For this plane, I used 2 motors that would provide roughly 860g of thrust with a 10x4.7 propeller (1720g total) and draw about 12Amps each.(Info/ Recommended propeller found on motor manufacturers website). Using this equation,(Flight Time(min)=Battery Capacity(Ah)/Motor Amp Draw(Amperes...
The final motor setup is a trade off between efficiency and battery size. I highly recommend using a motor calculator to find the performance of the motor prior to buying it. Ecalc is a easy to use subscription web app that contains many motors and propellers and allows you to essentially ...
Kyosho P-51D Mustang M24 RC Electric Airplane RTF The first of the new Kyosho "Backyard Flyer Series!" Built to such exacting detail, it's easy to forget the Mustang's 1/14 scale compact size. Look inside the canopy to see the detailed pilot and minute parts that give this plane that...
sketch = sketches.add(xyPlane) points = adsk.core.ObjectCollection.create() # Create an object collection for the points. # Enter variables here. E.g. E = 50 startRange = 0 # Start of range to be evaluated. endRange = 2*math.pi # End of range to be evaluated. ...
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 ...
When we move to a higher elevation, the air density decreases as we saw earlier. Since the weight of the plane, the lift coefficient, and the wing area all stay the same, V must increase ifρdecreases. Specifically, V2must be divided byρ, and hence, V must be divided by the square...
The calculator app I used estimated the level flight RPM around 15,000 with that load, however, other factors could have caused the motor to over-rev the prop - prop stalling where there's no air for the prop to grab, and dives under power that would increase airspeed would also reduce...
Discussion Big Prop / Motor setup for WW1 bi-plane Hi.. 1/4 scale SE5a (WW1 bi-plane) 80 in span- weight with gas burner around 17 Lbs Scale Prop diameter is around 24 in. Would be nice to find a scale like board-bladed wooden prop with rather high pitch and find a VERY slo...
DeadstickDuck Electric Barely 1:1 on 7s9000 on my stock 6s motor. I had been flying all last year on 8s8400 of the older P42A cells and I really like these new updated P45B. They are giving me above 81% capacity running full power until 2.9v cut-off. Going a bit easier like ...
