Blade adapter? help!

[mightymouse]

Hey guys just bought some new wood blades for my Hurricane 550 --the blades ar Mikado's 500 mm---I have got them balanced and they didn't need much for the balance .. now I just noticed they don't fit snuggly into the girppes and I had to pull the brass pins out of the blades so the bolt would go through. Do I need an adapter to make them fit like there suppost to or do I use a washer on the inner part of the grippes

I 've been flying my trex 450 for awhile and now just got this 550 and I'm new on this heli so I'm not sure --just asking some of you experts that may of had this problem. thanks for listening

You use washers if the blades are loose....

unless you meant the brass bushes thru the roots...those you need...

only if you use a 3mm bolt.. if using a 4mm bolt you don't need the brass bushings..

if the blades are not getting tight in the grips, there are a couple things that can correct it... both are washers either shims between the blade and grip (preferred) or washers added between grip and the nut (allows it to compress the grips enough to tighten the blade)

thanks guys --is there shimmes I can buy? or do you mean shimm it with the washers? and not sure on the mm of the bolt but it would not go in with the brass fitting in... but when I removed it --the bolt fit prefect and snug into the root hole.

thanks again

shim = washer

[mysticmead]

oh yeah... stock plastic grips use a 3mm bolt.. the CNC grips use a 4mm bolt

Thanks Mysticmead --I have a 4 mm than ok I really apprieate the help

there are "official" gaui washers http://www.readyheli.com/204352_Wash...e_p/204352.htm

Those are 3mm washers
I just opened mine up to 4mm and they worked fine.
There is a new set out as well 204631 for 4mm (cnc grips) and 3mm blades.
