The Mechanics

Jan 27, 2025

I started the assembly few months a go and unfortunately I have to say that the Roban manual needs a huge improvements to match the product that they sell. Most of the pictures are so small and don't have any details regarding the screws that needs to be used. I found it some how difficult, however thanks to the internet I was able to find many pictures from other builder that help me on this journey.

Even if I initially purchased a 3X Demon, I decided to switch to an Ikon2.
I 3D print a bigger tail fin, since with the 600 size I have, I was afraid that the tail blades were going to hit the ground.

First Flight

Just testing that everything moves in the right direction, before taking everything apart and start the fuselage assembly.

Fuselage

Jan 29, 2025

Overall the Roban Fuselage is very nice. Almost everything that came with the Kit fit without too many alterations.
I spent sometimes trying to find the best fit for all the components, ESC, Battery, etc..
I decided also to keep some of the scale accessories removable in case I need to do some maintenance to lights, etc..
The manual is not helping too much... 😞

Lights

Feb 3, 2025

I’m not very happy with the light system that came with the kit. There are no instructions, and the lights pattern doesn’t look right to me for this helicopter. So, I build my own system, not just for the outside but also for the inside.
I also added a switch to the console, so i can decide when keep on or not.

First hover

Feb 5, 2025

I finished with few details, checking CG and testing that all works fine.
I think I'm "happy", so far, but I see a little tail wag and I hear little noise that I need to check out.

Tune up time

Aug 9, 2025

Ikon2 experts help required...... Yes, I'd like to ask the Ikon2 experts what method are they using, in scale models, to adjust their Ikon2 flight controller and how they adjust the mid stick to a 4-5 degrees angle. May be there is a video somewhere that explain that but everything I found so far are setup for 3D helicopters and so the mid stick pitch is at 0. The Bavarian 3X have a nice option but I can't find anything similar for the Ikon2. Any help is appreciated.

Thanks to all.
