At that point it is a guessing game to determine how much and which blade to add weight. I always start with adding tape to the center of the blades but there are times where it had to go a touch towards the root or tip to get it perfect.

On another note, I have completed test flights on one my mod'd 4F200's and initial tests were very good. It is solid in hover and FFF (no 3D yet) and comes in at AUW of 318g. Nice. Here are a couple of pics.

What do you guys think? Is anyone interested in the mod? Just trying to see if there is a want factor.


Awesome Darryl, nice work!
I would want one.
