Thanks for your answer Don;

I did a spreadsheet(.XLSX) of the Snorri Gudmundsson book 'GA aircraft design' on chapter 18 'Performance Climb'. It is quite self
explainatory, but I didn't used column Advance Ratio for the...
The Rose Parakeet biplane website has gone. It was a valuable source of information on this fine biplane.
In these few weeks reviewing my goals, I finally found it more appealing with a single strut on each wing
forgot foldable wings and aluminium round spar, so no worry about jury struts.

Thanks for your answer. How to deal with aluminium spar deflexion and plain flaps
and aileron elasticity ? With aluminium and same modulus of elasticity, it seems
there are no other option. Wood...
I can't figure out completely how jury struts work.
I clearly understand that jury struts can help and suppress buckling
of struts in compression (with spar in tension in negative load).
I've...

BTW this car looks "really" like a GAZ :-)
I didn't know even maker or country of origin. Thanks for info!

Albeit a counterintuitive task, playing with polars (airspeed/rate of descent and lift/drag coefficient)
gives you a glimpse of a glider performance.

A good description of shock cords is there

I'm concerned with strength of undercarriage and dimension of bungee cord shock absorbers.I didn't ...
Thanks for answering, PTC did the Pro Engineer CAD suite (and recently Onshape Online CAD system) so I bet MathCad is a good product, and certainly old version too.
Have you a prefered computer algebra system (free or not) ? There's a bunch of it nowadays

Ask help from a local EAA counselor for needs of restoring it (fabric, engine, instruments). Nevada, IA is central, and I don't know if it's wet or not. I don't know if an emeraude is rare on the...
20000$ on barnstormers (search "emeraude") on that day. This fine airplane has the most pleasant control harmony and is a joy to fly.
Put your 5000$ in for flying it safely (extensive carry-through...
Cross section of fuselage is enlarged by spar and position of pilot, passenger, side by side
semi-reclined seated.
What is your opinion about this configuration as cross section of fuselage is...
Fitting Graham Lee datasheet with rotax 503 numbers gives you a CD0=0.07 (parasitic and interference
drag of whole aircraft). It gives a L/D ratio of 7 (with induced drag K=0.0725), so I trust you...

I did a spreadsheet for the Graham Lee Electric Nieuport 11, it may work for a
Lithium Nickel Manganese Cobalt Oxide Battery at 0.22KWh/kg (that is quite
optimistic).

As seen in South Africa "kitplanes for africa".
With a tight fit, I don't see why it wouldn't work (and examples are flying).

Here are some notes and calculus.

I'm interested in as strength as possible so 0.083" with wood doubler is my choice.
Thanks for sharing but this tube is for wing spars, 0.083" wall is for strength, (0.035" and 0.065" wall is too thin, 0.125" is
too heavy).2"-1/2 OD is for leading edge radius.
