Abstract
We estimated values of spin, mass and inclination angle for sample of 42 red quasars. Our estimations show that 2 objects: F2MS~J1113+1244 and F2MS~J1434+0935 with highest Eddington ratios may have geometrically thick disk. Six objects: SDSS~J0036-0113, S82X~0040+0058, S82X~0118+0018, S82X~0303-0115, FBQS~J1227+3214, S82X~2328-0028 may have "retrograde" rotation. Analysis of estimated spin values shows that red quasar population may contain Seyfert galaxies and NLS1.
