HPI SAVAGE Nitro to “Flux HP” Conversion

HPI used to sell a kit called “#102534 – SAVAGE FLUX CONVERSION KIT FOR NITRO SAVAGE”. It’s discountinued but we can still find all pieces in that kit on rc4me.us. (And here is our kit with Center Differential & Slipper Clutch Eliminator Spur Gear.)

Let’s start making a list of all these parts (and see how much it would cost):

  • Flux TVPs: The TVP Chassis for Savage Flux HP are different from the ones on the nitro Savages, simply because you need to fit motor and esc in between the two plates.

  • Motor Plate: This plate is different from the nitro engine plate. It’s actually stretched out of the right side plate to provide space for the brushless motor.

  • Motor Mount Brace: These two piece of metal braces are mounted parallel to the TVPs, which is not the same as the ones on nitro Savages.

Besides the Metal Spur Gear and Pinion Motor Gear, the above list is about everything you can see between the left and right TVPs.


Sure, you need motor and battery. But what else?

The 29T Metal Diff Sets and the 9T Bevel Gears are recommended to serious basher but are not essential for the conversion.

But wait, the center gear box for nitro savage is a 2-speed or 3-speed transmission, and can only spin forward – we’d not use that. We recommend to use a Center Differential Transmission, however, you have a cheaper and yet easy option: Use a Idler Gear Set to convert your nitro gearbox into a single speed gear box for electric motor. On the Idler Gear Set page, there is a video showing how to change the gears.

Congratulations! That’s about it for the HPI Savage electric conversion!

Oops, wait, I’ve thrown away the fuel tank but where should I put the Lipo batteries?!

Let’s get this Battery Box Set. It comes with screws and all you need is just bolt those onto the TVPs.

In the HPI Savage Conversion Kit (#102534), a ESC mount is not included. You can get it Here.

If you like the Heavy Duty Dogbones and Diff Shafts included in the HPI Savage Electric Conversion Kit, we also have them on our site.

We will talk about upgrade your brand new Savage Flux with CVDs and Aluminum Parts later.

Thanks for reading. Let us know your thoughts by leaving message.

P.S. Screws!

Since you are converting your nitro Savage, you already have the screws for the TVPs and the Motor Plates/Braces. Now you need these M4x8 screws to mount the motor clamps onto the plate, and then these M4x30mm screws with spacers to fix the motor.

Now, Choose your Brushless Motor for this 1/8 Monster Truck, and Pinion Gear.
