Re: DIY onestrut kite

Kites do not sit directly overhead due to drag. That means the towpoints are in front of the kite. Not directly below. CAD software can approximate the positions if the user arbitrarily predicts the drag angle, towpoint separation and bridle length. In practice, the towpoints move during sheeting an...

It would require a sophisticated workshop and a very time consuming and precise process Even if able to pull apart glued and sewn seams without stretching the pieces, holding them dimensionally secure in place and digiti...

Re: DIY onestrut kite

Hello BWD: My approach is your #1. Occasionally, several identical protos with one variable change. This was used on the Legacy to optimize slack. I see in promos for some brands about dozens or even hundreds of samples being made. Pick the best and bin the rest. Expensive since most wind up in the ...

Re: DIY onestrut kite

While conceptually possible, picking apart a kite and duplicating the components is practically impossible, especially the canopy which is to some extent elastic. It would require a sophisticated workshop and a very time consuming and precise process. And, copies can never be better than the origina...

Re: DIY onestrut kite

@ Bletti - As a cost-saving measure, Switch has eliminated all in-house product development and testing in favor of outsourcing. As a result, I no longer have any involvement with Switch and the last 6-8 months of my kite development including the monostrut series has mostly been discontinued by the...

Re: DIY onestrut kite

Hello Kitexpert: I think I'm going to make LE seams like Switch does it, then angles between segments are perhaps easier to manage by first taping and then sewing. All Switch kites (to date by my designs) have constant curve leading edge tubes. If you are using segmented construction, which is typic...

Re: DIY onestrut kite

Hello Bwd: My investigations show a number of performance variations. Turning speed/response and overhead stability/drift in particular. There are also a number of possibilities including short struts, non-profiled luffable struts, profiled struts, floating struts free of the canopy, partial canopy ...

Re: DIY onestrut kite

Understand the bladder(s) are a significant portion of the weight at about 115gm/sqm. Around 500gm on a 9sqm monostrut kite not including valves.

Re: DIY onestrut kite

Hello Kitexpert:
Looks cool!
I'm currently testing these for hydrofoil use. Both have either straight (luffable) or profiled user remove-able center struts and short fixed no pulley bridles. True 9sqm weight is 2Kg without strut, 2.5kg with.
Cheers!

Re: Low AR foil kite

Hello Stef: AFAIK, Switch has no plans to add ram-foils to the product mix other than the Trainer foils already offered.

Hello Kitexpert: No kite is perfect in every way so there is always room for further development.

Cheers!
