Does anyone here have had the following problem with flexifoil 6 ft. stacker? When turning the cell at the outside of the corner collapses and starts flapping. It's an oldie, but it has flown well for a long time...
Really hope for a solution..
remember: amateurs built the ark .. professionals built the Titanic.
Two things make flexifoils flappy- either too tight on the spar (move the inner grommets in slightly) or the fabric has become porous and is bleeding air (it only takes a tiny amount of bleed to ruin the inflation). No real cure for porous flappy- some people have tried spray on waterproofing but this only lasts for a very short while. When first starting up production of 6ft stackers we had a big problem with Windmaster fabric which became porous very quickly, led to a change of manufacturer (went to Carringtons for many years).
