With more & mora demand of aerial survey UAV, the problem of needing a suitable data transmission is growing. Our company has been engaged in aerial survey operations for a long time, & has been surching for asuitable data transmission radio. However, the cheap stuff on the market are unstable & unreliable. So we tested all the radios on the market, & the result of countless flight test led us to this module. Stable performance, affordable price & compatable to PIX APM flight control.
