	Description	Notes
	Cables LMR400	Pay attention the the length of the cable and to the connector type.
	Batteries	There are several types of batteries and size, you need to make sure that your radio support them or if you need to install an BMS
	LifePO4 Batteries	LefePO4 are best for envirements with extreme negative/positive temperatures. For them you will need an BMS for charging.
	Electrical Box (from Leroy)
	3D Printed STL Batteries Support
	Nylon Breathable Valve Pressure Balance	It’s good to install one breathable valve in your box so huminity can get out.
	Solar Panel	When select a solar panel you should take in mind the way to connect them some radios support direct connection (with limitation on the watt’s and voltage) others you will need the BMS
	BMS for LifePO4 Batteries
	18650 Batteries Supports
	Type-C Bayonet FPC female Male Back
	MikroTik 868 Omni	Mikrotik 868 Mhz 6.5 dbi
	Alfa AOA-868-5ACM	AOA-868-5ACM – EU LoRa 868 MHz Antenna 5dBi N-Male.
	RAK 19007 / RAK 4631	Select CN-Europe to prevent problems with the customs when ordering from Europe. Also make sure you select the right radio and base.
	SMA to IPX Pigtail	Pay attention the the length of the cable and to the connector type
	UFL MHF1 to IPX Pigtail	Pay attention the the length of the cable and to the connector type

MITRA FPV Amphibious traked vehicle (5)

That is the current state of this project

Here we can see how i attach the parts to the cnc table , is a 20mm phenolic board. I start to drill 2,5mm holes that belong to the parts then i drill 2mm holes in to the phenolic to screw the wood bolts, that way after cut the perimeter of parts they stay attached to de table.

All the parts machined till now…

Hi, finally the frame is completed . Some tweaks on the bearing outside support have to be made, to do it i made a plastic jig and machine one at a time… it works fine.

With the small parts i did almost the same but by option.. i rough cut them then i trim the outside on the jig this time three at a time

Some updates on the build

After some break downs on the cnc hardware, air compressor, wireless keyboard and the air oil assist “mist”. Finally had time to give a big improvement on the production and trimming of the larger pieces.

First machined parts

Some luck.. the bearing fits at the first try

It is a long time since the local track as closed and because of that also my Rc activity.
In the mean time had been drawing a new FPV vehicle capable of running while rains and even capable of crossing puddles.
Early had experience a long runs on foot to get my previous vehicle when he overturned, with this design no need for that because run both sides.
The electronics are housed inside aluminium tubes and only the antennas are out of it.
The project not yet finished still remains draw the dome for the camera.
