I upgraded my small "standard ones" to one mm bigger, and they look double the size! Ive seen a fair number of small standard ones fail completely now.
My upgraded ones fit the same cable ends but there is so much more meat on them and the fasteners well up to the important job of steering the whole craft. Increase in weight is perhaps 20 grams
but this is one area that REALLY NEEDS to be well engineered. By THIS I mean that simply being "adequate" for the job is simply NOT good enough when you can increase strength of a vital part for perhaps 20 GRAMS and basically PREVENT this item failing and thus KEEPING craft and occupants out of danger. ONE at each end of cable = 40 grams? Rarely can you achieve such a reliability increase for the weight of a "cadburys roll"
Ive been concerned that OUR steering fittings should be WELL up to the job as without steering you are well stuffed. (THIS part is the size of a thumbnail, but can and will disable a whole craft and does NOT necessarily occur on shore)
..YES--- I know experienced operators can angle some craft to limp home in mild conditions,,,, but NOT (EVER) in challenging conditions.
Ive seen thin rope operated by the passenger,-- (to get back to base) but rope and propellors sometimes make an uneasy mix.
I thought my modifications were somewhere in my build blog --- KingFisher 2. They dont appear to be there!
