RE: Lightning Build
The all up weight with a Hacker C50 14XL, Hacker Spin 99 ESC, Power Unlimited 4900 batteries, and a 900 mAh receiver battery was 4612 grams as the NATs. This weight is also with an APC prop and a Tru turn spinner, which are not the lightest equipment. The key to making this kind of weight is to not allow and piece of wood that is not the lightest into the airplane. I weighed each part that went into my airplane. Out of all the wood I ordered, the difference between the two heaviest fuselage side sheets and the lightest fuselage side sheet was 3 ounces. Saving a gram here and there really adds up in the end.
As far as electric set ups, there are many good setups. If you are new to it, I would use a proven combination. There are quite a few threads dedicated to electric set-ups on this forum.
