My two cents:

2.- The pipe included is for 28 engines, so I suppose it's like a 086 or a JP2 pipe, for top end, since 28's have a lot of torque.

3.- I've read that Himoto Wings are good quality. Pro-Line's Molded foams does not fit the stock wheels I think? The ones I know will fit are the Losi but I'm not sure about their quality.

4.- You listed nice servos there!

5.- Well i'm not into custom painted bodies so I just use a solid paint, but that's just me.

6.- Always use thicker oil in the front and lighter in the back, try 7-10-3
