Cheesehead-RCU,

You asked about "high/Low".

Most manufacturers tune thier receivers to the middle of the band, approxchannel 35, or 36. You put in a crystal and fly. Futaba tunes some to the middle of the lower half of the band, approx 23, and the rest to the middle of the upper half of the band, approx. 47. With these, you have a better chance that the crystal you use is closer to the tunning of the electronics than with the other brands.

When you send your set in for maintenance, you can have the receiver tuned to the same channel as your crystal. Supposedly that is even better.
