Makes one wonder when you ramble and use such poor grammer; especially even with the issues the heli had/has no one has come close to calling the heli crap.

Parts quality, fit and finish, style, engineering, and pure originality of design, put this helicopter in a league VERY few can match. It does require careful assembly, and attention to detail to get the best from a Kasama (as is the case with other kits).

Pretty darn unlikely that the crash was a result of defective materials, or workmanship in the kit. What does that lead one to suspect?

Not sure about that.
It's got a long history of issues with starter shaft, engine mounts, TT drive, tank foaming and certainly known to strip gears.
Despite that, I will be getting an ECO 90 FBL soon.
I am a sucker for challenges.

Tiny I think you just got a kit that wasn't put together right.
All the problems you have stated I have not heard anyone mention. Maybe the person you bought it from didn't know what they were doing and messed some stuff up. You did have a very early kit with none of the upgrades.

We are so lucky there are still Tr*x 700 around for people who just want to fly at the expense of some limitations. To each its own.

I agree with Fender here, old kit with old starter shaft problem, plus something not built right. These helis don't fall in place together as Ali*ns, they need careful attention in several components throughout the build, after parts settle, and as regular maintenance. I experienced problems myself and I am a pretty advanced modeler.

However, I like the challenge as much as flying, so I don't regret a single minute spent working on this heli. Once you get to know it, and this requires time spent with the machine and problems to be had and solved, it's a very rewarding heli, well worth the effort. I admire mine, truly.

I completely understand if that's not your thing Tiny. I would get the crown gear from you, but I am too far away to make it worth the effort. Best of luck.

PFFFT What limitaions might that be ?

You Kasama guys. You know those pretty little redundant arms, that control your swash links, that is held on by one poxy little grub screw ? Twice ive seen guys about to fly, and they cant figure out why the servos arnt centering anymore. Its that little arm comming loose on the shaft. I dont consider that inovative. Thats design for designs sake. Completely redundant as a control technique. Thats just ONE lol

Its too hard to get big helis reliable, without stuff( i would say junk) built into the kit. No wonder for their small volume of sales, there has been so many problems with this heli, even from some of the most experienced builders going around.

T700 has limitations LMAO

If I would have gotten a raw deal from the manufactuer, I would be pissed to say the least and if I mispelled somthing, the last thing I need is someone to check my grammer. Nothing positive or productive to say?? Go away!!. He is very educated and probably makes more money than you.

tiny, crashing sure sucks, but it doesn't make sense. If the heli was rock solid and all of a sudden hits the dirt there must be a reason, most likely build or setup error, sorry if it's not what you want / what you're ready to hear.
Some parts may be defective, but then you have to spot them and Kasama will change them as fast as they can.
You must build this heli correctly, this is no Trex 700, and not a throw-parts-together-and-fly kit.
Nothing to bash a brand really. IMO this is the finest heli I've ever seen.

Actually over here, they are selling very well.
To the point that at least one of the Suppliers has run out of the ECO FBL version.

On our forum we also have an active Sub just for the Kasama helies.
Most who have them, have had some issues and I am quite critical of that considering that it's suppose to be a top of the line heli, at the same time I am also not aware of any of the users not having been able to sort it in the end.

One of the main issues I have seen now is the stripping of gears. I know this can be prevented by multiple times re-setting the gear meshes but at the same time, take any of the MA helies like my Stratus and this is a none issue.
Even TT's like my Raptor SE50 doesn't have any of these issues.
It seems to be more an issue of material selection then being the problem that then consequently requires such a high attention to these parts.

In regards to gear mesh, my RJX50 is the same, but once you are aware of it and re-set them after the first 3~4 flights, it's then good for the life of the gear.

Kasama is still a Newcomer to this field (in building full blown helies, not parts) and it will take time to refined their choice of material selection and design.

You can see how Kasama is constantly actively updating/upgrading the parts that are causing issues for some.
The same was happening with the Aurora so this manufacturer should certainly been given the chance like everybody else to sort things out.
When I order mine soon, I will walk into it with open eyes and will take a different approach to building and testing then on a more proven design.
I am looking quite forward to it.
The last heli I build took 2 years to sort out, but is now one of my favorite helies next to my Stratus.

Okay now i'm getting mad, something went wrong with the heli because of a setup issue(Builder Error). Im calling setup failure because he told me what happened ON THE PHONE! The main gear pulled up on the frame(Builder Issue). This caused the RPM to drop to the point of no control, and he did say just prior to that it was running very smooth at 1900 RPM. Don't come on here bashing a product when you don't have a freaking clue what your talking about.

The set screws on the control shafts do not come loose if you use proper torque and lock tight(Builder Issue).

The material used to make the parts alone on this kit are far superior to 95% of the other helis out there.

I was the same way at first, then I figured out my same setup tech that I have been using on more simple helis wouldn't cut it.

Groran,

Poor grammer, rambling and mispelled words all go to show that a person does not pay attention to details. This is an important attribute to have in this hobby.

If you want to be taken seriously and English is your first language then taking the time to format your words in a reasonable fashion would not be asking too much.

The control system as designed into the Srimok has no redundant parts. Everything in it has a specific purpose. The pitch and aileron servos are better isolated (protected from vibration) due to the dampened frame they're mounted in. The torque shafts impart a pure radial load to the servos which are also trauma protected by the thin metal disks. This also allows those servos to be mounted somewhere other than directly under the swash arm they're controlling.

Servos don't live very slop free lives when controlling the swash directly due to the shear load imparted to their drive output shaft, and they take a very hefty "hit" in the event of a crash. Kasama's control system has the precision of a direct servo to swash implementation with improvements in durability, and crash survival.

I realize that not everyone can appreciate the design sophistication endowed upon the Kasama machines, like a good friend often said "whatever blows your skirt up". Personally, this is the finest brand of model helicopter I've laid hands on.

kasama eco
I have building an eco 90n cyberhead for the past week.
As far as building they are pretty time consuming and they really assume that you have had quite a bit of experience building helis.
I knew this going in though and have just been taking my time trying to get things right.
As I really havent seen a completed one in the flesh has taken a bit to get my head round the drawings as its pretty different to the other helis i have.
Love the thrusted main bearings, high light for me anyway.
Regards the poxy arms they do stipulate to red locktite the arms to make they shaft more durable as they put it and i agree after having mikado helis that direct swash control is the simplest way. I will let others argue whats best as i dont really know.
Anyway my 2c worth.
