Thanks, Mike, great post. Are you *sure* that cheap lil HF thingee is a float? I'll go check... I'm such a cynic... GeoB

Since it is all made in China anyway, might as well get the 1 amp trickle charger from harbor Freight for $6 on sale. Gets the job done just as well. GeoB

I work in an IT dept, and sometimes the old batteries get passed around. I think that many of them will have life left even if they don't perform. I think many of them need de-sulfating. I have a couple desulfator devices and have saved MANY times the price of them saving batteries. Friend brought

With the center of gravity (centroid of mass?) being behind the landing gear, it seems to me taildraggers are an accident waiting to happen. They are inherently unstable. But if 100% of your landings are perfect and you know they will continue to be, regardless of weather then maybe you don't need

I dunno, but when the airliners get stored they do it in the desert. Think the driest they can find. I'm guessing, but maybe around 5% a lot of the year in the western deserts w/o the summer monsoon. Mojave Desert Rat, GeoB -Original Message- From: John Gotschall
