Dave 'I swore I'd never crow-hop' Hyde Just don't try to imitate the Emmeraud here at 3BS. it had a 125 HP engine and was designed for about 65 or so. The pilot only had a few hours of tail dragger time...wayyyy back when he'd been checked out. For some strange reason he fire walled it and it went ballistic instead of accelerating down the runway. What goes straight up usually comes straight down. The lift from the wing brought the nose back up and it hit just the south of the runway. The only damage to the plane was it broke both main gear off the spar and put a crack in the right side cowl...and the two sets of teeth marks in the glare shield. It's been rebuilt and is now regularly flying.

I had intended to do a few medium speed runs, raising the tail each time, then pull the cowl and check things over. I'm not cruising around with the tail up, it's just power up, tail up, power back and stop. Second run I could feel it getting light on the gear. Third run I guess I didn't get as much forward stick as before, so the attitude was a little more nose-high, and it rotated on the mains and popped off the ground. Airspeed was out of my scan at that point, but it must've been around 45 knots or so, so I wasn't going to horse it into the air and take it around. I had plenty of runway, so I throttled back, held the attitude, and let it settle. I wasn't 100% sure I was airborne until the tires chirped on touchdown. Next comment (on tape), "I guess I know it flies now." Observations: Acceleration is faster than I expected - I've never flown an RV solo. I'd planned on good accel, but it was more than I expected. Tail comes up sooner than expected too. See above. Takes longer than I expected to slow to taxi speed...although time compression may have something to do with that g Everything felt great control-wise. No gross trim problems noted. By the way, I was doing this prepared for a flight if something like this happened. Flight-ready airplane, parachute, gas, preflight/runup, etc., so if it turned into a first flight I could minimize the surprises and not get caught in something too ugly. Dave 'taxi stand' Hyde |

Tail comes up sooner than expected too. See above. You have considerably more experience than I:-)) I have flown one twice, but it was a nose dragger (6A) and never solo. It was a nice flying plane. Light on the controls, but overly so and good harmony. *Nothing* like the GP4 I flew. Takes longer than I expected to slow to taxi speed...although time compression may have something to do with that g Wait till you're coming back in to land it the first time. I'll bet it's at least as exciting as your first solo landing as a student:-)) Everything felt great control-wise. No gross trim problems noted. Glad to hear that. Of all the planes we've had solo out here at 3BS only a couple needed some tuning of the rigging. By the way, I was doing this prepared for a flight if something like this happened. Flight-ready airplane, parachute, gas, preflight/runup, etc., so if it turned into a first flight I could minimize the surprises and not get caught in something too ugly. Parachute? Just cause it's a first flight of one "You put together"? You should have more faith in the builderLOL I'll be wearing one through the flight test phase for the G-III if I ever get it off the ground. I'll probably be too old to fly by then. Dave 'taxi stand' Hyde Keep up the good work!

Observations:
Acceleration is faster than I expected - I've never flown an RV solo. I'd planned on good accel, but it was more than I expected. Yeah, it'll press you back into the seat... what model and engine do you have? Tail comes up sooner than expected too. See above. It does... my dad yelled at me the first few times I took off (he's been giving me unofficial taildragger training, with the intent of getting me to the point of just being able to have a CFI sign me off) since by the time I would raise the tail we'd already be at flying speed... Takes longer than I expected to slow to taxi speed...although time compression may have something to do with that g Nope, not time compression there... and if you leave even the tiniest smidge of power on by accident, it takes an eternity. These planes do not like to slow down... |

Takes longer than I expected to slow to taxi speed... Dave 'taxi stand' Hyde +++++++++++++++++++++++++++++ {Everything is even a tad quicker in the RV-3.] As to slowing down to taxi speeds -- My RV-3 never does... WITHOUT brake application on a paved strip of 4500 feet even when 3 pointing on the first 600 feet, The 69 inch pitch prop and 650 rpm idle, keeps the RV-3 trucking almost indefinitely over 30 mph without minor brake application on hard surface. If your idle and prop pitch are above that... so much the worse. P.S. Grass, of course, is a different story. Barnyard BOb - do the math |
