337.18mph is quick! Did Dave go to the Dominican Rep. to set the record as isn't there an AMA 200mph limit on jets in the USA for safety reasons?

Quote from article; "The record attempt had recently taken place on 18 January at the Hobbyland Airfield, also in Santo Domingo. There downwind and upwind speeds were taken to eliminate the influence of the wind amongst other factors."

So they only record the airspeed & not groundspeed?? Hmm, as the groundspeed while flying downwind would be the highest.

Still slow compared to the Dynamic Soaring WR of 399mph! http://www.rcspeeds.com/aircraftspeeds.aspx?rpt=LL

That pretty much makes poop out of the jet record, eh? I wonder what the Guinness folks would say if they knew about that.

it looks like this record was for 'jet powered aircraft' as opposed to slope soaring. pretty impressive for something under its own power.

Someone error-ed in the conversion.

They're say the jet was doing 393 knots (337mph)

NOPE!

If the jet was doing 393 knots, then the MPH converts to roughly 452mph

If the jet was doing 337.18 mph then that converts to roughly 293 knots.

Which is it Guinness!? Perhaps neither???

Perhaps it was 293 knots? Yeh, I think so.

Looks right to me. Maybe they changed it after noticing their error.
were able to fly their radio controlled jet to maximum speeds of 542.64 Km/h (293 Knots or 337.18 mph

Here's the Video

Yeah Dave Shulman is probably the best jet pilot in the country.. Shame about all the controversy with BVM and the JPO and all that.. That would be a shame if they tried to go after his waiver even though he did it in another country..

Shui used to be his employee and now it's looks like nothing but a bunch of sour (albeit purple colored!) grapes!

They have it wrong on the video. The text is correct.

Because jet guys have big egos and Bob Violet thinks he controls the whole sport.. His kits are very nice and expensive and fly well, and Shulman used to be his star pilot.. I don't know what happened internally at BVM for all the haterade, but they keep quoting the 200 mph limit which is totally enforcable at an AMA field.. inside the United States.. (Hence the reason for this record being outside the US) The same thing happened years ago when the guy that owned AMT USA built this Concorde that was massive and weighed nearly 200 lbs and had 4 50 lb turbines in it.. It was shown all over the US at trade shows.. Terry Nitsch who if a very well known jet pilot was supposed to test fly it in the Utah salt flats with nobody around for miles.. The AMA got wind of it and threatened to yank his turbine waiver so the jet never flew..

I find it more than a little amusing that a ≤$1000 pure glider has clobbered a ≥$10,000 turbine jet by nearly 20% for the RC aircraft world speed record.

(Here's a 392 mph glider run -- Spencer Lisenby holds the record at 399)

The deal is the glider can't duplicate it "on demand". The conditions have to be just perfect and the Guiness people have to be there to witness it.. Having your buddy on a slope with a radar gun post it on youtube doesn't count..

For the sake of factual comparison it counts just fine.
The deal is the glider can't duplicate it "on demand".
Yet the record stands despite all protests to the contrary -- for now at least.

DS'ing speed records are probably approaching their maximum due to the physical limits of aerodynamics, hydrodynamics and construction materials, whereas anyone can easily put a more powerful turbine in an RC jet.

Here's Spencer Lisenby's 399 mph world record model aircraft speed run, flown at the Weldon slope site east of Lake Isabella in SoCal.

I think it was Spencer Lisenby on one of his record runs that he said he felt he could easily go faster. He reckons 500mph!

Seems the limiting factor is wind speed, heck they could fly in 100mph winds. However wing strength sounds like a limiting factor too.

As for 500mph, try keeping up with that when flying!

I've read or heard that wing loading can exceed 30 G's during DS'ing. I can't imagine what a glider wing could be built from which could be thin enough to be 'slippery' enough, yet still strong enough to handle the 40+ G's that 500 mph would probably hammer it with. Wow.

Lets see the guy duplicate the jet record during the next hurricane.

You are fooling yourself if you believe the jet record setters were not waiting for perfect conditions as well...

Stupidity can be cured. Ignorance is for life!
