Also the gyroscopic forces created by the large spinning prop will play havoc on the small shaft and bearings.
Yeah, that doesn't sound very good. Seems like mounting it upside down so the prop is pushing would be safer. I think I'll stick with the NX-4006... And hope that rc-timer comes out with another low kv motor like this that solves all the problems. I really like the bolt on threaded shaft adapters.

I am using 4S and never planned on going any higher. If I am not get the thrust required with a 4S battery, Abandon this project is in the mix.

Edited: Motors are rated Battery: 2-6Li-Po

yeah ..

I plan to test at 4S .. with 14in props.. first..

One thing I find is I get less flying time that what most post.

I'm at about 3400ft above sea level.. maybe more..

wanted the frame to be setup up to have that option for bigger batteries..

What is the mounting bolt pattern and bolt sizes for the 5010 motor?
As I am looking for the best props for my MT4008-600 those carbon props maybe the key to success. Could you show us how did you mount those props? Right now I am running APC 14x4,7 on an octocopter on 3s. AUW is about 3300g and I am only getting 7 min flights on 5000mAh. Which props would be the best (I can upgrade to 4s)? Or should I just try to look for better and more efficient motors (maybe this 5010?)?

According to the simulator, your 7 minutes are right.
15"@3s will raise a bit over 8 minutes, 14"@4s to more than 9 minutes.

Question please, can you rerun this simulation using six motors verse eight? Not sure of the weight differences between the two configurations.

The octo will hover at about 51% throttle, for the hexa you must raise it at 68%, for same weight. Or decrease weight a bit under 3kg.

You can play yourself, just load the page below...

http://ecalc.ch/xcoptercalc_e.htm?ec...h=4.7&blades=2

then go to motor type, switch to custom and change kv to 600. That's because his model is not in the simulator database, and this is the closest.

PS: Yes, I trust this simulator, matched everything I flown so far within the claimed 15% estimation. For hover time and Amps drawn at least.
Depending on area where you are, the page can open in imperial units, and you should switch back to metric and change weight to 3300 grams manually.

This is a very useful and handy tool, is there any possibility of making it into a stand-alone program or application for a smart phone or PDA?

Yes, code behind is known, you need a programmer
Person, not device

Hmmm, I do not own a Smart Phone but a PDA and you know, Java runs on just about every platform out there today.

Make it open source and I am sure there will be many to answer the call.
