This kit for the EB410 and ET410 from Tekno RC comes with 4 parts:
 
The Battery Spacer. We use a thinner battery and with this spacer we can glue or double side tape a strip of foam to the bottom of our spacer to give nice firm preasure to hold our thin batteries in place (foam not included).
 
Wing Support. We designed this support to have tight pockets that hold the wing mount pads in place to prevent warping of the soft wing mount plastic during an incident that would otherwise twist the plastic permanantly. It can also be used to straighten already bent wing mounts as it does with ours.
 
Wire Loom, top and bottom. We made this wire loom to clean up our motor wires and keep them from getting tangled with other parts of the buggy. Otherwise we would have had to cut and resolder the stock wires. This wire loom has holes in the bottom to mount to the fan location on the carbon fiber plate that is stock on the ET410.  The carbon plate can be used on the EB410 or you can use double sided tape and/or zip ties. The bottom holes accept m2.5 screws and the top uses m3 screws (screws not included). 
 
We have not confirmed if these are compatible with the EB410.2 or ET410.2. If you test these and find out they are or are not compatible please let us know and we will update the listing.
