[Micro IFO] [Micro Kolibri] [Minor] [Trenton Terror] [Kits]
The Kolibri was one of the first all carbon Slow Flyers to hit the scene. It is based on Braun Modell Technik's Stubenfliege. The Stubenfliege is an amazingly constructed plane, it is very light and very well put together, it also costs a lot of money, where as the Kolibri, while not quite as nice can be put together with about US$20-$30 worth of materials.

Scratch built Kolibri.
(There are more images of the Kolibri in the Photo Gallery.)
Construction details:
The Kolibri is constructed of mostly carbon and Reynolds Wrap (or mylar for
the purists). If you have any experience working with carbon you should be
able to put one together pretty quickly. You can get the details of how to
build your own Kolibri at the E-zone site. I made my Kolibri pretty close to the instructions
in the article. I did make one major change, I lengthened the fuselage and
made the v-tails smaller, keeping the tail volume the same.
Here is a close up of the motor mount (made from lite ply) and servo mounts.
Here is a close up of the v-tail horns and push rods.
Flight characteristics:
The Kolibri is a pretty docile creature. The DC1717 with an Anything R/C
ARC-1 prop and a 7-cell 50mAh NiCd battery pack has more then enough power
to haul the Kolibri around. Flight times are around 3-4 minutes, and about
double that if you use an 8-cell 120mAh NiMH pack. The Kolibri is a pretty
stable plane and makes on okay trainer, but since it is such a stable flyer,
do not expect to do any aerobatics.
