Mike S said:And if you look at the second photo on the VAF main site, he appears to be landing with a stopped prop, and the wheels are down.
That wheel sticking out sure doesnt look like it will slice through the water very well.

This is not an -A, it would be the solution for ground-loops.RV_7A said:Theres the long sought after solution to the "A" nose wheel collapse issue!!!!!

N941WR said:Makes me wonder how a 160 HP -9 would work. Better yet, a 135 hp O-290 powered -9.
N941WR said:Great job!
Why use a -7 and not the -9? I would think that the 9's longer, high lift wing, would be the better choice. More so since you can't do acro...

alpinelakespilot2000 said:Anybody have any details on what was done to beef up the structure? I noticed at Arlington that the empty weight was something like ~1527# and the gross was listed at ~2300-2400#.
Is there any additional structure to justify the huge increase in gross weight? If so, any details?
The *Aerocet 2200 are straight floats only (no gear) and they cost $17,000 (w/ no hardware). Not too bad. They displace 2230 lbs. fresh water. Straight floats make sense (cost & weight) especially if you live on a lake.questair said:The 2200 aeroset floats would be a perfect match as would the EDO 2000's and would not add too much weight after removal of the landing gear.
It took a while to find these Aerosets as Google didn't bring many good answers. Luckily someone else had also misspelled it as the brand is actually Aerocet. http://www.aerocet.comgmcjetpilot said:The Aerosest 2200 are straight floats only (no gear)...

The empty weight goes up and the gross weight goes up...so the useful load remains about the same. The justification for this is that the floats provide considerable lift while the airplane is flying.
Please somebody with experience correct me if I'm wrong here.
Maybe this is something for mythbusters but for now, THINK ABOUT IT... Floats are flat on the top and generally curved on the bottom. If there is lift, it would be negative lift. Also, I'm pretty sure that floats are generally installed with a slight negative angle of attack, not sure how much. This would mean huge negative lift and drag during cruise and less so in climb when at high angles of attack (for the wing).

RV7A on wheels (for now)
I think that the step on the bottom of the float would spoil any negative lift.
You may be right on the rest of it. I would sure like to get more information from the builder.

My RV-9, N942P put on Baumann 2100 straight floats two days ago. Test flights are positive and just minor adjustments needed. With 180 HP acceleration is very good, plane gets on the step right now and lift off comes quickly. Cyl temps around 400 on hottest cyl at warm OATs. Seeing 150MPH at 2300X 23"all with a 72" blended airfoil. Have ordered a 210 MT two blade CS ( 83") which will take a few pounds off the nose and which should provide considerably better performance.
Pictures? Very cool. Love to hear more about this.
