Hi everyone,

First would like to say this looks like a great forum to be apart of where everyone is friendly and willing to lend a helping hand, so this leads me to my first.....

I have been flying electric helis for a little while but wanted something a bit simpler and more stable as I am venturing into FPV/videoagraphy. It is what i originally hoped to do with the heli but was a blown away with what can be achieved with a quad etc with what I think is a better result.

I was thinking of getting the DJI naza kit. I liked it for the simplicity and what the flight controller had to offer with the altitude hold. But since doing some reading, the flex is in frames possibly causes camera and FPV vibration (did these people have the rpops balanced?). So I thought the VC 450 frame (plus the additional plates) from hover things looked like the goods and using the naza controller with some Graupner props but his is now where the confusion starts for me.

The manual for Naza says the ESC's need to have a refresh frequency of 400hz, are most esc's rated at this and how to I find out that?

Motor selection is the big one. I don't understand the desription of the motors like TR35-30C-1100 except that may be the last numbers is the kv? Most of all what kv should I be looking for?

The Naza kit is a close ball park figure what I looking to spend also.

All suggestions, opinions and experiances will be taken on board so I thank you all in advance and please feel free to post any photos you want to add

Ben.

Turnigy Plush handle 400 perfectly... Maybe also wait for the new FPV frame that Hoverthings should be releasing this month... look for the thread in this forum VC-FPV1
me and Juz run 1200 kv motors with 8 or 10" props... Lower KV larger props for lifting capacity ... The Avroto motors as a real power house can run 12 - 14" props on them

I too have the VC450 and have a Naza installed for a buddy that wants to get into Quads as well..He ask me to test the Naza for him because our Beloved CC boards are not available for the time being.

I'll post photos:











Setup:

VC450 frame
4 RC timer 2830 -14 750 KV
4 DYS 30A ESC programmed to SimonK firmware
GWS 10" 4.5 props
6000 mAh 4s Lipo
GoPro 2
WDS 690 TVL pilot FPV camera
Dragon Link UHF
Eagle Tree everything...OSD Pro, Guardian, E logger, GPS module
Turnigy 9x with Smartiparts and Er9x firmware

Naza flys...IMHO opinion..the Only thing it has over the CC Board is the Battery/Failsafe Auto Land and the Altitude hold....but it still drifts in the wind
there are only basic tuning features and no PID tuning.


Total AUW 4.5 lbs

Here is my last flight with Naza Mounted.  If you look closely you can see the pitch twitching in the 10 mph wind..this was at de-tuned pitch gain of 40%

Flight time outta that setup ? and what stick % is lift off ?

7.5 minute Flights  45 - 50% liftoff

[snafu]

Thats awesome flight time with like 2.2 Kilos of weight..

Yep..its also one big friggin battery too!   She's heavy...but she flys...I'll be putting my CC board back on this weekend

So are the motors you running any good? Quality, performance wise that is.

What are their esc's like (and will they work with the naza) because there are no turnigy plush instock from HK.

Would I be best going for the 750kv or 1000kv motor?

Once again I will not be doing any stunts but will be chasing around 10min or more if possible on a 3s pack, or will 4s be the go?

The photos are great, thanks.

Lots of people here like to run their potential setups through ecalc. I've used it to get an idea of what kind of flight times to expect with different motors.

The DYS, HobbyWing, RCTimer ESC are pretty much the same as the Turnigy Plush. I run RCTimer 30A esc on most of my setups. What are you planning on carrying with your quad? I also run those same motors and for the money they, are very good. My only complaint is that the prop adapter alloy is soft and I have deformed a few on crashes.

Depending on weight you could possibly run greater than 10min on 3s. I have gotten around 10min (mostly hovering) with 3s 4000mah with those RCTimer motors swinging 12x4.5 props. If memory serves me correctly, my quad weight at the time was around 1.5kg. That might have been pushing the motors pretty hard. Personally, I would consider 4s for a quad weighing greater than 1.5kg.

And you can't go wrong with a hoverthings frame. Their frames seem to be the choice among CopterControl FPV Pilots here.

Im using Rustys frame, the UAP1, and the iPower motors from Monto RC2814-11's, same size as the avrotos but cheaper
so far rustys frame is bomb proof except the arms that save everything else from damage, as they crumple, (i do alot of crumpling)
its been great for me in my learning stage, all you need is extra Trex booms,
the motors are smooth and full of power,
im swinging 12x4,5 props and getting 7-9 min on a 2650mah 3S battery,

saving for the 6000mah 4S,,
and someday ill get a hoverthings frame too

[oz500]

I will be just adding all the systems required for FPV with OSD and a GoPro. I have no idea yet what this will all weigh.

As i flick through various threads the CC Flight Controller seems to be the weapon of choice. I am yet to read up about them are they that good?

I recently enquired with hoverthings and I was impressed with the honest and prompt reply. I think they will almost certainly be getting my future buisiness.

oz500, u do know ther are better boards out there, these guys are to busy blowing there load over something that only stablizes

You know, oz500....there are Other Forums too!....I would recommend you visit RCG...you would probably "fit in" there.  They tend to cater to adolescent immature juveniles

Of course, I'm always up for an Intellectual, logical and informed debate...so let's hear your "better board" soliloquy.  If you are going to make a statement, be prepared to back it up with facts....not innuendo!

You are correct in the fact that the CC board's primary function is to stabilize....you are however, incorrect in, that is it's only ability.

For the price they seem to be good value and the fact that I have not heard one bad report about them may just say something.

Pity there are none in stock anywhere, I would like to give it a go.

Sorry Oz...misdirected post....I ment my comments for Gdub73

[dankers]

I missed this thread, first my apologies to you oz500, this is a real friendly forum but there is always going to be the odd bad apple, sorry you had that welcome.

We tend to let most things go, but I was stunned to see that post from someone using our infrastructure to hate on the project. That would not be tolerated in any other project and I think maybe we are being a bit too easy going. After seeing more of this nonsense today, gdub73 has departed the OP forums, it's just sad we are trying to do something cool and positive yet have to deal with people like that.

If you looks at the Revo thread, you will see why there are only a few boards, it's not something we can control, the gyros we were using had a high failure rate and the new gyros we need can not be bought yet.

[oz500]

Just awsome,

I have got my motors on the way, a set of NTM prop drives 1200kv. The initial problem was that the prop adapter and mounts that have to purchased separately were out of stock but thankfully due to the generosity of a member i have been donated some as a loan till I get to buy some.

Also on its way is a VC 450 frame from hover things. I was going to wait till the new one came out but seeing the amount of interest in them i reckon it will be hard to get in early enough for the frame let alone any spares. Having said that though, I will still try .

I am giving up on the turnigy plush esc just for the availability, so I am thinking of these, which are available in Aust

Will I need the programming card? and I take it these will still work with the NAZA?

Thanks all
