Here are 2 of my newest projects:
First is an original GT. Just finished this today, just need a battery strap setup.
Reedy 3300kv, sc500 BL ESC, 3s 30c hobby people, T4 modified motor plate, stock GT transmission, XP3 radio, just about every single part is RPM. Weight is 1646 grams with the battery.

I'm not anal, they still have the Nitro grime on them haha
Here is a GT2rs of mine

I gave the GT the Reedy setup and have since gone with a 3s castle setup.
