Hi everybody,
I'm just finalizing my equipment list for a new 500 3d - can't wait, it's been a long time coming!
Before I go ahead and order, I was wondering if anybody had any comments, particularly on a couple of items I'm not sure on. Here's what I am intending to order;
Logo 500 3d
Tango 45-10
6s 5000Mah batts
Hercules 5A BEC
Fut 611/9256
MAH 555mm blades
CHP metal motor mount
My question items are;
1. Jazz 55-10-32 or CC HV110 - the Jazz sounds really nice with really slow start etc, but is the 55-10-32 big enough to ensure enough headroom?
2. 21t pinion gives target hs of 1980 allowing for 10% inneficiency, dialed down to about 1800 (90%), but this assumes 3.7V per cell, is that too high under load, so should I maybe go 22t to allow for a bit of voltage drop? I guess I want a hs around 1800 to start off with.
3. Are stock tail blades OK with the 555 mains, or if not, what do I need?
I had a nitro heli about 20 years ago, and never got far past hovering. I have flown electric planks for the last few years, and for about the last year have been flying helis on the sim. So I guess my flying style/ ability will be beginner and hopefully ascending to sport flyer within a reasonably short period (fingers crossed!)
Thanks for your help,
Ant

The 55 esc will be fine, if you plan on staying 6S however I feel the 80-6-18 is a much better choice as it is rated for higher amps and will stay abit cooler. However acording to your desired HS I would certainly say the 55-10-32 will do fine. I have one of my 500s on the 55 and it takes a beating without hiccup. Are you staying 6S or do you have future thoughts of going higher??? If 6S and you have choice now than go 80-6-18, based on where you live Icare in eastern canada will have best price on that esc.
Now that being said the 21 tooth will be fine for your desired HS, however that tango will not be in sweet spot for power of course till you run up to a 22, honestly I would run a 22 tooth with that setup and just dial back the governor % to desired HS, run your idle 1 at say 1800 rpm, and your idle 2 at 2000+ for when you want to rock it out. Or if you really just want a longer flight and some sport flying than certainly go with the 21 tooth and run your % higher. The Jazz does not care if it runs at 60% on the esc it will not show negative results that way. You can safely run 92mm tr blades with 550mm, If you run 555s you are getting close that is for sure. Run 90mm mah or some 85s to be safe if you must run 555 mains and want cf, however,,,, the stock tail blades work 100% fine and are actually 85mm. :D Hope that answers your question clearly enough, have fun you will love the heli.

This covers a lot of the questions I have also.I am a rookie,just starting to transition from hovering to FF.I had planned to use 6s 3700, 45-10,but was unsure about the ESC.that is,80-6-18 or 55-10-32.I have not ordered any electronics yet but the L10 carbon,alum motor mount and 515s are on the way.My biggest concern is temp. with this set-up,as I said I am still just learning FF.I have read the archives several times for a good power set-up and now it seems I was mistaken in my initial conclusion that a 18 or 19 tooth would be the pinion for a target of 1800 to 1900 with 515s.So which pinion(s) do you recommend for the 515s? still go with the 21-22?By the way,I read all your posts and regard your opinion highly.

well 45-10 than 21 tooth than for sport flying or mild 3D yes. Get a 22 tooth for when you are ready for more. One thing I can tell you all is there is a "huge" difference in this heli when you go from 500mm main blades to 550mm main blades. Of course your consumption comes up greatly and I then recommend 4500+mah lipos for running 550s to get good run time. 500s are fine, just do not expect it to pop around all over the place with them is all. As well 500s will be to small when you run bigger lipos and it throws off the power to weight ratio a fair bit you will then need the bigger disc.

Thanks for the reply Shawn,
As for future voltage, I don't really know. If the 6s setup is plenty of power for me for the life of this machine, I guess I won't go up. However, if I outgrow 6S I would probably go to 8s or 10s. I don't know how this will go until I get flying it. Do you have any thoughts on this? ie. am I likely to want to upgrade the voltage after a while when I start pushing it harder?
When you say you are running a 55 on a 500, I presume that is on 8s or 10s, which means less current draw? Or are you running on 6s with no problems? Because if you can fly hard on 6s and 550's and be fine, I will probably never load it up that much?!
BTW, I did see another thread of yours where you appeared to have attached a heatsink to a Jazz - is this just a computer store heatsink attached to the outside of the heatshrink, or did you pull the covering off? What sort of glue did you use? Is this a good idea for me?
Thanks very much for your detailed reply,

On the 55 I am running the 6S actually, no issue. However it never gets real hot here in the north, so would I recommend it.... not if it gets hot where you live or unless you plan on running bigger voltage down the road. As far as voltage goes I recently tried 8S, went like a rocket, only the higher voltage smaller cells do taper off abit quicker, more power but the avg power might be equal on 6S, and flights on a 6S 5000 pack are longer to. Heatsink,,,,, yes that is just a pc type heatsink I cut up, I put them on all my Jazz escs, not that they "really" need them however the cooler any electronic device on the heli can run the better, cooler=more power and I am all about maximizing the power on my E machines. I use the thermal epoxy to adhese them, you can buy this at any computer store. Alot of your questions can only be answered if I knew what you were going to do with this machine in future and what style of flying you truly do, I have answered best I can based on what you have said, hope that helps abit, if not let me know. :thumbup:

Thanks again Shawn,
Sorry about all the questions - it's just that I find it so difficult to decide when there is no 'obvious' esc to choose. One reason it is not obvious is, as I mentioned in the first post, this is essentially my first heli. So I don't know how long it will last (a while I hope!), and how good I will get during it's lifetime. So there is a lot of hypothesis going on here. At the moment I do sport aerobatics and light 3d on the sim, but there is a big difference between doing it on the sim and in real life I bet. It doesn't hurt when you crash the sim :) But this is the type of flying I will aim for in time.
Anyway, thanks for all the great information you have given me, it really helps. At this stage I think I might lean towards the Jazz 80-6-18. I get the feeling that 6s will be plenty of grunt for a while yet.
Thanks,
Ant
Iam kind of wondering why you are using 5000mah and not the typical 3700mah. What kind of flight times are you expecting and will the extra weight be noticeable ?

I have been told and have read on this site that the 3700's are suited to 500mm blades, and the 5000's are better suited to 550 blades.
This is due to the larger rotor disc therefore the 550's can handle more weight and also need a bit more capacity as they consume it faster.

Exactly whta Ausant said, bigger disc bigger battery. The larger disc gives a "ton" of more pop. If you are in the learner to sport flying stage the 3700-4000mah range is fine as are the 500mm mains.
