As the title says i've been out for a while (3 years) and would like to get back in. I still have all my old cars which I plan on keeping as the updated versions don't add enough to justify buying an all new fleet. What i've been having a hard time finding is what's new with electronics. I run 8th truggy and buggy with HW XR8's and Tekin T8s in both. From what I can tell those are still a good option. The real question is in my 1/10 2wd buggy, truck and 4wd buggy. In those I use SP Reventon pro 1.1's and Trinity D4 13.5 1s or 17.5 1s depending on class. Are those still a competitive option? I know there was some question of the short stack motors losing ROAR legality. Is there anything newer and better (game changing) that I should look at getting? SP seems to have fallen off the face of the earth so once those die I'll have to find a new brand. I've used the HW stuff in on road and like it but what else is out there? Fanboys chime in lol.

In summary:
Is the D4 1s still legal?
Are there any new motors that blow those out of the water?
Is there any new ESC brand I should start giving my life to?
Is what I have still competitive?
