Description
Blaster 2 DLG F3K
Two-piece wing DLG for right handed throwers.
The Blaster 2 is a high tech F3K r/c hand launched glider utilising airfoils designed specially for DLGs by Mark Drela. To help with storage and transportation this updated Blaster 2 has a wing that splits into two parts – this is cleverly implemented and only adds 6g to the model's weight. The break is asymmetrical, and the wing that is used for launching is fully bolted to the fuselage, so the wing join only has to take the forces on the outside wing. This facility also makes the Blaster 2 into a brilliant holiday glider, that can be flown from the beach, small dunes, or any small field.
The hollow-molded wing is made in CNC machined molds to ensure the airfoils are reproduced accurately, and the potential performance is fully achieved. The elliptical planform and transitioning airfoils give the wing a very high efficiency, together with excellent handling characteristic and a benign stall.
The superbly finished wing comes complete with a moulded-in aerodynamic winglet on the left wing only, for tip launching by right-handers. The wing also has pre-cut servo mounts and bottom hinged generously sized flaperons, to allow the model to be slowed down to a crawl for hand catching. This high level of prefabrication makes the glider especially strong, clean, and easy to build.
The wing skin is a very rigid and tough glass/rohacel/glass sandwich with a substantial carbon spar.
The glass skin is laid at 45 degrees to eliminate twisting and maximise launch height. The carbon braid reinforced shear web is bonded to the substantial carbon spar caps, resulting in a light but strong spar.
The living skin hinged flaperons have a rohacel core and a very sharp trailing edge to minimise drag.
The spacious pod is Kevlar reinforced with a horizontal strip of carbon fibre extending back to the boom, and is covered by removable nose cone to keep the front end clean and maintain laminar flow. The pod includes a wing mounting pylon to reduce interference drag, and fairs smoothly into the generously sized and very stiff carbon tailboom.
A lightweight v-mount keeps the full flying tailplane out of the disturbed airflow, and gives the pilot excellent low drag pitch control.
Download our Blaster 2 Assembly Guide to see how easily and quickly the Blaster 2 goes together. Our thanks to Martin Bell for his help with the manual, and for permission to use his excellent photos.
Do look at this New Blaster 2 RCGroups build thread which shows how to fit all the servos in the pod, as now recommended by Vadimir's Models.
The Blaster 2 is supplied with a throwing blade molded into one wing side only. The normal version has a two piece wing, and has the blade on the left side, making it suitable for right handed throwers. The left-handed version has a one piece wing with the blade on the right side. They aren't easily changeable - you have to buy the right one!
