Ok. Not an ideal splitter for all intents and purposes, but I just built my own for the heck of it. 1/4" thick lexan, carbon fiber wrapped.
Also, my wing is mounted fairly low, more like a spoiler, and is adjustable. I will see how it does at NJMP in two weeks. This was a FT86 SARD wing (got it for a steal) that I custom mounted with brackets which fit on the edges of the hatch. No holes drilled!
I know there are ways to improve on what I have, and I could have kept going, but I'm not a fan of the large roof-height wing nor long 4" splitters with canards. I'm going for subtle right now.
Also in the works is a custom rear diffuser similar to FancyWide, but integrated with my current rear diffuser. I doubt the diffuser will do much, but I have many holes/pockets underneath the rear which need to be filled.
