I may not be able to get them off Ryan until tonight (10am here), but I'll get them to you first opportunity and I'll mark them on the plans.

cool , keep me posted

During last two years, my own thinking about the belly landing got a 180deg twist after seeing Multiplex Easystar.
Earlier I was also insisting for the landing gear but according to me belly landing is the most safe and convenient landing.

The belly of the plane has to be made slightly flat similar to Easystar and should have extra protective covering.

Tips of the wings should be similar to that of Easystar as such type of wings provide wonderful stability to the plane and are ideal for belly landing planes.

Thanks for the feedback. I'm sure we'll be able to adapt this for either wheeled landing or belly landing.
You raise very good points.

Clark-Y set to 12% thickness

Belly landing is just fine with this design. May round off the wing tip or sweep the tips up abit

No need for wash out, don't think it will be worth it for something this small
Projected max weight is ~3.0kg.
10" prop is fine. Only need .4 : 1 thrust to weight ratio, people flies way over powered!
If you want bigger prop, use 3 blades

I think that for something this small most aerodynamic refinements won't do much justice.

Just a few small changed to an excellent base. I changed the Wing, the Airfoil is a NACA2414 at about 12%, Wingspan 1670 with the Tips added. Changes to the motor area with cooling etc.
It was re-drawn in SW2010 as I plan to add more contruction inside so I can laser cut the parts and maybe make a mould after test flights.
More than welcome the the Files, not sure SW2009 will read the 2010...?

@Ryan - did your version read the parasolids I sent?

Comment by Dave Buckley on November 19, 2010 at 8:33pm

Are we abandoning landing gear in favour of a belly lander?
...
Bueller?

Well, how's the CFD going?
Couldn't anyone just do a simple flow with Cosmos at different Alpha?

Gear or no gear - that's the builder's choice.
