I like everything about it,I dislike not ordering enough parts after I bury it!

Plus'
Fly's great
Part's availability
Cost
Support(Many have owned one)
Easy build-low parts count
Low maintenance(normally)

Minus'
Wiring(wires galore)

Be better if someone fixed it and I flew it

I dont like the play the balls n links get in them after several flights. If i remember correctly, the 600 had better links than the 700 version.

Thats my only complaint!!!

So far the only problem I've had with the 700N is the start shaft. It strips at the top at the collar far too easily as-is, all it has is the two little depressions in it for the grub screws. No matter how hard you tighten the screws down the collar eventually strips and carves a groove in the shaft.

grinding a flat spot in the shaft for one of the grub screws cures the problem pretty much completely. Two for both screws would probably be better.

apart from that, I can't think of anything I don't like about it or feel like it needs to be fixed. Nothing really broken on it....

What works for me: Install one set screw to align the indentations then apply loctite to the 2nd set screw, install and tighten. Remove the first set screw, apply loctite, reinstall and tighten, let cure and Im good to go.

If that dont work HOUSTON "We might have a problem"

Plus one on that buddy!
This is simplest/easiest way to get the set screws to set properly!
I've always installed it that way and "never" had a coupler come loose!
Good advice!

On the 700 -- Love everything about it for my level of flying!

I think overall its a great airframe.....although it would be nice to have decent bolt hardware that comes with the kit.....the stock links suck, I hate the servo to bellcrank links,,,,,make the new version direct servo to swash....that would make initial assembly so much faster. And it would centralize more of the weight around the mainshaft. And get rid of all that damn slop in the swash. Another thing that would be nice is a triple main shaft support. The metal le tail has a lot of slop.....that also was a mandatory upgrade. The clutch was a horrible blunder! Hmmmm did I forget anything....?? It was a good bang for the buck when I first bought it...but after I upgraded everything, I was in as much as if I woulda bought a jr helicopter...LOL maybe they might fix some of this with some revisions one day with a v2 of the 700n.....y'all let me know. Pigs will have pilots licenses by then I'm sure

Kyle clearly covered the DISLIKE part for everyone lol. Some of us have more issues with the kit than others but it all boils down to the quality of tools one uses, the amount of Loctite and force used to maintain/repair the model and the over quality of the model you purchased.

Did I forget anything?

700N
I've owned 30+ helis and this is my favorite. The links get sloppy too quick and I've had the one way bearing in the clutch that the start shaft engages fail. I'm not sure what the previous poster might think is wrong with the clutch and I've not had any other problem with mine. A third main shaft bearing would only add weight - I can't see what would be gained by it??? Direct servo to swash input is a good idea, but it wasn't that hard to set up as is and having the servos forward helps to keep the CG correct. Properly setup, the push/pull linkages to the bellcranks don't contribute to the slop in the system. I did strip out one of the side frame bolt heads in the three years or so that I've had it and worked on it. I've got good tools and haven't had that much problem with the hardware. Anyway, it's a great heli with good parts support and a low price. steve.

HATE the screws. The tail geometry is still off and the governor sensor is pain to mount inside the frame. The mod. 7 gears suck but the new 1.0 gears seem good. I have an original kit from 2008 that has been great since making a few of these changes. The V2 kits look very well designed.

I changed all of the rods to miniature aircraft. The rods are larger diameter and then i use the new align FBL links that are for the larger rod (swash to grips). Cheap fix for the 700.

Very well said steve9534,
IMHO There isn't a perfect heli or kit out there but with a good setup the 700n can hold it's own at the field and in the right hands put on a great flight. I have two 700's that have been trouble free for a longtime and love them both great helis.

OMG how much did i spend................

Pros:

parts (cost)
very durable!
very upgradable
fits all flying styles
looks great in the air!

Cons:

not the smoothest/precise flying heli
some align hardware is soft
wireing can be difficult

I own a few different brand helis. For a flybarred 700LE edition, I havent had one issue yet. Knock on wood though! I absolutly love this heli. Not one link has become loose on mine though. I have about 50 flights on it, and everything is tight as can be.

One dislike: The tail grips are sloppy and rock a bit on the hub. Im always afraid they will come loose or fly apart. Gears are decent, but could be a little bit less backlash in the TT drive system.

Although, its a beast!

Give the V2 tail a try... less than 30 bucks and world of difference.

That's not a defect though. It's because the tail grips have Thrusted Bearings in them. They perform the way they should when spun up, the centrifugal force pulls them outward and the bearings do what they were designed to do.

How does this new V2 version work?

One thing that will help with the bolts is a good set of hex drivers like the Thorp:

http://www.ronlund.com/rcheli-prod/TOOLAL/MIP9011.html

I have a set of these and they've paid for themselves many times over in no more stripped/boogered hex sockets in the heads of the screws on my helis. The cheapie wrenches from the hardware store, etc., are actually made of a soft metal and they round off almost immediately. Guaranteed to wallow out the heads of all but the hardest grade screws/bolts....

I've built 4 Aligns and have stripped only one bolt in all that time with these drivers (a frame shoulder bolt that didn't come loose because of loctite).

Overtightening is the other problem that generally leads to breaking of the bolts. If the wrenches are slipping in your hands (for 3mm or smaller bolts) you're cranking them down too hard and risking either breakage or stripping....

Each grip on the V2 has two radial bearings and a thrust bearing, and there is considerably less play in the component.
