Where to get Props

[sausageroll]

Hi Everyone,

Having a few issues with these cheapo gemfan props. Had a few now where a blade has just exploded apart in flight, once at reasonable altitude causing major damage (emotional as well as to the quad hah).

I am using 12x4.5 currently with 880kv motors from Unmannedtech. Im wondering, where the hell do you get props that are not gemfan!? Als hobbies, SMC, Wheelspin etc sell loads of props but im finding it really hard to find props that have a pusher version as well.

Any advice? Would be great to hear where you get your props from and what type you use. Been looking at APC Slow fly 11x6, would that be ok?


Thanks a lot,

Pete.

Flyduino do a good range of carbon reinforced props

Or the UavShop do a good range of props inc full carbon or carbon reinforced

Or for top of the range carbon fibre props

I'm using the standard (non reinforced) gemfan 9 inch props from the flyduino site;

and am finding they work really well.

Forgive me if im not mental about using Gemfan again...


Had 4-5 fly apart in flight, one at altitude.

Really looking for something better. A few freinds across the pond are using the APC slow flys. Cant find them here reliably though. How are those ones from.

I may be wrong, but all the props other than the carbon ones on both these sites just look like the gemfan ones... Theres gotta be an alternative!! I already have a trade account with J perkins who distribute APC in the UK, might see if they can find us something better.

Could be a goer?

Hopefully I'll be ok with the gemfan props at 9 inches but at 12 inches i think you want something stronger like the APC props.

The only thing to be careful of is that I've heard they cut through flesh like butter once spun up.

I just use the cheap ones from rctimer but I dont really throw it about and never had a prop break with out them hitting the deck 

They also do carbon fibre props check em out

I really like the look of some of the RCtimer 8 inch all carbon props;

But i don't really know if they are worth the cost and i can't justify spending money on them until I've got everything else working perfectly on my quadcopter.

In fact I've never really read a decent review of the performance difference between similar plastic, glass reinforced, carbon reinforced and fully carbon props but would love to hear from anyone who's flown from all the different general types.

When you look at the design of these gemfan props, they are doomed to fail from the start. Where the blade root joines the hub, theres just not enough meat there. No wonder they break off. If you look at any of the other props like Grapner or Master etc, they have really thick blade roots, nice and curvy with no sharp edges to concentrate the force on.

Just gonna ring J perkins to see if I can order a set of these props on account....
