We explore two types of mechanisms during particle precipitation into flaring atmospheres which can cause particle anisotropy: self-induced electric field combined with collisions versus magnetic mirroring in strongly converging magnetic field by using time-dependent Fokker-Plank equation with pitch-angle diffusion. . The anisotropy of precipitating particles is shown to be the key factor in observation of hard X-ray and radio emission owing to the scattering directivity for emitted photons meaning that pure collisional models cannot reproduce the emission observed from the atmosphere top.The resulting hard X-ray and radio emission and directivity are calculated for each model distributions for different times and various depths and compared with those observed in a few solar flares located at different parts of the solar disk. We show that a combination of viewing angle and particle anisotropy strongly affects the observed emission.
