I'll start by saying that I have not flown a 182 model glow nor electric. But if you want to start thinking about it just follow some simple steps.

1. Lets look at the Hangar 9 182 (40 sized) The specs are: wingspan 66", area 579 sq. in, and the listed weight 6.6 lbs. Subtracting the expected weight of the engine, fuel tank, throttle servo, lighter servos (note I didn't say weaker) I'd guess that the "empty weight" or the weight before we put in the motor package would be 5.0 lbs.

2. Lets go to Motorcalc and play with some power systems. It can get tough picking through the many choices so lets "fix" some of the varibles so lets look at the AXI series of motors and GP3300 cells.

3.I look for setups that give me at least 70 watts/lbs. I see that 14 to 16 cells with a 11-7 to 11-8 prop will do nicely. The wing loading is high at 30 oz/sq in but I coulf fix that at a price by going li poly.

4. Using an AXI 2820/10, a 4s4p TP Lipoly battery and a 11-9 prop we could get 85 watts per lb and a wing loading of 27 oz/sq in.

In a nut shell, it would be very doable project.
