Electrics
 

Hello all,

I have ordered a small Extra 10 kit that I wish to be electric powered.

How do I go about calculating what size/ type of motor, Esc, battery pack etc, to drive this model.

So far I have all glow fuel engines, but thought an electric model would be fun.

If anybody can set me in the right direction, I would be most greatful.

Many thanks,

Sidekick

Then read as much as you can from the Electric forums on this site, and visit the biggest electric R/C plane forum site on the web: the E-Zone

I was going to recommend essentially the same things.

The guys at Ezone are virtually all electric flyers. Just don't mention you're a "slimer" (glow flyer), or you might be shunned. ;) I found that in spite of electric flyers calling glow guys 'snobs', they are about as elitist as it gets. (I fly electrics too, so I don't feel too bad saying it.)

They will tell you that the first rule of electrics is, decide on the power system first, then buy/build a plane to suit those characteristics. It's easier than matching the power to the plane.

What AUW (All Up Weight)/wingspan are you talking about? Those will be critical to your choices. And you can figure the power system and flight pack to be about half your flying weight. (Small servos and receiver for anything under about 4 pounds.)

You can fly up to about 20 ounces AUW with a speed 400 motor DD (direct drive), and add another 4 or so ounces if you get a gearbox for the 400. Of course this all depends on the type of plane. In your case I'd stay under those weights as much as possible if you want aerobatic performance.

Anyway, sorry for rambling. Electrics are a different type of fun, and you need good advice or you'll be disappointed.
