Synergy N556 Flybarless Nitro Helicopter Kit
All carbon and alum built heli designed by a rc heli pilot. Strong, light, functional, stylish ... if your looking for a top shelf 55 heli, here it is. Make no mistake, the looks and the engineering are amazing but nothing in comparison with how it flys. Hands down the most predictable, linear responding heli ive ever flown. It only does what I tell it and it makes it look good when I do it. But wait, theres more! Synergy's are known to be smooth and this one is no different. Would you believe this heli sounds,feels and looks as smooth as an electric? Neither did I till my maiden. All I can say is im blown away every time I fly it.

I knew in advance that this model was one I wanted so soon after Matt Botos announced it I collected parts. I went with just about everything he recommended minus the pipe.

The heli flies fantastic as a 556. I have yet to stretch it to a 600 and probably won't as I like the little bit higher disk loading you get from it in 556 format (can get windy here in Iowa).

If you have built one his models this one builds just like it and has the new rear transmission which is a lot simpler than the old classic from the N7 and E7.

The only weird thing I ran into was a bit of what I thought was vibration issue. Ended up being the blades were way to tight. Once I loosened them up the issue went away.

If you want to try nitro this would be a great heli to purchase!

Awesome nitro 50 size model! It was a pleasure to build and the quality of parts is second to none in typical Synergy fashion. Just make sure to pick up a boto sizer ball link sizing tool as all plastic ball links will need to be sized to fit! and only required 1.5 turns for each link. This model fly's amazing and super locked in!
