Don't forget you'll need at least 2 preferably 3 flight packs and 2 very solid chargers.

Also unless you have access to mains at the field you'll need at least a 1KVA generator as your car battery won't take the abuse of charging 10S 5AH packs. Even a good deep cycle battery is a waste of space for field charging a days flying.

That being said, if you set yourself up properly for electric you won't go back to glow, however I love my YS DZ170cdi and the slight smoke trail challenges me to be a better pilot on the sticks

I also hope that one day when pattern is all electric we'll be charging our batteries with a YS generator [X(]
