Very good propeller, needs a little bit of tape to balance them but they work well.I got these to upgrade my 350QX. I first got a set of the 8x5.5 plastic props. They were awesome added speed and agility, I did lose some of the hover and slow speed maneuverability.
So I thought well if the plastic set did that well the CF set should set this little guy off. It should be the same except with no flex in the CF props it should tighten it up and make it very crisp.
Well I was wrong. These Props SUCK ASS!! They create half the life of the stock props. with a full charged battery and full throttle the 350 would barely get off the ground and I just about put it into a fence just trying to keep the thing up.
my advise, just get the cheaper, better, faster plastic 8x5.5 props. save yourself the $5 and the crash that WILL happen with this poorly designed zero lift propellers.These plus the adapters are totally worth the 5 stars. I was surprised with how much quieter AND lighter they are compared to their plastic counter parts.Tried these on a Blade 350QX (with mount adapters) and they were so un-balanced, the quad was almost lost. Even after balancing, the quad was very unstable, so I took them off.I put these on my 350 qx2 and I find that they work really well , they fly every bit as good as the stock props ,as well as being alot more resistant to crash damage .Very good props. Reamed them out to fit a 5mm shaft.
Took very little to balance them. I have them on a qav400 and its silky smoothgood price, but need some balanceI have the HK CNC prop adapters and these props on a QX350 and they are great
Bad to hear 69Maverick has problems.
I actualy am now trying to order spares, as I am happy with the performance.I put the Carbon blades on today and they do not perform well at all. My 350QX flys perfect with stock blades. it surged and never really stabilized as it does normally. I tried the plastic blades and they were better but the stock blades were still better. On a high point the adapters fit perfect!
