I have delta 15 engine... don't know if it's good though . i'm new in r/c. I tryied many times to setup my engine so it can go fast (as my frinds r/c that have the same engine as me...) but nothing happens.. either it won't start at all or it will go slow.. i went to a shop to setup the engine but he didn't do much.... so plz anyone knows how to setup properly the delta 15 engine?
thanX for the time
