ORIGINAL: GrrlsFly!
I've already added a bunch of weights. [

] Glued them right to the stick behind the motor. I didn't know what else I could do because I had to cut the stick way back just to make the connectors reach the speed controller.
Does adding lead weights affect flying performance? Why is this a bad thing?
Hold on there a second Hoss, I know you're all excited and want to get out and fly your new bird, but you need to be sure she's set up correctly.
I saw in your first post you built this bird. Is it a kit or just something you made on your own?
Do you know the correct CG (center of gravity) location for it?
I'll be glad to help you out, but I /we all want to be sure you have a set up that will give you the best shot at actually flying.
In answer to your last question, yes and no, adding weight will help get it balanced correctly, but also more weight means more load for both the airframe and powertrain to compensate for.
