DIANA-3 Scale Sailplane Wingspan 4m

= Specification

Wingspan : 4,000mm
Length : 1,430mm
Weight : 2,500 ~ 2,600g(AUW Include battery, after painting)
Wing loading : 33.5g/dm2

This is a Polish-made 18m class sailplane DIANA-3 aircraft with a wingspan of 4m scaled.
It is based on precise scale and modified to have airfoil and wingspan suitable for R/C scale flight.

Despite being a large aircraft with a wingspan of 4m, its READY TO FLIGHT WEIGHT(AUW) is only 2,500 grams.
The wing with an aerodynamic twist is designed with a gently curved leading edge and a trailing edge with Fine winglet.
Also, it has extremely low wing loading of 33.5g/dm2, stable flight is possible not only in thermal soaring but also on slopes.

The carbon pipe spars that intersect inside the fuselage are designed in such way that they not only stiffen the wing, but also
make it easy to connect and disconnect. Actually, only 1 steel pin makes them to be fixed.

It is effective for quickly gaining altitude or slowing down when landing because it has a large area flaps.
Ailerons and Flaps can be combined into program mixing in your transmitter for more effective roll control.(called flapperon)

By combining a motor of about 700~1,000 Watts and a 13~14 inch folding propeller, you can easily gain altitude even in an
environment without slopes or thermals.

A canopy that can be opened and closed easily with a latch system and a large inner space of the fuselage are easy to work with.

Basically, this aircraft is a sailplane, So, it is not suitable for extreme aerobatics or high speed.
You can enjoy a relatively slow but comfortable and elegant flight.

Intuitively shaped parts have been tried to make assembly as easy as possible

The manual contains detailed drawings, part numbers, and assembly order and methods.

Individual part may require cutting, grinding, sanding, drilling.

It consist of a large number of parts and require careful and patient crafting skills.

If you have the confidence to take on a challenge, try it for great results.
