Yeah, that's a plus not having failures while flying. On all of my helicopters I used oil commonly for gun lube. It's called "Snake Oil" and by using it on all of the bearing surfaces it almost doubled fly time. It's a derivative of the lubricant used in high speed medical drills and cutters. One of its uses is in air turbine dental drills.. The film affinity is 2years, doesn't attract dirt or contaminants, or contain evaporants..Kind of pricey, the shipping is more than the product. Bottom line, longer fly time and no burnouts is my goal. Did you only cut away the shrink wrap where the heat sync was attached?

Good to know about the snake oil, thanks. I cut out about 2/3 of the size of the esc's heat sink to make sure there was still enough to hold it together, that way it to got better cooling period even without the extra one.

If you will double a piece of Aluminum foil and place it between the ESC and the heat sink , press them together where the wrap was removed and zip tie it will solve the heating problem all together. I flew the last 3 wks in temps between 108 and 117 out here in West Texas..about 1/2 or 3/4 wide open with a 30 ESC...no problems at all!! chas ps I did not have to use any of that messy metal paste!!

Here is a good video on the subject:

I assume you had initially a 7" 2 bladed prop and decided to use a 6" 3 bladed setup.

Two things to take a look at is with the reduction of dia, you need to take a look at the fuse blockage. If there is too much blockage of airflow, you might lose the efficiency of your prop.
Secondly, with the higher drag and smaller blade dia, your landing speed will increase, so be aware of that. That was not covered in the video. APC data from wind tunnel info backs that up. The reason 3 and 4 bladed props were used is to have ground clearance on takeoff and landing.
I like to design and fly unique planes.
