Hi

I had the same problem as you and for long was the only one flying electric F3A in my country. It is expensive, so the simple advise is go and look at what the top flyers in the world are using and copy that. They have for the last three years and longer done all the development so do not go and re-invent the wheel. You will get a lot of cheaper products out there but in the long run it will work you out more. Before you however decide on any product (motor, battery, controller) BE AWARE that if the dry weight of your plane before you start adding equipment is not about 2250 grams, you will not get you plane under 5000 grams by buying the lightest equipment out there (wheels axles, swithches, receivers etc). People do not always take into account the weight of those extras (servo extension leads, battery connectors, prop weight etc). Don't be fooled by claims on the weight of some electric planes and only finding out that people have to fly the planes with batteries that can hardly made on schedule. The best and lightest pack out there is the TP 5300 and according to me still the best. You do not need 25 c packs etc that come in at over 100 gram more in weight. I have made over 200 flights on TP 5300 packs (three years) and still have more than enough power to fly the P09 and F09 schedules with these packs.
