Aren't the fins from the Eggspress the same as the EggCrate?
I have 2 of the Eggspress kits opened. The fins were die-punched.
Should I post a jpeg of them with dimensions or are you set already?

Also, where did you find that RED fin can?
Or did you paint it that way.

I was playing around with the Semroc balsa part equivalents last nite.
The 1340/20 clone is WILD when you replace both the #13 and #20 tubes with 34" long pieces!
It should cruise slow and sweet on an E9!

Interesting note---- the yellow plastic cone and transition weight LESS than the balsa equivalents.

Without motor mount and recovery device, the complete mock-up of plastic weighed 94 grams where the balsa came in at an even 100 grams.
