I'm new to Nitro and I have a mint condition duratrax street force it looks like it just came of the shelf. The only thing is the velocity.15 It runs threw fuel in minutes and that's just at idle. I was thinking of getting a new motor just to break it in and know how the settings are just to get a feel for it. You know what it likes and what the motor dislikes.
What I need are some recommendations on size,reliability, tune-ability, and speed.
Any help out there would be awesome.
