main shaft spacer question

[kipper1]

so now that I have 20-30 flights on my 700e 3g I picked up the heli after a flight and noticed some vertical play in the head it's not alot but i never noticed before. everything looks fine I am wondering if i should use a thicker spacer for rhe main shaft in between the swashplate and top bearing block you can clearly see the play there when picking the heli up by the head. any suggestions would be greatly aapreciated

thanks

Try the thicker spacer.

well thats what i am going to do today if I get time. I was just a little concerned that play wasn't there before. has anyone else come across this and or do you guys have a little play in yours?

Yeah, mine do it after time. I've found that sometimes trying to go the next size up makes it toooo damn tight to get jesus bolt back in. I got so tired of my 550 always 'loosening' up I actually took the spacers our completely and it still flew just fine. Do what you can, just don't make it to tight. Another thing you can do is loosend the upper bearing block and try to pull it up and retighten, this has worked on my 700 nitro.

hmmm I wonder what is streching to give it play like that when it was fine before. Maybe the bearings in the main and auto rotation gear are compressing the plastic gear material making the play.

Yeah, I used to try to figure it out then after I saw it happening to a lot of helis I just accepted it as being 'normal.' I do what I can to get rid of the play during the build, then never really touch it again after that.
