We consider the calculation of n-point multigluon tree amplitudes with a pair of massive fermions in QCD. We give the explicit transformation rules of this kind of massive fermion-pair amplitudes with respect to different reference momenta. Using these rules and onshell BCFW recursion relation, we calculate the analytic results of several n-point multigluon amplitudes.
