have you looked at the wings from a skylite?I just picked one up.the wings are light,the plane is only 178lbs with out the motor..I ordered some cromemolly tubing to make the motor mount.trying to stay under 254lbs.the fuselage is all cromemolly tubing 1/2in.I traded off a 2 seater condor ul for this plane so I could stay 103.right now there is no schools to get a sp lic here.I will look in to it at a later time when thay get all the bugs out of sp.for now I just want to fly low and slow

We think alike Dan.
I have liked this design from the beginning because of it's
simplicity but the bottom line is that it is way to HEAVY for 103. A
few years back I built the basic fuselage but stopped halve way into
when I saw how over weight this structure was going to end up
being. I currently fly a Flightstar that is also way to heavy for
103. I have no desire to go SP myself; takes the fun out flying IMO.
- Use the same wing as the Legal Eagle. Made of wood, very light and
very strong. I built a set of these wings before (same wing from
MiniMax) and they are LIGHT.
- Get ride of the wheelbarrow tiers and go with the some lightweight
bicycle tiers, also like the Legal Eagle.
- I agree on your idea of using .058 tubing for the aft section.
- Need to come up with a lighter way to attach the 2"x2" square
tubing; the .125 6061 plate is just too heavy and there is a lot of
- Skip the cowling.
- Lighting holes in the 2"x2" square tubing? I am not a mechanical
engineer so I am not sure how far you could go before compromising
the strength too much.
