APC 12x6 props - Order codes and links

[sausageroll]

Thought since I have finally found some better than Gemfan props id do a nice post for it with the hope that people may dig this up with a search in the future and find the information useful.

The props are APC, distributed by J Perkins in the UK. The codes are:

LP12060EP (tractor)
LP12060E (pusher)

They can be bought from Hobbystores, a complete set of two of each prop with delivery is about 22 quid.

They look stronger than the normal cheapo types that are about looks to be a bit more meat near the hub, do you balance your props ? although the APC props I've used in the past always seem to be quite well balanced

Ive not had to yet, I have been building quad rotors approx. 2 weeks so far. Ive only ever had the gemfan ones.

Sure i can balance this some how with some bit of something in my garage somewhere...

A couple of videos here that are worth watching, well balanced props will cut down on vibrations

As Gaza07 says balancing your props is really worth while, it can make the difference between a good video and a poor video

There is the reason your breaking props! Your probably getting the imbalance resonating through the quad causing them to fracture. Everyone else including myself uses cheap chinky props and they don't break in flight. Everyone I put on the balancer is well out so I can't see you not having any out of balance. Buy or make a magnetic balancer and I think your problem will go away.
You mention there not being much meat near the hubs on these props. electric props don't need it, Props on IC engines do because  of the pulses on the combustion stroke.

Got the APC props today. They are very solid and balanced perfectly out of the bag. I will have a much higher level of confidence flying the quad with these props on them. The root where the blade joins the hub is a much better design.


Incidentally, I used my new prop balancer thingy to test the chinese props and they are miles out. It took one Blade MCPX tail rotor balanced on the end of the light blade to get it in balance!!

They do look much better and much stiffer I would think you will get a much more crisp feel to the control as the prop wont be flexing all over the place, most of the cheap props Ive used have been out of balance but not as much as yours sounds like vibrations may have caused some of the failures you have had, look forward to seeing your reports with the new props

That's a first! APC's are usually terrible. I have never had one anywhere near balance out of the bag.

They do look pretty good out of the bag, there are some videos on here that show how to balance props including how to check the hub, you should be able to set the prop at any angle and it should stay in place, not just horizontally
