Thanks a lot for the info. I think I'll use the 12" rule when possible and convenient. Also will use PCM and high quality, never crashed quality electronic parts. I have an Aeroworks 27% Ultimate that I'm going to power with a Brison 3.2, and a BME 30% Edge that I'm going to power with a Brison 4.2. I'm new to gassers and really appreciate the assistance. More questions to come, I'm sure.
