Does anyone have any experience with the Fly Henry engine monitors from the Czech Republic? The little PPG Meter (tach/fuel level/CHT/EGT) looks good for little two-stroke-powered plane like a MiniMax and the larger Fly Meter (tach/fuel level/fuel flow/oil press/oil temp/4 CHT or EGT/volts) looks interesting for something with a VW or other small four-stroke. With a base price of about $200 and $300 respectively (plus senders) they seem pretty reasonable. See http://www.flyhenry.cz/ or http://flyhenry.us/ or other sites.
