Title: Where Are The MAPA's
Post by: chilese on March 20, 2009, 05:03 PM
In general, it seems kite frames using the PT series go:

2PT: SUL
3PT: UL
5PT: standard

But when you get to the leading edge connectors, the APA set seems to have a gap:

TAPA: SUL
TAPA or APA: UL
APA: standard

I have ULs which use TAPAs and ULs which use APAs.

It's like Goldilocks for the ULs:
This connector is too big. This connector is too small.

How about the manufacturers come out with a Middle APA (MAPA) for the ULs? Then I would have a fitting which is just right.  ::)

I really haven't seen any problem using TAPAs on ULs. IMO TAPAs supply all the stiffness needed.
A MAPA would just add unescisary weight.
They could be useful if trying to add a tiny bit of weight on one of the LE points though. I know that I really liked the effect of using normal APAs for the LLE on one UL prototype.

They might be useful on the US conectors on a std, ala DS but slightly larger.

I think it would basically just be another variable to play with trying to balance a kite.

I would think that the weight difference would be so slight that no human being could possibly tell the difference.  Seriously.

4 APAs weigh about 20 grams
4 TAPAs weigh about 6 grams

My 3pt kites usually have tapa upper and apa lower. APAs add stiffness, which is generally good for a UL, but I like 'em for an entirely practical reason. Durability. If you leave your spreaders in, TAPAs dont long survive all the folding.

That's where a medium APA would come in handy. LLE connectors on UL's & SUL's.

My point was, APAs are perfect for 3PT lowers. I wouldnt want anything wimpier

I always go with the smaller fitting and drill it out to fit the spar.
