SOME FRIEDRICHSHAFEN "MILESTONES"

"The F.F. 40.
  "This was a very interesting experimental machine, fitted with a 240 h.p. Maybach engine driving two tractor screws placed between the planes (Fig. 20). The performance and general handling of this machine were good, but the transmission was too heavy in proportion to the engine power.
