Is there an adapter to fit other props?

In fact IMHO, the main problem is to find some prop with a low profile hub (of 3mm).



Classic props are more 6mm

I dont like crashes!
Not so much traffic in this thread. I thought that the X251 would be much more popular!

The restriction to stay with stock props isnt very satisfying!

With a brushless quad it should be possible to use different kinds and sizes of props.

It's not officially out yet and currently Seby is the very few that have the pre-release sample. Have to wait a couple more weeks to see some other user experience and opinions.

Like they say on TV: Stay Tuned!!

I am still trying to get one, but seems there are very few available.

I agree, that is an area where the JJRC X1 does it better. It can use basically most popular 250 size props, I currently fly mine with 5046BN instead of the stock 6040. Without the massive improvement in handling that the different props brought to my X1, I would have either sold it, or removed the motors, to install on a different frame, or replace the electronics.

I undestand that the non-ultra large choice of prop can handicap the XK X251.... but the original are really solid and well balanced .... What else ?

True, I only replaced my X1 props because the stock ones didn't give the right feeling. With the X251 the handling seems almost perfect, out of the box. But still it does force the owner to stock up on stock props, while with the X1, you can get props from many sources, if you break some.

Lets say the stock props for an brushless quad are 6040.

With 6020 or 7024 props I will get much more flight time. Also lower speed.
Can use also bigger batts with the gained thrust.
With a 5045 or 5050 BN I will get much more speed. Also lower flight times.
Use smaller batts decreasing the AUW but will have a rocket for a short flight time.

More possibilitys depending to my needs?

I see what you mean .... and yes these low profile 3mm hub props are one the weak point of this machine ...I didn't find any compatible yet. Maybe need a shaft adaptor ?

Are shaft adapters available for this kind of issue?

Would be a pity if this great quad hadnt the possibility to use different props.
