Good flying weather.
It rained for several days and then stopped. The temps have been in the high 70's and light winds in the morning when I go fly. Ihaven't been bothered by the local farm animals either.
I try to fly all my planes once in a while to keep the engine/fuel system loose and ready for a contest.
I built a Pathfinder several years ago with a .51 size engine that didn't work out. I had shortened the nose 1/4 inch to compensate for the engine weight. I sold the engine and instlled the one on the plans. I hadn't flown it in several months so I took it out for loosening flights. I really like the way it flew. I don't know what happened as I don't remember it flying this well before the lay off.
I have a new way to start planes with inverted engines. I used to fuel them and turn them upside down, attached to the stooge, and start them and turn them upright. I managed to run my hand through the prop doing this. Now before fueling and hooking to the stooge I turn the plane over and run at least 3 primes through the engine. The big boys call this burping the enigne. On the very expensive engines they use they all use after run oil when putting the plane away after a session. Burping flushes the oil out. I burp the engine to warm it up a bit. If it's below 50 degreesI pre warm the engine with hot water so it will run the prime out. This puts residual fuel in the system and it's like the engine just finished a flight. I upright the plane, hook it to the stooge and fuel it. A flip of choke and it fires right up safely without having to turn the running engine over and set the plane on the ground. It's just further proof of "Perry's Law" that "Pain is an excellent teacher".
My fuel supply ws getting low so I mixed up another 5 gallon batch a week ago. After today I will start using the new batch which won't be any different than the old one. I had ordered 2 gallons from a guy but he wan't able to make the El Dorado contest due to weather so I had to got to the hobby shop and buy a gallon of the fuel I used to use in my batches. My castor oil suppplier raised his prices from 17/gallon to 27/gallon. Still a lot cheaper than getting it from Sig Mfg. Klotz synthetic oil didn't change from the last time I bought it but net time it may change. I haven't checked with my methanol supplier so I don'tknow agout that price. Flying the electric planes extend the fuel supply.
