Ready to rumble!

[Finless]

OK after finally getting my packs, clearing my plate of videos, etc I today spent all day updating my Hurricane 550.

So here she is.
All metal bling in the head (except the flybar cage), New FlightPower Evo25 2500ma 6S packs, and my 600+ motor with 14T pinion!

I cant wait to fly her Saturday! I will do a video too :)

Nice one Bob! What motor is that specifically? Nice FP packs, better to use straight off 6s instead of series'ing up 2 3s packs I think. Just less of a hassle :)

New motor mount or stock one?

Is that a 75 align esc with heatsink as well?

We're itchin' for your video…a request - please do some straight shot full pitch vertical climbs from both an upright and inverted hover, want to see how that rocket shoots up!! If you can avoid it, please don't use music, want to hear the blades/headspeed changes…

Cheers!
Shaun

[Finless]

WIll do and I never use music when I am showing a heli for purposes of showing new things.

The motor is from my Swift and is the 600+ (Suppose to be the same as the Z30-1100) and is using the Cnetury 80 amp ESC.

Not sure why you want to see inverted climbs as well but OK....

Bob

[Finless]

Oh and sorry I dont have the new motor mount :(

So I might have to take it easy a little and I have to break in my new packs BUT I still should be able to show some better preformance than the stock setup

Hi,

I tried to install the CNC Washout Arm Assembly as you did, I can see from the picture that you are using the hex screws, I got bad interaction problem wih the ball links and the top of the screw, it is very close in your case also I can see. Don't you get this problem in when the swash in down with some aileron ?

[shauntot]

bob - ah.. i thought your motor was a zpower. would be interesting how that matches up...don't know, just want to see how the heli pushes air inverted...for some reason i can't get it outta my head that inverted climbouts takes more power (not really) but i just have that thinking hehe

well since you don't have the new motor mount, it'll be actually better for us who didn't buy it yet, now we'll now if we really do need it :D

can't wait!!

[quickster47]

Wow Bob, that really looks good and can't wait to see the video and how it now performs.

No they are not hitting for me and I just double checked because of your post! On my swash the upper balls all have a little brass spacer behind them and that moves the ball out. It is close but not hitting.

[Azzurra]

Hi Bob,

why did you mount the batteries on the lower mount? Isn't it closer do the vertical CG on the upper one?

best

Carsten

[Finless]

With those 6S packs and thier height, the pack had to go so far back so the canopy would go on that the heli was tail heavy. They fit in the lower shelf, canopy fit fine, and the CG was right on.

Later I may mod the frame to get tem at an angle like Tom Viper's heli.

Bob

[AdrianM]

So whats the skinny on the new setup?

[Finless]

Well I got 2 flights in and 1/2 way through the 2nd I stripped the hell out of my 42T gear.

100% throttle head speed was 2340 at 0 pitch. 2210 at hover.
First flight I dropped the HS to 2000 and performance was pretty good but I still wanted more power... 2nd flight I went 100% and really started to tear into the heli when STRIP.... forced auto.... All is OK though.

Here is a little vid showing the issue
http://video.helifreak.com/?subpath=finless/hurricane550&filename=hurricanegear.wmv

So looks like I will need to get that new motor mount BUT Adrian I think we really need that cnc harder first gear. Even with the new motor mount I cant see that thing lasting in its current plastic makeup....

Also while 2200 hs was good I think I will want even a little more.... The 600+ motor was pretty warm. Batts and ESC was good but the motor was about 160 after throwing a lot at the heli. The reason I think is the load up. It didnt get this hot on my Swift and this is a lighter heli.
I am now thinking that with the metal grips and head we should be able to run 2500.. On my Lepton I run 2900 and 2500 on the Hurricane with 500mm blades should be the sweet spot for hard core ;)

So with yuour new 68T gear I think these pinions will be the area to work with
23 9.49 - about 2300
24 9.10 - about 2400
26 8.40 - about 2500 :)


I cant wait to try them!!!!! Get moving man ;)

Bob

[AdrianM]

I agree about the stock gears. I took one and snapped it in half to see the structure of the plastic. It has a high fiber content, which is good, but it has a lot of voids (air pockets) in it. The CNC gear will be stronger.

The motor mount has eliminated most stripping problems for the guys that have it and in combination with the motor moutn should fit the problem.

I am a bit worried about the main gear now. I will get that one cnc'd too.

I will send you a test 1st reduction gear this week when I get it. Don't run it with out the new motor mount though or I am sure the same thing will happen.

[Finless]

I just contacted subtrim to order the new motor mount. I wont run the gear without it!

Also I have your early .6 mod pre produuction pinions (24 and 26) and the production 23T is on my lepton.
Can I get the production 23,24,25,26 as well?
If need be I can buy them. Let me know.

When I am done you will get the straight skiiny on which pinion works the best with the Z30-1100

I do also want to try the Trex 600L motor (A lot of people PM me asking about that) later as that might make a good alternative. It will also help balance the heli for folks running 2x3S packs. I havent calculated the pinion for that yet.

Thanks!!!!

Bob

[AdrianM]

Bob - I make the .6M pinions from 18-23 and Hirobo makes a 24 and a 26. I stopped at 23 based on your advise :wink: I will get you a full range of RevCo pinion to go with the reduction gear.

I recall that the 600L is a 1620kv motor. With 6S batts you would need to run the 61T main shaft gear as the first reduction gear and the stock 14T .8M pinion. This will get you just over 2500rpm.

I have heard that the 600L is in reallity more like a 1900kv motor. In that case it may be really good as a 4S or 5S motor with 3300mah batts.

[Jaso]

So your saying with two 2s 3300 mah packs strapped up front on std batt mount to make a 4s pack, the 600L would be a good set-up ? And the claimed 1620kv really being around 1900kv you could run a 15 or 16T pinion to get around the right HS ?
I wonder what this would do for amp draw as running the lower voltage will push up amp draw ? Might end up back to square one with amp draw being marginal for the 3300 mah packs , same as running 6s with two small capacity say 2100 or 2200mah packs ?

Just throwing around ideas ?

I like the idea of two 2s packs at 3300 mah to get 4s 3300mah because these size pack are pretty cheap .

Jason.

[Finless]

and Hirobo makes a 24 and a 26


Yea but that was for the Lepton which comes with 24 and 26.... You might need them now for this heli :)

But in the mean time I will test witht he Hirobo pinions if 23T isnt cutting it.

My new motor mount is on the way from Broke-again (Subtrim.com) so I will be ready to test! I cant wait actually because the short flight I got before stripping the gear was FUN.... I knew this heli had a lot of potential and I got a taist Saturday :mrgreen:

Bob

[quickster47]

So I might have to take it easy a little and I have to break in my new packs.

Bob,

You mentioned breaking in your packs. Is there a proper way to do that with lipo packs?

Carl

[Finless]

I run 4-5 flights of about 3 minutes (this time depends ont he heli, amp draw, and pack size) with basic flying. The idea is to only discharge 50% of the pack and not do HIGH amp loads. After 4-5 of those they are ready to go!

Bob

[Tom Viper]

I think you need better gears, even if you are using the new motor mount.
The gears last alot longer, but they will strip´eventfully. Tic/Tocs are the killer manouver, everything else works great.

How is the progress with the cnc gears? I cancelled my order when the new motor mount came. And we made alot of succesfull flights with it, but then suddenly, Mr Strip appeared again... Shame, shame on you Mr Strip!

If the gears are comming out soon, I want to place an order for these!
Starting with about 20 pcs...

About blades, the MS 515 carbons really make this heli rock!
Togehter with the Raptor 50 flybar (stock paddles) I cant imagine anyone want more cyclic speed!

As you may know, I have tried out the Align 75A esc, but after getting alot less power, low HS and a very hot motor this is going away! We have flown and compared two identical hurricanes, same motor and packs, but one with the stock Gaui ESC, and mine with the Align one, you can really notice the diffrence. I guess the Align esc don´t like the Z-power motors? Oh, yes, i HAVE tried all the diffrent timing options. I am now giving up on it and will replace it with the stock or the new 75A Gaui esc. Strange how the ESC can make such a big diffrence! I just cant believe it myself!

[dutch_anykey]

Hi Bob,

Any chance that you wil be testing new setups in the upcoming weekend?
I'm really curious about your findings. I need to give my hurricane more power. But i'm still not sure where to go.

Cracking my skull over the different configurations
lipo's stay at 2 x 3s or 1x6s
Z20 OR Z30
Esc...


And the worst part....i cant fly right now because my dx7 has the "BACKUP ERROR" fault...so that one is taking a holliday overseas at SpectrumRC's revalidation clinic.... :smokin:

Best regards,
Maurice

[Finless]

Well I am hoping my new motor mount and replacment GAUI gear will arrive today or tomorrow. If not then no.... As Tom Viper said dont expect tge GAUI gears to last to long even with the new mount BUT I should be able to get enough flights top know if this 600+ motor is the ticket or not. I personally think it will and if so I will probably get a REAL Z30 since I hear they are more effecient.

Anyway keeping my figures crossed for parts to show up!

Bob

[AdrianM]

The CNC 68T .6M 1st reduction gears and 61T .8M main gears shipped to me yesterday. They should show up on Monday.

We need to do some testing to make sure they hold up well and that the gear ratios are what we need. As soon as we know they are good (I am pretty sure they will be :wink: ) I can get quantities in ~2 weeks.

Hi,

When using a large first reduction gear there is very little space left between the gear and the servos.. I don´t see how you are going to fit in a large pinion..

I have tried the Gaui large gear as first reduction gear and the maximum pinion size was 15T before hitting the servos (or the chassi, i dont remember which one it was..)

Have you guys been thinking about this?

[Finless]

Well my parts didnt arrive today so no testing this weekend :(
They are probably stuck in Customs :(
