Spot it by:
- Cantilever low-wing monoplane with constant-chord wings and rounded tips
- Tandem open cockpits, the front just ahead of the wing leading edge
- Exposed-cylinder radial engine and a fixed undercarriage on tall faired legs with a tailskid
A low-wing monoplane with a conventional tail and a round fuselage section, with two open cockpits in tandem.

History
J.W.H. Lambach designed it to be cheap to produce and operate, and about twenty-five students built it from the spring of 1934. It first flew on 5 July 1935, piloted by Dick Asjes.
Variants
It first used a 45 hp Szekely SR-3 radial engine, which proved unreliable and was replaced by a 90 hp Pobjoy Niagara. Only one was built.
Where you'll see it
It was registered as PH-DSA on 1 January 1936 and served at the National Flying School at Ypenburg until the German invasion in May 1940. It was later dismantled at the Technical University of Delft.
