Sunbird Electric Glider Laser Cut Balsa Kit 1600mm (Kit)
Here's another of our superb Laser Cut Balsa Kits for the traditional R/C hobbyist and builder who enjoys constructing models from kit form.
The Sunbird is an all built up 1600mm, 4 channel, electric powered glider - with a little 'old timer' flavour mixed in!
the Kit features sharp accurate laser cut parts that simply slot together with little fuss and the wing looks fantastic when covered with transparent covering to show of the construction and your handywork.
The power system can be a simple small outrunner and 2s battery, using micro servos to keep her nice and light.
The resulting model is a great little park fly electric glider that performs well and has aileron/elevator/rudder/motor control. The Sunbird is tough enough to handle the odd 'oops!' moment from novice flyers and compact enough to be transported easily.
Specs: Span: 1600mm Length: 850mm
Requires: 4 Channel radio system and 4 x micro servos 1550kv 15amp Outrunner 15Amp Esc 2 or 3s 1300mah Lipo battery Propeller (8 x 4) CA glue Covering film Basic hobby tools (knife, sand paper etc)
Build manual is listed under the 'Files' tab below
Depends if you want a spinner bigger than the fus!!
The fuselage is 42mm wide at the main wings tapering to 36mm at the nose. It is however greater than 36mm high at the nose. I elected to add some 4mm balsa to the inside bottom of the nose and 10mm triangular corners so I could use a 35mm spinner, nicely rounded nose to fit, and folding 8 x 4.5 prop.
Also note the nose is quite long so I put the rudder and elevator servos side by side as far back under the main wing so I have the option to have the battery well back. Not flown yet (but nearly there) The KEDA A22-10s motor should get it skyward pretty quickly with 3 1500mah bat! Mike
Nice video, and a lot of work.
On the building manual the leading edge of the wing is more or less a straight line viewed from above, but yours has angles, why? The rudder is higher than it should be, why did you build it like that?
It seems more complicated than it should be to me.
It is always a lot of work to build this model. The leading edge of the wing has an angle in the mimiddle and 4 more angles atb the beginning of the outer section of the wing. My sunbird and other sunbirds have tjhis angles of the wing. A wing with ailerons usually has small angles for flying it. Without angle you can fly faster rolls.Flying rolls with the sunbibird is not quite easy.
Not a kit for the beginner!
Its not terribly difficult to put together but I wouldn't recommend this kit to someone who has not built a couple of other airplanes.
I am still awaiting delivery of the sunbird, but you guys can't seem to agree on much some say great others infer a load of rubbish. Does HK not take notice of all the comments you guys make about their shortcomings or is it a language thing!!
The Sunbird is the second plain I made. It was realy a pleasure to find out how to realise it, as the instructions are "not allways clear". I uploaded 14 pictures, so I hope that everybody can see my black/red Sunbird result soon.

Since the accuracy of the laser cut was bad, difficulties were required for building a plane. However, flight performance is wonderful. Easy circling, easy flight control.
It was a disappointment in the good meaning.

my setup C20/1400mah 3s/6x4 folding prop.
build was straight forward but the instructions terrible... followed the "half a guide" in the file section which was handy :)
parts all fitted well compared to the old balsa kits I used to build 25 years ago..
quite a twitchy thing to fly I thought. glides magic though. cant wait to try it sloping..
enjoyed building this.
