Very keen to build it!! Questions I have for you pros are:
Ive read about different types of batteries and decided on Lipo 2s. However, they come in many
different plug variants and even diff sizes.how to pick the right one and I guess something that will work
with the stock motor and stock esc, should I just wait and just take the assembled car to the hobby shop lol?
Lastly, I’ve purchased Savox sc0252 servo (read that they are decent and good value). Do you think it will be ok
for the car or should I get something else? If this is discussed somewhere on this forum, please send link!
Thank you all!
Welcome to the TT02 club
So regarding the battery question, first of all unless you have the new TBLE04S, the stock Tamiya ESCs do not have a proper voltage cutoff. Voltage cutoff is very important when using LiPO batteries as they can be damaged by discharging them too low. You can get around this with having an external LiPO alarm but your money might be better spent on a new ESC, something like the Hobbywing 1060. Back to the battery, just need to find a battery that has standard dimensions. This is typically less than 139mm in length, 25mm in height, and 45mm in width. Regarding the plug type, this can be tricky. Any battery you buy you can always get an adapter from its connector of the ESC if they do not match. Otherwise, you can always replace the battery plugs by soldering if you're comfortable, or have a hobbyshop that can help. These days I gravitate to XT60 connectors for my basic 2S, and light duty 3S stuff.
That servo should be sufficient, but it might be a bit on the slow side. It is pretty powerful, so that won't be an issue for your application. Hopefully someone with more drifting experience can chime in.
Good luck!
