Pro-Line Project Garage: Transforming Axial’s RR10 Bomber into a Scale Rock Racer

 

RR01-1024x647

Axial’s RR10 Bomber Platform has burst onto the RC scene, quickly becoming one of the most sought after rigs in a short period of time It has captured the thrill of ULTRA4 Racing / King of the Hammers events. It’s a nicely balanced 1:10 scale rig that lends it self to all sorts of detailing and Upgrades! Pro-Line Racing recognizes this and set out on a quest to build our version of the Ultimate Rock Racer. We are proud to offer exciting products to upgrade this awesome platform into the rock racer of your dreams as well as show you how to put it all together into one awesome package.

RR02

Tires / Wheels: New Products
To start, Pro-Line’s new BFGoodrich licensed scale crawler tires were selected for this project. These awesome looking KR2 Rock Terrain version tires are almost a year in development and testing. In our initial release, we will be offering them in both 1.9 and 2.2 sizes. Shown here on the truck are the 10119-14 KR2 2.2” versions mounted to a set of our 2757-15 Denali 2.2” Black Bead lock wheels. The black paint finish was stripped off the bead lock rings with Dupli-Color ST100 Paint Stripper and then polished to a Mirror finish with automotive grade metal polish. Gear Head GEA1120 M2 X 8mm Scale Silver hex bolts were added to hold the bead lock rings on for more scale realism.

Wheel Mounting
The 2.2 Denali Wheels are not a direct fit to the RR10 Bomber hex drives. They are not a direct fit due to the installation of a raised step hex’s on the axle shafts. There are however a few options to solve the hex dilemma. The quickest way is to drill out the center of the wheel to the same diameter of the hex step shoulder. You would then use the Axial AXA1090 4.8X14 Black wheel washers in between the face of the wheel and the wheel nut. For more advance builders, you can grind off this step on the face of the hex for the wheel to fully seat on the hex (which is what I did) or you can install non step faced aftermarket hex drive.

RR05

Shocks / Suspension
For high performance in both Crawling and Desert Racing a set of our big bore 6308-31 Pro-Spec Shocks were selected. The stock yellow springs were retained for the front while stiffer Purple and Red Springs were acquired for the Rears from our 6308-22 Rear Spring Assortment. The spring assortment allow for finer tuning of the suspension, based on the running conditions of the vehicle. Vanquish Titanium Links were used on the Front and upper part pf the rear Suspension.  The Lower Rear links were retained and a set of Axial AX31245 Lower Link plates were added once the Gold Anodized finish was removed and the plates polished to a mirror finish.

Axle Upgrade
The stock plastic AR60 axle housings were upgraded to RC4WD AR60 Z-A0065 Front and Z-A0066 Rear Aluminum axles. Grip Fab Stainless Spools and Axial AX30395 HD Beveled gear sets were added to the front and rear. A Z-S0832 XVD axle set was added in the front for tighter turning and higher strength. The axles were finished off with various RC4WD, Grip Fab and Team KNK Hardware components which can be found in the Axle Parts list of the Builder’s Parts List section at the bottom of this article.

Transmission / Drive Line
The transmission has been beefed up with a Axial AX31181 speed conversion kit and re assembled with stainless hardware from Team KNK’s RR10 Bomber Hardware kit.

Axial Racing’s optional AX31156 Machined aluminum motor mount, AX31161 32P /64T Steel Spur Gear and AX31164 Machined Slipper Plate Set were also added to the transmission’s upgrade list. Don’t forget to purchase a set of AX31068 Slipper pads when switching to the optional Steel Spur Gear.

RR09

A Holmes Hobbies Puller Pro 540S “Stubby” 2200KV brushless motor and a Trailmaster BLE PRO Waterproof Speed Controller supplies power to the transmission. A Hitec HS5645 MG Digital Ultra Torque Servo was installed for shifting the 2 speed transmission. A SSD 00073 Scale Steel Drive Shaft was added on the rear and the stock front one modified with SSD 00032 Steel Boar Universal Joints and the plastic tubes of the drive shaft was shortened for proper length.

Body
I wanted a custom look to the Cage so it was disassembled, prepped and custom painted with Dupli-Color Automotive Paint; found at most automotive parts stores. For best adhesion, I prepped the plastic parts with rubbing alcohol and did not use a primer making sure the paint dried between coats. This is the best method I have found for painting plastic. Please Note that while it looks good, it will scratch with any rough abuse as it’s a painted surface just like a real car. The cage was the re-assembled with Stainless Hardwar from Team KNK’s RR10 Bomber Hardware kit

RR13RR14RR15

Turning attention to the body panels the stock panels were covered in an awesome Pro-Line RR10 Bomber Skinz graphics kit by Freqeskiz. They have some nice selections and it’s an easy way to add a custom look to you RR10 Bomber or other RC vehicles.

Exterior Body, LED Lighting and Accessories
Let there be light! Yes Pro-Line has some new Super-Bright LED Light Bars. At almost 500LUX, these are just about double the brightness of any other RC LED comparable light bar currently available. The 6076-00 2” bar was mounted up front and the 6276-01 4” Bar was mounted on the roof. The Lights are rated for 6V to 12V power, so you have the option to plug directly into a 3S lipo power source for Super-Bright LED Light.

RR17RR18RR19

Back lit LED Gauges and a 3D printed GoPro Camera from , Exclusive RC were added to the interior for more scale realism (GoPro Camera’s are not lite). These gauges were wired to the same circuit as the 2” and 4” Pro-Line Super Bright LED Light bars. Exclusive RC pre resistor’s ALL of their wired products with LEDs. Their LED lit products can handle anything from 7 volt, all the way up to 14 volts.

RR20

KOH Rear Brake and Safety lights were also installed using a HeyOK KOH Rear Brake / Safety Light Controller LED Kit, Axial AX80103 Rear Light Bezel and Radiator set and 2x of the AX80049 Lens Set (Yellow Clear). The Rear light bezel was screwed to the under side of the Upper Role cage using 2x M2 Self tapping button head screws.

RR30RR21

A working recovery winch was installed on the RR10 Bomber using a WeryMade Servo Winch Plate, Integy Billet Machined Power Winch, RC4WD Warn Z-S1310 Hawse Polished Aluminum Fairlead and Z-S1551 Warn Premium Winch Hook. The winch is controlled by a RC4WD Z-S1092 Warn Wireless Remote / Receiver winch controller since the 3rd channel of the Radio is taken up by the two speed shift servo and the Brake light controllers.

RR22RR23RR24

To add final details, the radiator and fans parts left over from the AX80103 Light bezel parts tree were painted and added to the back side of the interior tray. The stock Axial RR10 Bomber Drivers Helmets are out of Scale. This problem was solved by replacing them with more proportioned units from our PRO2 SC Buggy kit from Parts Tree 6254-02. The helmets and Driver suits were then detailed out from the rest of the black interior tray.

RR26

The fuel cell was painted red and then further detailed. The filler tube was made from Team Associated 7725 Fuel line and the filler valve made from the reservoir part of a older SCX10 AX80029 Plastic shock parts tree. The jack, pry bar and other scale components were pulled from our Rock Crawling Performance Parts (6045-00) in the Crawler section of our web site.

Conclusion:
For Us, The Axial RR10 Bomber truly captures the passion of Ultra 4 Racing and King of the Hammers. It’s been a blast to work on and a great platform to be detailed out! I hope that you enjoyed reading this article and that it can spark an idea for a Epic RR10 Bomber build of you own!
