Default why QHOR is more stable than normal FUN FLY models ?

Hi
you know QHOR can do harrier and hover easily and this models is very stable in high alpha flight , but normal FUN FLY model cant easily do and they normally not very stable in high alpha flight , can anybody explain me this phenomenon ?
Thanks

i think it has to do with the wing...the area on those things is rather large, also the shape of the airfoil has alot to do with it.

i think it's because of the huge cord it makes them so resistant they can;t rock as easily

Harriers well, that's about it... Have you tried rolling harriers? It won't do them! The wing controtsa all over and stopps rolling. POS.

What's QHOR? If you are talking about spads, they cog, bounce and get stuck inverted in rolling harriers. Other than that, I like flying them!

Yes we are talking about SPAD QHOR , i cant do nice roll with it , but i can do flat spin and harrier well and nearly hovering .
Are you think if a normal FUN FLY model with same area and chord , will have same characteristics ?
Thanks

Does QHOR have a symmetrical airfoil? Symmetrical airfoils are almost mandatory for good aerobatic qualities in my opinion.

I leave my-self open to attack...

qhor has no wing section at all just flat sheet.

dont need symmetrical section for aeros!

Flat sheet can be used, the stuff you see in a SPA3D works I guess, but I always prefered a proper section.

Well I always use symmetrical for aeros.

I think it has to do with the fact it has no proper section. Because its not really genarateing lift like a proper section does, by air pressue differential, it doesnt stall like a proper section ie "wing rock"

shahid, a sym section doesnt generate from the differences between pressure on the top wing and bottom. a sym section uses the angle of incedence to creat lift

A sym is equal lift in both directions, it works by angling it, yes incidence but mainly AoA. It doesnt need incidence I think

I leave my self open to mauling.

because you see pattern planes with sym and no inccedence.
