[yaks]

[blackbeer]

Sure, I've tried them both, so what's the question???????????????/

Vess is more efficient,,

More efficient at what.................................
and on what engine;
and on what airframe;
and what type of flying:

the apc is more efficient at cutting your fingers.

Yaks, I've not run the 16x6, but I've used both APC and Vess in the 17x6 size on my G23 which is electronic ignition, lightened, and mounted on a Jerry's Big Boy.

In that installation, the APC produced a bit better thrust overall, with better vertical. It also made the idle smoother due to the greater flywheel effect from having higher mass than the wooden Vess. The Vess spools up more quickly as it is lighter than the APC.

There was not a night and day difference between the 2 props, but I do prefer the APC by a little bit. The Vess is still currently mounted on that plane because I've frankly been too lazy to change it, and the difference is not enormous. I have used many other prop brands and types in this size range and those have been the 2 best I've tried.

From my own experience, in the smaller sizes, say 17" and smaller, the APC's seem to provide the best overall performance, unless your engine struggles spooling it up. Above that, the APC's start to get incredibly heavy relative to wood or carbon props, and the spool up starts to suffer quite noticeably. I like MSC, Vess, Menz, and Mejzlik at 19" and up. Depends on the plane and engine, of course.

....and yes, the APC is MUCH more efficient at cutting fingers. I had surgery several years ago as a result of an APC 13x7 that got clipped by a Saito 80 running at high idle. ow...

I haven't tried those sizes, but on .40-.90 glo engines, the Vess was far better than the APC, in my applications.

man thats bad. i hope that everything turn out and healed well. i've heard that surgens are using apc props as scalpals now. alot cheaper that the metal scalpals. lol

Man I hear you on the cut fingers. Never had one get me on a running engine but I can draw blood just putting the dang things on.
I run an APC 16-6 on my YS110 mounted in a Velox. I fly mostly IMAC and freestyle with it with some 3D on the side. I picked up a Vess to try, 16-6, and compared the two on the same day, same weather and all that stuff. The Vess came off the plane after one flight. My up lines suffered, the size of my loops and big stuff had to be made smaller, it just didn't work on this plane/engine combo. The Xoar 16-6 out performed the APC in some aspects but it is a little fragile. Props are so weird. There are so many different ways to do the same thing. I guess thats one of the fun things about setting up an airframe, finding that combination of things that get you what you want performance wise.

Cut finger - plane was restrained, running at a high idle, maybe 3000 rpm. I had just started it with left hand holding the Sullivan starter and right hand holding the turtledeck. When bringing my right hand around from behind the prop arc, the prop thwacked the very tip of my right thumb. Frankly, it felt like I'd tapped my thumb with a hammer. But the prop split my right thumb down the middle, up to the first knuckle. The prop went through my nail, the bone, and out the other side! Yes, it split the bone in half. I don't recommend it.

Surgery was fine, and you can never tell it was damaged...but it did take almost a year for the nail to grow back.

Oh..the engine kept running.

All laughing aside, sorry to hear about that RCAddiction. Been there done that, minus the surgery part.

Sorry for you displeasure with the product,
The Vess will spool up faster,, provides more static thrust, and more downline breaking,, needless to say it will break if it hits your finger,, not cut it off like the apc,

Anyone who believes that there is a single best prop for all applications has been drinking KoolAid.

i have always used apc in my glow stuff and they always seem to be a good prop. a freind of mine he is huge into profiles and he seems to like the xoar props over apc. nothing but hard core 3d. i will have to ask him if he tried a vess. but for now he swears by xoar.
