Tbh I've been really busy, not had much time to fly anything and with conditions being crap, hopefully in the new year I'll have some new projects on the go, mostly to do with HAM radio, will certainly fly again soon. FTR I hate FB too   :D Merry Christmas

How flexible is your SM450 V2 (DJI Clone) airframe

I've always found it difficult to get my 'DJI' style clone frame flying well. I suspect it may have something to do with the softness of the arms and the way they react to vibrations;



There have been lots of different clone versions of this frame. I'd be interested to know how flexible other people's frames are and if they have found it difficult to get their quadcopter flying smoothly as a result.
One circlip short of a quadcopter.
 1 lobe short of an antenna.

BLIMEY you're going to snap it off!.   Yeah they all have some 'give' and I think that actually helps absorb some of the vibration.   
Mine had terrible vibration using regular motors with10 x 4.7 carbon reinforced props / apc props.

However when I tired the Graupner 10 x 5 props.  all vibration was gone.  Buy some, you'll find it gets rid of most of the vibration problems you're experiencing, I am sure.

Using the dji motors will help too but they come at a premium.  prop is mounted close and directly on the motor without the need for a dodgy prop adaptor.  Therefore mounted perfectly central and close to the motor mass.

Crikey I bet you could twist a house brick you been working out  ;)
Mine is quite flexible but I wouldn't think its that much of a problem but will show up any thing that isn't balanced properly as the arm can wobble, I get the feeling that your probably twisting those arms with quite a lot of force much more than a running prop may do, if the arm ever moved that much in flight it would cause loads of yaw and I haven't seen anything like that with mine  ~~

teslahed your frame looks like it is not built flat all 4 arms do not sit level on the table this could be some of your problem more so i would say than a little twisting as gaz said our little motors don't have that much toke
If you find yourself in danger of being taken seriously, then try to do something which undermines or sabotages that perception in some way.
