Price
Eachine Tyro79S RTF is available for purchase on various Internet marketplaces. The developer has set the following prices depending on the configuration:
- 2 Battery Version - 165 $
- 4 Battery Version - 178 $
Conclusion
Without exaggeration, this is one of the best outdoor RTF kits for quickly entering the racing drone niche. An excellently tuned quadric with exponential dynamics, with support for 4S power supply, which is good news. Easily copes with the additionally installed camera GoPro 7.
The disadvantages include the stock FPV camera (recommended as a replacement: Foxeer Predator Micro V3 / V4 or analogs), stock props (recommended as a replacement: 3-blade Gemfan Windancer 3028) and stock power (recommended replacement batteries: CNHL MiniStar 650mAh 14.8V 4S 70C Lipo with XT30 connector; CNHL MiniStar 650mAh 11.1V 3S 70C Lipo with XT30 connector).
