How about Sunday September 4, 2011. 1:00pm to 4:00pm or when we run out of jets. Lunch at 12:00 noon. We will do a BBQ in the Corporate Tent. We may have to charge a small fee depending on the ruling from the Chancellor of the Exchequer or failing that the President will issue a proclamation. All this debt stuff in the States is getting to me.
How about it. If you'd come let me know so I know how much food to bring.
Jack.
I'll be in Chicago.
Count me out.
Would love to have an EDF fun fly, got some new planes to show! Unfortunately, can't make 14th Aug........ :'(
I would like to Join, but NO EDF's at this time...
What about Labour Day weekend?
OK. Sunday September 5 it is.
Jack
If the tax payers allow me to take a day off I will fly EDF jets on that day.
Damn, that's the Hinchcliffe Family Annual Summer vacation week! (Similar to National Lampoons Vacation..... :P)
And I changed it for you and Michael.
Change your holiday plans and get your priorities sorted.
Jack.
I plan to get into EDFs in the next couple weeks, so count me in.
To up the ante a bit, perhaps we could source a radar gun for the club and do some unofficial speed testing of the various models/fans.
Ken Coleman did get a gun but could not read even a 1/4 scale cub at 30'. We would need a very expensive model with high resolution.
Jack.
you can calculate speeds with a video camera using the dopler method..
Hi Ed, how would you do that?
Jack.

A quick Google search and I found this:

Seemed to work well for $69 bucks, the reviewer gave it 5-stars.
Flying directly over someone holding a radar gun seems a little out of the safety code. Any volunteers? My gp rifle should be ready in a week and should do 135mph+ (215kph)
I don't think the angle at which readings are taken matters.
This unit seems to be very popular with the RC car and boat crowd.
Not trying to be a pain. But I did a little search and found this.
(Q)How important is it to stand in front or behind the object when measuring its speed?
(A)Somewhat important. The less the radar is directly in front of or directly behind the target object, the lower the measured speed (the Cosine Effect). The error is directly proportional to the angle off the direction of the target object. An angle error of about 25 degrees equates to about a 10 percent error (reading low by 10%).
Just to be clear when Ken attempted to take readings it was from behind the fence. I suspect the problem is insufficient reflective mass to generate a return signal. If Ken puts aluminum foil on one side of his Formosa he might get a reading???
