There is also a pending TAC Pack bundle that includes all but the 2 seater, I believe. I bought the pre-release upgrade but it's been posted on their FB as being on short final to launch. I also have both products and quickly hangared the Prowler as it is indeed dated and has little functionality. The Corsairs are pretty decent rigs, but I've stopped flying awaiting the upgrade. If you're only interested in a particular variant, the sale may be worthwhile, however, if you desire TAC Pack and multiple variants upgraded, you may want to wait out the sale. Just my .02.
