First foamboard scratch build help

OK I got myself a 280 with a 4:1 geardrive and I want to build a plane like a litestick FD and I have some foamboard from the craft store but I have no idea what size to make the wings, With a 280 would anyone be able to help on this. This is my first attempt at building anything like this and all my planes have been in the S400 class and fast so I would like to make something to have those 5-10 mph pilon races with in a smaller area. Thanx for any help.

hmmmm ...... there's a guy building a litestick clone from blue fan fold using a 24" wingspan and a 7" chord for the GWS. I would think you could increase your wingspan from that a bit. Maybe 32"-40" and keep the same chord. You could always start with 38" and trim it back if needed. Your foamboard will be lighter than our fan fold and the 280 geared 4:1 ought to be plenty of power. Be sure to spar your wings and you'll be fine.

After playing with this gearbox a little and could not believe how much thrust it had with the supplied props of 180x145 mm or close to it is 7x5.7, I plan to use a larger prop with a little less pitch but this little motor shocked me on how much power it had. I started working on it tonight and decided to go on the larger side and made a 44" wing span with a 10" cord. I took some bad quality pics but at least you can see where I'm at so far, I have the wing taped together right now but will be adding a good spar and gluing it later.

Looking good Dauntae.

Let me see 44x10 = 440 in sq. She's going to be a floater if that 280 can pull it. Also remember that your horizontal stab will need to be about 20% of your wing area and plan accordingly. You can always trim it down if the weight ( or drag ) is to much.

Should be a neat plane!
