This is a pair of small parts to lock Kingdom Tracks' outer side leg panels in place in bot mode. I was frustrated by how these panels don't stay in place and move out of position very easily when posing the figure.

The parts install inside of the legs and add a new tab that plugs into the clip on the back of the wheel. They must be removed and set aside when transforming to car mode.

Installation Instructions (see photos):

1. Swivel the leg side panel 90° to reveal the interior of the leg below the knee, and open the gray shin panel slightly.
2. Insert upgrade part into leg, making sure the edge towards the back of the leg is locked under the corner tab on the blue back panel.
3. Close gray shin panel.
4. Swivel leg side panel into its normal position. You may have to pull it out a bit to get it past the tab on the upgrade part.
5. Rotate wheel until the slot in the wheel clip aligns with the tab on the upgrade part.
6. Press the leg side panel into the leg to lock the tab in place.

These look pretty good. Mine really doesn't bother me. Mine did have floppy legs though that I had to fix.

 

Excellent work!

 

Thank you! My copy had really floppy legs too. Once I tightened those up I still had problems posing the figure since the ankles are attached to this panel and it wouldn't stay in place very well.

Here's a look at all of my prototypes. I think it's fun to share these looks at the development process. This one was tricky because of all the angles involved, the limited space to work with and the need for everything to fit tightly.

 

Yeah, this was definitely inevitable.
I have not seen a single review that didn't mention this problem.

 

does it have a place to hang out in vehicle mode?

 

No, I looked at adding that after I got the design functional, but there isn't very much space in the car mode to hide them. The bottom of the car mode is actually very clean. Really the only empty space is at the back of the car around the head, but there's nothing back there for something to easily clip onto, and I couldn't really add anything much extra to the part and have it still work with the legs in bot mode. I tried!

 

I'm excited to announce that I've partnered with @wheeljackfan16 to offer this upgrade kit via the JRC Design store. Both printed parts and STL files are available. Visit https://www.jrcdesignstore.com to check them out!

 

I must have gotten really lucky. All the leg joints on mine are pretty tight. He poses just fine. I thought about making ankles for him to fill out the gaps there, but in the end, it just doesn't bother me enough. What really bothered me was the lack of stripes on his wings.

 

I wish they also played into the transformation, and could also hold the fenders on to the side

 

Same here...Thanks...
