A fully kinetic assessment of the stability properties of toroidal drift modes has been obtained for nanoaxisymmetric geometry, in the electrostatic limit. This calculation is a comprehensive solution of the linearized gyrokinetic equation, using the lowest-order 'ballooning representation' for high toroidal mode number instabilities, with a model collision operator. Results for toroidal drift waves destabilized by temperature gradients and/or trapped particle dynamics are presented. Comparisons of these results with those obtained for typical tokamak cases indicate that the basic trends are similar
