DJI Phantom Self Tightening Props balancer rod

June 23rd Update:
I have lots of the rods already made so there should be no waiting time. Just contact me if you need one.
But that's not my latest update.. I just want to let everyone know that this afternoon is my wife's final (I think) ultrasound scan so we're both looking forward to it in just over an hour's time. And this time, I will ask them confirm the sex of the baby and make sure she's definitely a girl - the baby room is all pink now including clothes so, for the baby's sake, I hope she's a girl!

June 02nd UPDATE:
I have a few more ready made available if anyone needs it. Just PM me or email me



MAY 22nd UPDATE:
I will be away this weekend until Wednesday. For those asking for rods this coming weekend, I will be shipping yours out Thursday next week.
I will be doing my usual shipping out of rods tomorrow, Friday. Thank you again for your continued custom. Weather this weekend here in the UK is crap so no flying for me!

MAY 3RD UPDATE:
I shall be mailing rods out on Wednesday.. If anyone would like a rod, please contact me and I can include you on my list for Wednesday's shipment. Thanks and enjoy your weekend!

APRIL 25th UPDATE:
For those who are already on my list since Easter weekend, I have received my aluminum so I will be busy this weekend cutting and threading rods for you guys.
I shall be mailing rods out Tues/Wed so anyone else who are interested, just get in touch and I can include you for when I ship them out.

APRIL 16TH UPDATE:
First of all - thank you to those who have asked me to make the rods for themselves.. I really appreciate it. The extra money in my pocket helps towards...baby stuff!
We are expecting a baby girl in August.


I will be away for Easter Holiday so anyone wanting a rod, please contact me today (Wednesday) as I'll be packing and shipping rods out at 2pm GMT time - anyone who contacts me after that, I'm afraid yours will have to wait until Tuesday (April 22nd) next week.

Also - the motor balancer, I'm afraid my design is too complicated and my first try at a prototype kinda failed... I'll have to ask for expert advice next week.. so it's probably in May before I can get a fully working one...

March 31st UPDATE:
To those who have been asking me to make a balancer for the motor as well... Just to let you know I have designed one and will try and make it in the next 2 weeks to test.. and if all is good, I shall let you all know.

The new design is more complicated and a bit more work to make though but it's to ensure the most sensitive way of balancing the motor... and also prop (yep - it can be used for the prop as well)

I won't post much - until I'm ready to start making them...
If any of you are interested, just let me know on here so I know roughly how many people will be interested.

For the time being, I still have a few of the balancer rods if you guys are interested. Just drop me a line.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I decided to make my own rod for balancing the self tightening props of the new DJI Phantoms and Vision.
If anyone is interested in buying a rod, please PM or email me: muscleflex@hotmail.com for price. Thanks

Rod has LH thread and RH thread on both ends to accommodate both types of props.
DJI Self Tightening Prop Balancer (0 min 31 sec)





I use a lathe machine to ensure the die is aligned with the rod when I cut the thread. I'm tempted to etch LH and RH on the ends of the rod but I worry it might affect the balance of the rod so I'm afraid the rods will have no markings on them.
Rod all secured:


Die in holder:


Rod greased up and Die in place. Using the lathe's drill bit (don't know what you call it) to make sure the Die is perpendicular to the rod for best alignment of the thread:





I ship them like this for protection (I hope):

I am tempted to get one, but am also thinking about ditching the Phantom props and go traditional. Argh!

If you're gonna use the old props, then yes, you're right - you won't need this.
I was gonna use the old style props but I prefer the self tightening version because you don't even need to tighten them! And they're so easy to remove after I've done flying (I take the props off to put in the case so the props don't get squished by the foam)

Tried a set of Vision 2 props on my Phantom today. Lots of vibration but did not balance them. Put old ones back on. Vision 2 props are really close to each other and someone said they are in their own prop wash. Don't have enough experience yet to comment on that.

Also if I understand correctly, if you switch to the regular props, you are totally depending on nuts to keep them from slipping because there isn't a flat side on motor shaft. Is that correct?

^^ You could be right - I have no experience using the old props. if you ask in the main forum, I'm sure someone will tell you... but if I were you, I'd just stick to the standard ST props!

I took one of these and it arrived quickly and well packed and works just great.

And anyone who's seen some of my posts in the threads will know what a miserable, grumpy, hard-to-please blankety blank I can be, so you can be sure if it wasn't great, I'd say so.

Buy one, especially if you're buying 'clone props'. You'll make a saving on the props which will pay for this and then keep on making savings.

It's a no brainer, really.

Yep - should get to you by the end of this coming week (let me know next weekend if it hasn't but it should do. First guy who bought one from the states got it less than a week)
