I did a quick built of a testbed pistachio all sheet Fokker D7 recently and thought of posting it here.

Based on a reduced Comet plan of the model, reduced to 8" wspan. AUW without rubber is 4.6g with the 4" Peck Propeller. I like the red & white variant, so decided to do just that.

It took me only about 4 nites to complete it. Will maiden it indoor coming weeks. hopefully she flies well.

Nice (and very quick work!) - I like the colouring of the sheet balsa. Is it acrylic? Smiley

Good luck with the test flying.

(Incidentally a testbed for what we wondered?)

DaddyO,

Yup, its hobby art acrylics (water soluble).

Its a testbed for an all sheet pistachio since there is none out there except for Blankenship's SE5a & Bristol Scout, hehe!

I did a bit of outdoor flying on the pistachio Fokker D7 after work last nite since the indoor hall is unavailable last weekend. Could'nt wait.

The Fokker needed some slight weight upfront to balance the model even with the heavy plastic prop upfront. I guess due to the relatively short nose.

Here's the link on you tube:-

900 winds on 0.065" 8 inch loop produced consistent stable flight of about 20+ seconds. It has good potential for 30+ seconds with more winds (maybe about 1000 winds or more) just like the pistachio SE5a. Further, there were some slight turbulence & moisture in the outdoor air last nite. Hopefully indoor flying would be better, we'll just have to see this coming weekend.

Looks terrific!

 I have a thing for all sheet scale caricatures. I recently re-obtained a plan of Walt Mooney's all sheet Tailwind ,from 1962. I had to blow it up by 110% to make 8". Bill Hannan offered several all sheet designs. Some quite elegant.

Hi,

That is one beautiful D7. I built the guillows when I was a kid back in the 70s. I didn't know about setting the CG and it crashed and burned then broke. It was tail heavy, and while the instructions told how to balance it, me in my infinite wisdom, wanted to keep it as light as possible, so I refused to put clay in the nose to balance it and suffered the result.

I hope yours flies well.

Thanks Donald. Yup! Rubber freeflight models need to be balanced well or else the inevitable will happen.

My pistachio Fokker D7 flew alright, about 30+ seconds on 0.065" rubber. Still intact in a small hangar box, and have not flown it for sometime now.

Very Cool! 30 seconds for a tiny plane like that is amazing to me.

That`s a gorgeous little thing.....I`m tempted to have a try at something similar.

The finish looks really good - did you tissue over the balsa?

Thanks! Glad you liked it.

It mostly sheet balsa except for the top fuselage which is tissue cover over balsa strips.
