Pop out floats on a 206BIII by Mike Th...
We operate floats on all our Jetrangers and our 407. For a 206BIII, I think the weight difference compared to high skids is about 75lbs. As for an effect on airspeed I'm not so sure because I'm on the maintenance side of the company. Yet I figure 5-10 knots. If you want some precise numbers I...

Tuned exhaust for the Lycoming 0320 by Stuart & Kathryn Fields
I'm just having more fun than should be legal and it probably isn't if I look far enough into the County, State and Federal statues, but I am never-the-less. I have pretty much followed the Cafe numbers for header length and the 4-into-one collector. Keeping in mind friendship to my...

UBC's Human-Powered Helicopter blades questions (kinda technical,engineers welcome) by james cho
Here's a pic of their blades layout: http://batman.mech.ubc.ca/~hph/thunderbirddesign.gif (note the blade rotation arrows) What I'm wondering about the blades: - Why the odd taper? I'm guessing the taper alleviates tip losses, but why does it begin at the ~.6 span mark? I'd expect taper across...

Vortex by Stephen Austin
Which basically amounts to the same thing, doesn't it? You're still going to have to have sufficient altitude to nose over to gain airspeed either way or can you recover more easily once the VRS is halted and the rotor blades are flying in relatively clean air again? Hmm, no, not really. ...

Why do gyros use tilt head rather than swashplate by Phillip
Would a gyro with a swashplate ( just for pitch control) fly any different (better,worse) than using a tilt type rotor head? Just more complex? Also, I've seen some photos of early kit helicopters that appear to have just a tilting head (no way to auto-rotate ?). Isn't this a bit of a death wish?...
