They are cheap and supposed to be accurate. I was able to cross check with my panel ASI to verify readings. After verifying the panel ASI and plumbing I removed the Hall unit. I have a full enclosure and therefor use a static port mounted on the flat bottom of the nose cone.

Wonderful news to hear of another Mk III X in the air. You probably need to make some adjustments to the static port. You're probably pulling a little vacuum at the port. Could you have the float level set a little high in one carb so that it spills a little gas out the overflow? Did you put in a fuel return line to control the pressure going to the carbs?

Also what would I have to change or add? I know I have to add a radiator. I'm told I can use the same carbs and exhaust (with a different y-pipe), same ignition and possibly the same gearbox and prop. Engine mount? I'm sure I'm missing things here. I'm trying to decide before I send out the 503 to be overhauled. I can get an overhauled 582 Blue Head for $3575 or a Grey Head for $2775 and he'd give me $1000 for trading in my 503.

The blue head mods were primarily aimed at the powered parachute crowd to keep the engine from flash cooling on long descents. Get the 2 stroke Installation Manual and you can compare the dimensions of the 503 mounting stud spacing and the 582. If you can find a good "C" gearbox, you'll be happier with it than using a "B". If you use the "E" you need to move the engine back 3/4" from the stock Kolb 582 mount plate to get starter clearance to the back motor mount channel on the fuselage weldment. Contact me if you go with the 582 and I'll send you the article I wrote on adapting the Honda Sabre radiator. Tested to 116 degrees on a straight 5000 foot climb and temps never out of the green. Costs less than 1/5 what the Rotax dual radiator system costs.
