Default Gaui x4 build

Hi folks
I have just picked up a gaui x4 kit and am looking for information on the ar7200bx ( which is out now? Or not?) I hope to use it and any experience with it or the x4 build would be helpful. Any ideas and areas to avoid would also be appreciated!
Sorry for posting this here - there does not seem to be an x4 or general gaui spot yet?
My build is just starting here http://www.rccanada.ca/rccforum/showthread.php?t=134573
Cheers

Nice I am curious to watch this build and see what you think. Keep us posted here. MODS... Please make an X4 Sticky now that we can get it in North America.

it's out, i hear the fist batch had issue and went back, so the release date got pushed back

honestly thats allot of stuff to fit in a little box, i would wait awhile to make sure there are not any issues, when you buy something brand new you are kind of the crash test dummy for that product..

Good thought re the ar7200bx
Crash test dummy is not completely inaccurate for me - I like to think of it more as a stress testing professional. I sure like the idea of a combo unit Though!
I will post some pictures here.

There several x4 threads in the 425 section. Hopefully helifreak will create a forum for it once it gets a bit more popular.

I too am considering an x4 to go along with my other "x" GAUIs.

I am still considering it.

I have requested that we put a X4 forum. If you think so back me up and post about it.

I am going to wait the reviews out before I get one.

Then again for the cost, I might as well get another X5.... Hmmmm.

I agree, an x4 forum would be great!

I really want a 500 size helicopter also because I have a difficult time seeing my 450. I bet the x4 is a great helicopter, but the price of it vs the x5 has me on the fence as well. Hopefully they come out with a super combo in the US for this summer!

Default X4 Unboxing

A few photos from the unboxing.

excerpts from the build thread - http://www.rccanada.ca/rccforum/showthread.php?p=908422#post908422


....The Scorpion motor can is a thing of beauty. Someone did some great artwork here. Inside the can is a GM-504 motor, bullet connectors for the ESC and 3 decals. The motor was sealed in a bag - it has a thin film of grease/oil on it. The gold anodizing has a rich and quality look.

The ESC came bundled with instructions that are in perfect English. That is nice. The 66 amp unit is good for up to 6 cells and has an onboard SBEC which will deliver 3 amps at 5 volts - plenty.

The box that contains the kit is inside a sleeve that was a bear to get off - tight fit. Once out it opens up to a canopy and a manual and nothing else - it looks empty. A section on the right lifts up to reveal a large single bag with almost all the parts in it. Only the long pieces are loose in the bottom of the box. The big bag contains 19 smaller bags that appear to be very well organized. I will open these as I go. Thread lock and grease is supplied along with things like straps and blade holders. All major components (i.e. the head) are assembled. These will have to come apart for threadlock and lubrication.

The photo of the canopy below does not do it justice. It has a deep red fading to light scheme which is eye catching. It is also very narrow. From what I have seen so far, in the box and on the web, this will be a narrow Heli!

The instruction manual is clearly printed and came with servo wire wrap stickers to identify each.

Cheers

Does it bug anyone else that the "X4" looks like "XY"?

Default X4 - impressive

So far I am very impressed with the x4. Its on it's gear now and motor and main shaft are installed. I will get some more pics moved over.
It incorporates some really good design ideas. You can swap out the rear umbrella gear without taking the whole tail apart - very cool.
I also have a real sense that it is a quality machine.
Cheers

I'm disappointed they didn't fix the OWB design while they had the chance. The extra small bearings and fragile OWB gear/bearing will no doubt start causing problems just as it did for the hurricanes.

At least before the X4 I could understand trying to keep everything compatible between the CF and plastic hurricanes but now there's no excuse. Too much of a liability on an otherwise great looking machine.

It swings 425mm mains, more like what Align calls a 500.

Default Servos and Head

I have run into some challanges and am on hold now and will be in touch with Gaui - this should be interesting! I am stuck.

excerpts from the build -http://www.rccanada.ca/rccforum/showthread.php?p=909881#post909881

...Mounting the pair of servos looked easy from there. This is what that long bondhus driver is for - the motor is in the way and you have to hit the heads at an angle. The long 14 mm screws supplied in the kit are unfortunately not long enough and simply stripped 0.97 mm of thread out of the head block when I tried to tighten the first one - guess I should have checked the length before trying. The hole in the block is 3mm deep. The screw protrudes 0.97 mm from the pair of servo....

....I shortened some 18 mm bolts and secured the two front servos. The rear head servo went in easily with the same oversized arms...

The rudder servo requires a long arm? My understanding of Gyro and rudder servo combinations is to keep those arms short. It won't work on this heli as designed because the rear cover plate and spacer block the exit for the rudder push rod if you use a short arm. You have to use a long one to clear the spacer and get the rod up near the boom? I have no idea how I am going to get the ball link on - it is covered up and very hard to access unless you take the arm off. This would not be too difficult but the long arm that came with the savox servo (see previous post) has more meat on it then the standard arms and the screw barely makes it through to the splined shaft and of course started to strip when tightened It is now CA'd t o keep it from loosening - removable for sure but less than ideal.


The head and swash plate components are generally threadlocked. So far I have not been able to get the blade grips off. I have heated them and torqued them as much as I dare. They are not budging. I am concerned I will damage them and will be in touch with Gaui before going further.

Plus

The head does not fit on the main shaft - no way. I have lubricated the shaft - the hole is too small when you get about half way up the shaft. There is a partial shoulder there which is part of the compression/grip system. I suspect it will need to be drilled or milled out - Again I will be in contact with Gaui before Proceeding.

I am on hold and keen to hear from Gaui on how they suggest I proceed?

Interesting - there are also quite a number of unused holes that look like they have redesigned things - the servos are not centered in the cut outs either - nothing like building on the leading (bleeding) edge.

Also - not sure how i feel about having to threadlock servo screws. I hope they won't need heating to get out - plastic may not enjoy the experience.

Sorry to hear that you are having issues. the unused holes in the frame are for a belt driven tail mount - in this case there would be a bracket above and below the belt, whereas both of yours are below for the TT - this was the same on the H425XF carbon framed 425.

Default Extra Holes

Hey Mike J
Now worries I hope - I have an email into Gaui (everything shut down there for new years this week).
I kept going with the tail which is really nice. Very well done.
Thanks for solving the mystery of the extra holes. I did not know they had an X4 belt driven machine. Do you know what the ones near the head block do ( in its other incarnation?)
Cheers
J
