First, it's generally understood that any helicopter, especially the Micro, becomes easier to control when slop/play in the control motions is reduced. And we all know that these inexpensive little fellows leave a lot to be desired in that respect.

I have seen a couple of Posts where a small piece of fuel tubing is installed between the head and the swashplate to "settle things down" a bit. Although I'm having a little trouble seeing the logic in this, it did get me to thinking - why not use a spring.

I pulled the swashplate of my HoneyBee 2 down using the radio system, with the trim set high. I then measured the exposed main shaft between the head and swashplate (aprox. 7mm). I cut 8mm of spring from the spring of a "click click" ball point pen, and installed same (with spring's "factory" end toward the swashplate). I then checked for: a) no servo strain (servo does not buzz) at "idle"/zero pitch; and, b) the spring is still pushing downward on the swashplate at full throttle/full pitch. Hopefully, this will reduce any play between the swashplate and the servos.

What I am trying will not work if you've advanced to inverted flight - the spring will put to much stress on the servos (I checked).

I won't get a chance to see if this helps until the weekend. I'll "reply" Saturday or Sunday with results.

Sounds interesting. Keep us posted.
