At the field nice sunny day. A friend puts together his Extra 300, checks the batteries usual preflight. We go out get it started running great. I ask if he check the surfaces for proper direction hes says "Yep" Taxis out nice takeoff plane begins a nice roll to the left.then impacts. The whole time he's saying "I'm holding right" Post impact inspection. Didn't plug in the airlerons. Moral of the story. When you asked "everything going the right direction" be sure and look at everything. I guess rudder could have saved it but never even thought to try happened too fast. Shame too he just got it trimmed and flying great.

i hate it for him

That stinks! I am always affraid that this very thing will happen to me, and it probably will.

It is a damn shame that practically everything learned in RC is learned the hard way..

That does stink. That's why I "wag" (and watch) all the control surfaces just before EVERY take off. yup, yup, yup...ok lets go...It's a little ritual now. Saved me from the ailerons plugged in the wrong channel.

I was taught to check EVERYTHING. Up, Down, Left Aileron, etc... OK, let's fly! Bummer of a crash.

Me too. As I taxi out I always check movement "one more time". It funny as time goes on and we become "more comfortable" with a plane we may go through the motions but not notice whats going on.
I learned from a friend's mistake. Hope maybe this saves some one else from the same.

Sorry to see that happen. While I'm assembling the airplane, I take an extra two minutes to turn on the radio and see that everything works as it should and it moves in the proper direction. Once the engine is started, I hold the airplane and check again.

I find that whenever I get out of my "normal routine" of plane assy at the field / preflight check, there's going to be something go araie. Examples of this would include bs'ing with my club buds, etc.

I had one of my friend's kids come over one time and I ended up focusing on him instead of my plane. In the control surface check, I'd discovered that I didn't hook up my ailerons. BUT - I caught it.

Whenever I get out of the normal routine now, I just put everything down and wait till the "normal routine" presents its self (comes back), and I'm able to focus on the plane / radio.

yep, check them all just before take off.

just like in the real planes, check every surface before take off.

Welp: It looks as if it took a pretty good thump'in, but I don't see anything that can't be fixed. What I'd do is put it back together make the repair covering different nasty colors so that I had a blunt visual reminder of how it got in that condition to start with, and then see what else it had to teach me.

But that's just me.
