Why are people complaining this gearbox isn't reinforced? It's a V2, it doesn't need to be built like brick at the rear, it just needs to be strong at the front. Ok so the window isn't filed like a CA for example, but it wouldn't be a huge effort to file it.
The VFC piston isn't too bad at all, I've read about people running them on 12 volts, and vfc removed the 2nd tooth in the mold which is clever.
I don't understand why people get excited over the piston head. Yes it's aluminium, that's hardly a great thing, alu head just transfer more energy to the shell reducing its life. VFC ha
