You be needings a spur gear for that there car. The smaller the spur the higher the top speed will be, but make sure to Google tl01 gear combinations to find out what size spur it can run
Two options:
Turnigy 5200 2s (Pack size: 139x46x26mm)
or
Turnigy 4000 2s (Pack size: 134x44x22mm)
If the bigger pack fits OK I would like the extra run time.
My measurements find the TT-01 battery compartment to be 141x52x26mm
So the depth of the battery is cock-on the compartment depth. Will the bigger one fit OK?
Last few years I've been spending time/money on my 1:1 instead of RC's
I bought a Mk1 MX5 looking like this
Then new suspensions for the lowerings
Then new wheels
Then painted the heart
Then new exhaust (bad photo)
Original old man boat wheel

On track at Castle Combe
On track at Donnington Park
De-cat for better sounds and richer smells
I've now got new wheels again but dont have any photo's yet. Definately recommend getting your car on track if you are considering it
