Hi.
First of all thanks for the comment on the video.
The retracts seem to be ok, but on the day they seem to loose air pressure so there must be a leak somewhere.
Thats why one side collapsed on landing. They wern't raised in flightbecause of the air leak. Ithought they were locked good enough for the test flight but obviously not.
I have decided after all I have been through with this model that I am going to sellthe airframewhile it is still in one bit.

Ray.
