After MANY months of building my Goldberg Eaglet 50 and converting it to electric power, I'm down to covering it and doing the detail work.

So far I've purchased a E-flite 25 motor, a 70 ESC, a 6 channel Futuba, fabricated flaps and alierons, and 2 1/4" wheels.

I decided to weigh it last night (and laid the two monocote rolls on top of it) with all the servos, the reciever, receiver battery, wheels windows, motor, ESC, (basically everything that will be in the airplane) etc. It weighed 70 oz and that doesn't include a 4800 mv battery (which I looked up and weighs about 16 oz) . The box says it should weigh no more than 40 to 50 oz.

Am I in trouble with that total weight?

Can the 4800 mv battery also be used to power the receiver? If I could eliminate the receiver batter it might save a few oz.
