yes, we are considering design of the shroud...sound advice. First design change was the seal inside stop sign. we will modify it to a 4 piece (90 degrees each), installed before the fan goes on. I strongly believe we'll see the "3 to 6 o'clock" be left off intentionally, allowing leaked air to fill chopper/discharge demand. thanks chance2/khigerd/flatfoot.
Same hardware affixing seal can be used for shroud (8 by 3/8" bolts)
