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
.110" carbon rod fits the notches in the ribs pretty well. In my opinion it makes the leading edge look very nice and provides better structure than using the balsa sticks that are in the kit. Plus it is less shaping you'll need to do to get a good airfoil.
I used the original leading edge and I didn't shape it at all…* it is strong enough, but I reinforced the wing with extra 'web' between each rib, 2mm extra balsa on each side, that made the wing much stronger, and only a few grams more in weight.
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!!

I dont recommend this kit for the main reason that half the pieces were not cut through. The advertisement stating "sharp laser cut parts" is completely misleading. I normally dont mind cutting out balsa when I build from a plan but not when I have bought a kit for a quick build that states "simply slot together with little fuss". If I dont bin the lot then I will have to cut most of the parts out by hand and its not soft balsa. The second and minor reason I dont recommend this kit is that there is no plan to help line up all the angles. The well printed colour build photos are very useful but inadequate.
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.
