"Good stuff. Thanks for the update."
"Hi Forrest,
Great work and thanks for sharing.
How are you getting on with registering this with the Guinness World Records?
Do you have the final endurance figures for the flights out of ground effect?
Cheers,
Stephen."

"Chris, I have done a comprehensive review of available filters on my blog which I am happy for you to use: http://blog.soton.ac.uk/robotics/projects/new-halo-uav/low-pass-fil..."
"Mohamed, thank you for your comment. There are always compromises to be made. We try to realize the largest props (for efficiency) with the most compact size in terms of diameter and height, and also minimum mass for max endurance. So far we are…"
"Hi Josh, we have used linear polarized base station antennae successfully. However, they can be large and heavy for high gain. We definitely have multi path when operating in urban environments and also when operating over long range and at high…"
"Chris,
In the overview you mention 1.3 MHz, I guess you mean 1.3 GHz. Also note that the units should always be MHz or GHz (capital H for Hertz) and always a space between the number and the unit.
You might want to mention filters, antennas and…"

"No, though I understand that this could be advantageous. The CF props that we use only come in certain configurations. Variable-Pitch multirotors have been used by various researchers in the recent past. They have clear advantages in terms of…"
"I should state that we have tested circularly polarised antennae at 5.8 GHz, however they have limited gain and at 1280 MHz (legal US VTX Frequency) are rather large. Remember, that we were trying to transmit over a distance of 2 miles (3.2 km)."
"We use an 7 dBi big stick omnidirectional antenna for the VTX on the UAV and a Yagi for the GCS. The choice was mainly based on mass and gain. Thanks for the tip, if you know of any that are less than 50 g let me know."
