1518/1520/1717 Replacements

[Shonen]

Shonen do you give it full throttle in the air? If it's just a speed run then wouldn't drag play some part in keeping rev's down?

I can try to free rev it in the air and see what the log says, but 7.9% RPM loss sounds fairly low for aero drag on top of the drag from all 28 bearings and 21 gears. The only ceramics are in the 1717 itself, all the other bearings are either stock or Boca 99c. But yes, aero definitely does play a role in reducing top RPM, especially when it's geared for 75mph.
