Careful!
Preflight - Preflight - Preflight

So what happens when you do your preflight check on a new plane 3 times prior to it's first flight and you still end up flying with an improper control? You crash!

I checked my surfaces no less than 3 times yesterday prior to a maiden of a new scratch build and somehow I failed to notice the elevator was reversed.

Needless to say the result was fatal to the plane.

happens to the best of us. Seen a guy using a gyro and it wouldn't roll off, the gyro was backwards, so he flip it to reverse, guess what, it fixed the gyro, but reversed the stab movement. totaled.

It was a handlaunch plane, right? I'd find it hard to get into fatal-crash-altitude without a working elevator...

I used to fly full size gliders and when I started the instructors made everyone check the controls every time before launch.
I had just flown this glider so I asked why you had to check something you had just flown and I hadn't even got out of yet as you always had 3 flights.
He said if you check everytime no matter what then you will never forget to do it.
Always a good idea to get someone else to give it a second look as they are not running on adrenalin and can think a bit better, lol.

It was, with this one the preferred launching method is to hold from the top of the fuse just behind the canopy, point upwards throttle up and just let it climb out of your hand. So 2 seconds it's 30 - 40 feet up.

I know at one time or another we've all done it/will do it what have you. I'm just trying to save at least 1 newbie from the mistake.

i did it with a b-17 bomber, ground launch, i had the ailerons reversed, was the maiden flight, was so excited i forgot the preflight... i only tore one of the engines off.

My preflights are quite extensive these days =)

I was flying a borrowed EPP 48" Yak at a RC event - owner trusted me enough... it was EPP and over a grassy field, he was fine with it.

Took off, but quickly realized the plane was handling "funny". "Funny" quickly turned into "uncontrollable" and was juuusttt barely able to make a semi-safe landing, but did break a prop.

The rubber band wing joiner had degraded and snapped inside the fuselage, and the wings were largely loose and falling off when I was taxiing the plane back.

As mentioned above, while flying full size sailplanes I checked everything every time I was in pre launch (winch launch) mode.

CISTRS controls, insturments, spoilers, trim, release (winch line), straps.

That was about 45 yrs ago and I could still do that cockpit check in my sleep. Do I have something for my RC sailplanes? HELL NO!!! Have I crashed? HELL YES!! Stupid? HELL YES!!

Fully agree on the need to do preflight check before every takeoff. And it needs to be a test (think what you are doing and observe the results), not just wiggle the sticks and hear some servo whirring.

Another good tip from full-size maintanence world: you are blind to your own mistakes. If you do something to a plane, get someone else to check it.
