OK.. A good one to get things going...
I have a stock 550 and want to upgrade the motor and ESC come the New Year. I hear the Z20 is a good option for an upgrade and I was thinking in conjunction with a Castle Pheonix 80A or even the Ice 75A.
I have read that the Z20 is matched to the stock 50A ESC. What about the Z30 and a 75A or other combinations of Motor/Speedy
Thoughts/suggestions?

The Z30 is rated at 60amps so I would suggest going with a 75 amp esc with the Z30. Both of these motors get great reviews on the Hurri 550, but the Z30 would be better for aggressive flying as it has more power than the Z20. |

You're at the area where soon, you're going to want more power, soon. If you ever get the change, I'd go with the Z30 and the ICE. Oh, yeah... and Christmas morning, balance, then strap on those CF blades!  Scott |

so far the ICE line of ESC's has been a good option... but don't try any other CC ESC or BEC in your hurri... they for some unknown reason don't play well together and just about every burned up hurri had a CC product in it...
as far as motor options... the Z20a-980 is great for sport flying... it's not a slow poke either.. I'm running one at 2300 RPM... but it will bog a bit.. for pure power, the Z30-1110 is a proven motor... no bogging and runs a LOT cooler than a scorpion or stock gaui

Mystic speaks the truth, Jon. The TonicX motors are really good. Dude, one thing I keep forgetting to ask you... do you have CNC grips? If not, before you go to a higher head speed, get the grips.
Mystic, a question for you that's related to the above... Is it safe to run say around 2k rpm with plastic grips and CF blades? I think so, but I'd hate for Jon to be disappointed or worse, hurt.

I fried 2 CC 80A ESC's and 2 CC10A BEC's with my Scorpion 3026 1400 (still have burn marks on my CF frame).....(I would have to type for an hour to try and explain all the details) but both times it happened on spool-up....it would work nicely for awhile, then just decide to smoke. Then I went to an Align 75A ESC/Sport BEC and have had no worries since. I also Traded my Scorpy for a Z30 1110....sweeeet!!! Bill |

I've actually been giving a bit of thought to the CNC head as - yes, at the moment it still has the stock plastic. The way I'm going I'm going to snap them. Especially when you add the carbons - somethings gotta give!  But I think the upgrade will be the complete package as in: CNC head Z30 Motor CC Ice 75A Not sure when though...  I have one day left at work (Thursday 24th) and we may well finish early - which means i will probably be out of action for a week or so. I will try and get on the PC at home (I do want to practice on the sim). Watched some Bobby Watts videos today - each time I watch the 3D stuff - the more it makes me want to be able to do it - even if it is mild! |

Also, Jon, you can get the grips seperately or in the Ultimate Performance kit. In the performance kit you get faster paddles, too.

Scott can you run 2000rpm on plastic grips... yes... the real question is how long can you run plastic grips at 2k rpm... that answer is long enough to get used to flying it like that and then BOOM the heli self destructs in mid air.. ask Ben (Wazzer/Head Hunter) what that looks like. Plastic grips on the Hurri are fine for lower head speeds (1600-1900) and work great with woodies.. when you start cranking up the head speed and flying with CF blades you really need to get the CNC grips.. if for nothing else its safer.. |

Thanks for confirming that, Mystic! If you've ever seen Jon's flying, he's getting to the point where he's doing some very cool stuff! It's has been very impressive and inspiring watching his progress! Scott |

I am planning on buying a 425/550 and need help deciding on power set up. I have had limited experience and I am old. I practice a lot on a Phoenix sim and I have owned a T-Rex 450 briefly. I found it a bit too fast for what I want. I want to enjoy just hovering and fast forward to the extent of loops, rolls, figure eights. So I want a set up that will be low head speed and pitch curves that will allow just that type of flying. I never will get into 3D. I am considering a Z20A-980, Gaui 60A spd. control, Gyro- Gu-210, and all servos JR DS821. Any and all comments on these will be most welcome. Also, should I use 500mm woodies with stock grips? What is a better choice here. Should I consider CNC grips right off?
I believe that you can see that I am looking for a rather tame bird, but not exactly a fixed pitch type of flight. I am old but am able to fly quite well on the sim. I am an experienced rc airplane pilot and do quite well. I know that doesn't have much relationship to helis but I just mean that I am not a fumbling old cripple, at least not yet. So please help me make these decisions. Thank you so much for considering spending the time to do this....Rich

Thank you so much for considering spending the time to do this....Rich For the most part, your choices look great to me. I don't know anything about the Gaui gyro, so that is my only reservation. You may want to consider the Gaui BEC as well and run a receiver pack. I don't run a receiver pack, but I do have a BEC in my Castle ICE 75 ESC. The advantage to using a receiver pack and BEC is this--and with your plane experience you probably know this already: If you have an ESC failure or flight battery failure, you'll still have control via the receiver pack. The stock grips with the 500mm woodies will do you just fine. Just don't go above 2000rpm headspeed and you'll be fine. Good luck! I'm looking forward to hearing your progress! Scott |

Welcome Rich. Not sure how old, "old" is, but I am in my early 50's and enjoy flying helicopters.
First off, what kit are you going to buy, a 425 or a 550 kit? Both are very similar except that the 550 kit has a longer tail boom, belt, control rod, and larger tail blades and flybar paddles.
A 425 kit can be purchased for about $75 USD, then add the longer tail conversion kit for less than $20, and some tail blades and paddles.
There are lots of gearing options available to get the head speed you want too. I have not used the GU-210 gyro, but it should be fine for sport flying. I am using the DS821's myself on both my 425 and my 550 for the cyclic's and they work very well, but I would suggest a faster servo for the tail. I am using JR tail servos, but many people have been using the Hyperion Atlas DS 20 GMD with great success and it is much less expensive than other tail servos.
I agree with Scott that the stock grips and wood blades should be fine as long as you keep the head speed no higher than 2000rpm. My only other suggestion would be to add the CNC anti-rotation bracket as I just don't trust the plastic elevator arm to keep the swash plate from turning.
Good luck with the build, and keep us posted.
Jerry

Thanks guys for the input. (I am 77 yrs. young) Some thoughts now are about the speed control and keeping the HS down under 2K. I have just read about the Hobby Wing 60A speed control, and although very cheap it sounds good. It has a 5A BEC output and that is as good as it gets for a built-in. $ 54.
I am planning on buying a 425 kit and stretching it. The prices you quoted a below what I have found and would like to have your source. Heeding your warnings, I will buy the Rotor Upgrade Pack so as to eliminate some problems with grips and elevator arm. So, I read that you feel that even for my intended light sport flying I should consider a faster tail servo. OK, I will do that.
Although I don't have a whole lot of spendable income I have long ago learned how to waste money by buying cheap quality. Therefore I am open to paying more for components if I really feel that the cheaper ones may be short lived and have to be replaced. "Buy cheap.....buy twice".
Please keep the suggestions coming.......Thanxxx Rich

Rich, to my knowledge, the performance upgrade package does not include the CNC anti-rotation bracket. I am still using the stock plastic head on my 550 running 550mm blades and haven't had any problems yet. My head speed is around 1900. I do use the CNC head block and grips on my 425 due to the fact that I am running a head speed of around 3000 on it. Hobby Lobby did have the 425 kits on sale for $67 but they are out of stock now. AlleRC has them in stock for $79.99 though. www.allerc.com/product_info.php?cPath=25&products_id=5017There are 3 different tail booms and belts available for running 425, 500, or 550mm blades. AlleRC has all of them in stock. www.allerc.com/product_info.php?cPath=24_118_119&products_id=5022www.allerc.com/product_info.php?cPath=24_118_119&products_id=5023If you do decide that you want the head upgrade kit, this is the cheapest I have found them; grandrc.com/inc/sdetail/133326As for the tail servo, you can use the DS821 if you want to, but a faster servo will give you better tail control, that's all. Hope this post and links come out OK, as the wife is using the "better" computer at the moment and I am using the old back-up that is a 10 year old Dell. Took me dang near an hour just to put the links up there with this thing.  Always glad to help though, in any way I can. Jerry |

Jerry, I really appreciate all the effort put in on this. It is of great help. I found the Rotor Upgrade Pack on Flying Hobby's site and the photo of the pack shows the CNC anti rotation bracket. $ 75 for what appears to be a very complete package.
A member of the local Heli club has just offered me a stock motor from his 425 kit, which he pulled out of his to upgrade when he stretched to 550. I wonder if I should take that and put it in the 425 kit and use it that way, get some stick time on it, etc., before I go to 550. Even if I did I would get a decent tail servo and 60A spd. control so that I would not be caught short later. A plan ?
Thanks again Jerry!........Rich

Rich, I think I know which head upgrade kit you are talking about now, as there are a couple of them. I think that one sells for $99 at most U.S suppliers.
As far as the motor goes, you will need to find out the kv rating which will tell you the rpm per volt. The 425 blades need a lot higher head speed than the 500 or 550 blades. For mild sport flying, you should be able to use a higher kv motor with the "stretched" kit as long as you gear it down to a head speed of around 1900 to 2000. It may 'bog' a little on hard collective inputs, but again, for just mild sport flying it should work ok.
If you want more power some day down the road, you could always change the motor then. I have both a 425 and a 550 and I can tell you that there is a huge difference in the way they fly. The 550 is very stable and easy to fly, and the 425 is much more nimble and can get away from you faster, but is a lot of fun to fly.
Let us know the motor kv and we can help you choose the gearing for whatever blades you are going to run.
