Hey guys I'm new back into the sport of flying. Waaaay back in the day it was a short period with gas planes out at the TooRock naval station and then several years with thermal gliders off of Sonoma mountain. But I got too into it and was spending way too much money (for what I was making at the time) and got out of the sport about the same time I got married! Well now jump forward 25+ years and I have some money to spend and a 9yr old of my own to do this with (helps justify with the wife )
So I'm wanting to learn about electric motors and prop selection and don't want to always ask what set up for what plane. So I picked up a hobby king watt meter but it is really lacking in directions. Can someone help point me in the right direction to learn more about what to look for and what it all means?
Here is a test I just did with GT 2215/09 1150kv motor, 30A ESC, Gens aco 3S1p 2200 25C battery.
Results,
12x3.8 SF prop (way to big) 35A, 360W
10x4.7 SF prop 25A, 295W
9x4.7 SF prop 17.9A, 212W
This is on my tweaked version of an Edge 540 and yesterday I maidened it on a 7-1/2min flight 1/2-3/4 throttle most of the time with a few full bursts. Motor and ESC felt warm but not hot and the battery still hade 11.2V after and this was with the 10x4.7 prop. This has an 810g fly weight.
So what does all this mean and for 3D flying is their a better set up for this plain? I was very happy with the results but also I don't know any different!
Thank you in advance for any help or pointers you might have.
