Hughes500Pilot Posted this I have a set they were bolt on ballanced. Good for 28$
$28 FRP Blades
I have a few sets of these blades. They look and fly great. And they are only $28!!! I posted the info several months ago on this web site, but here is a repeat of that post.
The company that makes them is "The World Models". The USA distributor and retailer is Airborne Modles. Here is a link to their web page. They also have full page ads in RCM magazine.
Once you get there, look down at the lower left corner and you will see "Parts and Accessories". Click on Accessories. Go to the bottom and click on page 2. Once on page 2, scroll down to the bottom and you will see the following two items:
FRP main rotor blade PR6200550 Fiberglass 550 mm semi-symmetrical. Clockwise rotation. 4 Oz. pre-balanced. Bolt hole 4 mm, root 12.5 mm.
FRP main rotor blade PR6200551 Fiberglass 550 mm symmetrical
If you then go to page 3, you will see the 660's and 680 blades.
Please note the web site says the root is 12.5mm, in reality, they are exactly 12mm and fit the Raptor perfectly. Yes, they include spacers and bushings for 3mm and 4mm bolt holes.
I hope this helps. -Steve
