Title: Re: DroneAcharya DA-01 (Foam & Corrugated board Build) Post by: lastRites on May 30, 2015, 09:21:05 PM On second thoughts, is that wing a bit skewed? Did you perform glide tests? And the electronics setup seems a bit odd. 30A ESC and 4s on a cd rom motor, plus the weird prop..

It may cause the plane to roll unstably... Title: Re: DroneAcharya DA-01 (Foam & Corrugated board Build) Post by: DroneAcharya on June 01, 2015, 08:08:08 PM Thx for the suggestions and advice friends.. Yes I noticed the wing was skewed a bit as well but it wasn't so until I painted it. I think the corrugated board absorbed the paint unevenly or some other issue.. Next time I will stick to foamboard or sunpack for the wing..
Have also modded the wing as pic attached.. Will be flying it this weekend and will post a video soon. Cheerz.. Title: Re: DroneAcharya DA-01 (Foam & Corrugated board Build) Post by: topalle on June 01, 2015, 10:05:23 PM corrugated board does not absorb paint...
there must be some weight distribution issue add some weight on one sideand keep for some time (few hours). remove the weight and then check |
