I did in fact hooked everything up to test it before the flight and was runing on the ground for a few minutes.
The winds were down the runway and we were doing left hand patterns, this crash happened on the downwind turn about 80 degrees of turn into it.
And my confidence was slow with this bird because on the first flight, i only had two circuts and it got Radio hits every circut in the same place so i decided to land.
Though a recent look showed that the screws connecting the alunimum servo arms to the servos on the left wing was not there on the inner servo and was very loose on the outer servo. My assumption is that maybe the arm got stuck and made for full left aileron. I was on low Rates on it for a while so It had a lot more throw than the other wing.
The engine might be o.k. so Its going to be sent to DA to see if they can fix it or what not.
thanks,
TJ

Status: offline 		another thing is that Wind does produce lift.. its your wing's airfoil. The shape of the wing depends weather it makes lift with wind, or just raw power. Aerobatic planes like mine have semetrical airfoils which make it a smoother flight and great for stunts,..for heavier planes they have a larger curve on the top to produce lift. This helps it get up in the sky.

Status: offline 		wind shear is an aircraft low and slow on approach as the the aircraft enters the shear which is really a down draft its pushed down the aircraft//pilot doesn't have enough room or speed to 1 power out or 2 manuver out that's the very short version of a shear... after fixin em for 30 yrs and flying as crew for 20 yrs I think I have some real knowledge

Status: offline 		again,
the winds were pretty strong about 15-20 maybe gusts to a little more maybe, It was actually a little over normal, But I was determined to try fly it once and I needed to get my thumbs back from 4 weeks of not flying it
If youd ask anyone at the field, the normal winds are around 10 knots, gusting to 15.

AMEN to that, i was flying down wind at about 40mph in a 50mph wind and the elevator became useless......... we all know what happend next.

rcpilotcd


That would make your airspeed exactly 90 MPH. Elevators probably became useless because your servos weren't strong enough to drive them. And who flies in a 50 mph wind?

Status: offline 		Well I think wind does affect planes cause when i am flying and pass wind my planes do incredible stuff. I think it affects the other flyers also they tend to move. Beyond my apprehinsion(close as I could get to spelling that big word lol) But that is also gale force wind of 50nots. I know it's got a K just messing around.

Status: offline 		your airspeed is 40 your wind speed is 50 and because you are traveling down wind your ground speed is 90. if you were going up wind your ground speed will be -10 or backwards. If you were traveling cross wind your ground speed will be roughly 40 given no crab into or out of the wind. But in all of these situations your plane will be traveling 40 mph airspeed. The plane if trimmed for level flight will continue to fly level no matter which way it is pointed because it will always try to return that state of level flight. If you turn suddenly into the wind after traveling down wind at a faster ground speed the plane may climb a little as it slows back down to a relative 40 mph but once it dows slow down and given no change in power setting it will fly level again. Given the above speed example though it will be going backwards as viewed from the ground but it wont matter because relative to the air mass it is in, it is traveling 40mph airspeed.

Status: offline 		I've just started flying helicopters, and from what I have been told and experienced, wind does effect lift.

From what I've been told, the rotating blades of a helicopter provide lift similar to a wing on an aircraft. When I am hovering, with no change in any control, my helicopter will often climb or fall quite a few feet, in gusty conditions. This does not happen in dead air. So the gusts of wind seem to provide extra lift, and when the gust dies down, the extra lift disappears.

Status: offline 		Man that pavement has no mercy.Hope you get it all cleared up.

I dont get this wind thing either.
My foamy I can fly into strong wind at 20% power to stay aloft just above wing stall.Sometimes it has some groundspeed ,sometimes it flies back a little ,depending on wind velocity
If I turn downwind I must run at 80% power to stay aloft,just above stall.I assume I must fly just a little faster then the wind is travelling in order to get lift.Of course now groundspeed is very fast.To me wind seems to make a huge difference in lift.If you are low on power,downwind travels can be difficult or impossible.

"At 2100 rpm the DA-20 does 90 kts when trimmed to 2 notches above center. it does that in a 10 kt headwind, still conditions, a 5 kt cross wind, or a 20 kt tail wind. "

Mate, I know this might be rude.. but are you on drugs? You're trying to tell us that an RC plane flying with a constant throttle setting into 20kt HEADWIND flies at the same speed DOWNWIND or in STILL conditions?

LMAO... I think we all know this is CR@P! :P~ Sorry... but it is. Period. :P~
