Default Convert GP 40 Size Mustang to Electric?

Hi All,

I am currently building the GP P-51 .40 size kit, and am considering building it as an electric. This is a sport scale P-51, and should have a final weight of about 5.5 lbs.

I have two questions for this group:

Has anyone done this that can offer any advice, either with this plane or a similar one, on construction changes to enable electric power?

What would you recommend that would give approximately the same power output as a OS 46FX? Please give details as to the exact type of motor, prop, ESC, battery, and charger (and anything else I would need). I am trying to make an informed decision about whether this is worth my while (cost wise) at this time.

Thanks,
Micky

Is $500 too much to spend on powering this plane? If it is stick with IC. I Build and fly electric .40- .60 sized warplanes. I use Maxcim motors. They cost over $300 with a gearbox. Chargers are $130+. Even nicads (the cheapest battery) will cost $150+ for two packs. I have a $150 deep cycle battery to run the charger with at the field because charging this size battery packs would kill a car battery if you want to use it to charge your packs a few times. I have a $75 charger to charge it with at home too. ......Would you like a prop and prop adapter with that? .......................................... I love electric power but in this size and power requirement it is not cheap! Yes, electrics can keep up with .40-.60 Glo engines but cost a ton more. ......................... This is the cost for your first electric. The second third and fourth ones are cheaper than glo when you consider fuel costs.

Check out my thread on the Global F4U Corsair conversion I did in "Glow to Electric Conversions." Motor and ESC cost slightly more than a quality .91 4-stroke. A pack of batteries cost about as much as a 4-gallon case of fuel.

That said, moving this to Glow to Electric...
