We compute the symplectic reductions for the action of Sp2n on several copies of C2n and for all coregular representations of Sl2. If it exists we give at least one symplectic resolution for each example. In the case Sl2 acting on sl2+C2 we obtain an explicit description of Fu's and Namikawa's example of two non-equivalent symplectic resolutions connected by a Mukai flop.
