Subject: | Grove Gear Climb and Speed Data Part 2 |
--> RV8-List message posted by: Rob Miller <rmill2000@yahoo.com>
Hi guys
For those of you following this thread. 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.
