**DISCLAIMER:** **I DON'T accept responsibility for any damage or injury caused by the creation of this design. SPECIAL ATTENTION to the polarity of Li-ion cell batteries! In case of the opposite polarity of batteries, You will destroy the electronics, batteries or burn out! I know what I say :)** ** 2024/03 V1.2 update ** - **Design has been modified to use the digital HD Walknail FPV system. Now it is possible to fly with digital signal specially Walksnail Avatar HD Nano kit V3 with Walksnail Avatar HD Goggles X.** - **change is in the hold of the stick VTX antenna, antenna mount prints using TPU** - **change in battery pin connection - now use cross-section 1.5mm² wire rod** - **some other cosmetic modifications**  Hey FPV drone Pilots! This is the heavy weight redesign of NanoLongRange Evo. It uses a 2S Li-ion battery configuration in serial connection (2pcs of 21700) with 2-4S flight controllers. Flight controller is 25.5mm mount dimensions min 20A continuous current. This Design is compatible with a prop guards from NanoLongRange Evo design. Print parts using PETG material or Fiberlogy Nylon PA12+CF15 recommended by me, it's very firm and lighter material than PETG! VTX antenna strap and antenna-end print using TPU or othe flexi material. Antenna-end part is used against pull out antenna end from the case in crash. The drone is a little heavy but it has a lot of energy and battery capacity. I think he wouldn't be bad for some crazy short flights. **Please take care of the correct batteries polarity !!!** **list of components:** - **2pcs Li-ion batteries** - recommended Samsung INR21700-50S 5000mAh or Molicel INR21700-P42A 4200mAh - Do NOT combine a different type of different capacity or different battery charge state - **battery pin** - use 4pcs from china/aliexpress 18650 battery tray - **flight controller**
