As a general statement to produce the same power a high kv motor will spin a smaller prop faster while pulling a higher current(higher current=lower battery life) compared to a low kv motor that will spin a larger prop much slower and with a much lower current draw but at a higher volt...
But, just throwing that information into a power calculator, a 3S battery is going to spin that motor at about 15k RPM theoretically, +/- some efficiency. That comes out to over 500W. If you put in voltage of a 2S pack (10k RPM) it's more like 150W. My guess is that you have ...
Here, I will show you how I made my twin motor RC airplane with a 75in (6.25ft) wingspan. These instructions will show you the basic ideas you need to think about and do when designing and building any RC Airplane. Step 1: Find a Purpose for Your Aircraft Why do you want to build...
We can now add these known figures into Thrust Calculator. By the fact that you can verify thrust it becomes possible, to estimate the general power of the airplane in advance. This will give you more knowledge about your plane and the power characteristics to make your first flight less ...
http://www.grc.nasa.gov/WWW/K-12/airplane/cp.html Guess this should be on the science thread? Steve May 12, 2011, 12:55 PM #2559 headlessagain Reap the wild wind Thanks for you input guys. I've not changed the thrust angle since trying the new wing and ...
A good part of my life I wanted to give a hang glider a try, and as I got older that transitioned to an ultralight airplane, but I'm 71 now, and never got around to either. Maybe I wouldn't be here it I had given it a try? I used to drive by an u...
He wanted to replace an ARF airplane he shredded through a tree, and he didn't know how to fix it. After looking at what I had for sale, I asked him how bad the damage was to his plane. He stated one wing tip was broken off up to the second rib. When my mouth opened, it ...
