You may be right, but it'd be a big financial risk for me
I'm a student, I can design the stuff but stocking the stuff is an issue - especially on a car with relatively low demand like the TRF.
Regardless of that though, I'll follow through with the development of this. I've got two towers in 4.0mm CSC (Carbon outer layers, glass (Silica) inners layers) on my way and I'll be ordering the 3D printed parts before the weekend along with some other stuff. Stuff like this:
New thumb screws. The standard thumb screws don't have a lot of hold on the grub screws with 25mm LiPos (Turnigy Shorty packs)+Rudebits Under LiPo weights. These thumb screws should solve that, and with the slightly larger diameter (+2mm) and rougher profile should grip a bit better too. They cost me less than 1GP to print if I exclude postage from the equation... money well spent on details that make the car feel better!
Anyway, back on topic. With a bit of luck these parts will be in before the 4th of april. If that's the case, I'll be able to test it right away in my first Dutch/Belgian 'Nationals' race
It will be at the indoor track in Charleroi, Belgium - I heard it's pretty unforgiving to bad landings, so this tower design will have to work hard to prove itself!
