I had a very strange thing happen today. I took my Razzle 3-D plane to the field this morning, the temperature was 4 degrees with
a -15 wind chill. After getting it started and warmed up I taxied out, lined up, took off full power and a slow climb, it quickly dropped
it's nose and when I countered the movement with some up elevator the wing folded up on the left side. The wing pulled off and the
plane went in with no power as I had shut it down as soon as the left wing fell off. Needless to say, it's a total loss except for the engine
and gear. I usually take off and go vertical off the deck but I didn't today cause I wasn't sure she was gonna stay running.
The wing was a one piece design with no known damage. I have had the plane for a number of months and have owned it since new.
I did have a tail in accident with it two months ago and had to fix the fuselage, lost it close to the ground on a harrier landing attempt.
It had no visible damage to the wing. I was just curious if the extreme cold temperature could have had anything to do with it?
This is the coldest I have ever flown a plane in or a heli for that matter and not sure what caused it to fold up. I have had no flight or
performance issues with this plane till now and have always tried to throttle back on nose down manuevers just like on the giant scale
planes to not over stress the airframe. It has an OS 91 FS and a 15x6 prop.
This is the start of my third year of flying and I have never folded a wing on anything, even my 1/4 scale Edge 540 when i didn't throttle back on dive's.
Thanks for any idea's or theories you may have.
