Product Code: BLASTER-3
Description
Blaster 3 DLG
The Blaster 3 is the long-awaited successor to the award winning Blaster line of 1.5m DLGs from Vladimir's Models. The Blaster 3 is a great improvement in DLG design, building upon the experience gained in development and manufacturing of the first two Blaster versions. It meets all the requirements for a competition level discus launch glider, while being suitable for intermediate and even less experienced pilots.
This "Light" version has a glass and Rohacell wing skin, with a substantial carbon spar. It is fine for most fliers, but we recommend modellers who launch hard to get the stronger spread tow layup.
Blaster 3 is designed in CAD from the ground up. It combines unique design, the latest composite materials, the state of the art manufacturing process and careful manual composite layup. Blaster 3's visible simplicity hides its structural sophistication.
Thanks to the advanced aerodynamic design by Dr. Drela and extremely streamlined fuselage, we have developed a uniquely controllable, fast, light, and strong glider with excellent penetration ability.
The Blaster 3 has these major improvements over the Blaster 2:
The Blaster 3, unlike previous versions, can have the launch blade attached to either wing, allowing the model to be build for left handed and right handed throwers.
The wing design uses state of the art hollow molded fabrication techniques to maximise strength, while keeping weight to a minimum.
The spar is constructed from high modulus unidirectional carbon flanges, which are bonded to the wing skin, these are kept rigid by the web, which is made from high density blue foam strengthened with a braided carbon fibre sleeve. This ensures +/- 45 degree fibre orientation, ideal for a shear web.
The wing skins are made of Rohacell foam and glass cloth. The ailerons are very light and stiff due to a braided CF sleeve spar.This also moves the aileron CG forward, preventing flutter during launch.
For build and flying info see this excellent RCGroups Blaster 3 build log.
*The Hyperion DS09-SCD are excellent, but are a tight fit in the fuselage,
so the installation needs planning carefully.

The Blaster 3 has these major improvements over the Blaster 2:
- Lighter, from 260 g flying weight, approx 40 g lighter than the Blaster 2.
- Easier and quicker to build.
- Smaller fuselage with smaller pylon reduces drag.
- Shorter tailboom and smaller tailplane reduces inertia and improves manoeverability.
- Stiffer wing mount and tail boom increases the launch height.
- The above result in a model that launches higher, has improved hang time, and thermals better.
