Topo III is the last Topo produced. It is a 2 piece body, Seamed on the sides and has a handy tray to replace the folding arms. It uses the same electronics as Topo II. The metal chassis is improved and much lighter. The number sold is unknown, but the best guess is less than 100. Topo III has a design defect, as the neck is very thin, and most have had the head broken off! Also, the price increased, almost triple of the Topo I.
