About Me:
I hold a B.S. and M.S. AE and recently completed a Ph.D focused on Jet Propulsion. Experienced with RC aircraft since 2005. AMA member and pilot since 2007. I fly fixed wing, rotary wing, quadrotors, and everything strange in between.
Please tell us a bit about your UAV interest
Primary interest is in aircraft configuration design and exploiting AE subdisciplines to that effect. Using APM and other systems is a means of logging flight data and exploiting flight control systems to augment aircraft designs.

"Hi Aleksey, It makes a tremendous difference. At 2 cells the battery is nominally at 7.4V. A 4 cell battery doubles the voltage to 14.8V. That allows you to swing the same prop faster as long as you can provide enough current."
"Ha! Great classic show. So many interesting vehicles."
"Stephen, It's loads of fun to fly at our local AMA field. I don't think I would fly anything in a public park with people around, except maybe a small foamie or one of the smaller 20g quads. Unfortunately, we have to deal with the public sometimes…"
"Hi Gary,
We've considered doing that. Depending on the actual role, biasing the wing area can make a lot of sense. A high wing area and AR makes a lot of sense for something that needs a long loiter time at low power but not necessarily to hover.…"

"Hi Gary,
Ours also uses wings with control surfaces. And like all VTOL aircraft, we too have a high power-to-weight, and we're pushing that higher to expand our envelope. The carbon airframe shown in the image there shows the locations for the…"

"Hi Rob,
Very cool video! You can really hear the main rotor grabbing at the air.
It is true there are some ways to push the limits of conventional helicopters top speeds and one of them is to minimize the airframe blockage and therefore drag which…"

"Hi earthpatrol,
What we are bringing to market is not a weapon. It is a collection of toys and hobby racers. The design takes several cues from the military world in regard to its horizontal mode of flight, but there is nothing onboard that is…"

"FYI, here's a picture of the XFY-1 Pogo from Convair in the 1960s demonstrating low-alpha forward flight. The major problem they couldn't overcome was the VTOL part as pilots had to look over their shoulder (specifically over the bridge of their…"
"Hi Gary,
You are right that the tail-sitter concept is an old one. It goes back to the Second World War actually. The famous tailsitter program produced several prototypes, the most famous of which was of course, the XFY-1 Pogo. Where I think you…"

"Hi Bart,
I'm our test pilot on the different aircraft and I'd be happy to answer your questions.
All things being equal (so at the same power-available and power-to-weight), the QuadRKT's design offers a lower drag shape which fundamentally means a…"

"Has this been fixed yet? Is it being fixed?"
"I have an APM 2.5 in the mail headed to me at the moment. And I'm doing some more reading before it gets here and there are two things I haven't been able to find that aren't necessarily vital but would be nice:
1) A photo of a complete APM 2.5 with…"
