Delmo (oz14588)

About this Plan

Delmo. Radio control sport delta model. Wingspan 1150 mm. For 3.2 to 10 cc engines.

Quote (google translated from the German): "General information about Delmo: The requirements for an RC Delta all-round model are quickly defined during construction and development:

Small parts count.
Compact structure, insensitive to breakage.
Quick construction.
Wide range of engines possible.
Good flight performance.
Good glide.
Aerobatic.
Can be hand-launched.

These requirements are more than met by the unusual-looking Delmo utility model, which deviates from the usual Delta conception.

The external appearance of Delmo is primarily characterized by the internal combustion engine built in a pull arrangement and the lack of a fuselage. This simplifies the installation of engines with different cubic capacities on the one hand, and on the other hand an extremely simple structure with few components, which in the choice of a special, fully symmetrical profile with a thickness of 10% makes the jig otherwise necessary to build a delta surface unnecessary.

The high mechanical strength of the cell at low weight, which means high susceptibility to breakage due to the occurrence of lower mass forces, is achieved on the one hand by the compact design and on the other hand by the almost exclusive use of balsa wood parts.

Delmo is controlled by two servos built into a mechanical mixer, which control the flaps for aileron and elevator simultaneously; the motor throttle is also operated. The three-channel RC system is protected in the wing root and is accessible from below via a plywood cover .

Unique to a Delta model of this type is the ability to fit engines from 3.2cc to 10cc displacement without having to make a single change to the basic design. Thus it is possible to adapt the flight performance to the skill of the pilot. With a 19 engine, Delmo is exactly the right aerobatic model for the Delta beginner who wants to get used to the flight characteristics and flight characteristics of this model category. Advanced pilots looking for something 'hot' are recommended to install a 40 engine, which represents the right engine for fast flying, unlimited climb and aerobatics, with Delmo showing its particular strength in upward maneuvers. If you like it hot, you can make a whiz out of Delmo by installing a 60 motor .

In versions, the extremely good slow flight characteristics and the stall resistance or spin safety are common, whereby the model remains agile even in slow flight and reacts well to rudder deflections. Due to the front engine, the rudders are always fully blown, which means that Delmo remains controllable at any flight speed. Delmo is easy to launch by hand, it does not require a runway and can be used in almost any terrain.

Thanks to the low wing loading, the model will pleasantly surprise you with its good gliding properties, which greatly facilitates landings with the engine stopped.
