Great work and very good looking model ! Congrats!

Can you provide pictures of the cowling and how you mounted the motor ?

Thanks!

Rascal using Blue Cor (Dow Corning). If you look this model had a slight undercamber and it allowed for faster and very good responsive flight!

I still have this model and all I need to to fix the frontal fuse.

Dave,

Great subject and beautiful workmanship. The one with actual windows on white DEPRON should be awesome.

Depron as well as FFF are great mediums when the goal is a nice looking yet very fast built model.

Here's a link to a Citabria I built with FFF:

The whole plane was complete in two days. It's 32" wingspan, about 7.5 to 8 ounces. It flew great with the IPS setup, very similar to yours.

I'll be looking forward to more of your models!!.

Happy Landings!!.

Gerry.

Depron Dave · Jan 28, 2005, 02:37 PM

It has a 40" wingspan
3 channels, you could throw ailerons on it but I wanted to keep it light
2 HS-50's and a GWS RX for control
A IPS-DX-A I pulled out of an old beat up GWS tigermoth kit
9 or 10 inch prop
2 cell 350 lipo is what the prototype is flying with on the video
I'm going to try it on a stock $4 cd motor, see how it handles
they worked great on the Bronco. Just the cost of the speed control
will bite the wallet a little.
we kept folding the unreinforced wings, this has a carbon spar so the weight will go up. I could use tape, but I fly hard when egged on by freinds.

The small holes on the cowl will have two balsa crossmembers to support
the motor stick.
The plane is all 3mm depron I'll weigh it tonight.

Dave,

Light colored tape is what Gerry (a.k.a., SIMANO) used on his foam creations and he has never had a folding wing yet. The Tape is also a very good scale effect and makes the model look like it was covered with mylar covering of some sort. The tape is rather translucent depending on the color you chose but, the dark ones such as Navy Blue are great and it provides very good strength to any stress point instead of carbon rods etc...

Take a look at his threads.

That looks like a scaled down version of one that appeared in FLY RC...I started one in depron, but got wrapped up in a micro-heli and (hirobo) and have not finished it.

Cruzer · Jan 28, 2005, 09:09 PM

Looks great Depron Dave,

You should do a thread how you build with Depron. I know I would read it. Would be great to see how you are building and forming with the Depron.

Rob,

Depron Dave · Jan 28, 2005, 11:56 PM

I do alot of work in Graphite (ashlar product)
there is some trial and error when bending the pieces around the bulkheads
I also groove the depron with a dremel and little router attachment

Here is what the cowl layout looks like

Depron Dave · Jan 28, 2005, 11:59 PM

this is the router attachment
this makes short work of grooving things
I use a small straight edge when I do this
Here is a pic from the Bronco manual

Depron Dave · Feb 01, 2005, 01:47 AM

WINDOWS WINDOWS WIDOWS
Yup, ready for paint..and a pilot figure?
My lovley wife has cut my painting stencils.

Hi Dave, sent you a pm. Would hope to be able to get the plans from you.

Depron Dave · Feb 07, 2005, 01:20 AM

Painted and flew the final version of the Birddog this weekend
weather was bad till 4:30 so the flight pics are a little dark
It's a very visible paint scheme.
