Woiw, those props look awesome.  I would love o see this puppy fly with them.

@ Jason - I can rule out a brown out as the APM shared a dedicated 5amp BEC with the video.  Plenty of power.

Speculation is welcome here!  As is any advice...

@Ellison - I really like the props.  The best thing about them is that they are pre-balanced to perfection.  That makes them almost worth the cost alone.  I only bought 6 to try and now I'm down to 5.  I need to setup a decibel meter and compare them to the 14x4.7's to see if they are objectively quieter.  The competition gives a substantial amount of points for noise mitigation and with these props, I think I can win that category.

Arashi, did you ever sort the problem out with the slipping motor shaft?  Also if you want a second set of eyes on the logs feel free to post them, and I'll have a look too.

@Ellison - Yes, it was solved by these props as they screw directly to the top of the motor.  I also spent a couple of hours on a mill making little aluminum bits that bolt to the top of the motor and have a grub screw to secure the shaft.  It was a lot harder than I thought to make these.

I am using the hobbyking 530kv motors with the APC 14x4.7 now.  I just drill out the prop center to 9mm and zip tie them to the motor.

I got the idea from this gentleman who flew for 65mins.

So, the 5010 work with the 16" props with no mods need?

Comment by arashi on April 22, 2012 at 10:17am

@Ellison - Yes the the 16" props have 3 holes drilled that align with the holes on the top of the motor.  You just need (2) 3mm screws to secure them.  No need to worry about the shaft slipping.  The verdict is still out as to whether or not this setup is better than the HK 530kv's and 14" APC's.

I uploaded the logs from Mission Planner.  It is a 1280 board, so I don't think there are additional logs on board.

So, neither the motor or the props came with the mounting screws?!  Ok what's the length of the screws. Yes, I'm thinking about getting this motor and prop combo too. :-)

Could you just attach the logs?  I hate using those download services.  Full of ads,  and pop ups.

I would just attach the logs, but I don't know how.

Neither the motors nor props came with screws.  The motors came with collet prop adapters that don't work since the shaft isn't locked to the motor...  The zip tie trick also won't work with the 5010's as there isn't enough space under the rotor and the rotor supports are odd numbered. These motors were obviously made for the 16" props.  I was just not literate enough in Chinese to properly ask this question of rctimer.

The screws are just M3 screws with 6mm of threads extending below the head.

Oops, no attachments in a blog. Strange.

Maybe you can add them to the 2.5 discussion, if you're running 2.5 or just start a new discussion on the crash.
