Ive searched this forum in vain trying to find a link to this video, the best I could do is find a link to a page its on.

http://www.liorzahavi.com/videos/other/

Its the vid named.
Lior Zahavi HDX500SE Mar08.wmv about 3/4 down the page.
Im interested about what anyone whos seen this vid thinks about its credibility, if you havent seen it its worth downloading, pretty hard 3d and shows how powerful one of these hdx 500`s can be.
At the beggining of the vid it claims to be kitted out with the following.
Medusa Research MR-036-050-810-5 brushless a Pheonix 60 amp running an Outrage 4s 3700 25c.
Im running a 1050 kv 75 amp speedy, flightpower 4s, my hdx used to be pretty powerful, but know where even close to this guys.
Is anyone out there getting this kind of performance on a 4S.
((Notice the consecutive hard climbouts with absolutely no bogging, and the motor doesent even seem to be trying, at what I would roughly guess to be at least 12 degrees of pitch or maybe more.))
On a 4s pack?, this is not a gripe on my part of any kind, im just very interested to know if my heli is badly under performing, everything is now new except the speedy, if you guys come pack and tell me this kind of performance is normal, ill go buy a new speedy tommorow, I just think he has to be running a 5 or 6s, and if thats the case its a very misleading video for anyone whos looking to buy a 500 size heli, dont get me wrong I love my HDX, please anyone reply would greatly appreciate how there hdx 500`s perform reletive to this video.

I think ive figured it out, was just checking out the guy`s website flying in this vid, and what do you know, he`s sponsered by helidirect, I would put money on it that its a 6S pack inside that heli.

I would say that yes that could be 4s, I don't know the specs on the medusa motor, but I tried a RCP H/18 1100kv motor which had very similiar performance on 4s Evo 3700's, crazy power and headspeed, but short flights, I now am running a scorpion 1000kv with just slightly less performance and about 5 minute flights, but now have it geared for A123 cells and I get around 4 minutes. in the vid you can hear the motor bogg, but he has very good collective Mgt!

i think you'll find he's not sponsored by Helidirect any longer.

Please cancel my clearance, I have the field in sight. Got my RW Turbine Waiver, need lottery!

wonder my one dont fly like that
4s 25c 3700 flightpower, zpower z20a 980kv, align 75 amp speedy.
only 10 deg up and 9 deg down. everythings new except the speedy, Im gonne have to get the courage to tinker with the speed controller settings to check the timing, e.t.c, ( there dont seem to be a smiley face for paranoid. )

The only thing thats on my heli is I cut down a couple of 30 size tail boom supports and used em instead of the thinner ones, but the weight difference is minimal, proby as much weight as the straps holding the pack in.

that Z20 is a nice motor, but you will need more the 980kv to get that kind of performance. i am now running the scorpion 1000kv,and on 4s it is nice but not a power house, on 6s A123 it is better. but the RCP H/18 was a rocket!I know the H/18 is under rated though at 1100kv, huge difference between it and the scorpion 1000kv

so I guess I just wasted 100 dollars on this new 980kv motor.
I never seem to learn. will be grabbing a trex 600e hopefuly this week, hopefuly that will be a bit more successful, can anyone tell me if I will get simmilar power with a 6s 5000 than what I used to get with my 50 hyper nitro?.

Wouldnt it be easiest to ask me personally ?

Well this was shot using a 4S 3700Mah pack indeed, want pics to prove it ?
Since then i went to ThunderPower packs, also on 4S, just slightly larger capacity at 3850Mah. Pack is not even warm after a flight.
Its not the strongest heli i have ever flown, but it flys really well !

I never flew the 500 on 5S pack.

And yes, im sponsored by HeliDirect. i have no idea why Hotwings posted what he did.

Lior Zahavi is one of our first sponsored pilots and he is flying for all of our HDX helicopters.

He used OUTRAGE XP 4s lipo on this video.

If you have any questions you can contact us.

thanks for replying,

can I get your specs and gearing also flight time! what is the kv on that motor? I am probalby going back to the RCP H/18 in my HDX, I haven't been real happy with the stock 890 or the Scorpion 1000kv. the scorpion does pretty good but just doesn't hold rpm well, and the h/18 was a rocket but lower flight times. I had hoped to go A123's but i may stick with 4s 3700mah as well.

edit, i just checked the medusa, so it must be the 810kv? seems really low? really curious as the gearing

I'll add some info on Outrage packs!!

Hi,

No one here knows me, and rightfully so, I'm no hotshot 3D pilot, and no one sponsers me and my fleet of heli's. All bought with hard earned cash, and I'll shoot down anything if it's garbage and has cost me that hard earned cash and offered nothing in return.
So, let's see what we have here. The following batteries, all used in 450 size machines, since all of my larger heli's are glow.

-2 Flight power 2150mah packs 3S 25C
-2 Outrage 2200mah packs 3S 25C (1 used, bought with 23 cycles, the other brand new)
-2 Thunder Power V2 2200mah packs 3S 25C
Align 35 amp ESC
Neu 1105Y motors on both machines (3DX 450/E325 Mini Titan)

I've found consistently that the Outrage packs are almost always perfectly in between flight times and power supply of the Thunder Power, and the Flight power in that order.
I can squeeze 8-1/2 minutes (sport flying) out of the Thunder Powers, about 8-1/2 to 8 minutes out of the Outrages (Keep in mind, even the used one is able to do this), and about 7-1/2 minutes out of the Flight power's. The Outrage packs seem to keep the power curve loss more gradual though. Where the Thunder and Flight powers seem to suddenly drop, and so do my heli's, the Outrage packs seem to just drop enought that my ESC will slow down the head only slightly, and I can "feel", if that's an accurate term, that my power is dropping. The Thunder's just suddenly hit their wall, and my ESC suddenly drops the power abruptly, and my heli plummets for 8-12 inches, if I were near the ground, it would be a fairly hard hit, but most of flying is 6-10 feet up, so no big deal, and you are certainly made aware of what's happening. The Flight power does exactly the same thing, just loses it's abilty to keep a solid hover, and the heli drops. Once again, I'm high enough no big deal.
Now, If I decide to go inverted and cut grass, there's only two packs I'll use, you got it, my Outrages. I just like these batteries. As soon as I have a little more of that hard earned cash, I'll be picking up two more Outrage packs. (I hate having to recharge...

Just spent heaps of money on 6s packs and a trex 600.
Flies like a bag of ****, can hardly even fly it, and its even more gutless than my hdx 500, the tail is wagging all over the place due to the slow headspeed even with t curves flat 100 percent.
I dunno where to go from here, start replaceing every component to find whats wrong.
**** this **** is all I can say.

I am a bit calmed down now after soaking in the realisation that my new heli is crap.
It looks though ill be going back to my Hdx in light of my current situation, and trying to get it to run something even close to that in the vid, dont get it though because 810 kv is even less than my z power that is 980
It is going to take me some time to come to terms with how much money ive just parted with and all for nothing.

I have come to the conclusion their is a lot more to a motor then just the kv!the watts means a lot as well. I tried a scorpion 1000kv and it was terrible! the stock 850kv flies so much better! if you have the Z20 and a bunch of 6s packs I would try gearing it for 6s! right now I am flying my stock motor on 6s A123 and performance is very good! 4s it flies nice for a sport flier and cruising around but it's really a dog! on 6s A123 the motor is a little warmer then I would like so I may try gearing for 6s lipo I just hate going back to lipo!

Im really interested in these 123 cells, specially now im reading that im only likely to get 20 cycles out of my 6s packs before they start to die away, what is the go with speed controller and motor?? do you need a different speed controller??
I need to find info on anyone whos done it with a trex 600 and hdx 500.
Im looking there that i3dm heli in the vid is 24 tooth, im sure I was useing 19 or 20 for 980kv, maybe this could explain the higher headspeed, it really screams where my hdx has a really low sounding hum.

I think the reason my heli wasent performing well was because all the settings on my align esc was se1 to 1, that means low timing, brake on, airplane mode... you get the picture.
Since learned how to set it up on my trex 600.
Only problem now is the tail is constantly drifting to the right and ive tried everything I can think of.
Anyhow if I can get the tail sorted I think its going to fly alot different, seems to be pulling up in a climb the way I would of expected it too.
