"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…"
"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.…"
"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…"
"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…"
