I intend to get a MP777 with the following:

1) Futaba 3PM
2) 2 x s9203 high speed servo
3) VZ-B v-spec

What battery pack should I get for the receiver and what tuned pipe and muffler would be suited for the above engine? I was considering the JP2.

Is there any additional items I need to make this package complete. I’m currently in Mongolia and there is no hobby shop within close proximity. Therefore, I want to make sure I get everything I need at once.
