I am building a Sig Senior (not an ARF). I will covert it to a tail dragger but otherwise is will remain pretty much stock without ailerons.
I think a G-46 Turnigy would fly it just fine so I ordered one with some 5s 5000 batteries for long flight times. http://www.hobbyking.com/hobbyking/s..._46_glow_.html
Then I thought and was told that many fly with a G-60 so I went ahead and ordered one of them too. If I don't use it I will someday so it's not a big deal. http://www.hobbyking.com/hobbyking/s..._60_glow_.html
But I read on the Turnigy site that the 60 with a 13 x 8 prop will pull 47 amps and give 2850 thrust.
That should be 869.5 watts according to the math. Now that is the only prop they show it with an 18.5 pack so I donít know for sure what other props would do.
The 46 is shown best using a 15 x 8 prop and the 5S for 3150 thrust (even more) but drawing 44 amps so the draw is about the same. Math shows 814 watts.
So it appears that with the 5S batteries that I ordered I will not gain much using the 60. My Plush 60 Turnigy ESC only support a 6S pack also so I may just opt to use the 46.
At present I donít see much advantage with the other components that I have to using the 60 I have coming. I can only go to a 6S at present anyway as my battery charger is only designed for a 6 so I do have some limiting factors based on what types of batteries I can use and my charger.
Oh well, I can run some prop tests with both the 46 and the 60 on the bench on the shop and see what wattage I get on the meter.
I guess it's time to see what the watt meter shows on the bench with the two motors and some different props.
Lessons learned I guess.
