Team [HOONIGAN]'s DRX(s) RPMJ showed me a used Kysoho DRX on ebay a few weeks ago. We had it listed in the 8th scale open rally class for our series, but I never thought a ton about them being a nitro and a difficult to get Kyosho car. I started readying around and looking at dimensions and learned that it is actually bigger then the HPI WR8 in every dimension. It is based on a 1/8th scale buggy, surprisingly light weight and parts are easier to get then I originally thought. Specs: Kyosho 1/9th scale DRX rally Length: 563mm (22.17 inches) Width: 260mm (10.24 inches) Height: 187mm (7.36 inches) Wheelbase: 316mm (12.44 inches) Tread (F/R): 215mm / 215mm (8.46 inches) Tire(F/R): Φ93×38mm / Φ93×38mm Gear Ratio: 8.86:1 Weight: 2,600g (approx.) (5.73 pounds) HPI WR8 (supposed 1/8th scale) Chassis length: 485mm ( 19.09 inches) Width: 227mm (8.94 inches) Height: 172 (6.77 inches) Wheelbase: 300mm (11.81 inches) Tamiya DF03RA (1/10th scale) Length: 407mm (16 inches) Width: 186mm (7.32 inches) Height: 155mm (6.1 inches) Chassis weight: 1,112g (2.45 pounds (no electronics) It starts with one. Kyosho DRX Ford Fiesta. Comes as a RTR nitro. The first thing I did was pull the 18 motor out and all the nitro parts. There was a list posted on Infernosonly.com with the parts needed to convert this to brushless, but as I quickly found out many of the parts were not needed. Of the 5 parts that are supposed to be used for the conversion I have only used two, the Electric motor mount and the battery tray. Here is how it started http://i34.photobucket.com/albums/d1..._0642small.jpg The mod parts http://i34.photobucket.com/albums/d1..._0640small.jpg Ride height with the Nitro setup http://i34.photobucket.com/albums/d1..._0644small.jpg Suspension fully drooped out http://i34.photobucket.com/albums/d1..._0645small.jpg Full compression the body touches the ground. Rear end http://i34.photobucket.com/albums/d1..._0646small.jpg Front end http://i34.photobucket.com/albums/d1..._0647small.jpg The front and rear light buckets are LED ready, full 3 dimensional light areas. http://i34.photobucket.com/albums/d1..._0649small.jpg Size comparisons with a 10th scale rally car. http://i34.photobucket.com/albums/d1..._0650small.jpg http://i34.photobucket.com/albums/d1..._0652small.jpg http://i34.photobucket.com/albums/d1..._0655small.jpg How it comes http://i34.photobucket.com/albums/d1..._0656small.jpg Motor out http://i34.photobucket.com/albums/d1..._0659small.jpg Radio box, fuel tank, dual brakes all out http://i34.photobucket.com/albums/d1..._0660small.jpg The oil filled center diff. http://i34.photobucket.com/albums/d1..._0670small.jpg The electronics already in. ;D http://i34.photobucket.com/albums/d1..._0669small.jpg The motor and pinion are just for mock up I have a Mamba Max Pro and 2400KV 550 can SC system going in. Still thinking about a better servo to put in. I will be using this Max amps 5450MAH 3 cell battery. I still need to rebuild all the differentials with better oil and add a few gears to the inside of the center diff. Probably going to make an under body as well. Hopefully the motor, ESC and MOD1 pinions show up tomorrow so I can at least take it for a short test run. I will get some more updates soon and progress on DRX #2 soon. |
Re: Team [HOONIGAN]'s DRX(s) Thats bada$$! Cant wait to see video! |
Re: Team [HOONIGAN]'s DRX(s) Ok, here we go...:mrgreen: Figured you would've got the Subi ??? |
Re: Team [HOONIGAN]'s DRX(s) May be off topic, but since this car is based on a buggy, would it be gt8 legal? |
Re: Team [HOONIGAN]'s DRX(s) Hmmmmmmmmm... That's pretty cool!! :ror::ror: |
Re: Team [HOONIGAN]'s DRX(s) i want one but only if it was electric i have never had luck with nitro i wanna see more of the suby next to it |
Re: Team [HOONIGAN]'s DRX(s) why did i have to look in here..."thumbsup" |

Re: Team [HOONIGAN]'s DRX(s) Here is some more progress Here is the differential gear I was talking about before, it comes with 2 spider gears inside, but to add to the durability of it I added 2 more gears bringing the total to 4. The center diff and each axle diff has an identical differential only the ring gears are different from the center spur. http://i34.photobucket.com/albums/d1..._0679small.jpg I never realized how big a mod 1 pinion was til I put it on. This is a 15 tooth mod 1, which is about the size of a 20 tooth 32 pitch pinion. http://i34.photobucket.com/albums/d1..._0680small.jpg The tires are pretty scale and are surprisingly soft. Kyosho also offers three different inner foams for the tires from hard to soft. http://i34.photobucket.com/albums/d1..._0681small.jpg The front foam bumper is really large and soft, should absorb the impacts really well. Kyosho was actually really smart and it is raised up to keep it from rubbing on the ground. http://i34.photobucket.com/albums/d1..._0682small.jpg #1 as a roller http://i34.photobucket.com/albums/d1..._0683small.jpg #2 almost a roller http://i34.photobucket.com/albums/d1..._0684small.jpg #2 has a Tekin 5.5 redline sensored motor for starts. It is also using the recommended conversion chassis, whereas #1 is using the stock chassis which I drilled for the motor mount and battery tray. #2 also had to be drilled for some parts, but the motor mounting holes were already on the chassis. http://i34.photobucket.com/albums/d1..._0688small.jpg http://i34.photobucket.com/albums/d1..._0693small.jpg The kids together. http://i34.photobucket.com/albums/d1..._0689small.jpg Here you can see how tight the tolerances are between the battery and spur gear. There is a lot of room on the chassis for mounting everything, but the chassis is not quite wide enough to keep the entire battery tray on it. http://i34.photobucket.com/albums/d1..._0690small.jpg You may also notice that with the electric conversion chassis on #2 the motor is mounted on the other side of the differential. http://i34.photobucket.com/albums/d1..._0694small.jpg For reference the bottom of #2 http://i34.photobucket.com/albums/d1..._0695small.jpg The bottom of #1, to me this is the largest difference between the two chassis'. Notice the large holes in chassis #1 (blue). http://i34.photobucket.com/albums/d1..._0696small.jpg Thats it for tonight. Enjoy. Ty |
Re: Team [HOONIGAN]'s DRX(s) SWEET!!! Hmmm...what to do now, can't let John drive his rally alone. :mrgreen: |

I got impatient before my SCT 2400kv combo showed up and threw a mamba max 2 cell lipo and Traxxas BL motor in. This is what I got. Kyosho DRX ELECTRIC - YouTube More photos of DRX #2 http://i34.photobucket.com/albums/d1..._0697small.jpg Both DRXs got Savox 1258TG servos. At 6 volts are 166 oz of torque and a .08 speed. http://i34.photobucket.com/albums/d1..._0698small.jpg The electric conversion chassis has the steering servo relocated, but we decided instead of moving all the steering linkage around we would just line up the stock chassis and put the servo in the same location as stock. http://i34.photobucket.com/albums/d1..._0699small.jpg http://i34.photobucket.com/albums/d1..._0702small.jpg Both ready to run http://i34.photobucket.com/albums/d1..._0708small.jpg Hard to tell them apart, I started the next step and started setting the body apart. http://i34.photobucket.com/albums/d1..._0721small.jpg http://i34.photobucket.com/albums/d1..._0728small.jpg http://i34.photobucket.com/albums/d1..._0732small.jpg http://i34.photobucket.com/albums/d1..._0733small.jpg http://i34.photobucket.com/albums/d1..._0738small.jpg More later, RPMJ and I are just blazing through these builds!:ror: |

The way I drive it definitely needs one. The body is also more brittle then we had hoped. I already have several cracks starting to form, I dumped a lot of Shoo Goo on the body and so far it seems to be helping. Im trying to figure out an underbody now. Either something custom made or figure out if an Inferno body will work. |
Re: Team [HOONIGAN]'s DRX(s) More rally goodness! Awesome cars. |
Re: Team [HOONIGAN]'s DRX(s) Is this whole set up similar to the inferno? I get you on the WR8 not really being 1/8 scale. It's more like the old super nitros 1/9 scale. wonder if the proline rs10 or whatever body would fit this. if so cheaper replacements than from kyosho. |

Re: Team [HOONIGAN]'s DRX(s) I forgot all about having my camera with me yesterday when you were driving it. Wish I had taken some jump shots. Very cool though. You and Rodney are a bad influence on everyone :flipoff: |
Re: Team [HOONIGAN]'s DRX(s) very cool indeed! |
Re: Team [HOONIGAN]'s DRX(s) this is friggin awwessommmmmeee, love rally. |
