The Warren CP-1, also called Miss Poly, Miss Polytechnic and the Warren Monoplane, was the second aircraft built by engineering students at California Polytechnic College. It was a high-wing monoplane with a 135 hp Comet 7D radial engine.
Recognition (WEFT)
| W — Wings | High-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | Fabric-covered welded steel tube fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- High wing with dual airfoil-shaped lift struts
- Fabric-covered welded steel tube fuselage
- Exhaust collector ring around the radial engine
A high-wing monoplane with conventional landing gear, dual airfoil-shaped lift struts and a red, yellow and blue paint scheme.

History
The CP-1 was built for Cal Poly instructor Martin C. Martinsen and completed in August 1929. It was licensed as an experimental aircraft and test flown from E.W. Clark Field in September 1929.
Variants
Only one CP-1 was built. An exhaust collector ring, a larger rudder and low-pressure wheels and tyres were added after construction.
Where you'll see it
It won a silver cup and two blue ribbons at the California State Fair, and on 29 June 1930 reached 18,200 ft to win a record for student-built aircraft. It was sold back to Cal Poly in 1932 for aerial photographic survey work, and its licence expired in 1934.
