Tiny Tank FPV (18650 Li-ion version)

###FPV Tiny Tank using a 18650 Li-ion cell # This is a FPV RC tiny tank designed with an idea of having a small form factor while providing longer driving times than other similar tanks using a LiPo battery. The 18650 Li-ion cell has a high energy density, which gives an opportunity to undertake "long range" missions with the tank. Personal experience shows that a 3200 mah cell let's you easily drive this for more than an hour. The tank also has controllable front LED lights. **Wiring diagram included** (attached as an image). --- #Used parts list# (shorturls lead you to aliexpress for cheap options) ####Electronics:# + FrSky Xm+ receiver (it's possible to use other SBUS receivers) https://shorturl.at/qHV05 + SBUS to PWM servo decoder https://shorturl.at/hN025 + 2x 9g SG90 servo motors https://shorturl.at/crCE4 + PWM signal control switch (controlling front LED lights) https://shorturl.at/enHIX + Eachine TX04 3 in 1 video system https://shorturl.at/pGM78 + 2x 5mm LEDs + 50 ohm 1/4 watt resistor + 18650 Li-ion cell ####Hardware:# + 2x M3x20mm screw (for passive wheels) + 2x M2x6mm screw (for drive wheels) + 4x M3x15mm screw (for connecting base and top chassis) + 6x M3 4.2mm diameter heat insert nuts (2 for passive wheels and 4 for chassis connection) https://shorturl.at/cjC56 + Battery connectors (possible to salvage from old battery trays or be creative; see photos) + 2x 6x19x6mm bearings (for passive wheels) https://shorturl.at/mIO13 + 4x 4x2mm magnets (for battery cover) https://shorturl.at/bgotW --- **Notes:** + Servo motors need to be modified for 360 degree rotation (there are plenty of tutorials on youtube) + Top chassis and battery cover are connected with a single 1.75mm filament piece + Every part except the tracks is printed with regular PLA.
