Out of curiosity, what is the VMO for the 501, and have you ever exceded it?
TIA.

I V maxed a Piper Tomahawk once. Tore the tail completely off and I fluttered down to Earth like a falling leaf.

Actually, I did throw the 4-stroke Engine off a 1/4 scale bi-plane once.

There's a member here named 'winnard' who was a witness.

I'm holding short, waiting to takeoff and grabbed the camera.

For the C501, Vmo is 266 kts indicated below FL140 and 277 kts ind. above FL140. Mmo is .705

And as I speak into the microphone. No sir I have never exceeded it.

Theres an argument on another forum about how much an a/c can exceed VMO. Moreover, the 762 into the trade center. Their talking about why it's wings didn't fold at 466 kias.

The wings didn't fold because they didn't exceed their G-limit. For most U.S. certified aircraft V-dive or ‘Vd’ is 1.2 times Max Operating. So an aircraft can exceed Vmo by a factor of 1.2 and remain structurally intact. However, there’s usually a factor of safety built into the aircraft design allowing for even a further exceedance. You must also realize that exceeding an airspeed limitation doesn’t necessarily mean the wings or tail will fold.

Do you have a link?

I had a 1.20 Size 4 stroke with a 16" prop buzzing at 9,000 RPM. It was mounted on a model airplane made mostly of balsa;)

I had been flying for awhile with nylon mounts to the firewall, but this day it gave way when I did a really hard snap roll. It threw the engine and the airplane fluttered down, like a leaf.

When I re-mounted the engine, I used aluminum mounts

I eventually lost this airplane in Lake Hefner.

Nylon mounts are for wing bolts and landing gear bolts ONLY. ;)

Here's an airplane that I still have. I haven't flown it in 3 years, though. To give you an idea of how big it is, the prop is 18" and the Saito 1.8 will turn it 10,000rpm

Beautiful a/c. I built my 1st about 7 years ago. 48" wingspan trainer. I swear I lost about 12lbs the first time I flew it.:D

I watched a buddy prang about as pretty a 1:20 scale Hawker Hurricane as you could ever hope to see. He lost R/C connectivity while inverted as I recall. It was totalled of course.

That's the major reason I switched hobbies from RC airplanes to guns. I don't have the money to be serious about both. You spend a $1000 on a rifle and will it to your grand-kids. You spend $1000 on a model and it can go *poof* at any time.

OK, there's some wacky folks and some smart ones on that post. That said, it's not much of a stretch to say an aircraft could and will fly above it's maximum dive speed. What that speed is exactly? No one really knows because test pilots usually don't make it a practice to dive the aircraft until the wings fold. It's based upon the structurally limit of the aircraft, flutter analysis and vibration characteristics of every little piece of something hanging onto the aircraft (structure or not). An analytical design speed is created and flight test are done to show the aircraft is controllable to that speed. Vmo/Mmo is artificially set at 80% the speed of the design dive speed to allow the commercial pilot a factor of safety.

That's what I was looking for. Thanks.
