My wing is complete now I am back to working on the fuselage. Having left the fuselage for a while I have come up with some different Ideas for it. My Eflite 6s 22.2v 5000ah 30c lipo battery is about a pound more than I figured on. So I took the air frame back to the shop and lightened it up even more I cut out the material between every other hole along The sides into diamond shapes and spent 1/2 a day drilling more holes in it .It is as light as it is going to get.  Unless I put a heilum bladder inside the fuslage and fill the Tundra tires with heilum as well ? I got a dual AR 7010 reciever when I got a 2.4 mhz module for my Futaba 9c I am going to separate the two recievers about 42 inches apart one at the front of the plane and one  above the plane at the rear in a plastic dome I am going to mount hte  Lypo batteryand the Castle Creations P
hoenix ice 100 ESC
one above and below a shelf at the front of the plane. Cooling air will come straight through the front and into the 80 mm Delta 32 EDF.I work from sketches heres is the latest sketch . You guys have a Great Day!

I am happy to see an update Carl. Keep going!

What about getting an idea of what kind of thrust you will have with the system? Before covering, rig up a 'pull stand' with some type of scale/balance system that will let you run the EDF up. You will then know true thrust value, the weight of the airframe (sans wing), and a generally good idea of the airspeed needed for flight.

She might fly but require a gorilla to toss her to airspeed. In that case, a drop off launch dolly might be the trick. ROG, drop the dolly, have some fun.

Cool but why EDF? Have you done the math because I am guessing 5-6 min of underpowered flight time tops.

Looks cool! Sketches are nice also.

R.D. The Specs that came with the motor say 5.2 lbs of thrust in the habu jet it is designed for they get 4.6 pounds of thrust  The habu has a take off weight of 7.2 pounds and a wing area of 392 SQ inches I have a wing area of 702 sq inches and aiming for a tale off weight of just over 5 pounds . Presently with the wind blowing up the cliff I  live at I climb to altitude with my radian pro and fly 20 minutes or more at a time mostly with the motor shut off I should be able to do the same with this .The other day the wind was blowing up the cliff I took the wing out to try and it was all I could do to hold on to it . once I assemble the air frame and components i am going to

make a test pull stand and see what kind of pull I Get. 

Brent. The EDF The Lypo  and  the  100A ESC all Fit in a F4 Phantom ARF I have been itching to buy and if it doesn't fly I have a 29cc gas motor out of a "Somthin Extra I got 25 years ago.You guys have a great day!
