flexifoil spars(normal or ultra flex?)

[jock]

as many of you out there own various sizes of stackers, can you please give me your opinions on the two differnt spars and their advantages?

ok main difference is the ultra flex spar is lighter and more flexible so allows the kite to fly in lighter winds. For £45 a spar (i think) i didnt think it was worth it. My advice is fly it like it is and save the £45 to put towards a 4 line kite.

I've got Ultraflex spars for Stacker, ProTeam and Super10.

 

The most expensive (Super10) was around £30 from Mullin Kites.

I have found them really handy to have on the ProTeam and Super 10 as they seem to reduce the minimum wind speed to about 3MPH - although self lauching can be difficult so I'd make sure you take someone with you!

 

Less useful on the Stacker as it only appears to lower that to 5MPH when I could be flying the ProTeam anyway.

 

I haven't tried stacking them on the Ultraflex, as I think that may be pushing things in very light winds.

 

Hope that helps,

I paid about £20-25 for mine for a Super 10 from Airborne Kites. IMO they are a must have if you have a Flexi as they give you a much larger wind range.
