I have been progressively adding Grove gear to my O-360/Hartzell powered RV-8. I was interested in how each additional component added (or subtracted) from speed and climb performance. Speed numbers were obtained by GPS with full throttle (about 19.4" MAP), EGT 1300, at 11,500 MSL--(This is about 65% power). Weight OAT Climb Rate to 11K Speed MPH Van's Standard Gear 1525 55F 1025 184 plain-no fairings/pants Grove Streamlined Gear 1514 43F 1242 185 plain--no fairings/pants Grove w/intersection 1515 50F 1252 187 fairings, access covers, but NO wheel pants. Grove w/all fairings and Data Coming Next Week wheel pants **Note: Stall speed (clean) was reduced by 7 knots with the addition of intersection fairings. See www.RV-8.com for the theory behind this -8 phenomenon. Rob Miller -8 N262RM "Bad Cat" 50 hours http://platinum.yahoo.com
