i used the betafpv x-knight 4inch frame, first gently crash and its broken. there is no motor protection so i loose a motor aswell. it doesnt make any sense to use high quality carbon with a that bad design. seems like a sell-system.
some delaminated carbon seems to be a dream on this frame xD dont buy!

not much good 4inch ul frame options

  That sucks!

It looks like it sheered the carbon right off.

after some time, i bought a spare arm, allready i dont know why i did this...

the next crash was for the canopy, the canopy is pretty rigid - much more than the bottom plate where it is attached. the bottom plate is broken now. i can not understand, a frame cant be much less toughtfull, or its probably not a mistake - a sell system.
the canopy is well, one esc is broken, physical force from the bottomplate... xD

i can not understand why betafpv sell somthing that bad, its an art to design such a bad frame, i hadnt any frame that bad - i use several ultralight frames, no one had such issues or mistakes.

do not buy this frame, its worse a try.
i will try the tbs source podracer 4“ frame, no fear i will get near trubles with a tbs product.

the x-knight 4inch frame is a bad joke for the progress in frame-technology we have today

I had a 5 inch X Knight build and it was jinxed build for me with multiple burnt AIO FCs/motor.

The flimsy plate also broke on mine after a fairly mild crash due to the impact transferred from the hard canopy. The canopy support plate is so piss weak.

Transferred the parts to RacerX ET5 frame since and never going to touch this crappy thing again.

Another BetaFPV X-Knight 4-Inch frame casualty...
