Default New to Electric

Returning to the hobby after a gap of nearly 10 years, and the most glaring big change to me is 'Electric Power'.

At the moment I'm flying my old IC stuff (fixed wing and helicopter), but I do find electric power very attractive in many ways (though I will morn the decline of IC in some ways).

The major thing that I find off-putting is flight time and the price of batteries. The two go hand in hand, with IC I could go down to the field with a gallon of fuel and fly all day if I wanted. With electric, I feel that my trip to the field needs at least 3 batteries and even that is only going to give me 18-30 minutes flying which is not very satisfactory - for a 550 sized helicopter, or a decent sized conventional build plane, that is over $300 of batteries, and I understand that you should factor in replacing batteries every 3 years or so.

But I think it is inevitable so trying to understand what are the popular battery sizes that can be reused in various models.

For example I have a small 450 sized electric helicopter that takes 3S 2250mAh which can also be used in the small foam sports planes.

I know if I go for a 550 sized helicopter (not certain I will) I will need 6S 5000mAh.

I have been looking at a sports plane - conventional balsa/liteply build, film covered, 60" wing and that would need a 5S 4500mAh.

It's disappointing that I would be buying so many different batteries with little reuse.

So throwing the question over to those more experienced than I - what are the sweet spot batteries that can be reused in a variety of airframes.

Cheers,

Nigel
