I'm resurrecting my brother-in-law’s 30 year old Kalt Enforcer. I've got everything I need except for the main and tail rotor blades.

I've noticed that a lot of sites have blades listed by model name rather than by spec. Needless to say, 30 year old models aren't listed. Can someone point me to a site where I can buy blades by spec?

I don’t have the original main blades. The main rotor length maximum was measured as the length from the mounting hole that would not touch the tail rotor even if flexed downward. I do have tail blades, but they are chipped so they need replacing as well.

What I need are main blades as follows:

3 mm mounting hole

8 mm root thickness

505 (or shorter?) mm length.

And tail blades as follows:

3 mm mounting hole

5 mm root thickness

72 mm length.



Thanks for any help.

I went to two of the vendors that i usually visit when i need parts. They list the blades by size.

If you click on the blades you are interested in, they should give you the rest of the information you are looking for. Let me point out that "root thickness" should not be an issue, as most blades come with spacers that are inserted in the grip to take up the slack if there is any.

In my case, the root thickness is important as my rotor head has a max 8mm root whereas a lot of blades of the appropriate length are 10mm so I need to be careful.

I'll check the links you posted to see if they have something I can use.

Thank you for the info.
