I got the CNC Heli V2 tail... I've never had a tail that came out of the package perfect. I mean, they even greased the thrust bearings! Talk about smooth!
The closest tails I've got are on the T-Rex 450 pro and the Velocity 50.
Turn these three tails on their sides, on the boom without the link attached and the pitch slider will drop, but there's no slop.

Ah, good job Jerry!! I thought I had seen those somewhere but would never have found the link!! Bill

How many amps will the electronics pull on the heli? Three mini servos, gyro, tail servo and RX. I had suggested using a CC BEC on my 600 and people said that the CC BEC would not be enough and I would need the CC Pro BEC. The CC BEC is rated to 5A at 24V 7A at 12V and 10A peak. The internal BEC on the ICE 100 is also rated to 5A. Ivan, to get back to one of your original questions, I use a separate battery for my electronics on my H550 so I know how much I put back in the battery after a flight. I have 4 standard size servos (3 X Savox SC-0254 on the cyclic and Align DS650 on the tail), a Quark gyro and an AR6200 RX. For 6 minutes of hovering I put back about 100-150 mAh. So, for an hour, that comes out to 1.0-1.5 Ah. If I have this correctly, that means I'm using 1-1.5 amps to power everything but the motor. I'm using the stock Gaui 3A BEC/regulator. So even for more aggressive flying it seems unlikely that you would need more than about 3A and 5A seems like it would be more than adequate. Savox says that my servos use 240 ma running at no load (couldn't find info on the Align). So 4 X that comes out to be about 1A for the servos. Quark says 75 ma for the gyro and I don't know what the RX uses but that all seems to agree with the 1-1.5 A range for the electronics. Don't know how much "load" adds to the draw. The stall current is much higher at 1.5A and some people say you have to cover that but that seems unrealistic. You should never reach anywhere close to stall current in normal operation and if a servo is stalled it seems like it means you've already crashed! As I've already said I already know that I only use 1-1.5A by direct measurement of my battery usage. Don't know if this helps or just confuses!!! Bill

That is some good info Bill. I will have to monitor BEC battery usage too and see what it tells me. The question is mainly for my T600s. The guys I fly with all recommend a higher amp BEC. The CC 10A will only provide 5A when fed by a 6S battery.
The Gaui will run off the Align ESCs BEC.

Ah, good job Jerry!! I thought I had seen those somewhere but would never have found the link!! Bill I know exactly what you mean Bill. I spent nearly an hour trying to find these when I started putting my 425 together, then forgot where I found them. Luckily I wrote it down in the back of the 425 manual along with lots of the other parts,pieces, etc that I had found in case I need them later. Jerry

Are there any upgrades for the vertical and horizontal stabs on the Hurricane? CF versions or something besides the white plastic ones? Mine is missing the horizontal stab but I figure if I am going to buy a new one, might as well make it look nice while I am at it.
Thanks again for any help.

Some more info for you Ivan... the stabs are identical on the 425 and 550 kits so the ones linked to above will work. On mine, I've got T-Rex 600 stabs because I'm using 92mm tail blades.

Very cool Scott. I keep forgetting I should be looking at 550 parts too.

See, that's really the cool thing (some might think it's cheesy, but I don't). You can have two completely different helicopters by just substituting a few parts. Of course, I didn't. I went nuts. Scott

Scott Actually, you can have 3 different helicopters. The short boom with 470XL belt for 425mm blades (which also uses smaller flybar paddles and tail blades) , The middle size boom and 522XL belt for 500mm blades, and the long boom and 575XL belt for 550mm blades. You can basically use all the same electronics too, except for maybe the motor as you would need a higher head speed for the 425, but you also have quite a few gearing options to change the head speed too. I have one running 550mm blades, and building a 425, but got almost enough spare parts that I might just build one running 500mm blades too. Most of the parts are the same for all of them. If you like a torque tube tail drive instead of a belt, there is one available for the 425 at AlleRC too, although I don't think Gaui has one yet for the 550.

hey guys, havent even got my 425 yet, and i bought the tork tube kit for it, i think i will just leave it as a 425, next will be the cnc head, i will get it all together and then look at the elec.
scorpion motor for sure 750 gyro scorpion esc spectrum ar6110 rx because i have one i got for free ;D the rest i will think about later

Are you getting the CF or plastic frame?

Looking for tail servo recommendations for the 425 plastic frame. It appears to be a full size servo opening... unless there is some adapter for putting a smaller servo in.
Planning on using a Gaui GU210 gyro.

Hyperion Atlas DS20GMD. It's full sized. I guess the person you bought your Gaui from didn't send the servo adapters. Let me know if you decide to go Mini servo (in that case, Hyperion Atlas DS16 series will do the trick), I'll send you the adapters I have when I get back from vacation.

Ivan, have you mounted a battery in it to see what the CG was like? I still have to tidy up all the wiring on mine, but with a 6s 2500mah battery strapped on, it was nose heavy. I ended up mounting my tail servo on the boom, and my BEC in the back of the frame where the tail servo mounting is. Just a thought.

Jerry Just be aware that you are risking more tail servo damage in a crash with the boom mounted servo because the Gaui boom is extremely flimsy. In both of the crashes I've had so far with my H550, the boom has completely broken in two about an inch or two behind the frame. That means the servo could go flying and may also get yanked on its wires. I've had aluminum booms bend and even crack open before but never completely separate like that. Just something to keep in mind. Personally I'd rather keep the servo in the frame (where it suffered no damage in either crash) and just add some weight to the tail if needed to balance. Then again, I'm more into reliability rather than performance. Just my $0.02. YMMV. Bill

I'm not sure if this info is helpful or not, but figured it wouldn't hurt to post it. I have used the z30 1500w motor on 425, 500 and 550 main blade setups without any cog issues at all with the plastic and c/f frames. I have always run with the tail servo in the frame though..using 2600 30C 6s Turnigy packs and never lost a tail servo due to damage in a crash. The only change i had to make were main blade, boom, belt, first gear, pinion. All the rest stayed the same (even flybar and paddles) and they all flew great once dialed in. The flight times are not the greatest on the 550 setup with that pack, but if you only fly 3:35 flights, (you really can still do a lot in that time frame) and the packs hold up well if not mistreated. 3600 6s 20 bricks and 3300 30C packs work great on the 500 and 40C on the 550 setups and cog is perfect with the servo in the frame.

Thanks a lot Scott, Jerry, Bill and Steve. All good info.
I have full size servos in the rest of the heli so I figure I will continue the trend.
I will be pairing up 2200mAh 3S batteries for this heli. I will do some CG testing and see how things look but I am leaning towards putting it in the frame.
