Goblin 700 Competition (Blue Eyes) 4.9kg light setup

The Goblin 700 Competition was my first "big" Goblin. From the beginning I knew that I would add one to my fleet because a 700 is the perfect machine for events and shows, but also for serious training.

I was a bit confused and worried when I read the common opinions like: "The 700C is too heavy, minimum 5.2kg RTF". In Germany we have a weight limit of 5kg. So if you want to fly outside of an R/C club (like I do) you need to be under 5kg! When digging a bit deeper I realized that most of the guys put a lot of super-heavy-over-powered electric devices into the helis. 

So my goal for this heli was clear: To choose some lightweight but powerful devices in order to get a G700C UNDER 5kg!


Also in the big Goblin you get the clean and tidy look, we all know! Its just wonderful and looks so gorgeous!

The motor is placed in the front where it drives the main gear via a "big belt". The ESC is mounted below the battery with optimum cooling. The servos sit below the rotorhead for direct force transmission. The tails ervo sits in the boom. behind the main head there is a small platform for mounting Rx and FBL.

The motor is a Kontronik Pyro 700-52L. This motor is really lightweight (375g) but has immense power! I used it in nearly all my 700machines and it has enough power for 90% of us pilots :)

When you choose the 700-52L you will have the ideal motorshaft length for the built in counter bearing for the motor! The motor pinion can be changed easily, also the belt tension can be adjusted in a glimpse.

You can save immense weight with the ESC, too! I chose the Kontronik Jive 120 Pro. It has already a HV BEC and offers the beloved governor of the Kosmik! It is extremly tiny and lightweight (128g) and can stand much more than the written 120A!

I also connected a Kontronik TelMe to it, so I now have the possibility to read via telemetry on my transmitter all the data like: Voltage, amps, capacity etc.

The servos sit in a circle under the main head to deliver their power directly to the swashplate!

I chose Graupner HBS 860 BB MG for the swashplate and Graupner HBS 770 BB MG for the tail. These servos are ready for HV up to 8,4V and have lots of power!

They are also really cheap if you compare their data to other servos so this is really a secret hint to you! Try them!

The Graupner GR-18 combines a FBL system with an Rx. So you do not only save weight but also a lot of cable chaos! It has also a telemetry plug where my Kontronik TelMe is connected.

The best thing of all is: You can program the FBL via telemetry directly in your transmitter! So when you go out flying and want to adjust something you just land, open telemetry, adjust it, take off, test and fly. And all that without even taking the canopy off or pluging cables / laptops or progdiscs in!

Its the tiny innovative ideas which make the Goblin so special!

If you take a closer look into the manual you will find lots of possibilities how to wire your devices, where to hide the cables, how to fix them and a lot of other hints and tricks.

If you follow these suggestions you will be awarded with a tidy and clean looking machine which looks without canopy nearly as good as with :)

For the blades I use the SAB Blackline blades, which are included in the kit.

The Blackline is a complete new series of blades which allows best performance and flight feeling in both high or low rpm.

So my main blades are the Blackline 690mm blades and the tail blades are the 115mm ones out of the kit.

Of course we may not forget the main goal of this project: To get the 700 Competition under 5kg!

Thanks to the wisely chosen light but powerful devices (listed above) I could already save a lot of weight. But the last little bit I could achieve by selecting lighter batteries. For this machine I use Optipower 12s 4300mAh 30C packs.

All in all we come to a "ready to fly" weight of 4910g, means 4,9kg!
