Top two are my TED handles, 60g. each. Many pull the 'brackets' in as close as possible while clearing the fingers, glue them with CA, and tighten down the screws very well. I finished these two from kits, but many make clones from aluminum or CF plate. This grip tape is intended for fishing rods, but tennis racket stuff works fine, and there are other alternatives. The finish is two coats of finishing epoxy, sanded after the first coat. Second coat was acceptably smooth, but some really polish the snot out of them. The sweet thing about handle kits is that you can make them fit your hand.
Next picture is Paul Walker's "Predator" handle, made from CF plate. I think he said under 20 grams. With CF, you have to bush the holes. Light weight is especially important if line tension is low, such as small models or bad trim or just when things are going "South". Better to feel how loose the lines are, rather than the weight of the handle.
Standard procedure is to use 3 stock clips and one longer than standard clip to adjust neutral. One handle and set of lines for each model. This saves a lot of messing around, flying with misadjusted neutral...a very good way to crash. My process is to use two stock clips on the plane end, and leave one on one of the LO's, and one on the other line. I leave both clips on the handle, and of course hook to the plane first and handle last, when running out the lines. Others do it opposite, but I'd rather not drag my handle across the asphalt. I think I have a picture of the Derek Moran clip bending fixture, but here's a picture of the standard Sullivan clip. I use 3 of these and one longer, homemade one.
