oh i figured out that the vibrations are causing that problem....so when i went to fix the vib issue, i fount out that 3 motors are busted....in other words the bearings are worn out and the bell of the motors is sloppy and moves around a little bit...that is causing the vib and i need to fix that ASAP

rc bazaar have a lot of bl motor bearings - take your motors shaft
size(probably 3mm) od and thickness of the bearings and get suitable
replacement.

They are one of the better LHS

What size prop adapters are u using?

Edit- I'm using same motors with over 15 crashes on concrete . Never has vibration issues. Or bell problems but I did have bell problems with odin2210 which is similar. I have shortened my shafts though.

Reduce the shaft length to just enough, leave no extra. It will help to avoid vibrations later. I can search for bearings locally. I need to get some too. Will let u know if I can find it here.

Adityaamg

sure sir,
is the size of bearings is 4x8x4??

pravesh736

I dnt knw the size exactly. I have same motors so il take out from them and measure. Please dnt callme sir. Bearing ID is 3 mm obviously .

The smaller (common 3X6X2.5) bearing is the front bearing located under the can. The rear bearing is a 3X8X4 higher capacity bearing.
