Good, easy to build kit. The instructions are in Chinese, but that doesn't matter. Quality is very good. The tail and elevator are a little weak, but I have not broken them yet. The rudder is inadequate. Make a new one with a little more surface area.
The carbon tube for the back of the fuse is tapered - very nice touch that gives good strength and stability.
The wing also seemed a little weak, but is actually surprisingly strong. Finished weight with a 350mah battery and ailerons is 196g.
IMPORTANT - When building the wing, use the formers that come with the kit to shape the bottom surface of the wing.
I flown this glider for about 2 months now, and love it as a slope soarer. It has better handling and penetration than the guppy, and when fitted with ailerons becomes quite acrobatic.
This glider is able to fly on the lift created by a long 3m high dune in about 4-6m/s wind and get enough energy up after 3-4 passes to do some acrobatics
For ailerons/flaperons: Cut the trailing edge pice just behind the wing ribs. Glue in a flat piece of carbon and re-attach the trailing edge with hinges or tape. There is enough room just behind the main spar for a micro-servo in each wing. This makes a thin aileron that works well, but is limited as flaperons.
, 1:1 700 1000,High quality kit. The parts fit and are perfectly cut.
There is lots of scrap for modifications, reinforcing etc.
The instructions are a Little unclear, so dry-fit all parts.
There is plenty of room in the fuselage to move receiver and batteries, so balancing is easy. The wing is strong, with two carbon strips at the top and bottom of the spar.
The trailing edge can be cut to make ailerons. There is enough room in the wing for a micro servo in each wing giving it the ability to have flaperons.
Performance is fair for DLG due to the aircraft being a Little bit heavy, but this just adds speed when slope soaring.This looks to be much higher quality than the other HK balsa kits. The parts are all numbered, and there is are full size layout plans in the box. The laser cutting looks good, and the hardware is also included.
