Build Log

Marabu II.


Hi all!

After very sucessfull model Marabu (1) I build couple of years ago, and many friends asking me for a CNC version of this particular plane, I decided to redesign Marabu model to be "friendly" with CNC technology and "puzzle" alike assembly, to allow easy and fast model building.

Model is of 2,65m wingspan and its flying weight is well under 4 kg, so it is a really slowflyer.


SHORT KIT available here: http://ultralajt.webs.com/apps/webst...s/show/6047942

DXF files of all parts suitable for making them on CNC machines available here: http://ultralajt.webs.com/apps/webst...s/show/6649574

Some photos of the assembled model:

This prototype is equipped with relative weak motor, so steep climbouts are not achieved. Motor is about 700W while at about 1000-1200W it can do "jumpstarts".

This is a video of maiden flight:
