Here is a friend of mine showcasing his new indoor ducted fan package which will be installed in a Depron F9F-Panther jet......
Vid of the system in action can be found Here

Here are a couple of images of the Panther.........

That is nice. Scratch built or a kit? If it is a kit, can you post which one.

PS B25 coming on, but slowly. Bit the bullet and ditched the engines it came with and went brushless.............got a major pain in the wallet for my efforts  :'(

Looks good!

I made a model (just display) for science fair using styrofoam and found that I'm really good at it!  Is it possible to use styrofoam to make flying models?

[expat]

The best foam to make flying models is a product called "Elopor". It is very strong and flexible. Also if dented, with careful application of hot water you can pull the dents out.
Styrofoam can be used, but it requires sealing. If you scratch build I would go with Elopor, but that is one persons opinion only.

What is the size on the EDF unit?  Looks tiny.  ;D

[Rifleman]

The actual fan unit is about one inch in diameter........

The foam we use over here in Canada is called Depron.....Yanks also call it the same and I was sure that some of the Europeans do too........This was a scratch build with markings done by the builder also..... 8-)

This was a mid build image.........

In all of the pictures it looks like a professionally made kit. I take my hat off, you friend has done a great job. The markings are superbly applied.

PS I don't suppose that he made some plans in a handy computer email sized file did he...............hint, hint  :)

A little further info on the 16" wingspan Depron Panther.........

Motor is a 7mm pager with a 3.3 ohm resistance turning a 1 inch internal dia. fan for 7.8 gms of thrust....supplied by a 220 mah Atomic Li-po single cell with a 17C discharge rate.....controlled by a Plantraco receiver sending signals to two .4 gm actuators, one each moving elevator and rudder through push rods.......

RTF weight is 26 gms in this configuration.......

my guess would be Coleman?

[Rifleman]

Who else, Kalon ..........?

You know what he can do.........

[no_lak]

he is damn good with creating things from nothing!!!

[Rifleman]

Although he sent me a vid of it flying, he asked me not to upload it until he has one of it flying to his satisfaction.........

I thought it was fine for a test flight...... :-?
