Replacement wing question

[tomlogan1]

I am replacing the wing on an existing plane. The original wing has a 37 inch wingspan with a 5 inch chord. The new wing which will handle two motors. The wingspan is 48 inches with an 8 inch chord.

My question is can I use the original fuselage with the much larger wing area?

Thank you.

The new wing is going to have twice the area of the old wing, that might be a bit much. But it's hard to tell with the information given.
A good flying plane in that size range will have a wing loading in the range of 10-15 Oz per square foot of wing area. I have had planes that were difficult to land due to the wing being too large. As I recall, the wing loading was around 7 Oz per sqft. I build a smaller wing & it flew great.

The bottom line, the plane will fly with the larger wing but may be challenging to land.

With the two motors, larger wing, battery , the old wing saddle may have to be reshaped and moved fwd or aft to get the CG rage of 25 to 30% of the wing. Also, you can play with the incidence of the wing to a small amount change the lift and stability of the plane. Sounds like a fun project. Now put a shuttle or a small balsa glider on it and release it in the air for a flydown. That's fun.
