I own my very own dust cropper and realized that there was something funny acting about it. I had to check the problem out and realized the propellers of the aircraft were sticking, which is a very bad thing when flying any kind of aircraft. I had to get my hands on some nonstick coating that would lubricate the metals of the aircraft, specifically the propellers at this time. I just knew that I would more than likely have to go online to check out the product I would need to buy for my aircraft. I found a product that was very promising and ordered it. I applied the lubricant to the metals of the aircraft, especially the propellers. I found out that the propellers of the aircraft starting working and spinning very well with the nonstick coating that I applied on the metals of the aircraft. I am happy with my decision.
