Here is a great match up for Digital racing! The alpha chassis Flyslot 512 motor is almost a perfect rpm match for the Carrera e200. Lap times on my track are within tenths of a second. The other 917's are due in today, and will be chipped as well. Hoping to get a full series of these by the 21st for our next 2.4 Lemans race. It took a little tuning to get the fly to run with the Carrera 917, but not a lot. PG rear tires helped the most, and a set of bronze rear axle bushings to get rid of the binding. smooth and fast now!
