Good advice from the prior posts, but it may be helpful if we knew how you intend/prefer to run your cars....as there are variables that come into play and they can be meaningful.....eg., do you run on plastic/wood tracks?, are the wood tracks tape/braid/magnetic braid?, is your track(s) tight and twisty, or open and fast?,what rules does you club have/not have?
In Europe, the favoured RTR set-up is anglewinder...based on the fact that most big events are run on plastic track (steel rails), and although the vast majority of races do not allow traditional traction magnets, the magnetic effect of the big magnets in the FK 180 type motors (some can generate 60gms of downforce or more), far outweighs any inherent issues with running an anglewinder. Additionally, the high torque levels offered by the FK180 type motors (longer stacks/bigger magnets) really help drag these cars along a steel track rail. Chassis set-up in this case rewards a very soft longitudinally flexing chassis, as the magnetic effect of the motor will cause the chassis to further bend towards the track, further increasing downforce. (it is very common in European events to see motor labels worn off/scratches in the can.
So, if this resembles what you/your club favours, an anglewinder is the way to go
The majority of my racing is done on wood tracks with either tape or non magnetic braid, so, like the above gentlemen, I favour a sidewinder set up.....it provides the most mechanically efficient gear orientation, has less "moment of inertia", and with the current "S" can motor choices, you will be able to power up to any degree you need. The lighter weight of the "S" or "130" motors, allows you to "weight" the car to your tracks/cars needs while still coming in at less overall weight than a similarly weight tuned AW. While the higher torque of the FK 180's can be argued to be an advantage on some tracks, the same effect can be closely achieved via gearing changes on an "S" can. Most (all) of the cars involved in "serious" high end wood track racing, incorporate a sidewinder set-up, and the lightest motors possible.
Both motor orientations have their place........where and how you race will dictate the most advantageous set-up.
