Pete's Pietenpol Prototype (P. Rake's 1/6 scale Air Camper)

Pete made me another offer I couldn't refuse. A 1/6 scale (58" ws) Pietenpol Air Camper.

The Plane -
The Air Camper, a two-seat parasol wing monoplane is a famous homebuilt kit plane that has been around for over 80 years. It has a wingspan of 29' and a length of 17' 8". Bernard Pietenpol designed the Air Camper to be easily and cheaply built. The plans first appeared in the 1932 issue of Popular Mechanic's " Flying and Glider Manual". The Air Camper is made of mostly spruce and plywood and can be powered by a Ford Model A, a Ford V8, a Chevy Corvair, a Lycoming or other readily available engines. Bernard's son and grandson still sell the plans and Air Campers are still being built. They say for about $9111 (2008 dollars) and a lot of scrounging plus 1000 hours of free love construction time a pilot can be in the air. Tempting isn't it .

There is a veritable treasure trove of info on the 'net:

The Model -
The model's wingspan is 58". To fit in my car the wings will be removeable.
AUW is ? (What's the best way to guesstimate AUW?)
Since the Model A engine and radiator is so prominent I'm definitely going to have to give it the "full Maltone". Hmm maybe I can sub-contract the engine to Pat

The Kit -
Vicki and Charlie at Manzano have done their typical bang up job with the short kit. The USPS didn't do them any favors though. When the box arrived at my house, it was smashed flat but luckily the only damage was to some excess balsa pieces.

Great subject Tim - at 1/6 scale, you could add or subtract as much detail as you want or dare! Should be a great flyer - and all that reference material........... Looking forward to the build.

You mean you choose to paint the cowl rather than do all the turning on the bare metal!? Ha!

Maybe you could stash the ESC in the radiator for good cooling... This will be a good size! I'm watching.

This should be delightful. Just the model for pottering about the field on a calm day.

Yes she is!!!! Now if Peter would be willing to do the Pietenpol Sky Scout as well. It is virtually the same airplane style but only a single seater. I have a copy of the 1933 Flying Manual with the 3 views, plans and detail drawings. One could actually build the real thing using the book I have. I also have the earlier one for the Pietenpol Aircamper as well. It has a ton of information and detailed, dimensioned drawings for the fittings etc... It even has a chapter on how to convert the Model "A" Engine..


BTW the Sky Scout particulars are as follows.

LENGTH: 16'-3"
WINGSPAN: 27'-3"
CHORD: 5'

What do you say Pete!!!!

NEWTRON: I would be willing to share any of the detailed drawings or the entire article on the Aircamper if you so desire. Seriously, at 1/6 scale you could really do a job. Please let me know.

Greg,
Yes please mate. You know I never turn down any information that might lead to another drawing job. Two Piets have to be better than one - in two sizes.

Oh well, I can cross that one off my list of possibles

Had looked hard at a 1/6th 'Sky Scout' - have that '33 'Flying Manual' too - but reality precludes starting any new projects right now, so I'll just follow this thread!

Should be a dream to fly though, an ideal scale model for loafing around the patch on quiet days. Good luck with the project.

Subscribed. I have some pictures of at least one Piet I took at a "Fly-in" years ago. I believe it was maroon and cream. Always liked that one.

Jack,
Thanks for the offer. I'd like to give it a try first. If I embarass myself I'll give you a call.

I'll have to find the album they are in and scan them in. They are that old.

Required motor and parts

I'm still in the planning stage right now.
The Motor -
Pete drew an axi 2814 on the plan so that gives me somewhere to start. The axi 2814 seems to be roughly equivalent to a .25-.35 glow. Hobby Lobby sells it.
It appears that Hobby King's Turnigy TR35-36C and Grayson Hobby's GH2814-08 are equivalents.
All 3 motors are rated to turn at most a 10x5 prop. I haven't done the math yet but I would think a larger prop would "look" better.

The Shopping List -
I gave the plans a quick once-over and came up with a shopping list to get me started:
10 swg wire (landing gear)
4" wheels
6 mm CF tube and aluminum (removeable wings)
3/16" basswood (spars)
3/16" hardwood (inner and outer struts)
3/16" balsa (tailplane)
1/4" balsa (LE)
1/32" brass (strut connectors - I'll copy Maltone and use a soda can cut into strips)
1/4" ply (UC attachment points)

Pete - my previous Rake's all included the balsa/ply required to make the wheels and the ply UC pieces. Did they not make the cut or is this one different?
