This is Kevin with ThrownException.com (Helping you handle the “Exceptional” challenges life throws at you). Today we will be taking a look at a small FPV powerhouse called the GEPRC TinyGo 4k Whoop (https://geprc.com/product/geprc-tinygo-4k-fpv-whoop-rtf/). Starting at $290 for the 1080p version and $320 for the 4k model you can start flying with this amazing package. The package includes an Analog FPV Goggle, Drone and controller. If you were interested in delving into the world of FPVs but were on the fence due to the high costs of a large FPV frame than this tiny full featured 79mm frame may be exactly what you were looking for.

Lets examine the specs. The FPV Goggles are rather are small (314.6g) but they offer an 800×480 resolution across a 4.3″ screen. The Goggles have a built in 2000mAh 3.7v battery and provide 2-2.5 hours of operation. The controller offers a full feature 2.4Ghz unit with a compliment of options to include Angle, Horizon and Acrobat modes. GEPRC has also baked in a function switch for Normal, Buzzer and Turtle mode (Crash Flip) features to address recovery and re-orientation. An additional two-position AUX toggle switch is available for custom configuration. The FPV receiver is an 8 channel 2.4GHz receiver operating on 5v and uses a Frequency Hopping Spread Spectrum (FHSS) protocol.
The FPV operates on two 1S 530mAh 4.35v batteries with a 90C discharge rate and each weighing in at 12.7g. As you would expect the compact nature of the battery affords you 4-6 minutes of flying time making the purchase of multiple set of batteries essential. Finally the inclusion of haptic vibration feedback in the controller makes searching and recovering the miniscule FPV even more convenient.
But the real magic is in the actual FPV. Weighing in at 54.8g and at 79mm motor to motor, this “Tiny” powerhouse rides on the GEP-TG16 frame housing the GEP-12A-F4 controller, the BLHeli_S 12A ESC, the MPU6000 Motion Processing Unit and a STM32F411 Micro Controller Unit. The four GEMFAN 1636 propellers and GR1102 10000Kv Motors make the FPV nimble and responsive. While the package falls in a Bind and Fly category the components offer full configurability via BetaFlight Configurator.
But the real magic is in the actual FPV. Weighing in at 54.8g and at 79mm motor to motor, this “Tiny” powerhouse rides on the GEP-TG16 frame housing the GEP-12A-F4 controller, the BLHeli_S 12A ESC, the MPU6000 Motion POnce connected to BetaFlight, manipulation of modes, on screen dispay (OSD), and virtually every aspect of the software are available. Based on my evaluation the only features unavailable were configuration with BLHeli though motor management operated as expected in BetaFlight. The Video Transmitter is configurable and offers power outputs at 25/100/200/400 and 600. The package comes with either a 1080p Caddx Baby Turtle V2 camera or a Caddx Lorix 4k model, both at 60fps providing both Analog FPV video as well as 4k video to the onboard SD Card video storage.
This concludes our technical review of the GEPRC TinyGo package. Based on our testing and review the overall package for price is exceptional. This compact and rugged package makes it accessible to almost all at a low price. We welcome your feedback and experience on this FPV and leave you with some flight video captured on the TinyGo 4k model.
