Armody,

Why are you going to reduce nitro for summer flying? Is it a cost thing?

FYI. Higher nitro buys quite a bit in the heat of the summer when air is thinner due to heat and humidity, both of which reduce the available oxygen the engine needs. If you are flying trainers it won't matter that much. But when you start flying higher performance planes it makes a considerable difference

Do run the engine dry after every flying session. If you use brass tubing in your tank, make sure you don't store fuel in it long term. Brass and methanol will react over time and will generate acetic acid (vinegar). This acid is responsible for corrosion in your engines. If you have ever taken a tank apart after it's laid up for a year, you can smell the vinegar. BTW, it's a good idea to open thetank after every couple years and replace the silicone rubber line to the clunk...inspect the brass tubing for greenish residue. If you see any, replace the brass. Use plastic tubing if possible. Nylon or polyethylene are great to use in the tank

If you are not going flying for a few weeks, it's a good idea to use after run oil in the engine. I use good ol castor oil when I store my engines for the winter. About 10 drops is all it takes. Turn the prop to distribute. Another great after run oil is Marvel Mystery Oil
