Ren,

While John Kagan can get away with not talking to anyone, as a non-world-class flier, you probably should not follow the same path.

I constantly compare notes with other fliers. Winding torque, launch torque, motor sizes, lengths, weights, turns put in -- these are absolutely critical items. By comparing notes with other fliers, I become a better flier.

I highly recommend that you calibrate your torque meter.
