Well, for now I just charged up a 1000mAh and three 800mAh 3S battery packs. The flying weight was nine ounces with the 800Mah packs and 9¾ ounces for the 1000mAh pack. I was afraid it’d be a dog, but the plane flew okay for roundy-roundy flight. I didn’t try to see what it’d do for loops and such. I just had my son launch for me and I did three or four laps to make sure it’d fly, then turned the plane over to him. I forgot to put Velcro on one of the 800mAh packs, so we only did three flights on the plane. I’ll charge the batteries back up in a few minutes and I’ll see how much we took out of them. He only flew between 3½ and 4 minutes on each flight. The motor was cool, the ESC was cool, and the batteries were not quite warm. So, they are not being taxed in any way
Dennis, I was hoping you’d chime in. I’m not one for sending things back. Not that I’m shy about making noise. More that I’m of the temperament of, “I WILL make this work!” If I can’t make this work, then I’ll send it back. I have at least one APC 6x4, I think. I’ll work that into my tests.
Traian, I did the 3S for today, but I’ll try the 2S next week with some tweaks.
Target, I have some 6x3, 6x4, and 5xsomething props I can try.
John, I’ll try different things and probably make myself a chart for prop vs. speed vs. power. I do have a servo tester, so I can probably work that into my testing somehow.
Keith, thanks for the info on the APC 7x5SF prop. I guess at the RPM I’m getting, a Slow Flyer prop would be okay. I picked up a couple at the hobby shop today, and I’ll give them a try. Since the 6x5.5 isn’t taxing the system, the 7x5 shouldn’t load it down much more. 35’ Spectra is what we’re flying on. I never thought of the white card to check no load speeds. I’ll have to make up a disc and give that a try. I picked up a couple of new 800mAh packs at the hobby shop also so I can do the testing with what are hopefully two known good battery packs.
Thanks for all the help, Guys.
