Did you test it again after that flight? You should have. You've been flying > a year and have over 300 posts here. How have you been doing so far? 1. No, I didn't test the battery afterwards. Just took it home and recharged. Realised later that of course it would have made sense to check again. Will remember next time! Thanks for your advice. 2. Although I've been a member for many months, I haven't actually been flying all that time. I am often away from home for long periods, unable to fly. Also, it seems whenever I am free to fly, the weather decides otherwise (especially winds here on UK south coast). Also, my only suitable field is a public area, so we can't fly safely when others are using it. But besides all those whinges (excuses?), regrettably this old man has to acknowledge that he has been a slow learner, spending many hours repairing . . . I have just converted to brushless with a quite powerful motor. This has proved something of a breakthrough. The extra power makes control much easier. Last evening I was flying with much more confidence, besides landing well on every occasion - no bumps, crashes or nose-overs. I am convinced the best course for newbies is to have an experienced flyer by your side. I owe a great deal to many kind guys who patiently steered me along. Thanks for your interest, and for your invariably valuable advice on SCC. |

Thats great news, glad to hear you have fitted and maidened the new power plant successfully!  John |

You might consider a simple kitchen timer if your TX doesn't have one. Then you need a decent charger or battery checker that will give you accurate voltages and capacity remaining + measure capacity input.
Using that kind of combo you time how long you flew, what the finishing voltage was, and then how many mA you put back afterward. THEN you can adjust your flying to maximize the time and not damage the battery.
Since different batteries WILL have different discharge characteristics you almost have to individualize this. An old tired 1300mA 15C will be completely different compared to a new 1300ma 30C. It also depends on HOW you fly. An aggressive flier with a heavy thumb will get different results from a flier going for long easy flights. A windy day will make you eat up more mA than a warm calm day.

Thanks for your help, John. I wish I could help you with your present difficulties. Nil illegitimi carborundum, mate. ;D |
