Vortex 4 1.5m DLG

The ground breaking DS Composites Vortex 4 four servo wing DLG is prbably the most highly regarded DLG currently available. The extra controllability of the separate flap and aileron control surfaces gives greater manoeuvrability with less control surface drag in thermal turns and normal flight modes. However the ability to have crow braking on landing greatly improves control on approach and landing, reducing the likelihood of fumbled catches and resultant damage. Plus the thoroughbred low drag design of the Vortex 4 and excellent surface finish give high launches and an excellent glide angle.

Like the Vortex 3 the build quality is excellent and the engineering is very impressive. Apart from of course perfectly molded carbon parts the kit comes with a very nicely engineered system for automatic connection of the aileron controls when the wing is attached. This is a different level of convenience and functionality to other DLGs we sell.

Supplied with a complete accessory bag including all the items necessary to complete the model. Two servo trays are included, for KST X08 and MKS DS65K servos.

The MKS servo tray cutout is 22mm x 17mm, making it suitable for 4 DS65K servos. To fit 4 DS75K servos in the MKS tray 0.5 mm needs to be trimmed from each edge of both cutouts.

The KST servo tray cutout is 23.5mm x 16mm, making it suitable for 4 X08 servos or A08 servos. The cutouts are too large for the X06.

Note, the top mounting surface on both trays is flat, so servo installation may require thin spacers to raise the 2 front servos so that the tail strings clear the aileron pushrods.

We are stocking the two piece wing version (2pw) with a bottom mounted tailplane, in various layups.
