Funjet 5S part 1: setup / mods explained

Lior Zahavi showing the mods and electrical setup of his 5S Funjet @ 1400W of power !
In this video you will see exactly what it takes to built an extremely fast Funjet (about 230Kph), and i gurantee its much easier than you might think !

Hope you like the video.

This setup includes:
- Medusa 028-040-2200V2 motor with heatsink
- Castle Creations Phoenix80 ESC
- Medusa 6V 2A BEC
- Ino-Lab HS-D202MG digital micro servos (elevons)
- Cheap chinese digital micro rudder servo
- Thunder Power 5S 2250Mah 30C Pro Power Lipo
- Futaba 10C with Assan 2.4Ghz module \ Rx

Again, this setup draws about 75A and makes about 1400W. it is the most powerful FunJet i have ever seen or flown, by far !

Nicest thing about this setup compared to other setups is that its still very light (AUW is 790g) and flys slow really well !

Enjoy.

I built mine almost per this video and with fantastic results, even after alot of "experts" on R/C groups told me it would fail, a year and a half later the same battery and motor scare the hell out of everyone at the field week after week with no improvements except new tape on the belly, and radars at 138

@giffordig glad to hear you like it - it does work well :)

Excellent info. I have built mine similar to yours, using a Turnigy power system and a 5s-2200 LiPo. We are experiencing extreme torque from 1/2 throttle to full. We have tried a throttle to aileron mix with little success. Any suggestions?

thx much and Shalom..........

Here are few pix of my FunJet

Notice that we are bungy launching......CAUTION....laun­ch with NO power, add 1/4 throttle after clearing the Launcher....

@BocaPhil how come aileron movement cant correct the torque ? this sounds strange...

[BocaPhil]

@i3dm It is strange...can't seem to get the amount of aileron correct. 30% toomuch, 10% not enough.....we'll figure it off.

Thx

@BocaPhil i use a curve based program mix where i can set each point to a value which i check in flight - you can usually get it nearly perfect.

just maidened my funjet today, only running 3s, 2700 kv motor, and 6x4 prop, bout 400 w, but really impressed by how well it tracks, but also really would have liked a rudder, and this mod you did gave me a great insight how to set it up. great vid, thanks
