Default Motor Start Up Sudden Jerk

Is there any way to stop the heli from twisting when you first start to bring up the throttle? A soft start would be better.

I don't see a way around it if you prefer to start off in an IU mode. There is always a normal mode with a linear TC?

It sounds weird but mine did the same little take-off dance in normal mode. It moves around a lot less less in IU1&2 during take-offs. The strange thing about it now is that mine no longer does it when I take off in normal mode. I've got a little over 100 flights on it. Could be I'm lifting it off quicker now but I don't think so. That or I broke the horse in and now we have bonded.

Set it in grass or on a piece of heavy rubber. It will grip the skids and stop some of this. I've had trouble with all the Blades doing this even from the MCPX.

This sounds like the only fix for the 250 CFX startup, either the grass or a large rubber sheet. I have several jet engine covers that cover up the intake or exhaust when not being used that might work. When my new main gear shows up, I will try them & report back. It will also keep dirt out of the gears & bearings as an extra protection.

Putting small foam dampeners on each corner of the landing skids will make the chicken dance go away both on initial startup & landing. It makes the heli stick like glue to the deck. 1/2" or smaller is perfect. Larger just gets in the way.

The Spektrum DX computer radios allow you to set up a delay on throttle hold which will do the same thing as a slow startup. I don't know how far back in radio generations it goes, but it's in the current lineup.

Go into the throttle cut setting, then set a delay of say, 5 seconds, then watch the throttle channel on the monitor when you flip off the throttle hold switch.

It should take the amount of time you set to run the throttle up to the center point.
