yes, with all things considered equal but, it has been proven that the gws props with it's lighter weight (less rotational mass - better acceleration/throttle response and overall less weight - better AUW ), different airfoil (overall shape is different and it is thinner - more efficient) is OVERALL more efficient than apc props of a similar size. then there is the built in "prop/motor/motor mount saver" effect of a flexi shaft upon impact.

a theoretical rigid gws prop may be more efficient than a flexi gws prop and
a rigid apc prop may be more efficient than a theoretical flexi apc prop but
but there are more variables in the real world.
it has been tested that a gws prop overall is more efficient than an apc prop of a similar size for these relatively low power applications

gws props are extremely popular for a reason (the small props have only a few cents cost difference between gws and apc so cost isnt a factor)

it would be highly amusing if i ever see somebody using an apc 7x4 sports nitro prop as that would be the most rigid and inefficient prop lol

anybody want to even bother testing an apc 7x4 sports prop just for laughs? maybe an apc 6.5x3.7 pylon combat?

fyi - f3p (i know not the same as this) "pro" pilots use gws. haven't heard of any using apc

I'm wondering the same thing about E Flite, SCAREY

UHHHG ! why is everyday WINDY ..... 15+ winds with gusts......... the simulator is only satisfying so far.... then the "itch" sets in...... this "itch" has to be fed !

MINI-FLIGHT REPORT: FLAPERONS/SPOILERONS


Okay, so before maiden, while I still had the plane on the bench I had gone ahead and programmed in traditional flaperons with elevator compensation, so that I could play with it later. But then before trying it out, I read that on a plane with this much wing, and the ability to fly slowly, traditional flaps are not the way to go, but to instead configure them as spoilerons (both ailerons go up instead of going down when deployed).

Having played around with using reflex to delay the onset of tip stall for a few RC models (Stinson, RadJet, Komet, etc), I was already sold on the ability for a bit of reflex to help with low speed stability and handling.

Set Up: I used -40% and -60% for low/high spoiler settings, and since I was not too sure how much elevator compensation might be needed, I left it at zero (was originally at -5 and -13% respectively for traditional flaps). Just eyeballing it on the bench, this seemed to be a good range of movement to make a change to flight, that I could evaluate.

Observations: From level flight, I slowed the plane down, headed it into the wind at about 1/3 throttle, in a slight nose-up configuration, but not quite a full 'high alpha' stance. I selected low spoilerons, and the plane slowed down further at the same throttle setting, but the attitude did not change remarkably. Perhaps the slower speed would have normally made the nose fall, but the spoilerons tended to nose up, so the two effects approximately canceled each other? All I can say is that at same throttle setting and same elevator input, low spoilerons merely slowed the plane slightly, at same attitude and altitude. I went ahead and flicked in full spoilerons, and by now I needed to add a touch of throttle, but it clearly had the same impact only more so -- flying slower, but no dramatic pitch up or down in attitude. By now, though, I was in full high alpha, and approaching a hover. I held it to see if wings rocked, and I got zero wing rock. With my low skills and a bit of wind, usually I do get a bit of wing rock, so it seems possible that the high spoileron configuration helped settle the plane in, but I can't swear to that after only one test.

I switched back to zero spoilerons and flew out, and everything was cool.

Time to test the real reason I wanted to try these -- for landings. So I skipped the low setting and on the next slow approach, ready for landing, at about four feet up, and just above walking pace on final, I hit full spoilerons. The plane slowed down, kept the same attitude, and began to lose altitude more rapidly. It quickly 'plopped' to the ground, almost on all three points simultaneously. This was not a stall; the wings stayed level and it was 'flying' but at a descent rate that was higher than I would want for landing. I suppose if I had the presence of mind, I would have spooled up throttle as I hit the spoileron switch, to make it 'hover' like. No damage, no problem, I taxi'ed in, but when I looked at the gear, they actually were splayed out a bit. I've had to gently bend the landing gear wires either fore or aft after a hard landing, but this time they were spread edge to edge. No big deal, just a quick bend to set them right, but I think a traditional landing, with no flaps or spoilers, is going to be a lot better for me.

Conclusion:
The spoilerons acted as predicted, and so someone with good stick skills might find them fun to play with, but they are definitely not required, and at my skill level, could actually be a little dangerous to play with.

But to a certain single buyer (which is all it takes)? I'd say probably ought to appeal, since it's a proven plane, debugged, equipped with the better prop, and shipping included... if it's sold out in someone's area, this might be a very good way to go.
That add was plus shipping...

all should be less than $12 to the door

they used to have a kit where you could wind your own motor but i can't find that

I recently broke the prop on my Edge, and have replaced it with a GWS 7035 but haven't flown it yet. Has anyone tried it? how does it fly differently?

that is hard- I'm with you Try your luck at LHS...last times I had luck with my online sellers but once, I bought my second UMX Beast at my LHS, I had to open 5 boxes to found a perfect model without damages
