In this video, I spend some time Rock Crawling at the Creek with my HG P407 (Tamiya Bruiser Clone / 타미야 브루져 카피).

My HG P407 is in the process of going through a transformation. Some of the changes are modified to accept 12mm Hex so that I can use 1.9" beadlock wheels, removed chunky electronics box, and battery and electronics are relocated.

Upgrades & Modifications LIst
Must Do:
#1 Front Steering Servo Mod - relocate the steering servo to front and upgrade to high torque servo with metal 25T horn. You can download the 3d file from Files section, or order Ampro’s from Shapeways. Few cheap, but effective servo options:
#2 Replace the stock bearings. Options as to where to purchase the bearing kits:
#3 If you plan to take it offroad, you will need to lock the front and rear differential with pins included. There is a small hole that you can install the locking pin, but there is actually 2 different sides on the transmission, one side is threaded and the other side isn’t. I recommend opening the axles (especially when you are opening it up to replace the bearings) to ensure that you are installing it from the correct side and tightening it down accordingly.
#4 Replace the stock tires with better compound. Most folks run with Proline Hyrax copy, Austar AX-3021. Cheap and works great (not as long lasting as original Hyrax though) - https://amzn.to/2xdnmN1 | https://ebay.to/2VBoGla
Optional Upgrades & Modifications:
  • Battery relocation and removal of Electronics box. This isn't for everyone, but my experience has shown that it makes a huge difference in climbing capabilities. Much more involved as you have to fab the battery holding plate, and electronics tray.
  • Upgrade the ESC - will give you much more refined control. Most folks recommend Hobbywing 1080 ESC as one of the better choices - https://amzn.to/2POhgct | https://ebay.to/2wISYtT
  • Buy bigger and better 2S Lipo battery (make sure to buy decent quality battery. People have been happy with Flureon brand). Personally I like Gens Ace/Tattu brands. Here are some options:
  • Gens Ace 7.4V 3500mAh 2S 60C Shorty LCG - https://ebay.to/3esYLEO
  • Gens Ace 7.4V 3500mAh 2S 60C Shorty LCG (2 Pack) - https://ebay.to/3esYMsm
  • Gens Ace 7.4V 4600mAh 2S 60C Shorty - https://ebay.to/2wMI86i
  • Floureon 2S 5200mAH Lipo RC Battery (2 pack) - https://amzn.to/2vGnNyL
  • Leaf Sprung Mods:
  • (FREE) Remove 1 leaf springs - front and back. Most folks recommend removing the smallest leaf from each corner. I ended up removing the middle leaf.
  • Remove springs on shocks and add washers. Stock shocks are not very good and they leak. You can make modification to improve it. A good video from Dennis Dempsey Radio out of Control - https://www.youtube.com/watch?v=Iin6AAnf4gI
  • (FREE) (rear only) turn rear shackle mounts around. It lets the back flex a little more than current setup, and lessens the chance of snapping the leaf springs as it will have enough compression to not over work the leafs.
  • (FREE) chino mod
  • (FREE) break in those leafs
  • Install LED lights. I am using the following light kit. Ampro Engineering did reviews on few different sets, and this one was recommended. The only downside is that for the brake light, you will need to solder in 3mm red LEDs instead of the 5mm red LEDs that comes with it - LED Light Kit - https://ebay.to/34EyqPP
  • Replace transmitter & receiver with Fly Sky FS-GT3B, hack firmware (key benefit is ability to convert it into 6 channel system) and mod to Lipo battery. Not necessary, but it is so nice have an upgraded transmitter. If you do go this route, here’s a video that I put together to mod it to use Lipo battery - https://youtu.be/pYCW6VbDgMo
  • 12mm Hex Conversion. Best way is to either get the RC4WD 12mm hex conversion kit or replace the axles to Yota 1 or 2 axles (it's easy conversion on front, but for rear you will need to look for Bruiseraptor axle which is discontinued and difficult to find). Additionally there are 3D printed mod options, but they tend to stick out the wheels too much.

Here are list of tools that I use to work on my RC trucks:
 

Here's how to bind a new FlySky FS-R6B receiver with my FlySky FS-GT3B transmitter radio. Hope you find the information useful.

In this video, I modify a new FlySky FS-GT3B transmitter to use 3S LiPo in place of 8 AA batteries for extended run times while making it a bit lighter in few simple steps. Hope you find the information useful.

So here are 3 essential 3D Printed Mods that makes FlySky FS-GT3B even better. The files are hosted in Thingiverse and are free for download.

Here is a short video of HG P407 (Tamiya Bruiser Clone) out on a local creek trail. It's a RTR Black version that has few modifications that turned it into a decent trail truck that can handle some crawling abilities.
