The Mini Savage Brushless 1:12 finally gained a name! Fresh of the pan from HPI, it has been confirmed that this will be called the Savage XS Flux. Hopefully, this will come off the production line out to the shelves of your local hobby shop before year end.

New for 2011: Hpi Savage XS Flux

New for 2011: Hpi Savage XS Flux

Effectively, this completes the family of Savages, adding a smaller sibling to the existing Savage X, and Savage XL. However, there is still an open possibility for a fifth-scale Savage XX, adding onto the 1/5 scale HPI produce which currently only features the Baja lineup.

The Savage XS Flux will come as an RTR set, including a 2.4ghz waterproof receiver system, Flux brushless setup, with a top speed of 60mph on a 3S Lipo pack. However, the stock package is likely to come with either a 4200mah Nimh battery, or a 2S Lipo battery. HPI is going for a sub-US$300 price to make the Savage XS available to more hobbyists, and for Savage owners to afford yet another Savage into their home garage. The likely price will be US$269-299.

If you’ve been looking high and low for a teaser video on the Savage XS Flux in action, here it is:

If you watched the video, and you’re wondering if the rest of the electronics, like servos, are waterproof too. According to HPI USA, yes they are!

via Kershaw Designs – E-Revo 5T Conversion

By Julian Wong.

No mistake on the title. The design fellows at Kershaw Designs created a kit for Traxxas E-Revo owners to pimp their trucks up to the size dimensions of a HPI Baja 5T. With 8 extra inches in length, this brings the 1/8  E-Revo all the way up to a 1/5 size!

The entire kit retails for $379.99, and includes the 8″ stretch chassis, Traxxas anti-sway bar kit, heavy duty slipper, X-long body posts, 7.5″ truck tires and matching 23mm hubs. You may also purchase the items separately at prices ranging from $99.99 for the 7.5inch tires, to $249.99 for the chassis. While no weight specifications were provided, Kershaw promises that the chassis is lightweight and still allows for quick acceleration. In any case, with the stock Mamba Monster ESC and Castle 2200Kv brushless motor, you can amp up all the way to 6S Lipo and comfortably manage over 55mph!

Kershaw Designs is comprised with a bunch of Electric RC quacks who also have created conversions for the HPI Savage. I’ll be covering that it a future post. Stay tuned!

If you’re looking out for suspension mods for your HPI Savage X, and opt for other options than the HPI Savage X Big Bore Shocks, some of the immediate options that you’d look out for would be “Piggy-Back Shocks” by Integy or Thunder Tiger. If you you’d like to know what Piggy-Back Shocks are, and look like, have a look at these pictures.

HPI Savage X Modifications : Big Bore Shocks

HPI Savage X Modifications : Big Bore Shocks - I use them on my HPI Savage X, and find them great. The shock casing is very bash resistant. I've had several bad crashes but have yet to dent these.. unlike shocks I've had on other cars from other makes, i.e. Kyosho. Also, I find the shock pistons very easy to replace. I've since replaced both of my front titanium-nitride coated pistons.

HPI Savage X Modifications : Piggy Back Shocks

HPI Savage X Modifications : Piggy Back Shocks

“They look very cool!” you must be thinking… However, there has been nothing but negative talk on the use of piggy-back shocks in RC. (click to read) and (click to read) discussions on piggy-back shocks conclude that while the “piggy-back” shock oil reservoirs hold extra oil to keep shock oil temperatures down in full-size vehicles, the shocks in RC models sized at 1/10, 1/8 and even 1/5 don’t even come nearly as hot to benefit from the piggy-back reservoirs. There is NO performance benefit. Various users have even described the Integy-made Piggy-Back shocks for the Savage X as a “load of crap” and a “waste of time”. As such, they seem to be just added weight, and additional items to replace after a bad crash.

What’s left then? Well… there is a growing number of Savage X enthusiasts who recommend LST Shocks from the Team LOSI LST 1/8 XXL Monster Truck. If size is a factor, these shocks are sure to put a stop to any second thoughts. They are HUGE! Just to refill a set of 4 shocks would take two WHOLE bottles of shock oil. Take a look…

LST Shocks Conversion on HPI Savage X

Apparently, they offer great shock dampening, and are even more responsive than those on the Traxxas Revo 3.3 – which is not surprising as the LST is a much larger truck. Choose your springs wisely though., or you may lose the ability to wheelie.

To fit these HUGE shocks on your Savage X, you’ll need a shock mount conversion kit. Some of the popular ones are from Fast Lane Machine or FLM for short (, and Innovative-RC ( Be sure to check those out. While the kits aren’t expensive at all.. just remember one common concept.. “The Bigger they are, the Harder they Fall”, on your pocket, in this case..

I’m going to leave you with a video on Savage X Mods and Reinforcements.. This Savage X enthusiast did the LST Suspension conversion, improvised base-plate protector, suspension arm shaft protectors, and a strong alloy bumper support.

One of the greatest joys in RC racing and bashing is knowing that you have THE most “Bad-ass”, “Pimped out” ride there is. This ain’t my HPI Savage X 4.6. I could only wish that this was available at the time I was shopping about. What you’d be looking at in the following pictures could be the most highly-modded Savage X 4.6 you’d ever see. This has got so much after-market parts on this that it makes the Savage X SS look like a toy. It’s a TANK! Best part, it’s mint condition. “Has never seen fuel” as the owner says.

The owner is looking to let go for $900, or to trade for a good electric 1/8 buggy. Find out more by viewing the thread on, at the following link:

Reviews on Turnigy Trackstar 150A ESC

Posted as above: “Based on posts at RC-monster the internals are a Mamba Monster clone (even though on the outside it looks like a Tekin clone), but it uses lower quality FETs and an older version internal BEC circuit. Patrick, the president of Castle, was not too happy to find that out, for obvious reasons.”

Posted as above: “UNLEASH THE LAYWERS PATRICK!!! it really does look identical.
My grandfather worked for cinci. Electronics up until the nineties and one of his jobs was to dissassemble rival electronics to see if patents had been infringed,and after looking at this and castles esc he said it looked lawsuit worthy…–Josh”

Apparently, President and Principal Engineer of Castle Creations, Patrick de Castillo also smelt a fish on the design of HobbyKing’s soon-to-be Hot Product. He had this to say:

If it really is a Mamba Monster Clone on the inside… there’s reason for joy, as that’d technically mean that the Trackstar would have closely-similar capabilities at half the price. I don’t think it’s anything like the Tekin RX8 people are comparing it to though, just take a look for yourself….

The only similarities I see is color scheme. Even the cooling fan vents are different. However, those who compare the two aren’t totally without a cause, as the motors included in the respective bundles aren’t that different after all.

The Tekin RX8/T8 System comes at an estimated Street Price of US$349, while the Turnigy Trackstar System (rebranded SkyRC Tor08) comes at only US$127.

For those looking to get one of these ESCs, which are DIRT CHEAP ANYWAY at just US$67, or as a bundle at US$127, my take is, go ahead try it out and let us know, or for the rest… wait for more reviews before proceeding. After exactly 2 weeks, they finally arrived! Hpi Savage X upgrades, and sort of like Pre-Christmas goodies too. In this box I received the:

– HPI 1200mah Receiver Hump Pack
– Robinson Racing Hardened Steel Spur Gear 48T
– Robinson Racing Hardened Steel Clutch Bell 17T
– Robinson Racing Hardened Steel Clutch Bell 18T
– HPI Purple Anodized Titanium Turnbuckles

RB Innovations released a line of superchargers for various popular on-road and off-road RC Cars by a myriad of brands including:

HPI Traxxas OFNA
Associated LOSI XTM Racing
Dragsters Tower Hobbies Tamiya
Sportwerks CEN Racing Serpent
Megatech Hydros Kyosho
Hot Bodies GS Racing Thunder Tiger
Mugen Great Vigor Trinity
Duratrax Schumacher Yokomo

While many RC hobbyists and racers alike have been lapping them up, and even more in response to user reviews posted on popular RC forums like RCUniverse and RCTech, several key questions remain, such as, “How do Nitro Superchargers Work?”, “Will Nitro Superchargers Really Make My RC Car Faster or More Powerful?”, “Will Nitro Superchargers Shorten the Life of My Nitro RC Engine?”, “Are There Alternatives To Nitro Superchargers That Can Make My Nitro RC Car Perform Better?”.

Squirrels RC Forum made two videos to explain this. Do have a look!

Here’s Part 1.

Whoa! A supercharger for RC Car Engine! Can you believe it? Well! It certainly is on my wishlist right now! Gotta put aside money for the baby-expenses first before I splurge more on my hobby.

HPI Savage XL, .25 SS & 4.6 Supercharger

HPI Savage XL, .25 SS & 4.6 Supercharger

The RB Nitro Super-Charger is the ultimate engine upgrade component available in the RC industry. This patented, compact design consists of aluminum and thermoplastic construction. This lightweight construction minimizes engine power required to drive the Super-Charger turbo impeller system. This precision turbo impeller is enclosed in a micro-polished aluminum housing which has been machined from solid billet aircraft aluminum. This provides maximum strength and durability while providing superior air flow from the turbo impeller into the engine’s carburetor. The heart of the Super-Charger’s drive system is a custom composite drive belt that withstands the toughest environments. The Super-Charger’s drive system incorporates a lightweight flywheel, idler pulley system, and a 30% overdrive Super-Charger pulley. The Super-Charger also includes an optional auxiliary pressure output port for boosting fuel pressure to levels not reached by the standard exhaust pump system. This allows maximum nitro and air mixture which boosts engine horsepower. This product was designed and manufactured using one the most state of the art CAD/CAM systems available. All rotating parts within the supercharger are extremely lightweight thus drawing very little power from the engine.

#87230 17mm Hex Hub Conversion Set w/UV Joint (Savage)


These work like a charm! Previously due to a faulty ball bearing, the powerful k4.6 Nitrostar Engine caused a burnout of the left axle. That would NEVER happen with this. It’s so torque-y! If you have a Savage X 4.6, yous should get this! I’ll add a video of mine soon!

HPI Savage X 17mm Hex Hub Conversion Set with Universal Drive Shafts

HPI Racing is proud to offer this new 17mm Hex Hub Conversion Set with Universal Joints for the Savage series of Monster Trucks. 17mm hex hubs decrease the stress on the wheels, helping to prevent stripped wheels when using high horsepower engines. Universal joints deliver improved durability and more efficiency than the stock dogbones. They’re machined from high strength steel, hard chromed for a shiny durable finish that is easy to clean and looks great, and fully rebuildable to add extra life when it comes time for maintenance. These universal joints are factory designed, factory manufactured and team tested for the best fit and durability on the market. To help keep these universals together in the toughest conditions, the joint pin has been made with a special flat spot so the set screw gets a better seat when tightened. Sold as a set of four and includes everything needed to assemble and install. Comes with everything needed to upgrade one truck, including four axles/nuts, a wrench, thread lock and grease

#86187 Ribbed Tuned Pipe (Purple/21+)


Gives my Savage X a nice high-pitched roar! Wasn’t used to the sound! Primes with a different echo as well – almost couldn’t recognise it.  Seems to start easier.
