That's an awesome buggy you have, Here my current one a B74.1 i had for 3 years now. It used to be my dad's buggy and the first one bought new after a Schumacher Cougar laydown he bought off ebay to get into 1\10 carpet racing. Later than year in August 2021 he sold me his B74.1 to keep me into racing after i sold my 22T 4.0 which i tried to modify into a carpet truck but it didn't work the way i wanted it to. But after 3 years i still have this buggy just haven't had the chance to race mine a lot this year and i keep debating if i want to upgrade to a newer buggy like a 22X-4 Elite or that new B74.2 Champions Edition. But currently i'm in the middle of a lot of projects and have plans to big things next year like buying my first high end radio, rebuilding a couple of my older cars and getting a couple new ones too. So i'm not sure when i'll be able to pick up a new 4WD race buggy or maybe try to convert my existing one to a newer model. But you sure have a nice buggy can't wait to hear updates when you take it to the track.

The ESC and Motor combo i believe is a Hobbywing Justock G1 with a Reedy S+ 13.5T Motor and a Savox SB-2263-CE low profile brushless servo for the TX\RX combo at the moment is a Futaba T4PM radio with a R304SB receiver and finally i run both a SMC 7.4V 2s 4,100Mah lipo and a Protek 4,600Mah 7.6V 2s LIHV Lipo for batteries. I'm currently not sure what the future holds for this old race buggy if i am going update with newer electronics like a new TX\RX combo or new ESC and Motor combo i'm not sure. Or if i will go all out and build a completely new buggy with all new tech and just leave this one as a spare racer to take to the track.
