3grand! man that's a lot of time wasted on the computer! 8^) (I guess whether it's wasted or not depends on how much one learns from the experience!)

Your wing looks about right. Mine came out at exactly 6" aft of the fire wall. But, as the fuse is so narrow, and there's limited space to move the battery to achieve the correct CG location, I actually moved the wing about an eighth of an inch to achieve balance at the 25 to 30% from wing leading edge (that's about 7.25inches from firewall). That seemed to be the best location for me. With a different motor and battery, you will probably have to do the same. Just get all the electrics in her, hold her on your fingertips about 2inches out from fuse on the wing, and see where she balances. Try moving the battery to achieve the cg, If that isn't enough, move the wing in small increments and glue a piece of foam to the fuse top to provide a stop once you find the sweet spot.

When you laminated the step to main wing bottom, did you get full coverage with the glue? That makes the wing a lot stronger. Also, note the need for a dowell on leading edge. I don't think I spent much time discussing that in the build guide, but basically, you get a 3ft or 4ft 1/8th inch dia dowel, use hot water to soften it at the center, and bend to the dihedral angle, then use a bit of sandpaper on a skewer or another piece of dowel and sand a groove in wing LE, then glue the dowel into the groove. I use gorilla glue there as well, and wrap the LE with a strip of packing tape. Makes a significant contribution to strength/stiffness, and dent resistance for those tree attacks!

The longest I've flown that I kept track of was 25min. but that included several trips up high and long glides down looking for thermals, and the battery hadn't hit lvc yet. On a good thermal day one could stay up indefinitely!

Confused


Is the wingstep 4 inchs glued to bottom of the wing or is it 2 inchs one on top of each other ? Another way to ask do you cut out two steps and then glue them to bottom of the wing ?

How to hit thermals is the biggest challenge to gliding. I don't hope to be able to tell you in a short reply, but suggest you lurk the Gliders forum a bit further down the RCG main page. They have several threads just on how to tell where they are, how to detect if you're in one, etc. Very interesting reading! On the motor, I expect you can make it work, but you will be way nose heavy, and have to compensate with battery or/and wing repositioning. Should make her fly fast, I wouldn't do it until you get the reinforcing dowels in the wings. You are definitely going into the experimenting mode with it.

tabcat: the steps are 2" wide and one goes under each half of the main wing piece. I'll make a picture for you.

My motor and props that you suggested are somewhere between China and Florida! They left China on the 12th. Time to clear off some table space in my studio and break out the foam.
