Sky9pilot....I should of....I got lost in 'wrapping' the power pod and still keeping it scale-ish. If we build another one, the motor needs to be 1 section closer to the nose, and place the battery pack/timer one the cg. I would also try to make a cheater door on the bottom side Tongue
As it is, I've learned a lot, I may cut the canopy open in the front, a 'scoop'....because my intake is the same size as my exhaust...
Anyways I'll show the batt door, and how it's held on. I soldered 2 short brass to pins, the the aluminum tubes go through them, back to a wall. To change the 70mah battery you will just pull these out, and the door falls off.


Pins are yet to be anchored.....

Might I suggest 1/16"X1/32" stringers attached on the 1/32" edge. Koutny style that yields a nice round fuselage without the weight of using 1/16"sq stringers.

I didn't think of that...but the motor is only like 4mm....set in thin music wire....I finalized the last part of the duct tube. Seems a slight reduction yielded a better airflow that the straight tube!


Got a micro leaf blower Grin
Now, the trick will be to get a round body shape without adding tons of weight....

Looking good.  Have you considered a cone on the back side of the motor to smooth out the airflow?
I'm looking forward to see this come together!

Yes!....I'm sure my little motor won't put out that much power for a hover!


Progress, and you can see the constricted tail pipe....I'm gonna try to test it today. If it's to much reduction....I will have to cheat some with a larger exit, and throw scale out the window.
Once I think the power package will push enough to keep her flying, ill button up the fuse and cover her.....test again to see if enough inlet air is ok.....then lightweight wings and tail feathers.
Cool

So you're going for more of a Caproni ducted fan setup.  Here's an interesting video of an rc Caproni Click Here

THAT'S a feat to have a rubber ducted fan!...it climbed out and made circles! Shocked
Mine is shaping up some, you can see how I think the power package will work....


Slow going, I need to weigh these...but whatever the weight I will go forward as I'm building as light as I know how...

Here we go.....had this kit as a gift, motor and battery too! Smiley
My friends give me stuff and see what I come up with....THIS build will be a buried hot drone motor, with its prop, as you see, she's got a micro timer, and tiny 25mah battery.
The idea I have is a stiff but lite center section, where power package will be, and the wings attach there also.
Kit calls for solid tail feathers.....I believe a lighter skeleton group will be built....and attached after some tube experiments are completed.
What's got to be figured out is, will a slight choke on exit air ok? Or will a need to keep power section same diameter all the way out?
I need to keep power to weight close to make this a bird instead of hanger queen....
