I have an NX4 on the way and I should get it this afternoon. This will be my first Nitro heli and I am pumped I ended up purchasing the combo that comes with the mini vbar and Gaui servos. I know I could have probably saved a few bucks buying the kit and parts separately but I wanted to try the Vbar and servos. The only FBL experience I have is the 130X and my 550 that has the 3G unit. I also purchased the OS 37.

I have a few questions. I have never setup a nitro. Do I need a governor? If so, what does it do and what is everyone using? Is there anything I need to look out for during the build? What would be the best sounding(quiet)and performing pipe?

Thx for the help,

Build is fairly simple, I used the Gaui Govenor, It keeps the head speed constant during different manuvers. Pipe is your choice. I have not maidened mine yet so I cant say the pipe is good or bad, I used the Gaui Pipe.
If you have any questions during the build feel free to ask!

Usually the combo is the less expensive than purchasing all the same or similar items individually.

Hello Andy,

The stock pipe, (From GAUI) is cheap and Quiet.

The Hatori pipe is a little quieter, but way more expensive, with about the same power output as the GAUI.

As for the gov, you don't need it if you can program a good throttle curve. If you don't know how, I suggest a gov.

Rev Max
Throttle Jockey

Are all good Govenors.

Xpert Servos
PowerMaster Fuels
YS Engines
Castle Creations
Scorpion Motor
VTX Blades
