Assault 700 Flybarless Helicopter

The Assault 700 DFC Helicopter is Here!

Splash

When it comes to helis, size DOES matter.

Type: Collective Pitch Electric 3D Heli
Main Rotor Diameter: 1560mm
Tail Rotor Diameter: 280mm
Length: 1345mm
Pinion Gear: 13T

The bigger they are, the better they fly! Following the current trends, the Assault 700 is using a DFC (Direct Flight Control) rotor head which provides crisp, precise flight control with a very low parts count and easy setup. The DFC rotor head design brings the rotor disc closer to the main frame, moving the center of gravity closer to the middle of the heli. This provides better flight characteristics and more agility allowing for the ultimate in extreme 3D flight performance!

The Assault 700 is decked out with aluminum parts which other manufacturers normally sell as upgrades. The entire main frame is constructed from lightweight yet extremely rigid carbon fiber. The main shaft is supported by triple bearing blocks which are also constructed from aluminum. The tail assembly is all alloy and utilizes high quality NMB bearings designed for high speed use. The dually supported tail-pitch slider provides slop-free, precision tail control.

The electronics mounting design is well thought out on the Assault, allowing very easy access to the motor, ESC, servos, FBL system and radio equipment. The front cyclic servos mount directly to the bearing blocks keeping the design rigid, simple and tidy. The direct to swash CCPM servo linkages eliminate troublesome bellcrank systems found on other helicopter kits and offers precise, direct control to the swash.

The battery mounting system features a carbon fiber battery tray which is secured using alloy rails inside the frame. It allows for very easy battery swaps by sliding out of the frame with the batteries attached.

The Assault 700 DFC is mostly pre-built requiring only a few hours for final assembly, electronics installation and setup. We carry a full range of high quality components for this kit which can be found in the related items section below. [HobbyKing]

I really, really want this to be good. Unfortunately like other HK helis I'm worried this is just going to end up in an accident and/or replacement of the majority of the parts.

I have the HK 600 gt
I replaced the main and tail gear and put over 100 flights on it with 0 crashes.
After that 100+ I had a tail bearing go bad (most likely due to me flying it in a dry dusty backyard)
I fly only sport. But That seems like a decent track record for me.

I've seen this kit in person a buddy of mine has one, if you're going to do light flying and no hard flying than it's worth the money but if you fly any type of 3d it's not recommended, main frame isn't stiffened in the back which allows the boom supports to slide out and you have to drill a hole thru them and pin them in in order for them not slide out, and even with the boom supports modded and locked in the frame flex in back cause the tail to be inconsistent to the point were not even v-bar can sort out. But like I said if you do light flying thanx worth every penny imo.

There is something for 600 PRO:

Would it solve the problem if available for 700?

It looks like it has metal "floor":

i think it's a neat heli if you just want something big to fly circles around and practice hovers.i'd get one but it would probably be too big to fly in my backyard. and batteries are expensivewell, everything is on bigger models.

assault and battery combo.

I fly flips&rolls, some half piros, rainbows, low RPM nothing fancy.

In fact I want to stretch Assault to 800mm. We shall see...

Here is my earlier stretch, hundreds of flights and still kicking:

Nice job on the stretch 600! The funny thing is a bunch of parts are used between the 550 600 and 700 lol on the align kits . I always love reading about modified heli's . I have been making my own head dampeners since I went FBL. . I could never buy any stiff enough to my liking. The closest ones are the true blood green. Your next purchase should be the 7HV . I love mine , I bet probably flys like your stretched 600. .

Thank you. I bet you smack 7HV. I do not push my 700 hard. I just enjoy the size, sound, stability, speed and reliability.

My favourite 7HV video:
