Target weight for 500-series P-40

Post by dirk gently »

Hello,

assuming the use of kit rubber and prop, what is the desired AUW of the model?
The wood in my kit was super-heavy at 0.26g/cm^3, and the model came up at a whooping 36g weight, despite leaving off the undercarriage and using light esaki for covering instead of the kit tissue. I kind of doubt if it will fly with a weight like this.

31g's should be fine if it's painted and ready to fly

Thin out frame of the tail and horizontal stabilizer, Trim down the A keels aft of B4. then if you still need to save weight, thin out the E pieces of Wing. You can also work the the insides of the fuselage formers if you are super into making it as light as possible.
