Canards on a 200" FED

I've got dual element canards on my 200" FED NE1 car. Are they working at all? I've been tempted to pull them off.

At what speed would i expect to see gains down track?

I currently run about 182-183mph. It feels very solid down track. This is our retired a/f car. It used to run 224mph +/-

 

hey Greg...... i'm not gonna tell ya if they work or not.... but i do know that being close to the front of the tire is hindering them....Mike

 

Hindering, like they are in dirty air and not helping that much?

 

Bill Wayne says you get about 5 mph with out them! I've run with and with out,cant tell the difference at all.. But Bill has tested different things.You might wanna talk to him

 

Thanks, i think Bill will be here next weekend for the A/F HRHS race. I will do that.

And, they aren't as close as the first picture makes them out to be. here is another shot.

Greg, DO NOT take them off!

Dad has some software from NASA (If I recall correctly) that will amaze you with how much downforce these canards produce.

If you cannot find it on the HRE site let me know. I have it on my laptop and can send it to ya...

all that downforce= loss of speed!!!! talk to Bill He is as smart as anyone out there. We dont need all that downforce to hold us down.I take mine off on good tracks,and leave em on on the slick tracks

 

I disagree.

Downforce doesn't reduce your speed. Drag does.

Efficient triple element or even dual element wings are a good thing!

PS Greg, did you find the software at Dad's? Search for canard and EDB.

 

Talk to Kin Bates and his guys,Jim Archer can tell you all about this stuff!!!
They are all real good people,and will tell you anything you wanna know.

 

well, what did we learn??? Mike

 

The guys will be in Sac next weekend. I have noticed i'm about the only NE1 car with canards. Most 7.0Pro cars don't seem to have them

 

Greg, do your wings have wickerbills?

EDB

 

because you dont need em!!!!
