Why is the Sidewinder SCT BEC 5V?

[kazuaki]

Just wondering why this is 5V. My standard Sidewinder is 5.67V and the new SCT version is 5.0V. Unfortunately, the lower output doesn't work with the stock servo on my SC10 brushless, which happens to be a HV unit that expects at least 6.0V. Needless to say, the steering is terrible. It work OK with the older Sidewinder. Will there be any firmware available to alter this output, or do I have to swap to a different servo?

Thanks
