Gaui X6

[B.Ewing]

I always see people suggest that 600s and 700s are close in price but I just dont see it. My 2 600s and 570 all came in around 2000 and my e7 had over 3 in it

The best call for gaui would be the 550/ 600 stretch route!

Big ESCs, motors and batteries make a difference. By teh time you go from a 3.3 or 4k to 5k battery, for a couple 12s stick packs, you're in for a hurting.

Blades, servos and replacement parts tend to have minimal impact with most manufacturers.

The biggest heli I own is the x5. I had an n5c but just was afraid to crash it with the repair costs. Going from my x3 to x5 i'd say crash costs double. Going from my x5 to n5c, I didn't want to find out. hehe.

I am interested to find out what the x5.5 feels like. But to be honest i love flying my x5 that the x5.5 is just curiousity at this point. If at a funfly someone gave me their tail to slap on my bird and some mains, I woudl do it, but I doubt i would do it on my own.

What are you basing this on?

Motor
Scorpion HK4035 for 600 = £160
Scorpion HK4525 for 700 = £235

ESC
YGE 90HV for 600 = £185
YGE 160HV for 700 = £320

Blades
Rail 606 = £70
Rail 716 = £93

Batteries
2X Gen Ace 6s 3300mah 45C = £126
2X Gen Ace 6s 5000mah 45C = £220

That is a saving of £327 plus the saving of the initial kit price you could buy three more flight pack sets with that.

My x550 fly great. Ton of power with 4025-630 12s. I can can pply fit 600mm main on it with out problem. I know it can tie 570mm but I don't see the need. Larger main will need larger tail. At the moment I have 92mm tails. X5 stretch is a simple mod that take less than 30mins to do.
I like the 550-600 size. 500 is bit small and 700 is too big. I hardly fly my g700. X5 stretch is a lot cheaper to crash than a x7 or g700. My only complaint is the x5 flight time.3-3:30.

What size packs do you fly and what hs?

I still can't understand why it didn't happen?

I dont blame Gaui not coming out with an X6. New frame cost money to design and make. Using x5 frame we will complaint. Use x7 frame is too big. New larger frame will be heavier.

Worse heli for align and Sab heli are the 600 class. 600 size dont sell as much as 500/550 or 700.

Yeah, I've spent a few hundred dollars and around 100 test flights trying to figure out a 3D viable X5 stretch. But unfortunately nothing I could do would keep the power and torque of a 12S motor from stripping the main gear with 600-610mm main blades. I even had the tail gear strip out a few times. When gaui released the motor mounting plate for a 12S motor and the new black gears. I was fairly confident a "X6" stretch would be possible. But it seems like people were stripping gears while using 520mm blades on 12S. So now I feel like they released it just so guys like me could guinea pig it or something.

BUT, as of right now I have put about 50 flights on my X5 stretch while using 570mm main blades and 95mm tail blades and being powered by a 6S 4125-1100 Quantum motor and 100A ESC. This setup hasn't stripped a main gear so far. I did notice some wear on the front TT gears after about 30 flights. But my mesh was pretty loose. So I replaced the gears and fixed the mesh. The last 20 or so flights haven't shown as much gear wear. I'm fairly confident that this stretch is going to be viable for me and how I fly. There is plenty of power with the 1100kv 6S motor. The heli is soooo light it isn't funny and flies pretty powerfully at around 2200 RPM governed. I picked up my buddies Goblin 570 and my X5.7 back to back. I was surprised at how much heavier the Goblin felt. This is also reflected in the air, as I had to get used to the extra floaty feel of the heli compared to my X5. I was using the stock Gaui servos and they felt okay, but I had to go to 125% DR and like -10 or -15 expo. So obviously i need to put better on there and I think the whole thing will feel better. But it still is super floaty feeling. I almost didn't like it at first, till i got used to it.

As far as a "X6 stretch" goes. I think 570mm blades and being lighter than anything is close enough for me.. 6S seems to be more than enough power and there is a noticeable increase in air presence. The heli would look even better if I was using a Formula canopy. But I have sooo many original shape canopies i picked up on discount for $25-30 over the last 2 years. So I might as well crash those up first, right?

[SMJT]

What sells it for me is that 600 size helicopters flies quite similar to 700s.

The size of the blades gives the heli a direct response feel like a 700 and the added weight gives a more precise movement that smaller helis just don't have.

[FailureToFly]

Are you stripping the black gears with 600mm blades or the red?

I don't think anyone is stripping the black gears on 520mm blades.

I have run a 12S 4035 setup for over 2 years now with 520mm blades without even a hint of a strip with the black gears. Even in a crash the things barely even strip they are that tough.

It is at the end of the day a 'true' 500 size heli so I wouldn't personally trust the mainshaft etc with 600mm blades and hard 3D flying...let alone the TT gears etc. It's a tank of a heli but putting much heavier 600mm blades on it is akin to dropping a small V8 into a hatchback. Lots of fun certainly but a little prone to issues!

Failure to fly, how much headspeed do you use?

Can you list the parts which you have on your heli? Did you stretch the boom or just slapped 570mm blades on there and 95mm tail blades? Which blades are you using?

[Trexwilly]

I followed his thread on rcG and he did it all right, but if your going to push on it, the main gear is just too small, with not enough pinion to make a good mesh...

[FailureToFly]

From about 2350-2700. I usually am in the higher end of the range as I don't currently use a gov (I just rely on the grunt of the 12S setup) and run either 80% or 100% TC.

Thats with 520mm blades right?

[FailureToFly]

Yeah 520's.

I could swear I read or heard about people stripping the main gear with 520mm blades too. But I was stripping the black gears like a hot knife through butter with 610mm blades. If i used more than 10° +/- pitch range It would strip pretty easily. At 12° +/- range I could strip the whole gear bare of any teeth at all in a single hard pitch pump. I could also do it pretty easy even with 550mm and 570mm blades with those pitch ranges.

Anyway, I agree with you that 600mm is too big. I just wanted to see how big i could go. I actually was using Spin 610mm blades. They fit the grips without modification. I think even 570mm is probably still pushing it a bit past maximum limit for this airframe, gearing and shafts. But it seems to be taking 570s on 6S fairly well so far. I'll know more after i put another 50-100 flights on it.

For anything bigger than 530mm or so you have to stretch the boom.

To stretch the boom I used a Gaui X7 tail boom and torque tube cut to size. You also need the X7's front TT gear bearing block for the boom because the inside diameter of the X7 boom is different from the X5 boom. The X5 front TT gear bearing block won't fit the X7 boom. Other than that, you just cut the lengths you want out of the boom and mount the blades to match.

I was using SAB 570mm Blackline main blades with RJX 95mm tail blades. But I've been wanting to try the Zeal blades instead.
