Ok, I've stopped it from flashing the bits and pieces of the model, all I did was set my display quality from medium to high-end and the model stabilized. However the rear wing is just a straight wing without the vertical winglets on the ends. Not sure if that is correct or not, will go back to heli main page and look at the photos.
There was no duplicate folder in my community folder, I always delete the old folder before unzipping the new model into the community folder.
Thanks
