For anyone who's interested here's my take on the Gaui 200 V2.

I'd never been too interested in micros but I brought this on a whim and because I was offered such a great deal on it, it was hard to say no. I paid under £120 quid and all it needed was an Rx & Gyro, it even came with a 2c lipo.
I had an old GY240 kicking about and brought a 2nd hand AR6100 from a memeber here and I was good to go.

I read up on it and although it came pre built decided to give it a good going over and a bit of threadlock. To be honest it didnt really need doing, I found that all the screws were pretty tight and it could probably have flown as it was. I did manage to strip the thread in the ally boom retainer block trying to get the tail & belt tight so had to insert a longer bolt and put a nut on the back.

What I would say is that a lot of the screws are philips and not hex headed and you need a tiny (I'm talking watchmaker here) screwdriver to get them on and off, so I am in the proccess of replacing them with hex's.
Also there are a couple of brass bushes between the headblock and the blade grips which you have to be careful not to get threadlock on as this makes the head sieze up.

The original setup gave me +/- 12 degrees of pitch which I dialed down to about 9's as a start point. I tried flying it at that but it was so incredibly twitchy and resposive it was almost unflyable. That coupled with a manky GY240 I was getting nowhere fast.

After some research I decided to replace the floppy plastic blades with woodies £4.00 and fit a longer flybar and bar weights £3.00. This improved it remarkably, it was still lively but hovered much better.
My problem was now the gyro, at first I had installed it on the baseplate just forward of the main gear but I was told it needed to be further forward, so I moved round the electrics and this helped a lot as I could easily get to the manual gain adjust pot and the gyro itself responded better.

I brought a couple of extra lipo's £10 each and took it to my club, it flew ok for a few minutes but in my excitment I stuck it in.
Broke the blades and bent what I thought was the feathering shaft, but as the feathering shaft is contained within the headblock all that bends are the set-screws that hold the grips on which are quick, cheap and easy to replace.

With my new blades on I set about the gyro, but it seemed no matter where it was positioned or how it was set I couldnt get a happy balance between twichy and loose.

Having decided that the GY240 was never going to cut it, I bit the bullet & brought a Gaui GU210 gyro. With a couple of minutes setup she was flying perfectly, solid tail and I was very impressed. It is very fast even with a 2c on it and its very easy to blast down the field and lose sight of it in a couple of seconds so it has to be flown reservidly.

To date I've only done about 8 packs through it, how it stands the test of time we'll have to wait and see but my first impressions are that it is a well made, strong, little heli that flies nicely considering it's size. I'm not sure I'd want to fly it in my front room but a large empty garage would be about my limit.

If you are thinking about buying one of these here's some things you might find useful in the early days.

[I]It is worth getting a file on the canopy and getting it to sit perfectly on the frame, mine fitted out of the box but it was a bit tight which led to some stress cracks after just a few flights.[/I]

[I]Headspeed is your friend, run it fast, my idle ups are staright 100% it looks insane to start with but believe me it flies best at that.[/I]

[I]If youre looking for a nut for the boom retaining bolt its the same size as the Align locknuts for servo balls.[/I]

[I]After a crash even if the boom looks straight change it anyway, they're only pennies to buy, and if its just a mil out it shreds the tail belt.[/I]



Even with a massive amount of dumbing down it's certainly not ideal for a beginner but for someone who's got a bit of experience its good fun!
