The Goblin 770 Competition is the biggest of all Goblins. As I am a known fan of the 800 size I knew that I would aim to have a big "Flap Flap" machine again. And because I really love the Carbon edition of SAB I decided to get the Red/Carbon 770 :)
The 770C is just amazing! For me this machine represents heli-ingeneering in perfection! The heli looks like a "Air-ferrari" racing machine. And without canopy
you will be stunned by all the fine carbon and aluminum shiny parts. All devices and components have their proper place, everything looks tiday and well planned. The cables can be wired securely,
clean and hidden, thanks to so many advices and suggestions in the manual. So at the end you will have a real eye-catching machine, with or without canopy.
Because I didnt have to care about the weight when I built the 770, I chose a real fat power setup for it. The Motor is a Kontronik Pyro 800-48, which doesn not only look
monstrously powerful but indeed its one of the best motors on the market. The counterbearing, which is included in the kit, fits only to 6mm shafts. As the Pyro has a 8mm shaft I
chose the "short" version of it. So there was no need to shorten the shaft and I have plenty of room under the motor pinion and can use big batteries.
The ESC is a Kontronik Kosmik 200 HV, which is the most impressive and maybe best ESC on the market. It has a integrated logging on SD-card, a HV BEC and a
governor which is so awesome that it was never reached by another ESC. It is suitable up to 14s, I run it with 12s. It is mounted directly under the battery in the front, where the heli already
offers some predrilled holes to install it. Combined with the Kontronik TelMe I can directly read on my transmitter my current Ampere, voltage, used capacity and
A big heli also needs big powerful servos! On the swashplate I use Graupner HBS 860 BB MG servos, on the tail I use a Graupner HBS 770 BB MG servo. These servos can be used with up to 8,4V and are fully HV capable.
The swash servos sit circular directly udner the swashplate. the tail servo is mounted into the the boom. Like this they can transfer their strength directly to where its
Directly behind the main rotor head is a small platform which can be used for Rx and fbl system. The kit contains also a small carbon platform where you can mount these two devices easily.
Because I use the Graupner GR-18 FBL, I dont need an additional Rx. I can adjust my fbl system easily directly in my transmitter via telemetry. In this case I
dont even to take the canopy off nor do I have to carry a laptop or a progcard with me.
The blades are the new Blackline series from SAB, which contains all the experience collected from team and test pilots. The blades come in different colour varaints and you can choose blades for your personal need (F3C, Sport, 3D).
I used the blades which were included in the kit, the 770mm 3D for the main head and the 110mm for the tail.
For all these powerful devices you indeed need a lot of power!
This is why I use Optipower 12s 5000mah Ultra packs with 50C! These batteries have a pretty long lifespan and immense power.
I fly them since over 2 and a half years and I can just recommend them to anyone who searches for really powerful and high quality packs!
