specs for wing on FED
GlennLever:
I don't know, but I don't think you ever want to take weight of the front and with the wing in back of the rear wheels it does not seem the right thing to do?

I figure the front canards will off set the wing.Plus remember wing angle effect amount of down force.A well designe wing can be run at negative angle and still provide down force.I think the key is how much down force you have. With my motor being 51" out I think it will be benifical.If not It only cost me the price of the airfoil tubing and thats enough. I have templet I got from wing off my TA/D and it came from fellow I met in Gainsville who worked for this little company NASA you may have heard of it.
I spent cpl hours talking with him and got ton of info.Plus he was buuilding wings for guys like Jay Payne at the time.I'm going to reduce the size some since this car is nowhere near 3000 hp,lucky if getting much pass 1000 before nitrous.
The more I play with this setup thye more I like it.Kind of ties the nostalgia to the new. If not using name Starr Rider I will use the Newstalgia which was idea from start of wanting a modernized FED when I drew first sketchs. Man that issue of Drag Racer that had blue and yellow Jr fueler I think little huslter has cost me lot more then cover price.
Hey Glen Im sure few thought the first guy to put a blower on dagster engine was crazy too.

YUP them NASA guys got's those Aliens that they been keepn alive for years, (area 51) making them tell all kinds of space secrets. Your car is gunna fly. ;D

looks like 4 aliens escaped and are living in washington at 1600 pennsylvania ave. Suppose to fly thats why it has parachute.

with battery 35 lbs. fuel tanke 4.5 gallon 36 lbs full fire bottle 5 lbs and nitrous bottle 18-23 lbs and all mounted as far foward as possible.Then Im sitting more foward with the high chair postion and rear end is almost tucked under my rear and the motor being 51" out I think there is lot more than normal weight on front. I will be weighing it before hitting the track to check how much front and rear weight.
Starting with 480 sq in of wing and at -2 degrees and move up till I get to +4* or I feel it needs to be moved back. Sheets for this wing design show 163 lbs down force at 200 mph.Plus 90% of runs will be 1/8 and only 150 to 160 mph which is around 104 lbs down force.Plus front canards have to provide some down force.
Worst case I pull wing and mount the canrds in front of rear wheels or better yet the aerodynamic effects I have designed that also add down force.
