I'm considering a Kyosho Turbo Optima purchase, after discovering it's existence many years after my dream of owning an original Optima. I'm overwhelmed with the choice of motor/battery combinations available, and am looking for some advice. I will be purchasing and building for pleasure only, and have no intentions of racing it. I'm not interested in maximum speed as much as I am getting a decent run time from the motor/battery combination. I would also like to stick with Kyosho if possible. Any advice would be appreciated.
