My 503 runs at 1200 in the range you state above, but cools down a little at
full throttle. CHT is a little less than 300.
That was a quote by Mr. Murr on the list. That's exactly what I get with my
503 that I've taken (and still take) well over 1,200 hours with only 3 tops. I
use Amoco Super Premium & Pennzoil 2-sicle for air breathers. I would
honestly say that 50% of those hours are wide open, full throttle towing hang
gliders. I do change plugs at 25 hours.
I also took a 582 mounted on my Maxair on Full Lotus floats to over 1,200
hours. Most of that time was at high power settings hauling the floats &
sometimes a passenger. My biggest mistake was listening to other people telling me
I should overhaul it. I did. Over the next 2 months I had 4 engine failures
landing in everything from sugar cane fields to cow pastures.
There's a story behing that however...When we overhauled it, we changed the
motor from it's standard upside-down position (Maxair standard mount) to a
rightside-up position to swing a bigger prop. We neglected to change the
position of the little crankcase oil supply tank.
Just food for thought...
