FSX/P3D. The IRIS Airforce Series - Battlefield Airlifter Version 1.1 is now available for those who have purchased it directly from IRIS. To download the product, please log into your IRIS Store account and download the installer from your ORIGINAL IRIS Platinum Series C-27J Spartan or IRIS Airforce Series Tactical Airlifter product invoice. Please note that this version does NOT contain a working manual, however the product content is complete other than that. A manual is being worked on and should be available within 24-48 hours. In addition, once that is available, all installers will be updated and issued to the usual distributors for sale. To aid in the operation of the aircraft the developers will be creating a number of small youtube tutorials to assist those wishing to fly the aircraft. Like me!
