Just got a set of 680mm Hirobo blades from someone. Don;t know the part number. These have brass bolt bushings that feature an embossment to fit into the blade spacers.
Anyone know a part number for the correct spacers?

The lot I got is not a lot, but I thank God a lot for the lot I got!

Ben I think he needs 0404-611 spacers as the brass bushing protrude and the spacers pick them up. Rons heli has them, their part number is 404611. I have a set of the blades as well.
(The bushing extends from the blade with a slightly smaller outside diameter).

Mike0251,
Yes! Exactly. Thanks.

Bought these blades cheap. Thought I'd give 'em a try.

New in the box they come with 4mm and 5mm brass spacers so make sure of what you have in the blades if you did not get both. The Hirobo bolts are 5mm. Don't know your heli application.
Its not every day that I get a leg up on Ben....

I did get both sizes of bushings with the purchase.
They'll be flown on my 1990 Eagle.

Yeh! Ben's a lot of help here on RR! Thanks also Ben.

I have a set NIB too. Let me know how they do for you. Do you have a 90 or a 60 in your Eagle?
I also saw in another post you made that it was cold there in the Bahamas? Really?
Its only 35f here with 50mph winds today...sucks bad.

Mike0251,
Are these spacers plastic or metal? Reason I asked is, I just had a look at these at Ron's heliproz, $10.90.

The lot I got is not a lot, but I thank God a lot for the lot I got!

Plastic (Delrin). Yeah Hirobo is not cheap sometimes. Here is some additional data to make sure of your grip thickness as well.
0404-611 Blade spacer 2T 4 For 14mm grip
0404-612 Blade spacer 3T 4 for EX main rotor blade (FRP) for 12mm grip

I have a few of these spacers laying around on my spares box. If they fit your blades I may just send you Christmas present.

I had a hunch. That's why I listed the different thickness as well. That OD on the brass is the same though.
