I took the plunge today

[billyd]

Bought the Logo 500 3d Flybarless.

Man that got expensive quick. Yikes.

Ordered the Orbit 25-8 motor with a 14t and a 15t pinion (.7 mod). Jazz 80 esc, 550mm rotortech main blades. 8717's on the swash and an 8900G on the tail. CC 10amp bec. Using my 6s batteries from my 600e.

I think it's going to be ridiculous. :banana

[Mathias]

You won't regret!

That's a nice setup for sure, man!

Very close to my own, but I haven't got a V-Bar and I'm running the Spartan on the tail and the RotorTech 560s.

[Mercuriell]

:thumbup: - Looks great - any particular reason for goingt with the Orbit motor ? - I'm finding my Hacker 40 10L a bit limited in the power dept and was wondering about trying another motor

[billyd]

It came highly recommended by another freak and after researching it everything I've read says that it's top notch. Super efficient, super long flight times and gobs of power.

It's hard to find in the US I had to buy mine from a Canadian site.

http://www.rcflightstore.com/product_info.php?manufacturers_id=34&products_id=1207

They also had the pinions I needed, which are also very tough to find in stock.

Wow I didn't know you could go to 560mm on the 500 ! The Spartan gyro is awesome.

Nice thing about the flybarless is the gyro is built in, so at least I didn't have to buy that too! lol it was plenty expensive though.

Major pucker factor with this Logo (Alot of $$$$$ in the air yikes :wow2:) so I won't do any hard stuff until I have it down on my 600e first. LOL I never thought my 600e would be expendible, but the parts are easier to get and cheaper.

Where's the best place to get Logo parts? I've noticed they're pretty scarce!

[Big Fil]

Congrats Billy, your going to fall in love with the thing. As a Trex600E owner as well I promise you this. I actually thought as you do that i'd baby the logo cuz it's more $$ to setup and fix, but it flies so well it is confidence inspiring. There are things I do with the logo now that I actually worry about doing on my 600E or 450.

Try these places in the US if you need parts.

Modefo's
Esprit Model
FXAeromodel

RCflightstore is great but shipping to the states hurts. That's where I got my 560s from when nobody else had them although I ended up paying more for them with shipping than a set of 600 V's.

Thanks Big Fil. I am fired up for the Logo. I appreciate the tips on suppliers.

Yes the shipping from Canada was $25 and it's going to take 5 business days to get it, but I couldn't find the Orbit in stock anywhere else. But the motor and two pinions was over $320 so the $25 wasn't too big a percentage hit. It would be hard to buy a $15 part from them though :YeaBaby:.

[Big Fil]

That orbit is supposed to be nasty powerful! I was going to go with it until things started adding up so I went with the Hacker 8L. If and when that motor doesn't do it for me I may upgrade to the orbit.

Anyway just took some new pics yesterday and seeing as our setups are close figured you might like to see these.

[LITHIUMSTATIC]

Oh yeah... :YeaBaby:

[stvjeep]

I guess the Orbit motors are more for power rather then flight time? Which motors are best for flight time in the Logo 500?

[LITHIUMSTATIC]

My guess would be a Tango 45-10

[doeni]

I would cancel the order, V-Bar just reduced from 700€ to 399€ in Germany, Mikado will for sure change the prices in the US soon too. So i'd w8 a month, even though it is hard

greetings Daniel

If you are going to run 8717s be very aware they pull pretty big amps, I would opt for a 2S 1345mah FP rx lipo and a Spektrum Dual Voltage regulator. That way your Cyclics (8717s) are on 8.4 volts and your tail will be stepped down to 5.2 and you will not have to worry about failure due to the draws,, just a thought.

That's what I have the CC bec for, it has a programmable output voltage from 4.8-9 volts and I will be using it as a voltage regulator with a seperate lipo.

I wasn't planning on 8.4 volts to the cyclic servos though. I was going to run them at 6 volts and then step it down to 4.8v to the tail. I'm not sure what the v-bar stuff runs at though probably 4.8v also is my guess.

The 8717's are so fast at 6v, it's hard to believe a human could detect a difference at 8.4 v. Plus nothing is rated that high (at least per the documentation), so I would be concerned about failures.

[OICU812]

FWIW.. I do know that is why you have the BEC. I know of a few cases where the CC BEC has failed, this is why I am stating the amp draw and reliability factor is all. For clarification the Vstabi equipment is good to 9.0 volts, as are the JR 8717 servos, this I know for 100% fact :D. Most tr servos are good to 5.5 volts, 4.8 volts was Futabas old terminology when dealing with 4 cell NIMH packs, many get confused of this but 4.8 in the NIMH and Nicad world is equal to 5.5 in the lipo "regulated" power world. Also in conclusion I can assure you 100% I noticed a "massive" difference in cyclic response between 6 volts and 8.4, the difference is huge. My thought is if the servos are designed for it "which they are" I would think it is best to take full advanatge of their abilities, at least this is my thinking. Enjoy your heli, cheers :)

Thanks for the great info. The CC Bec is 10 amp. Are you saying the servos will draw more than that or that the CC bec is unreliable?

I will go ahead and run them at 8.4 volts then! So the tail is ok at 5.2 and the cyclic and all electronics can be run at 8.4v. How about the receivers are they all ok at 8.4v? I am not sure which one I will use yet.

The CC BEC is rated for a burst of 10A but 5A continuous for V>24. I run the CC BEC with my BLS451 @ 6V (150 oz-in) but my servos do not draw the same current as the JR8717s. There are also stories on the forum of others trying the CC BEC with your type servos and burning them up due to BEC failure but I think that was a V1 model of the CC BEC and the newer ones (since Oct 07) seem to be fine. As Shawn mentioned you might want to look at running a 2S lipo or using a WR 5A BEC. Its just that the JR8717s seem to be overkill on power needs.

And yes, the Spektrum RXs will be fine at 8.4V but not older PCM.

My $0.02,
Bruce

[billyd]

Thanks Bruce.

How about the futaba 2.4 ghz receivers can they handle 8.4v?

ps The CC BEC is actually 7 amps continuous with a two cell lipo as input. It drops to 5 amps continuous for a 3 cell lipo and up. I would be using it as a regulator on a 2 cell receiver lipo.

I did a quick check and it looks like Futaba FASST only supports 4.8-6V but maybe someone else can check on that and report back.

If you use the CC BEC (@ 6V) as a regulator from 2S -> RX and a step-down for the tail servo you should be good based on the CC specs. One thing to note is that if you use it as a power regulator into the RX, you should remove the signal wire from the BEC. CC uses that for programming the voltage with their USB interface but there were problems with that interfering with Spektrum receivers when plugging into the battery channel because of conflicts with the binding plug.

[Finless]

Yes the SPektrum RX's can run at 8V.
This is the hot setup now.
RX run at 8V and the 8717's run at 8V. You then use a regulator on the gyro. No need to run the gyro at 6V and have a step down to the tail servo. Just run the gyro at 5.2 and it powers the tail servo.

Dude... your gonna love that setup man..

Hey billyd,

just in case you haven't seen it check out this page on CC website

Even the BEC's 7amp rating might be cutting it close if you take into account the tail servo as well.

I think he hinted that he is using Futaba FASST which looks like its only rated to 6V.

[billyd]

Well I don't have a spektrum radio. I've got some hitecs and a some futabas and an airtronic laying around somewhere..

I was planning on using the Futaba 9chp with the TM-8 Module and a 7 or 8 channel 2.4 ghz receiver... that's the setup I have on the 600e.

I bet the Futaba 2.4ghz rx will handle the 8.4 volts even though it's not documented. It's probably better to run it at the higher voltage which will reduce the throughput amperage anyway (at least that's what my one semester of electrical engineering tells me). At any rate I would either have to buy a Spektrum radio or buy a spektrum module for the futaba, and an rx (which would end up costing almost the same or more, why do these radio guys like to torture us?) and I don't want to do that right now. I am up to my elbows in radios as it is.

Worse case I trash a $100 rx, which is a little more attractive than blowing another $400+ on another radio. Hey I've been running Futaba servos at 6v forever and they are fine even though there are warnings all over the futaba docs not to do it.

Somebody stop me if they know the Futaba 2.4 Rx will fry at 8.4v, I am at least a week and a half away from flying. I don't even have the first piece of hardware yet.

Wow those 8717's are hungry beasts then ! Well I looked at the spektrum dual output regulator but the only one I saw (at readyheli) said 3 amps continuous so that can't be the right one. Anyone have a link to the recommended bec/vr for say 10 amps continuous on this setup?

Anyway I am toying around with buying a DX7 but man I have so many radios it's hard to pull the trigger. One of these days I will get off of my a$$ and get all this cr*p that I don't need on Ebay :arggg:
