I've nosedived a plane from 50ft up with a 7x5 and the prop didn't break. I've had alot of bad landings with a 6x4 and it has not broken yet. But today I broke two 8x4s from landing perfectly! Does it seem like apc 8x4 props are significantly weaker than the other props?

APC props are a little on the brittle side in my opinion. They are supposedly more efficient than other props though.

Yeah, apc props snap instead of bend. I might use gws 8x4s instead of apc.

I am not using any 8x4s so don't know but it does not seem logical, and I do not see how any prop could be broken in a "perfect landing".

The perfect landing I'm talking about is coming in and cutting the power about a foot off the ground and pulling up so it lands tail first then the nose. Either way, the prop should not have broken. It was a very soft landing.

If the prop is still turning when you landwt can get nicked or break. Program your ESC to apply the brake when you cut throttle, then make the cut high enough to allow time to get the prop horizontal before touchdown.

That would be a nice esc feature huh. "landing position" for slot planes and the like, so it holds the prop at a certain place which is safe for landing...

I've never broken an APC 8x4. Hardly even chipped. I use one on my Liteflight Bug. It's been nosed in HARD, even directly on the prop on pavement! I've been using it for well over half a year and it's just got some minor chips in the tips and a crack down the middle of one blade that I sealed up with CA.

I use GWS 8x4 and they seem to bend a lot more,so i can just bend them back into shape.After a while though they will brake.

I noticed that too, funny how you can bend them back into shape...

I just got a few apc to try, I will see how they compare...but your right about the gws, it just keeps on going, I bought a few for the cheap-n-easy and I have only had to use one...

Funny how you guys have had pretty much opposite luck as I have had. I've been through countless GWS props. Probably close to 20 now. But I've never fully snapped an APC. I've cracked the one on my Bug once, but CA has held it together wonderfully for months. Imo, APCs are way better than GWS props. I still use GWS props more for testing planes though because I can get them for about 30c a pop, where APC props cost more like two or three bucks each.
