Default New 2 Electric

Just joined wattflyer - new to electric. I've been flying RC since @ 1985 and received my 1st electric (Stryker) this Christmas. I've flown mostly 4-cycle glow (a hand full of gassers over the years) and am really impressed with the advances in electric! I'm even considering leaving glow all together? Sure is a lot of new "stuff" to learn - almost like starting over...........

Welcome fellow Texan !

Clearly this is not your first day. I found learning about electric is alot like taking a crash course in Electrical Engineering 101 . All the things I forgot about in school.

There is some helpful nomenclature and calcs to learn but it's one of things where you can get as technical as you want or just go out and fly. I like to build and fly.

My recommendation is to read Ed Anderson's(AERJR) ebook on Electric flight. The best foundation I've come accross by a long shot : http://www.wattflyer.com/forums/showthread.php?t=31071


Alot of real experts here and a plethera of knowledge to gain from (I'm not one of them). Plus, it's a friendly atmosphere.

Good luck and have a gas ! ( well....)

I've already read Ed's article. I'm an Analytical Chemist by trade so other than advanced electronics involving Calculus (could no longer do a derivative or integral if you put a gun to my head), I'm fairly comfortable with non-advanced electronics (you start talking pnp-npn transistors and I'm lost!). The electronic part is simple math, but what prop to use or size motor for Super Sporster 120, 1/4 SIG Spacewalker is a total w.a. guess? I haven't seen any "wood" props for electric? I know nothing of motor brands (E-flite vs Rimfire vs Hacker vs OS etc.) or ESCs (Castle Creations, E-flite, OS. etc.). Are there any to just totally avoid? I'll learn.......

Chapter 4 discusses props.

Fact is the prop size recommendation usually comes from the motor MFG. Not a lot to figure out.

Size the motor, use the recommended prop.

Back in the 80s I owned an electric Sportavia. Flew gliders for a few years until one day I built and flew a glow trainer. That was a good plane but I remember the "slime".
I'm back on the hobby after 20 years and my bow is to only build electric models.
I'm glad this forum exists.

Welcome to Wattflyer.

I have a Spirit that I fly off a hi-start or a winch and sometimes on the slope. Still a pure glider. No plans to convert it.

If you are into soaring, be sure to visit the Hi performance and sailplane forum. Lots going on there.

The kadet ARF came electric ready. I had to so some figuring out to decide on motor esc batt and prop. But the AMA mag feb 2013 had an article on the kadet that
Made things easier.

The spirit is a real mod taking some effort to figure things out

Start a thread in the sailplane section and I am sure you will get plenty of help whether you are building it as a pure glider or converting to electric launch. Would make a nice ALES contest glider.

What is ALES? Come visit the sailplane forum.
http://www.wattflyer.com/forums/forumdisplay.php?f=10

This is an old blog on converting a spirit. Today we might use different components but it has some good photos.

Welcome! On the large stuff I like this one pretty well. Use the "X" style mount and these standoff's.

http://www.hobbyking.com/hobbyking/s...ffs_Gold_.html

Other sell similar ones. Or you can use ply build a box and extend from the original firewall too.

You can buy hard plastic motor standoffs at hobbylobby from 1/8 to 1 inch http://www.hobby-lobby.com/motor_mounts_287_ctg.htm . If your cheap like iam and want to make your own ,the plastic cutting boards from manards are great to cut up squares and drill holes through to make your own. Iam to cheap to pay for a couple and shipping when i can make many out of a cutting board. Hope this helps joe
