Build Log


Ulti-X, the bigger sister of the crack turbo beaver.

Inspired by the 45 x-fuse design of the crack turbo beaver, I designed this KF-stepped X-fuse Ultimate.
It has 100cm wingspan and is well balanced with a 2200 mAh 3S Lipo.
Motor Roxxy 3530 / 1330kv.
Flyingweight is about 720g. The Ulti-X is very easy to fly and a perfect 3D-trainer without any critical behavior.

It is made out of Depron, mostly 6mm and a bit EPP and plywood.

Ulti X, X-Fuse Biplane (1 min 44 sec)

greetings Stefan

Let me provide a few build pictures.

Maybe someone likes to try a build and we can see more ulti-x flying around.
