I no longer use E9-4 engines for my Executioners or scratch built rockets since I now use EconoJet E20-4W's.
I have one E9-4 engine I would like to trade before the trading deadline (that's a baseball joke).
A D12-5 straight up.
A C11-5 and an engine to be named later.
Two B6-4's and a future draft pick. (Football joke).
Any size nylon parachute.
Two CMASS hotdogs or a hotdog and a drink.
