A lot say that tiger axis and Qc are the same motors..!

Good to know.

tiger/QC/avrotos only take 4s. And the AXI's are definitely not made by tiger! They are in a league of their own.

Nah those OEM Tigers as in the QCs take 6s have flown them with it and they are advertised like that http://www.quadrocopter.com/QuadroPower-Motor-QC-3328_p_392.html and so do the torxs http://quadcopters.co.uk/torxpower-3536-pro-heavy-lift-motor-700kv-124-p.asp
axis are certainly not tiger motors. But Torx Qcs are tiger motors and in the case of Qcs totally overpriced.
And i am pretty sure that the motors on the s800 are also a OEM tiger motors version.

benjamine check out the http://www.kopterworx.com/Motor-Servo-and-more/KW8-pro-+-6mm-adapter
I think they were especially designed to get a little more punch on the CS8 than with the normal QCs. No of some guys here in vienna after the plettenberg dilemma that switched to them and are happy with them.
But i ask the copterworxs guys they are behind them.

Test fly with the intended weight and check the temps on everything. Have them get an insurance cover note for the day of the shoot. If **** happens keep your cool and land. Rinse and repeat.
As for the motors. All vendors selling Tiger motors are selling the same stuff. Plain old Tiger motors. The just sell them at 3x the price because the motors are prone for failure and they need their profit margin.
If you are going to spend more than 80 euro on a motor I find it extremely foolish to get anything else but AXI motors.

not all of them are pulling that margin.

and to tell the truth but probably just back luck i have two axi that are messed up, two times ball bearing ruined. Out of the 12 tigers I have since a couple months no problems.

The take 5s with EAsy after a lot of tests..! And if you send an email to rctiger they will tell you that 5s is no problem..1 DOnt stay at the specs only..!

You are absolutely right with the connectors....flying around with equipment for thousands of $$ and not taking care for a proper electrical connection is not very clever. I am also only using EC5's and I am more than happy with them. To avoid "sparking" when connecting the LiPo's there are two ways:
The cheap one:

The more expensive way:

The good thing about it is, you connect the LiPo's without sparking and you arm or disarm the whole system with a magnetic plug/switch. It's just 45 g in weight and is worth every cent....normally it is used in RC planes and helicopters.

Welcome to MultiRotorForums.com!!
how about this? if you have dual batteries, put a switch on one of the positive leads. connect the battery, flip the switch on, then connect the other non-switched battery to its lead which won't spark because power is already on.
you could also put a small 4S (or whatever you're using) in place with a switch to power up the board and then connect your two batteries once power has been supplied. switch off the small battery before flight and it will last almost forever.
just a couple of quick thoughts that came to mind while reading.

I really appareciated this information. When I first started flying MRs I bought some cheap arming switches without fully understanding the amount of current we are dealing with. Learned my lesson when the switch fried and failed in mid-flight. I just ordered the SPS SafetySwitch and am glad to have read your post.

Castle recommends not using a spark protector on their esc's. A nice spark show that your capacitors are doing their job, plus the switch is another thing to go wrong in the chain.

I wondered if that would work as well. Connect a small 2s battery to the esc's first. I know the maytech escs held a charge for a few minutes. not sure if they all do it.

After some testing, it looks as though we'll need to upgrade the motors - they get a bit too hot in this 100 degree weather. We could do it with the current setup, but it would be pushing the rig harder than I'd like.
Hi Benjamin, just curious what format your clients planning for release that they would want to fly the red? Have you had a look at the canon c300? Half the weight of the epic and the image is freeeeekin gorgeous! We're on stage shooting with Miss Alexa this week, now there's a camera built by filmmakers. Our lighting is knocked down so much that to your eye it looks like we have no lights on at all, but you look at the monitors and it looks like we're blasting 9 lites through the windows.
Enjoy your videos very much.

With that kind of value (camera + copter) involved, nobody right in his mind would use a castle BEC. Search the net and you will know what I mean. The only BEC I trust is the Herkules :
http://helidirect.com/advanced_search_result.php?keywords=Hercules&x=12&y=18
After 20 years beeing in RC helis, cars, airplanes...I have tried just about anything avalible, and the combination Hercules BEC + Emcotec SPS Safety Power Switch is the ONLY combination which never failed in all those years.
Neither is it very clever to have a fat spark next to your camera and your copter electronics nor does it any good to your connectors. Every time you produce a spark, your connectors get corroded a little bit...so you never know when you see the last spark in the life of your equipment.
Btw...the Emcotec doesn't have a mechanical switch - which could fail - , it's operated with a magnetic switch.
I don't want to start any off-topic duscussion here, but it's always amazing to see how much value is sent into air without taking care of even the most basic precautions concerning "remote control" and electrics....
Best regards

This is an interesting debate about the switch vs. no switch. I'll need to look into this more.
The clients want to shoot with the Red Epic because that is what they use for their productions. They want to stick to the workflow they are use to and they want the cameras to match. Can't blame them. I'd want the same thing.
The C300 puts out some pretty images, but I'd have to rent one, and it doesn't have the same resolution. Alexa is awesome - maybe one day they'll make a lightweight version.
I'll let you guys know how things pan out. I'd say bigger motors are in my future.

If you go for bigger motors, just make sure you get the matching ESP's (speed controllers). The best bet is to have ESC's operate at about 70% ~ 80% of their capacity...if they are too big and you use only, let's say 40%, they get very hot...if they are too small, and operate on their limit, you have no reserves....and give them as much air as possible for cooling.
It's all about efficency between propellers, ESC's and motors...and it's always a pain in the a** to find the sweet spot.
