    Lazair on Floats with Rotax 185's needs more power, Ideas?

    That $750 doesn't include the Header Exhaust. 225cc Tillotson Performance Engine Power Graph below. Probably not the best CAM for Airplane use. The Power Band is too High. You want the Power Band at 3000-5500rpm to look like this one does at 4600-6600rpm Smooth, no Blips. The Rotax 185UL just...
