NEWS: IDEAFLY IF88, a compact 88mm F4 based micro brushless FPV racer

Drone News · April 28, 2017

A new compact (88mm) microbrushless racer is introduced by Ideafly, the IF88: http://www.gearbest.com/brushless-fpv-racer/pp_626283.html. It’s probably one of the first integrating a Flight Controller board with an F4 processor… so even faster PID loop time (16Khz…) will be allowed. More a builtin OSD is also included, betaflight driven. Actually only a FrSky receiver solution is offered but with a XM microreceiver need to be bound in D16 mode. More channels are offered as well as better control range. No real information about the ESC are given except they are officially only supporting 2S LiPo with 3A (max at 7A).. no real hope to see them working at 3S … Hope they are at least BLheli_S compatible. For motors, classic 1104/7500Kv. The FPV rig is a 25mW 40CH CMOS NTSC 600TVL AIO camera. The flight controller seems to be super exposed … to crash and to water. Whithout dedicaced canopy, the design is ultra simplist and a bit ugly IMHO. The total weight incuding the battery is relatively light (77.5g).

Main Features:
– High-performance F4 FC with STM32F405 MCU, BMP280, MPU6000 and micro SD card slot for flight data logging
– FrSky XM 2.4GHz 16-channel receiver intended for more fun in FPV racing and more than 600m long control range
– Small and durable – 88mm wheelbase, true “X” configuration, 2mm thick 3K carbon fiber chassis
– Powerful 1104 7500KV high RPM brushless motors and 2030 three-blade propellers for thrilling flight
– 5.8G 40CH 25mW image transmission + 600TVL NTSC camera featuring good image quality in strong / low light and 120-degree FOV
