Re: Are Switch kites getting any better?

Hello Tegirinenashi: Here are the Nitro4,5,& 6 canopies overlaid. Nitro 5 had minor flattening of the wingtip profiles from T3 strut out and a slight bit of additional sweep. The major change was the 'Spider' bridle. Nitro6 as mentioned previously was completely re-profiled and the LE was curved mor...

Re: Are Switch kites getting any better?

Nitro6 was a comprehensive time-consuming revision from Nitro4 & Nitro5 while preserving the AR and general appearance. The kite's canopy and struts were totally re-profiled to reduce drag and add stability. The LE tube was changed to add sweep/curvture in the shoulders for better relaunch. The stru...

Re: How to ruin your vacation with Core

@JBrook: http://www.kiteforum.com/viewtopic.php?f=1&t=2392616 Failures in crashes on water can be sewing/construction issues like misplaced bar tacks or lack of reinforcing. Prior damage or wear and tear are also a factor. 'Tomahawks' cause canopy tears along the center strut. 'Whiplash' crashes whe...

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...

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...
