Hello everyone would like to start out by saying that I purchased a Destiny flying machine this June and absolutely love flying it. The jetting is perfect for the summer MN temps around here 75-80 degrees. I would like to convert the jetting so I can safely fly in the winter temps of 20-25 degrees. My question is do I have to change the needle jet and the Main jet? IF so by how much? would anyone have a chart that I would be able to look up what size jets I should order. Thanks and any help is much appreciated. PS I am at 1100FT
