F35 70mm EDF Profile

I have been building a profile based F35 70mm EDF out of 1/2" Dow blue foam, 1" R tech 25psi white foam and 1 piece of dollar tree. I have the log in power point. The plane is almost done and I am going to try to post the power point on here for your comments. I have not tried to do this with power point so I will see what happens. If it doesnt work I will have to just post the pictures and text normally. This will be the first build log I post so please bear with me.

The presentation was excellent! I'm no guru on these, but on page 38, rear view of body tube, I would call it a thrust tube, but it has no taper!! You will have no velocity to speak of. Go here and download the FSA calculator, to. figure out what you FSA is. I'm nor sure what its supposed to be, 85%, at a guess, but check tht out. Other wise. it looks good.http://www.rcgroups.com/forums/showp...11&postcount=4 good luck.

Thank you for the input. I dont have the measurments with me but I tried to make the opening at 90% of FSA, but I did the calculations by hand. Thank you for the info on the calculator, that will definately be more accurate for my next build.
