Hi all,

I'm looking for the diameter and the length of the BMK Mamba Upper Speader : UL & STD.

Thanks in advance.

Thanks for your reply DD.

But why my question ?

I own a (very nice) Blue Moon Mamba # 66.

The Lower Spreaders of my kites are SkyShark (3PT or 5PT probably) but they are not marked/printed.

The Leading Edge is spinnaker, not Dacron.

My Upper Spreader has a .220 diameter, probably Avia.

I was wondering if my kite was an UL or a STD and thought that the US diameter were different between the two models.

Thanks again for your help.

Kind regards from France.

When in doubt, go to the source and ask Ken

If your US is .22 then you have a standard.  Ken's ULs normally use a .157 US.  Your lower spreaders should be 5PTs (fairly stiff similar to a P200 tube).  Your LEs are P200s with a P300 spine.

Earlier Mambas all had spinnaker LEs I believe.  Do not know when that changed.  I had some of mine replaced with Dacron.  The half oz difference matters little with a 10oz std kite.  You could also reframe as a UL  Smiley

Nice kites either way.

Oh yes, 21 1/2" US on both models.  32" LSs.

Thanks for your reply DD.

How was framed the Mamba UL ? US : Avia. 157 but :

- Lower Spreaders
- Standoffs : internal and external ?

Was the leading edges in nylon for this kites ?

Thanks again !

Specs from the BMK website below.

While the UL is a fine kite, I suggest that if you only have one Mamba you should leave it as a standard which is the most versatile and already flies pretty low. My opinion.

If you want to tinker with the standoffs, you can get a little more from the Mamba but it is a great kite just the way it is. 

Note that later Mamba Stds had Nitro LE and later Mamba ULs had 3PT LEs.  I actually liked the P90s better but small difference and personal preference.

Many thanks for this very detailed answer Stapp59 !

Is the leading edge in Nylon or Dacron for the UL Mamba ?

Standards have a 3.9oz Dacron LE tunnel, ULs have 1.5 ripstop LE.  The rest of the sails are the same.  About 1/2 oz difference in sail weight between the two.

Early Mambas all had Ripstop LEs for a while, including Standards.  Not sure when that changed.

Many thanks for this very detailed answer Stapp59 !
