Default X4 vs 500 elf

I am really enjoying both helis. I am pushing the x4 hard now and it flys really well. Very fast! I will do another video soon. The ar7200bx is working great and I have not adjusted anything since initial setup on the bench. It's rock solid.

There are still some bugs to be worked out in the engineering/construction of the x4 and from a purely financial perspective the trex 500 was significantly less expensive. You can't beat an align kit for engineering quality. The new Align canopies/ mounts are not good in my opinion on the 500 or 600 (nice looking, but a real step backward in terms of getting them on and off and the 500 cracks like a frozen lake in April) and the 3GX instructions leave a lot to be desired. We need a good 3GX setup video that includes the interaction with the
head as it is setup. One day Align may even have a customer service dept as well - wouldn't that be great (pet peeve - sorry had to throw that in)

Overall the Trex 500 comes out ahead - less expensive, great parts availability, excellent engineering.

My two cents

Default Savox Align metal gears

Hi

I picked up some 2650 6s 35-70c Nano-tech batteries from Hobby King to try in the Trex 500 and X4. Flight times are very short - figure 4 1/2 minutes max. The Gaui ESC spooled down to about 1/3 - 1/4 throttle very suddenly near the end of the first flight and I was able to get the Heli on the ground but brushed the grass with the blade tips. Not a scratch or even a mark on the blade but a gear stripped in the right hand forward servo CH2 (aileron).

The Savox 1357's are advertised as cyclic servos and come in three packs for 500 size helis. they move very easily with just the slightest touch of a finger and I was wondering how they would hold up with plastic gears driving the head directly. I did some reading and it seemed that metal gears are not available from Savox (could not find a source) but they are for the Align 510(m). All indications were that the Align servos are made by Savox so I ordered up a set of HSP51032T DS510M servo gears.

The installation of the gears went smoothly. I counted and compared teeth and they appear to be exactly the same. The Align metal gears are a perfect fit and work the same and at the same speed as the original (in the cyclic) with slightly less play. I lubricated them with high quality white grease. I compared a non-modified and a modified servo side beside and could see no difference in speed when moving the sticks as fast as possible. After powering up in the Heli the head is fast and precise in its movements.The center servo arm screw is a 3mm thread size. The metal gears added about 1 gram to the weight of the servo.

They have a very different feel now when powered down. The originals move with a feather light touch and the modified metal have a much more "geared" feel to them. Servo test flight coming up, and expecting good things.

Default The X4

I had the X4 out at a 2 day heli event on the weekend and I must say it was a very popular machine. People were impressed by the looks, design , and power/speed of the thing.

I was hoping for more video but can tell you that those that tried to record it couldn't keep up with it.

Just an FYI
Cheers

Hello, I am French.
I recently purchased a kit Gaui X4.
I encountered the same problems outlined at the beginning of the page.
I, again, a clearance of a few tenths of a millimeter on the axis is placed or the freewheel. I will address by placing a shim.
Sorry for my English (Google translation).
Sincerely ...

Hello,
I found a game on the vertical axis: "One Way Gear Shaft" which does not affect the operation of the helicopter.
This game is not normal for me, I remedied by inserting a washer 8x10x0,3mm below the ring: P8.1x9,6x5,3.
I tested several shims and it deletes the game without blocking the pinion "One Way Gear" which is used for autorotation.
Regards and good flights.

Google translate isn't always flawless, I think you mean "play" instead of "game" ;-)
My Hurricane 550 which has a similar one way has the same play, it can be hazardous when the aluminium spacer/tube gets compressed, I have had some gear strips as a result.

hello,

"game" = floating the vertical axis.

I made very sure that the washer added in no way disturbs the operation of the freewheel and accessories on this axis.

cordially

Thank you .

René

Hello,
sorry for the translation (Google) ...
I have not been able to steal my X4 for about three months ...
Until now, the rotor speed (rpm) that I used was 2740 rev / min ...
Last summer, the engine reached high temperatures and reduced autonomy "3 minutes 30" 6S 3000mah lipos with 45C!
Disappointed with the results, I decided to change the motor and controller ...
Passage of the "Scorpion 3226/1600KV" and "Talon Castle Creation" ...
I think not to be disappointed because the engine "1400" and a rotor speed of 2740 rev / min, I used 92% of its potential. With "1600", I use 81% ...
Hence a consumer economy and less heat ...

As soon as the weather will be favorable and that I could fly, I would give you the results ...
Last thing, many owners turn NX4 with rotor speed (rpm) 2500 view 2600 rev / min ... Which rotor speed (rpm) do you steal your X4 ...

With thanks ...

Sincerely ...

@+ René
