Hi Jonathon,
Its always good to see new faces at the club and im sure you'll be warmly welcomed

, The cars you mentioned i think are 2wd trucks right? As much as these have become a hit at outdoor races we dont race them indoors on a wednesday evening lol,
We all tend to run 4wd tenth scale buggys and the motors are limited to 13.5 brushless or 27 turn brushed so your 9t will be too quick.
Take a look on the club website where Jon (Hairy Spider on here i think) has written a great guide for what you will need etc etc. and pretty explains everything

Take a look then come back with any questions on this thread where someone will answer
