Its a GWS 4040 prop. It gives it much more speed now that will make you smile but it may be followed by showing off which leads to a frown...

But you have to get the prop and a adapter for it. I cant remember where mine came from but it makes the stryker a rocket.

My 4040 went straight on. No adapter needed

Just be sure to put it on "backwards" as it is a pusher!

Is there anything you can do to improve knife-edge performance?

Finely tuned mixes are mandatory, but even then, I think only QQ can pull it off!

I can usually get a knife edge but its only in a small section of throttle that is really hard to find.

Couldn't get a GWS4040 but I saw an APC 4.1 X 4.1 so I ordered one of those. Lets see what that's like!!

My bad, was thinking of another plane with a adapter Now that im looking at the motor the 4040 just dropped on...

What about thrust?

I'm looking for more extreme vertical?

Or is this prop just for speed?

It's a bit of both. I think is a little more flat out speed than vertical but its a huge improvement over stock.

personally i have not noticed much of an improvement over the stock prop.
anyway,i digress... finally got round to trying flat spins today. was easy! dont know why i was so cautious of trying it. once the first one was out the way i did one after the other for 4 batterys.

love the fast spin,it looks really good.
on the last one though i left it too late before pulling out (story of my life,3 kids later! mwhahaha!) and it went nose in. damage was pretty bad. more or less snapped it in half behind the board. snapped the nose off from about a 1/4 of the way into the battery compartment and ripped a servo off. oh,and broke the fuse cover in half too,just good measure!

not sure im going to be able to fix it this time. which sucks :0(

up until the crash i was going to try it on my big stryker too,but didnt fancy taking that one home in bits as well. think i will wait until i can practise more with the um until i try it with the biggun.

You need good batteries too. Mine became a monster with Hyperion batteries and a 4040.

LOL

I'd bet, though, that with a little Gorilla Glue (white) you'll be back in action soon, as good as new.

that could be the reason then. im running 180 nano tech and i have a couple of 300 nano as well,dont really notice much of a difference really. might go back to the stock prop as i dont seem to be getting quite as long duration with my current configuration. might just be my imagination though.

No, 4040 does have shorter flight time, and the 180 is not enough, I say you cut out some foam to push your nt 300s back to get the cg right.
