Paul,
Sounds like you're waaaaaay fast in the pattern. My Velocity is heavier than your plane, and for a long runway, I shoot for 80-90 kts off the 180, 80 at the top of the glide slope, 75-80 over the fence depending on crosswind and 70-75 at the numbers depending on crosswind. I use my belly board all the time for landing and carry about 1500 rpm, the theory (key word here) being that if I have a power failure, I can retract the belly board and continue the march.
Have you done any slow flight yet? What is your canard stall speed? What kind of roll authority and pitch authority do you have at Vs + 5 kts? Vs + 10 kts? I believe you'd be a LOT more comfortable around touching down where you want to (like on the numbers), stopping the airplane, etc. if you were slower in the groove. Also, it's a lot easier to decelerate to touchdown speed over the numbers if you only have 5 kts or so to bleed off.
I try to minimize how much I have to decelerate in the pattern (past the 180) ... Jim S.

Hi, Tom....Unfortunately, I am still in flight testing phase, and I am slowly expanding the speed envelope 5 knots at a time to make sure there is no flutter, so this time I throttled back when the indicated airspeed hit 145 knots. Next flight, I will let it accelerate to 150 knots before throttling back, then the next aim is for 155 knots, etc until there just ain't no more. Then, I will push the nose over to gain more airspeed (5 knots at a time) until I reach at least 25% above normal cruise speed (whatever that may be). I need to know that the airframe/control surfaces are flutter-free. Part of the 40 hour test flight requirements. Unfortunately, I will probably get all that done, and by then I will probably have my super-duper street ported 4-port with NA rotors and housings assembled/installed, and will have to start testing at higher airspeeds than the stock turbo engine I now have (which does not have a turbo on it). My guestimate is that it would probably do around 160 knots in it's present configuration, but I don't know for sure. I DO know that it is difficult to slow down in the pattern. I try to maintain 120 knots downwind, 110 on base, 100 on short final and then 85 knots over the numbers, and if you are just 10 knots fast, you might as well just go around, because you will float most of the way down the runway trying to bleed off airspeed. I could probably trim a few knots off those speeds if there was no crosswind, but the airport I fly out of almost always has a crosswind. I have to throttle to just above an idle on entering downwind to try to slow her to 120 knots. I will be adding the low-drag wheelpants sometime in the future....that should yield an additional increase in airspeed. Take care. Paul Conner

Pardon me Paul for being so shallow, but how fast did you get it going?
