I am coming for sure. 

Wow, amazing!  It would be nice to see it at some small RC car in real action.

Kontronik has 5.6v output by default (that's what I use). It is safe for BLS251 for sure. But it looks like even at 6v it is safe too. Most of the pilots I know use BLS251 at 6v with no issues. BLS in general are not as sensitive to input voltage as brushed servos.

When you build Logo 400 SE pay attention to forward tail gear mesh, and tail blades balancing. Balance them dynamically (installed on tail rotor). Unbalanced tail blades/rotor makes loud humming noise. Almost every set of tail blades which I have tried on Logo 400 required balancing (Radix, Edge, stock plastic).

HV80 should work fine for you. Kontronik do not mind to run low throttle.

You can run it stock on SE even if you use 105mm. Just do not go over 1800 head speed (officially recommended maximum head speed). If you want to go higher it is better to upgrade the tail.

I have for sale Kontronik Jive 60LV V9 with Heatsink. I ask 150$, retail is around 250$ with heatsink. It is ideal speedcontroller for Logo 400, Trex 500 and Protos. I have stretched my Logo 400 to bigger blades and need 80LV now.

What helicopter and motor you are planing to use with that ESC?
On 550mm blades with 4025 motor - this ESC will work for mild 3D.
On 600mm with 4035 motor - it will be good for hovering only.

Looks good! But next time I want to see  nose of the heli too  .

Hi Guys,

Elk Point fun fly takes place this weekend (July 1-3). Awesome event, awesome field, open for helis and planes.
I am (and few other pilots I know) going there for sure.

Just a reminder that SHAG is coming. Who is going?

Hi Guys,

I have converted my Logos to 12S setup and I have few used 5S 4400ma-5000ma packs left. You still will be label to get few cycles out of them. Let me know if you need them.

Cool! Thanks for taking the pictures/video.

The heli is HUGE!

Raymond, Nitro will save you money only if you fly very rare. In long run electric helis are much cheaper to run (even 700 electics), less maintenance, motors last almost forever (you have to rebuild or buy new nitro engines quite often), and they are way more powerful.
But some people like Nitro smell and loud noise
