"Very elegant design. How do you prevent a nacelle or ground propeller strike when powering off the front motors after landing or an aborted take off?"
"Looks really nice. Think about getting that pitot tube in clean air for best performance. You may experience issues from turbulent air generated from the nose of the aircraft when yawing left. Generally the pitot tube is either placed ahead of the…"
Few questions:
Is there a plan to keep the aircraft from drifting into an area that prevents taking off, i.e. tree cover, rocks, a river?
How do you intend to integrate the solar cells…"
"Brilliant design, I love the hybrid concept that bridges the gap. How are the flight characteristics with varying payloads? Because your payload bay seems far forward of the CG, I'd imagine you may experience issues with different weight payloads.…"
"I'd love to see a solar assisted variant that drops the package and returns to home. The night time variant could carry a non-solar wing, more batteries, and nav lights."
"Great work and a novel approach! Have you tried larger control surfaces or large vertical control surfaces on centerline to aerodynamically counter torque? Curious if that would allow you to ditch the anti-torque motors, lighten up the load and…"
"Fantastic work! The continuous milestones this project keeps on achieving always amazes me. Would you be kind enough to share any detailed information about the MPPT? Thank you."
"Look here for modified Zenoah motors claiming use for UAV. Again, afraid to run "tuned" motors in a professional application. I'd prefer a heavier more efficient motor running happily at constant power than a tuned, bored, ported, stuffed crank,…"
"Rob, I highly recommend giving RCV Engines a call. They're located in the UK and have been making quite impressive motors for a very long time. I used to sell their rotarys and compact 4 stroke nitro motors some time ago and was very impressed…"
"The problem with a hobby RC engines is the low service life and high service interval. Yes they produce a ton of power but efficiency and reliability are generally the desired traits of UAV engines. They're intended to be used a couple of hours…"
"It's a nice looking craft, don't get me wrong, but I believe your introduction is either premature or presented with blind ignorance. Many....most of the UAS startups that come and eventually go are guided by driven and very smart people. The…"
"Looks really nice. My main concern is the small contact surface area between the boom arm and the aluminum mating flange that the nut screws over to secure. I'm afraid that under load and vibration, over time that may separate causing a major…"
