SteveM | 25-Feb-11 21:59 | It took two weeks for the motor wire I ordered to go to my old address 80 miles away before finding its way to me. Of course that wasn't till I gave up and ordered more wire from somewhere else only to have them both arrive in the mail today. Anyhow, all of the electroncs tested out fine. |
pfinn | 26-Feb-11 10:34 | Hi Steve. This looks great. I love this aircraft. Please don't take any offence, but are you sure the Pixie ESC is enough? The recommended 25 amp does sound like overkill but don't you think the Pixie 7 just might be cutting it a little close? As everything heats up during flight doesn't the amp draw also increase? It would be an absolute shame if something "Adverse" happened to this aircraft. Sincerely. Phil |
SteveM | 26-Feb-11 11:36 | Phil, not a problem, I can use all the brains I can get. About 11 months ago (has it really been that long?) I tested each motor at full throttle from a battery at 50% charge and measured 2.75A per motor for a total of 5.5A. Of course if I changed the prop or remeasured with a fully charged battery I could easily break the 7A limit of the Pixie-7P. The Pixie-20P is now discontinued so if I need to I'll have to find a used one or run two of the Pixie-7P ESCs. Before she maidens I'll be sure to perform a full check. |
