After the sucessful but short lived Hurricane I bought a Hellcat kit.
The first thing I did was weigh the kit wood. The lighest sheets were 2.7g but there were was one sheet (A) which was very very heavy (see picture). The remaining two sheets were around 5.1g. The A sheet must be the heaviest and densist balsa I've ever seen, infact it was off the charts I have to grade it.
I took all of the bits from the very heavy sheet and I cut round round them out of 8.5lb balsa, the middle weight sheets were sanded to 1mm thick and only the fuselage formers were used, the stab parts, wing parts and trailing edges ere re-cut as were the leading edges from the very lightest sheets.
