Bosch232--What I mean is this..Let's say you can walk 100' away from you plane with the engine off before any glitching or lock out. Then with the engine on and varying RPM's you can only walk 50'. That is not acceptable, you should be able to walk at least 85', some people say no less than 90% or 90'.

As for mounting,, I always hard mount them and have never used any type of soft mount.
