible: And not forgetting the front knuckle arm hop up, also GPM: Installed ball studs for steering: The completed assembly at the end of the front arms. Also shown here is the turnbuckle upper "arm" hop up, which adjust wheel camber: These turnbuckle steering link things can hurt thumbs when assembling, get some good pliers and a flat faced plier, makes it real easy: 3 Share this post Link to post Share on other sites
ALEXKYRIAK 1046 Posted June 5, 2017 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: Applied to the differential gears (reverse callipers recommended..!) Installed in the main differential gear case: And with counter gear, all ball raced: Installed in gear box housing: Completed gear box: On to the motor. A brushless sensored speedpassion 13.5t. Mounted into gearbox, motor set to the 17t pinion orientation: Spur gear fitted to gearbox, and 17t steel pinion fitted to motor: Gearbox fully closed up: Rest of build to follow tomorrow night. 7 Share this post Link to post Share on other sites
ALEXKYRIAK 1046 Posted June 6, 2017 Lower arms mounted to the rear gearbox. Upper arms not required as these will be replaced with the turnbuckle arms: 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: 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: Metal driveshaft replacement part for N3, 3 inch dogbone. The drive shaft links between the gear box joint and this part, the TG10 Wheel axle: The wheel axle sits in the GPM aluminium rear knuckle arms which carries the rear wheel: 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: Getting the driveshaft installed requires you to hold the knuckle arm in place and slot the shaft in.... 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: So putting that lot together looks a bit like this: 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.... ) 3 Share this post Link to post Share on other sites

ALEXKYRIAK 1046 Posted June 7, 2017 Ok so all suspension arms on, front and rear: So now onto the shock towers - sorry, "damper stays". Another hop up here, carbon damper stays. Mmmmm.... lovely carbon: Front is top, rear is below: Front damper stay: Rear stay: 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. ^^^Very useful diagrams, these ^^^ When building the shocks, I went with three hole pistons front and rear in the end: Black springs front (stiff), gold rear (medium). 1 Share this post Link to post Share on other sites
ALEXKYRIAK 1046 Posted June 7, 2017 Ball studs mounted to damper stays: this is the top of the rear: Long ball stud screw goes into rear lower arm: Rear shock installed: Front shocks: Wheels and tyres, tried ThunderDragons Schumacher CAT block tyres mounted onto the kit standard wheels, because they look awesome on stock wheels...!: Installed to chassis: 2 Share this post Link to post Share on other sites
ALEXKYRIAK 1046 Posted June 7, 2017 Front wheel inside detail with front C-hub and knuckle arm: Rear inside hub detail: Time to test fit body: ime to About to paint.... still can't decide on a bl**dy colour scheme.... only had a month to choose....! Went stealth black in the end....! Will sticker it up at the weekend....! 8 Share this post Link to post Share on other sites
ALEXKYRIAK 1046 Posted June 7, 2017 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: 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: Made some holes in the rear wing bracket, traced the C3 holes onto M5, shown in two white dots below: And drilled M5 and M4 at the same time (vice used to hold them together), and then fixed the C3 part to it: This pushes the wing part upwards when mounted to the wing mount: 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...! 7 Share this post Link to post Share on other sites

ALEXKYRIAK 1046 Posted June 8, 2017 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. 3 Share this post Link to post Share on other sites
Peter_B 997 Posted June 8, 2017 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. Share this post Link to post Share on other sites

One of the only upgrades i dont have for my dt03t 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 ...

gary1365 90 Posted June 8, 2017 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. 1 Share this post Link to post Share on other sites

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 Share this post Link to post Share on other sites

ALEXKYRIAK 1046 Posted June 18, 2017 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: 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: 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. Share this post Link to post Share on other sites
